IMPORTANT SAFETY INSTRUCTIONS READ AND SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE. Means for all pole disconnection must be incorporated in the fixed wiring in accordance with the wiring rules. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. The following specifications for the cooler water supply are required: Min Water Pressure: 15psi (100kPa) Max Water Pressure: 115psi (800kPa) New hose sets supplied with the appliance are to be used and old hose-sets should not be re-used. WARNINGS TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING: 1. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction. 2. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities. 3. Ducted fans must always be vented to the outdoors. 4. Do not use this fan with any solid-state speed control device. EMPLOYER AND EMPLOYEE RESPONSIBILITIES The installation and maintenance of evaporative coolers at height has the potential to create Occupational Health and Safety issues for those involved. Installers are advised to ensure they are familiar with the relevant State and Federal legislation, such as Acts, Regulations, approved Codes of Practice and National Standards, which offer practical guidance on these health and safety issues. Compliance with these regulations will require appropriate work practices, equipment, training and qualifications of workers. Seeley International provides the following information as a guide to contractors and employees to assist in minimising risk whilst working at height. INSTALLER AND MAINTENANCE CONTRACTORS - RISK ASSESSMENT A risk assessment of all hazardous tasks is required under legislation. A risk assessment is an essential element that should be conducted before the commencement of work, to identify and eliminate the risk of falls or to minimise these risks by implementing control measures. There is no need for this to be a complicated process, it just is a matter of looking at the job to be done and considering what action(s) are necessary so the person doing the job does not injure themselves. This should be considered in terms of: • What are the chances of an incident happening? • What could the possible consequence be? • What can you do to reduce, or better still, completely get rid of the risk? SOME POINTS TO CONSIDER • What is the best and safest access to the roof and working areas? • If a worker is alone, who knows they are there and if they get into difficulty, how can they summon help? (Call someone on the ground? Mobile phone? Etc.) • What condition is the roof in? Should the trusses, underside or surface be checked? • Does the worker have appropriate foot wear? (Flat sole jogger type is advisable.) • Are all power cables / extension leads safe and appropriately rated? • Are all ladders, tools and equipment suitable in good condition? • Where ladders are to be used, is there a firm, stable base for them to stand on? Can they be tied or secured in some way at the top? Is the top of the ladder clear of electricity supply cables? • Is there a roof anchor to attach a harness and lanyard to? If so, instruction should be issued for the use of an approved harness or only suitably trained people used. • Are all tools and materials being used, prevented from slipping and falling onto a person at ground level? Is the area below the work area suitably protected to prevent persons walking in this area? • Does the work schedule take into account weather conditions, allowing for work to be suspended in high winds, thunder storms/lightning or other types of weather giving wet, slippery surfaces? • Is there an on-going safety check system of harnesses, ropes, ladders and access/lifting equipment and where they exist on roofs, anchor points before the commencement of work? • Is there a system which prevents employees from working on roofs if they are unwell or under the influence of drugs or alcohol? • Are there any special conditions to consider i.e. excessive roof pitch, limited ground area, fragile roof, electrical power lines? OTHER IMPORTANT REQUIREMENTS • Never force parts to fit because all parts are designed to fit together easily without undue force. • Never drill holes in the pan (Reservoir) of the cooler. • Check the proposed cooler location, to ensure that it is structurally capable of supporting the weight of the cooler, or provide an adequate alternate load bearing structure. Ensure the installation complies with all local and national regulations with regards to electrical, plumbing and bushfire/ wildfire construction requirements.

If the roof is Astructurally inadequate, provide an alternate load bearing structure. DRAIN VALVE ASSEMBLY & FITTINGS SOLENOID The ideal location for the cooler is in a central position on the roof (away from sleeping areas and where people spend most of their time) so that the duct runs are of approximately the same length. Carefully consider neighbouring residences and A - Drain Valve noise levels when locating the cooler, if necessary talk to the B - ‘O’Ring C - Nut D - Drain Adaptor E - Lock Nut Bcustomer and the neighbour before carrying out the installation. Always locate the cooler where it will receive adequate fresh air and not in a recess where it may be starved for air or where the air is polluted. CDSOLENOID FITTINGS Ensure location is a minimum of: • 10’ (3m) from a solid fuel heater flue, • 5’ (1.5m) from a gas flue, • 17’ (5m) from a sewer vent, and E • 2’ (600mm) from a wall. STRAIGHT TUBE (Water Inlet) The cooler must be mounted at least 10’ (3m), preferably 17’ (5m), away from any TV antenna or antenna cables. SOLENOID COVER E FLEXIBLE HOSE ASSEMBLY RUBBER WASHER Make sure the cooler is not between the antenna and the transmission tower that is providing the television signal to the CONTROL home. CABLE Allow adequate access to and around the cooler for maintenance. Provision must be made for access to electricity, water supplies and drains. Note! Do you need to discuss the installation of items like safety anchor points with the customer? CABLE TIE BRASS ADAPTOR 1⁄2”BSP to 1/4” COMPRESSION ILL3385-A EXVQ MODELS XILL1204-C NUT 1⁄2”BSP & OLIVE ACCESS FOR SERVICING AND MAINTENANCE The cooler should be installed in a position that allows adequate access for installation, and future maintenance and servicing activities. This should comply with installation guidelines and any local, State and National regulations. Consider the following for installation location:- • Which has clear access to and around the cooler • Which is clear of fixtures in line with below clearances • Which is clear of fall edges (> 10’ or 3m away) • Which is structurally capable of supporting the weight of the cooler and service technicians Required clearances around the cooler for future maintenance and servicing are shown adjacent.

INSTALLING THE ROOF JACK New Installation Use 24G or stronger metal roof jack. The cooler may then be attached directly to the jack. Replacement Installation Roof Jack recommended wall thickness should be 24G or stronger. The supplied roof jack adaptor may be required to attach the cooler to the existing roof jack. To assemble the roof jack adaptor, hold panels at 90 degrees to one another. Align slots in upper and lower panels then slide together. ILL3363-A Note! It is recommended that a strip of foam or sealant is ILL3 applied to the upper flange on the roof jack before securing the cooler to provide an airtight seal. Ensure that the top of the roof jack is level and square in all directions (use a spirit level). This helps with levelling the cooler. ILL922-B INSTALLATION CONVEYING THE COOLER TO THE ROOF Lifting and installing the cooler is made easier by removing the pad frames first. They can be replaced at the very end of the installation procedure. ILL1667-A Do not slide the cooler, lift and carry it. It is recommended that at least 2 people carry the cooler whenever it needs to be moved. Do not drop the cooler. Always handle with care. Important! For lifting or pulling purposes when using ropes or slings, always apply the ropes around fan housing. Never tie them to any or all of the 4 round corner posts. WARNING! Take care that the ends of ladders, etc. don’t penetrate into the opening of the cooler, as the Weatherseal or the cut-off plate may be damaged. CAUTION! Never try to raise the cooler to the roof alone. MOUNTING THE COOLER Locate the cooler on the dropper with the pan (reservoir) sump on the low (gutter) side of the installation. ILL159-F Fix the cooler to the dropper with 8 self-tapping screws provided (2 screws per side). There are ten screw locations identified by “V” notches. If access to the “high roof side” is limited, use 3 screws on each side and 2 on the front. In exposed or high wind areas, seek advice from a structural engineer. Important! Screw length must be less than 1.5” (40mm) to avoid interfering with the weatherseal. BREEZAIR EXVQ EVAPORATIVE COOLER INSTALLATION MANUAL | 5 6 | INSTALLATION SECURING THE LEG SUPPORTS The telescopic leg supports (with feet attached) slide up and down inside the four corner posts. By removing the screw from the lower end of the corner post you enable the leg support to slide down to roof level. ILL958-A Make sure each leg is vertical before securing. Secure foot to roof with 2 screws (minimum). ILL959-B Maintain downward pressure on corner post as you replace the screw to ensure that the bottom of the corner post is sitting flush with base of corner support (view through “V” notch). Ensure screw is horizontal when replaced. ILL960-A The support legs are not full weight bearing and are only intended for additional support in case of high winds, etc. WEATHERSEAL AND LATCH (Model dependant, refer to Dealer.) Where fitted, the Weatherseal latch performs two functions. In the locked position it acts as a latch, preventing movement during transport. LOCKED POSITION In the operating position it acts as a restrainer, preventing gusts of wind from opening the Weatherseal. Once the cooler is installed on the roof, squeeze the latch and rotate it clockwise to its operating position.

OPERATING POSITION ILL1649-A ILL1650-A Check the Weatherseal moves freely and without obstruction by lifting the latch and rotating counterweighted arm. ILL525-D INSTALLATION ELECTRICAL REQUIREMENTS The main power termination box is provided to facilitate easy wiring connections. Cable glands are provided for 1⁄2” ID conduit. MAIN POWER CONTROL BOX ILL1395-A Terminate the power cable outside of the cooler in a junction box installed nearby. Refer to the field wiring diagram in the previous section. The fixed wiring must be The fixed wiring must be fitted with an all pole disconnection switch that breaks the active (hot) and neutral (common) in accordance with local wiring rules. It is recommended that the junction box be located and installed on the dropper (roof jack). IMPORTANT REMINDER! Do not route extra-low voltage data/communication and low voltage supply mains cables without first consulting your local wiring standards. Routing data/communication cables and supply mains cables in close proximity can present an electrical hazard and can be detrimental to the performance of the product, resulting in intermittent communication errors, locking ILL1898-A up of screens, displays dropping out and inconsistent erratic operation. Installation of the cooler must conform to local electrical rules, regulations and standards. INSTALLING THE CONTROLLER CABLE Important! It is a requirement of Seeley International that Seeley International recommends: all Breezair coolers be connected to a dedicated circuit to the distribution board, with a separate circuit breaker and incorporate all pole disconnection switch in accordance with the local wiring rules. Electrical supply specifications may vary depending on model or region. Please refer to the rating label attached to the cooler for details. WARNING! If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or a similarly qualified person in order to avoid a hazard. • Not routing data/communication and supply mains voltage cables in the same conduit. • Not cable tying or taping data/communication and supply mains voltage cables together. • A minimum separation distance, as specified by your local wiring standards, between data/communication and supply mains cables. In Australia, this minimum separation distance is 2” (50mm). Connect one end of the control cable (with ferrite suppressor) to the cooler electronics box. INSTALLING THE MAINS POWER CABLE This cooler contains an electronics module (control box) with main power supply termination box separated and connected via a cable and plug assembly. The point of entry into the cabinet of the cooler is by knockouts in the pan (reservoir). Seal the gap between the conduit and the knock-out hole with silicone sealant after making connections and clamping the conduit cable. Important! Ensure that all electrical connections are tight. Loose connections will cause overheating that may lead to machine damage or fire. Replace all covers on completion of work, using only the screws supplied. Do not tamper with factory wiring. Before leaving the job, a trained, licensed technician must check that the cooler is operating correctly. LEGEND A - Controller Cable B - Speed Adjustment C - Inlet Solenoid D - Water Sensor Your cooler electronics will have 2 x RJ ports as shown above. For cooler electronics with 2 x RJ ports, the wall control cable can be fitted to either.

The following specifications for the cooler water supply are required: Water Connection 1⁄2” BSP Min Water Pressure 15psi (100kPa) Max Water Pressure 115psi (800kPa) Min Water Flow 2.1 gallons/min (8 liters/min) Max Water Temperature 104°F (40°C) Important! If the water pressure exceeds maximum specification then a pressure reducing valve is required and must be supplied and fitted by the installer. WATER CONNECTIONS A permanent water supply is required to be connected to the cooler. The water connection point is located on the underside of the cooler pan (reservoir). You must install a manual 1/4 turn ball type shut off valve (do not use a stop cock) in the water supply line adjacent to the cooler, subject to local plumbing regulations. This allows the water supply to be isolated whenever work needs to be done on the cooler. COOLERS WITH DRAIN VALVES For coolers with the inlet solenoid valve fitted, the water connection is a 1/2” BSP compression fitting on the end of a flexible hose. The flexible hose is connected to the float valve. The 1/2” BSP Compression fitting can be directly screwed onto the water pipe or be directly screwed onto the manual water shut-off valve. Always ensure that the water pipe connection does not place sideways strain onto the float valve. Important! In areas subject to freezing, the water supply line to the cooler requires a drain down facility at the lowest point in the water supply pipe. Important! Flush the water pipe to remove any swarf before final fitting. Swarf can lodge in the solenoid and float valve, preventing them from functioning correctly. 8 | INSTALLATION INSTALLING THE CONTROLLER CABLE Run the cable to the roof space and then to the controller via the mains power cable entry point and plug in to the rear of the wall control. Note! The maximum length for the wall control cable to travel alongside the power cable is 33’ (10m). WARNING! Do not let the cable, the cable ends, or the control box get wet. Position the cable in the dropper so they will be accessible from inside the roof space. INSTALLING THE INLET SOLENOID For coolers fitted with a drain and solenoid valve, it is a requirement to fit the new detachable hose set as supplied. Any old hose sets should not be re-used. For EXVQ model coolers, fit the inlet solenoid under the pan (reservoir) as shown: IBE DAGCFJUse NOTE: thread Lead seal must tape wrap between underneath solenoid solenoid barrel hose assembly and brass 1⁄2” BSP to 1⁄4” compression adaptor or 1⁄2” BSP Nut. Note! Tighten the solenoid valve until it seals against the rubber washer and is in the orientation shown such that the solenoid cover will clip on over the top. The water solenoid is required to be installed in the direction of flow as per the arrow indicator on the solenoid. ILL1676-A Ensure washers are correctly located. Do not over tighten plastic fittings. Insert the solenoid cable through the hole in the cooler pan (reservoir) (behind the drain valve) and connect to the water solenoid valve. Make sure the cable is fitted to the groove underneath the pan so it does not get trapped by the solenoid cover when fitted. The cable leads can be connected to the solenoid either way around. Important! The cable must wrap underneath the solenoid. while cover is attached.

Make sure the solenoid valve cable is retained in the groove in the cooler pan (reservoir). Secure the cover by tightening the flexible hose assembly nut (C). Important! Make sure the cable cannot lay in the water at any stage. Connect the electrical leads to the solenoid. Refer to the installation manual provided with the wall controller for instructions on installing the controller. Coolers are supplied with a 66’ (20m) control cable. Longer cable lengths are available from Seeley. Important! The maximum cable length allowed from the MagIQtouch controller to the first cooler is 82’ (25m). For any additional coolers added into the system with a link module the The electrical cable leads may be connected to the solenoid either way around. Taps or shutoff valves used must not be of the non - return type. Water drained from the cooler must be carried away to a suitable discharge point in accordance with local regulations. maximum allowed length is 131’ (40m). Therefore, failure of the product or components to operate correctly due to modification to supplied cables, or the use of non-approved cables will NOT be accepted under the Manufacturer’s Warranty. We have this cable available through our sales order office and spare parts outlets in the following lengths: INSTALLING THE DRAIN VALVE Water drained from the cooler must be carried away to a suitable discharge point in accordance with local regulations. Important! Never drain water from the cooler directly on to the roof. AB CILL3387-A DEILL746-E Make sure the “O”-ring (B) is fitted before placing the drain valve into the hole. Screw the nut (C) up tightly by hand underneath to locate the drain valve. Locate the drain adaptor (D) up against the bottom of the drain valve thread and secure with the second, larger nut (E). Make sure that you use the correct drain adaptor. Make sure the drain water discharge flows freely away from the cooler. Important! Do not over-tighten plastic fittings.

The motor pulley is adjustable in order to set the motor amperes at the correct (nameplate) level, and thus provide the owner Ensure that all intended doors, windows or other means of with full machine cooling capacity. exhaust are open in the building, and that all outlet grilles are open fully. DO NOT USE THE PULLEY ADJUSTMENT TO SET BELT TENSION WARNING: Beware of rotating fan, belt and pulleys whilst making adjustments to motor speed, pulley or belt tension settings. Ensure the cooler is switched OFF via the electronic module isolation switch whilst working inside the cooler. Set the cooler running at the highest speed for about 10 minutes, or until the motor has reached its normal operating temperature (hot!).Motor load must be checked without the pump running. Clip your ammeter onto the free cable in the main termination box. This should be done by a trained licensed electrician. The adjustment is made with the cooler switched OFF. Never attempt this procedure with the cooler operating. • Remove the drive belt. • To increase the fan speed (and therefore the motor amps), the two halves of the pulley must be closer together, ie: turn the adjustable half clockwise. • To decrease the fan speed (and therefore the motor amps), the two halves of the pulley must be further apart, ie: turn the adjustable half counter-clockwise. ILL1013-D For convenience, the rated motor current, in amps, is printed on a small label attached near the cable fork (in addition to the normal motor nameplate label located at the back of the motor). Check the measured amps against the motor nameplate amps. If the measured amps are less than the nameplate amps the adjustable motor pulley sheave must be altered to increase the fan speed, thereby delivering the full capability of the cooler to your installation. The measured amps must be equal or close to, but never more than the nameplate amps. (see heading “Pulley Adjustment”) If the measured amps are greater than the motor nameplate amps the fan MUST be slowed down by adjusting the motor pulley sheave in the opposite manner. Failure to do this will cause overheating in the motor and may cause the motor’s thermal protector to trip. Replace all covers when adjustments are completed using the screws provided. A = Fixed Sheave B = Grub Screw C = Adjustable Sheave D = Locking Cap E = Locking Cap Screw ILL1208-D The outer half of the pulley is on a thread and can be moved in or out by removing the locking cap and then turning the outer half by hand in the desired direction. When an adjustment is made, replace the locking cap, aligning the screw hole with the nearest hole in the adjustable half. Lock it into place with the securing screw. Refit the belt, reset the belt tension, then run the cooler and check the amps. Repeat the process until the amp level is set. You can start and stop the cooler for this procedure by using the isolating switch inside the cooler.

MOTOR BELT TENSION LOW SPEED SETTING Belt tension is important! If it is too tight there will be excessive belt and bearing wear. If it is too loose there will be belt slip, excessive belt wear and loss of cooler performance. There are two adjuster bolts with locking nuts attached to the motor mounting. The tension should be adjusted so that the deflection on one side of the belt is 5/8” to 13/16”. To make the adjustment, loosen the locking nuts and screw the bolts in or out as required to change the belt tension. Re-tighten the locking nuts. It is important to recheck the motor amps again after re-setting the belt tension. A = Motor B = Deflection 5/8” - 13/16” (15-20mm) with moderate finger pressure C = Blower Housing D = Fan Pulley E = Belt Tension Adjustment Bolts ILL034-J EXVQ coolers will function across a wide speed range. The minimum speed has been factory set, and should not require adjustment under normal circumstances. However, some adjustment may be necessary to suit specific installations. After you have set the motor amps and belt tension correctly, check the speed variation of the cooler. When the control is changed from maximum to minimum settings, there should be an easily recognizable difference in fan speed. If there is not, check the following: • That windows and doors are open. Rule of thumb is to have 2 times the area of the outlet grille open for exhaust in each room. If the above is correct then proceed as follows: • Set the fan speed to minimum using the remote control, so that only two bars are displayed on the remote control. • Turn the minimum speed adjustment knob (“A”) clockwise or anti-clockwise, until the belt is running at approximately one revolution per second (this equates to a fan speed of approximately 600 rpm). ILL1013-D Correct belt tension ensures the belt will not slip. Check the temperature of the belt by hand after each adjustment, by turning off the cooler and holding one side of the belt in your hand. If the belt is warm to touch, it is slipping! Continue to tighten until it runs cool. A + - ON ILL3386-A ON ILL3386-A INSTALLATION

COMMISSIONING FAULT CODES Fault Code 01 (1 Red Flash) = Communication Failure • Ensure wall control cable is fitted correctly. • Check the wall control cable is in good condition. Fault water Code at probes 02 (2 within Red Flashes) 8 minutes = Failure to detect • Ensure water pressure is sufficient to fill and maintain the pan (reservoir) to specified level within 8 minutes. • In areas of hard or polluted water, blockage of the strainer/ filter in the water inlet solenoid valve may restrict water flow. • Water level set too low. For Breezair coolers the water level should be set to 13/64” (5mm) above the float valve base. • Ensure probe plug is properly connected. • Plug connections at electronic module are upside down or misaligned. • Water too pure for the probes to sense water is present. • Pressure build up in pipes can lock up the solenoid valve when a non-return isolation valve is used in the water supply line. It is recommended to use a ball valve, i.e. NOT a non- return type of shut off valve. • Check drain valve is closing and not cycling due to debris being caught under drain valve washer. Fault Code 04 (4 Red Flashes) = Failure to clear probes during drain within 4 minutes • Check the drain valve opens and water drains from the pan (reservoir), with nothing obstructing the outflow of water. (e.g. drain hose kinked) • Excessive drain hose lengths or bends cause air locking and won’t allow water to drain. • Build up of foreign material in drain hose not allowing water to drain away correctly. • Screws used to fix drain hoses to drain adaptors restricting water from draining from pan (reservoir). • Drain valve has failed to open when drain was initiated. • Inlet water solenoid not shutting off water when the drain is open. • Water will only flow one way through the inlet water solenoid valve. Therefore, it must be installed correctly. Directional arrow must be pointing towards the float valve assembly. If not, water will not shut off. (Directional arrow can be found on the bottom of the solenoid valve body). • Debris interfering with water sensor probes. • Probes not clipped onto mounting brackets correctly. • Check cooler is level and water drains quickly. SETTING THE WATER LEVEL Isolate power to the cooler electronics and disconnect the pump, making sure the plug is kept away from any water. Turn the power back on. Turn on the mains water supply to the cooler. Turn the cooler on at the controller, in “COOL” mode. Adjust set temperature slider / fan speed buttons to be close to current room temperature so that fan speed remains low. Allow the pan (reservoir) to fill with water. The float valve will eventually stop the water from entering the cooler. Wait for this to happen and check the water level. If the level is too high rotate the float clockwise. Drain some water from the pan and allow it to refill to the new set point. If too low rotate the float in an anti-clockwise direction. For EXVQ models the correct water level is approximately 13/64” (5mm) above the surface of the pan (reservoir) the float valve is mounted on. ILL1370-B ILL1615-A ILL1663-A

EXVQ MODEL 13/64" (5mm) ILL526-D TESTING THE DRAIN VALVE Select the “SETTINGS” mode on the MagIQtouch Controller and select the “COOLER” sub-heading. Select the “MANUAL DRAIN” option to operate and test the drain valve. ILL1838-B TESTING THE PUMP Test the pump by turning the cooler on at the MagIQtouch controller, in “COOL” mode. Check that water is evenly distributed to all pads. Note! If the cooler has not been on before it will run a “Pre-Wet” routine where the pump will operate to saturate the pads. This cycle takes 2 minutes, then the fan will start automatically. REFITTING THE PAD FRAMES Refit the pad frames by locating the bottom edge in the pan (Reservoir) groove, then push the top in under the lid. Refit the corner clips after replacing the pad frame(s). 2 3 1 ILL1600-A ADJUSTING COOLER SETTINGS Within the SETTINGS menu of the MagIQtouch Controller is the COOLER sub-heading. Here various settings of the cooler can be adjusted. ILL1664-A About Appliance Displays information such as model number, serial number and software version for all coolers connected to the controller. Min/Max Set Temperature Defines the maximum and minimum temperature values. Manual Drain Turns cooler off and drains the pan (reservoir). Pad Flush Turns cooler off and runs pump for a specified amount of time. Drain And Dry Cooler will drain and fan will run for 1 hour every day at a specified time. Water Manager Select the preferred water management method: • Salinity Measurement - replaces water when Salinity level reaches set point. • Timed Drain - drains pan (reservoir) After 8 pan fill cycles or every 1-2 hours (system dependant). • No Drain Control - salinity control external to electronics eg. continuous bleed. • No Water Thermostatic - allows Thermostatic control in VENT mode. No water present. Cooling performance is limited. Weatherseal Open Speed The cooler fan will turn on at the specified Weatherseal opening speed for the first 10 seconds each time it starts up. It will then return to the set fan speed. Prewet When COOL mode is activated, the pump will run for 90 seconds before the fan is switched on. Salinity Level Sets the salinity level at which the pan (reservoir) will drain in “SALINITY MEASUREMENT” mode.

Night Quiet Mode Restricts fan speed to a specified level during a specified period. Humidity Control (when Internal Air sensor is connected) Set desired humidity levels. External Air Sensor Not fitted on EXVQ models. Pan (Tank) Drain Delay Sets the time delay before the drain valve opens after the pump in the cooler is turned off. AutoClean Select the preferred cleaning interval (50 / 100 / 200 hours). At 8.00am after the selected running hours has been reached, the cooler will drain the pan (reservoir), fill with fresh water and operate the pump for 5 minutes. When complete, drains the pan and returns to previous operation mode.
