Before each use of the spa and with the unit operating, push the TEST button on the breaker. The switch should click over to the “Trip” position. Wait 30 seconds • Install your spa in such a way that drainage is away from the electrical compartment and from all electrical components. DO: • Be sure your spa is connected to the power supply correctly - use a licensed electrical contractor. • Disconnect the spa from the power supply before draining the spa or servicing the electrical components. • Test the Ground Fault Circuit Interrupter(s) before each use. DON’T: and reset the GFCI breaker by switching it completely off and then completely on. The switch should then stay on. If the interrupter does not perform in this manner, it is an indication of an electrical malfunction and the possibility of an electric shock. Disconnect the power until the fault has been identified and corrected. IMPORTANT: Failure to wait 30 seconds before resetting the GFCI may cause the spa’s Power Indicator (on the control panel) to blink. If this occurs, repeat the GFCI test procedure. • Use the spa with the equipment compartment door removed. • Place electrical appliances within 5 feet (1.5m) of the spa. • Use an extension cord to connect the spa to its power source. The cord may not be properly grounded and the connection is a shock hazard. An extension cord may cause a voltage drop, which will cause overheating of the jet pump motor and motor damage. • Attempt to open the electrical control box. There are no user serviceable parts inside.

RISKS TO AVOID DANGER: RISK OF INJURY • DO NOT sit in the filter compartment area. Sitting in this area can cause: a) Restriction of Filter Pump suction/ vacuum b) Damage to components • Both can result in bodily harm. Should damage occur to components in this area, replace immediately! To reduce the risk of injury to persons, DO NOT remove floating weir, basket, and filter located in the filter compartment while the spa is running. • The suction fittings in the spa are sized to match the specific water flow created by the pump. Never replace a suction fitting with one rated less than the flow rate marked on the original suction fitting. • There is a danger of slipping and falling. Remember that wet surfaces can be very slippery. Take care when entering or exiting the spa. • Never operate spa if the suction fittings are broken or missing. • People with infectious diseases should not use the spa. • Keep any loose articles of clothing or hanging jewelry away from rotating jets or other moving components. Increased side effects of medication • The use of drugs, alcohol or medication before or during spa use may lead to unconsciousness with the possibility of drowning. • Persons using medications should consult a physician before using a spa; some medication may cause a user to become drowsy, while other medication may affect heart rate, blood pressure, and circulation. • Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use the spa. Health problems affected by spa use • Pregnant women should consult a physician before using spa. • Persons suffering from obesity or with a medical history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should consult a physician before using spa. Unclean water • Keep the water clean and sanitized with correct chemical care. The recommended levels for your spa are: Free Available Chlorine (FAC): 3.0-5.0 ppm Total Alkalinity: 40 - 120 ppm Water pH: 7.2 - 7.8 Calcium Hardness: 50- 150 ppm IMPORTANT: Turn jet pump on for at least ten minutes after adding ANY spa water chemicals into the filter compartment. • Clean the filter cartridge monthly to remove debris and mineral buildup which may affect the performance of the hydromassage jets, limit the flow, or trip the high-limit thermostat which will turn off the entire spa. AVOIDING THE RISK OF HYPERTHERMIA Prolonged immersion in hot water can result in HYPERTHERMIA, a dangerous condition which occurs when the internal temperature of the body reaches a level above normal (98.6°F, 37oC). The symptoms of hyperthermia include unawareness of impending hazard, failure to perceive heat, failure to recognize the need to exit the spa, physical inability to exit the spa, fetal damage in pregnant women, and unconsciousness resulting in a danger of drowning. WARNING: The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.

Many problems can easily be diagnosed over the telephone by an Authorized Service Technician. INSTALLATION

PLANNING A LOCATION FOR YOUR SPA Consider these things when determining where to place your spa. SAFETY FIRST: Make sure your spa is positioned so access to the equipment compartment and side panels will not be blocked. Be certain your installation will meet all city and local safety codes and requirements. PLANNED USE OF SPA: How you intend to use your spa will help you determine where you should position the spa. For example, will you use it more for recreational or therapeutic purposes? If your spa is mainly for family recreation, leave plenty of room around it for activity and lawn furniture. If you will use it more for relaxation and therapy, you’ll probably want to create privacy around the spa. PRIVACY: Think of your surroundings during all seasons to determine your best privacy options. Consider the view of your neighbors when you plan the location of your spa. VIEWS: Think about the direction you will be facing when sitting in your spa. Do you have a special landscape you will find enjoyable? Perhaps there is an area that has a soothing breeze during the day or a lovely sunset in the evening. ENVIRONMENT: If you live in a climate with a snowy winter and hot summer, a place to change clothes or a house entry near the spa is convenient. A warmer climate may require shade from the hot sun. Consider placement of trees, shrubs, patio cover or perhaps a gazebo structure to provide what you will need. Indoor installations require adequate ventilation. When the spa is in use, considerable amounts of moisture are produced. This moisture can damage walls and ceiling surfaces over time. Special paint 5 is available to resist moisture damage. Remember that spas periodically require drainage, so plan your environment accordingly. KEEP CLEAN: Prevent dirt and foliage from being tracked into your spa by utilizing concrete for paths and access areas. Check the location of spill paths from gutters, trees, and shrubs. SERVICE ACCESS: Many people choose to install tile or custom wood around their spas. If you are installing your tub with custom decorative trimming, remember to allow for access to it for service. Should you need service, a technician may need to remove the tub’s door panel, or access it from beneath. It is always best to design special installations so the spa can still be moved, or lifted from the ground. A GOOD FOUNDATION: Your new spa needs a good solid foundation. The area your spa sits on must be able to support the spa, the water in it and those who use it. If the foundation is inadequate, it may shift or settle after the spa is in place, causing stress to the shell or components. NOTE: Do Not shim your spa in any manner, as this could cause the cabinet to warp, thereby voiding the warranty. BE AWARE: Damage caused by inadequate or improper foundation support is not covered by the spa warranty. It is the sole responsibility of the spa owner to provide a proper foundation for the spa. Make sure the foundation where the spa is placed drains water away from the spa. Proper drainage will keep components dry from rain and wet weather. Your spa weight must always be considered when installing your spa. If you are installing it on an elevated wood deck or other structure, it is advisable to consult a structural engineer or contractor to ensure the structure will support the weight.

INSTALLATION 6 IT IS STRONGLY RECOMMENDED THAT A QUALIFIED, LICENSED CONTRACTOR PREPARE THE FOUNDATION FOR YOUR SPA. PLANNING A DELIVERY ROUTE: Check the width of gates, doors and sidewalks to make sure your spa will pass through A reinforced concrete pad at least four inches thick is recommended for your spa. The reinforcing rod or mesh in the pad should be attached to a bond wire. INDOOR INSTALLATION: unobstructed. You may have to remove a gate or part of a fence to allow for adequate width clearance. If the delivery route will require a 90-degree turn, check the measurements at the turn to ensure the spa will fit. Check for protruding gas meters, water meters, A/C units, etc., on Be aware of some special requirements if you place your spa indoors. Water will accumulate around the spa, so flooring materials must provide a good grip when wet. NOTE: The Ice your home which will cause obstructions along the delivery path to your yard. Check for low roof eaves, over hanging branches or rain gutters that could be an obstruction to overhead clearances. Bucket drain on the Monterey and Azure spas are designed to drain at the bottom exterior of the spa. Therefore, any water accumulated at the backside of the spa is probably water draining from the Ice Bucket, and not a spa leak. Proper drainage is SPECIAL CIRCUMSTANCES: The use of a crane for delivery and installation is primarily to avoid injury to your spa, your property or to delivery personnel. essential to prevent a build-up of water around the spa. When building a new room for the spa, it is recommended that a floor drain be installed. The humidity will naturally increase with the spa installed. Water may get into woodwork and produce dryrot, mildew, or other problems. Check for airborne moisture’s effects on exposed wood, paper, etc. in the room. To minimize these effects, it is best to provide plenty of ventilation to the spa area. An architect can help to determine if more ventilation must be installed. PLACING THE SPA CHECK THE DIMENSIONS OF YOUR SPA: Compare the spa dimensions to the width of gates, sidewalks, and doorways along the delivery route used to bring the spa into your yard. It may be necessary for you to remove a gate or partially remove a fence in order to provide an unobstructed passageway to the installation location. Also, keep in mind—if you are using special equipment to place your spa into an area it will be necessary to include those measurements and weights.

Follow all owner manual power connection instructions. Installation must be performed by a licensed electrician and all grounding connections must be properly installed. WARNING! DO NOT ENTER SPA IF WATER IS TOO HOT Water is too hot. Overheat protection heater is deactivated. Spa water temperature is above acceptable limits. When the actual water temperature is approximately 2o F (1o C) above the set temperature, the jet pump will stop operating to reduce (frictional) heating. If the spa water temperature continues to rise and gets above 108o F (42oC), the spa will go into an “OH” overheat condition. 13

SPA COMPONENT OPERATION AIR CONTROL VALVE The air control valve serves to regulate the amount of air mixed with the water when the jets are operational. Turn the air control valves in one direction to increased jet action. Rotating the air control in the opposite direction to turn air off and allow the jets to work with water only. Turn the air controls off when the spa is not in use, this will prevent cold air from entering the spa and will keep heating cost to a minimum. The ozone jet, will always produce air bubbles when pump is on. DIVERTER VALVE (WHEN EQUIPPED) The diverter valve on your spa allows you to direct the flow of water from the pump to one of two combinations of jets. The function of the diverter valve can best be learned by experimentation. Turn the large valve all the way to one side or the other to see which jets are on. WHIRLPOOL JET (WHEN EQUIPPED) The Whirlpool Jet is located below the water line at or near the control panel area, in the wall. This jet is a diverter valve and high capacity jet that has a larger diameter than the hydrotherapy jets. The whirlpool jet is turned on and off by rotating the jet face. Because, there is a substantial amount of water pressure when the jet is in operation, you must turn the pump off or to low speed before attempting to rotate the jet face. As the whirlpool jet open position is increased it will begin turning off all of the hydrotherapy jets. One of the two air control valves is dedicated to the this jet. HYDROTHERAPY JETS The hydrotherapy jets are recessed in the wall of the spa. Rotate the medium jet faces to turn the jets on or off. Turning a jet on or off will increase or decrease the effects of any jets not in the closed position. OZONE GENERATOR (OPTIONAL EQUIPMENT) The ozone system enhances the quality of the spa water when used to supplement the spa owner’s regular water maintenance program. Contrary to some information circulated throughout the pool and spa industry regarding ozone systems, ozone CAN'T be used as a single-source sanitizer, water clarifier, anti-foamer, and mineral chelating agent. A secondary source sanitizer must be used to maintain 3.0 -5.0 ppm of Free Available Chlorine (FAC). Watkins Manufacturing Corporation recommends that a chemical maintenance program based on recognized and documented industry standards still be followed when using an ozone purification system to assure water sanitation and the highest quality purified water. WATERFALL (WHEN EQUIPPED) Your spa has a control valve to operate the amount of flow through the waterfall from no flow to a steady stream. This valve is attached to the waterfall.


The following procedures should be followed on initial startup and whenever the spa is drained for routine maintenance. FILLING THE SPA WITH WATER 1. Clear all the debris from your spa. 2. Be sure to open all jets to allow as much air as possible to escape from the plumbing during the filling process. 3. Insert a garden hose into filter compartment to fill your spa. NOTE: Do not use hot or softened water. 4. As the water level rises, check inside the equipment compartment for water leaks. It may be necessary to tighten unions and/or fittings that may have loosened during delivery. There is no need to call for service; this can easily be done. If assistance is required, contact your local Dealer. 5. Under normal circumstances keep the water level half way between the top of the spa and the top of the gray filter ring or just above the highest jets (whichever is higher). Failure to keep enough water in your spa may result in damage to your system and invalidate your warranty. If your spa filter is sucking in air causing the pump to cavitate, you need to add water! IMPORTANT: Loosen drain cap and allow water to exit hose bib for 5 seconds to help prime the jet pump, then tighten drain cap. If the jet pump still is not primed after running repeat step. 6. Check the filter installation and make sure the filter is not loose. APPLYING POWER 1. Turn power to spa "ON" (after filling spa) from the main panel at the house and the subpanel. 2. Press the Jets button on the topside control panel to activate the spa. Rotate all the air control valves counterclockwise and observe the increased jet action (air mixed with water). 3. While the pump is running check again for

water leaks at the drain, unions, or fittings in the equipment compartment (leaks may have occurred during transit). If water is leaking from one of these areas, there is no need to call for service. Simply tighten the fitting. If assistance is required, contact your local Dealer. 4. After checking your spa for leaks it is now time to adjust your spa settings. Press the Plus or Minus button on your topside control panel until the display indicates your desired temperature is set. UNIONS 15 ADDING START-UP CHEMICALS WATER CHEMISTRY GUIDELINES The following step-by-step instructions are a recommended guideline for balancing water chemistry. If unsure about any step in the process, please contact your local Dealer. Initially, it is advisable to identify what minerals (e.g. iron) are present in the local source water. This will provide a better understanding of how to treat the water. Please follow the four steps below and be sure to achieve the correct levels in each area before moving onto the next step. ADD all chemicals into filter compartment while running jets for 10 minutes. STEP LEVEL: #1: ESTABLISH PROPER PH The recommended range for pH is between 7.2 and 7.8. If the reading is too high, lower the pH by using a pH Down/Decreaser (sodium bisulfate). If the pH level needs to be increased, do so with a pH Up/Increaser (sodium hydrogen carbonate). Any pH Up or Down should be added one teaspoon at a time, waiting one-half hour between application and re-measuring. STEP #2: MEASURE TOTAL ALKALINITY: The ideal range is between 40-120 parts per million (PPM). If the total alkalinity is too high, it should be reduced by using an Alkalinity Down/Decreaser (sodium bisulfate). If the total alkalinity is too low, it can be increased by adding an Alkalinity UP/ Increaser (sodium bicarbonate or sodium hydrogen carbonate). These products should be added in small amounts – a teaspoon at a time. After adding one teaspoon, wait one half hour before re-measuring. Once the safe range of total alkalinity is established, proceed to the next step. STEP HARDNESS: #3: DETERMINE CALCIUM It is important to bring the calcium reading to between 50-150 PPM. If the reading requires adjustment, it should now be corrected. If the water is too soft (a low reading) calcium hardness should be added to the water to increase the PPM reading. If the water is too hard (a high reading), it can be corrected by either: (A) a mixture of hard and soft water added to attain a reading in the safe range, or (B) addition of stain and scale control. If calcium hardness is a problem with the local source water (either too hard or too soft) a test kit, which measures calcium hardness, is essential. STEP #4: SANITIZING: After steps 1-3 are complete, the spa must be sanitized using Chlorine (sodium dichlor). Add 2 teaspoons of Chlorine, and increase as necessary to reach a level of 3-5 ppm. Check and maintain this level weekly, and before and after using the spa. IMPORTANT NOTE: A granulated sodium dichlor is highly recommended for sanitizing spa water, granular bromine may also be used. Never use compressed sanitizers even with a floater. As with any other chemicals, the sanitizer should be introduced to the spa with the jets running for 10 minutes. WEEKLY SHOCK: Using a potassium monopersulfate (MPS) shock, add approximately 2 oz. over the filter while the jets are running. Shocking is achieved by adding the MPS to turbulent water. Leave the cover up and jets on high for 10 minutes. Then shut jets off and return the cover to the closed position to maintain heat. 16 SPA MAINTENANCE

FILTER CARTRIDGE MAINTENANCE Every month, the filter cartridge should be cleaned to remove the objects and particles that have lodged in the cartridge pleats. Using household water pressure and a garden hose with a pressurized nozzle, push water from inside to outside of the pleats, forcing all the trapped particles out. NOTE: Never run your spa without a filter cartridge!!! This will invalidate your warranty. NOTE: Filter cartridges should be replaced every six to eight months or earlier when needed. Dirty filters can cause your spa pump to burn out and will invalidate your warranty. FILTER CARTRIDGE REMOVAL AND CLEANING INSTRUCTIONS Spa uses a screw in filter cartridge that is easily removed. • Turn off the power to the spa, (by turning OFF the subpanel breaker). • Push down slightly and turn filter basket counter clockwise to unlock, then pull the basket and weir out. • Unscrew the filter cartridge counter clockwise and bring it out of the spa (requires many turns). • Rinse cartridge using a garden hose. Rotate and separate filter pleats while spraying water to remove all dirt and debris possible. Let filter dry and look for calcium deposits (scaling) or an oil film. If you find these, you will need to deep clean your filter cartridge with a “spa filter cleaner” solution to break down and remove unwanted deposits and oils. (For longer filter life you should soak filter regularly). CAUTION! Always use proper eye protection when using chemicals, or high-pressure water. Read instructions on cleaning products and follow applicable safety and warning instructions listed on label. CAUTION! Never scrub the filter cartridge with a brush, as this will cause the filter to wear out and come apart. Never let the spa pump run without a filter cartridge in the skimmer compartment. Running the spa without a filter cartridge may permit debris to enter the spa plumbing and void the warranty! • Replace filter cartridge, then reinstall basket and weir, (insert and rotate clockwise to lock into position). DO NOT OVERTIGHTEN! • Turn spa’s power back on. 17


SURFACE CARE Do not use solvents or abrasive cleaners to clean the spa. Typically, a mild detergent and water will resolve cleaning issues. COVER CARE Please keep your cover free from dirt at all times. Use a cover cleaner or a warm mild soapy water to clean the surface. Do not use any silicone-based products, as it will dry and may eventually crack the vinyl. NOTE: Do not stand on the cover at any time. Remove the cover when adding chemicals to your spa. This will extend the life of your cover. The gasses from burned off chemicals will be trapped under the cover, if not removed. These gasses may erode the protective lining of the foam inserts. This will not be covered under warranty. CABINET CARE Little maintenance is required to keep your spa cabinet looking good. Spa cabinet product should be cleaned as needed to remove dirt and debris. • NO abrasive or harsh chemicals should be used on the spa's cabinet. • NO solvents or cleaners containing aromatic solvents should be used on the spas cabinet. • Hot soapy water is the best choice for cleaning the spa's cabinet. SPA LED REPLACEMENT • Turn OFF the power to the spa. • Remove the equipment compartment access door. • Locate the rear of the spa light. • To remove the LED board, turn outside housing counter clockwise 1⁄4 turn, and pull out and remove LED board from socket. • Replace by reversing the above steps. 18


Every three to six months, depending upon the water condition, you need to renew your water. CAUTION: READ THIS BEFORE DRAINING YOUR SPA • To prevent damage to the spa’s components, UNPLUG GFCI CORD OR TURN OFF SUBPANEL BREAKER BEFORE DRAINING. Do not power back up until your spa has been refilled with water. • There are certain precautions to keep in mind when draining your spa. If it is extremely cold, and the spa is outdoors, freezing could occur in the plumbing or the equipment. • Do not leave the spa's shell (inside surface) exposed to direct sunlight. DRAINING YOUR SPA • If draining for the first time, pull the hose bib out a few inches from the spa (located in the recess under the spa). • Unscrew and remove the drain cap. • Attach hose bib to a garden hose and direct to an appropriate draining area, keeping the hose below the water line. • After your spa is empty, clean the shell and filter cartridge. See “Spa Maintenance” section. • After cleaning, remove garden hose, replace drain cap and push the hose bib back into the recess. • Follow the “Fill up and Start-up Instructions” on page 15. WINTERIZING YOUR SPA If you plan to store your spa for the winter, you must also use a wet-vac to clean out the water lines to ensure they are free of any water. Water left in the lines might freeze and damage the lines and jets. 1. It will be necessary to remove all water from the interior plumbing. 2. Remove the floating weir, basket, and filter cartridge. Clean the filter cartridge and store in a dry place. Attach the vacuum hose to the vacuum side of the shop vac and thoroughly dry the filter compartment. 3. Using the shop vac, remove the water starting with the jets at the top and moving to the ones at the bottom of the spa. NOTE: When removing the water from jet openings, you may notice suction coming from another jet. With the help of a second person, block off any suction from the other jet using a large rag or cloth. This will help pull out the water that is trapped deep inside the main line. 4. Thoroughly dry the spa shell with a clean towel. 5. Using a funnel, pour Propylene glycol anti- freeze into the filter suction fittings and jet outlets. CAUTION: Use only Propylene glycol as your anti-freeze. This is non-toxic. NEVER use automobile anti-freeze since it is toxic. 6. Remove the pump drain plug located on the front of the pump housings. Allow all water to drain out. Place the drain plug in a reclosable plastic storage bag and store near the pump. Replace the drain plugs on start-up. 7. Unscrew the suction/discharge pump and heater unions and allow the water to drain. Leave union loose. NOTE: Tighten unions before filling spa. 8. Replace the equipment compartment door and secure with screws. Note: Damage caused by improper winterizing will not be covered under warranty. You may want to contact your local Dealer for proper winterizing. 19


In the event the spa is not working the way it should, please first review all the installation and operating instructions in this manual and check the message on the panel display. If you are still not satisfied it is working properly, please follow the appropriate troubleshooting instructions. CAUTION! WARNING! SHOCK HAZARD! No User Serviceable Parts. Do not attempt service of the control box. Contact your local Dealer for assistance. Follow all own- er's manual power connection instructions. NO COMPONENT OPERATION Check the following: 1. Is there power to the spa? 2. Is the household circuit breaker tripped? 3. Is the subpanel (230V) or cord GFCI (115V) tripped? 4. If 1, 2 or 3 are yes contact your local Dealer for assistance. PUMP DOES NOT OPERATE, BUT THE LIGHT DOES Press the Jets button: The pump operates but no water flows to jets. Pump may not be properly primed. This can happen after the spa is drained and refilled. Press the Jets button several times, never leaving the motor on for more than 5-10 seconds at-a-time with no water coming of of jets. POOR JET ACTION 1. Press the Jets button to make certain the pump is on. 2. Rotate all the air control valves counterclock- wise and observe the increased jet action. 3. Make sure the water level is half way between top of spa and top of the gray filter ring. 4. Check for dirty filter. Clean, if necessary. 5. Make sure all jets are in the open position. WATER IS TOO HOT 1. Check desired temperature on topside control. 2. Check for a Diagnostic Message (in Control Panel Operation section). OH - Overheat (spa is deactivated) DO NOT EN- TER THE WATER. If the spa has overheated you should remove the cover to promote heat reduction. The spa control system should reset itself when the water temperature reduces below 104oF or 40oC. When the spa falls below the reset temperature you can push any button on the topside control to reset the control system. If the spa will not reset, then shut off power to the spa and contact your local Dealer. Under extreme and/or prolonged weather conditions it is possible for the ambient temperature to exceed 106F/41C; effecting the water temperature of the spa and causing it to overheat. These conditions could cause the spa sensors to produce an OH message and prevent the usage of your spa during these conditions. The location of your spa should be reconsidered to reduce the outside temperature around the spa. For example, you may need to prevent direct sunlight on any surface of your spa. Regardless, do not enter your spa if the temperature is above 104°F. Should checking the above steps fail to correct the problem, please contact your local Dealer. 20
