DAIKIN FWT03HATVMV1 (01) PDF Document

When dealing with the DAIKIN FWT03HATVMV1, strictly observe the following safety precautions:

WARNINGS:

• Do not attempt to install the air conditioner yourself. Ask a dealer or qualified person. Improper installation may result in water leakage, electric shocks, or fire.
• The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.
• Install the unit on a foundation strong enough to withstand its weight to prevent falling.
• Electrical work must be performed in accordance with relevant local and national regulations. Use a dedicated power supply circuit only.
• Do not use tapped wires or an extension lead.
• Ensure all wiring is secured, specified wires are used, and there is no strain on terminal connections.
• Do not pull out the power cord when the power is ON as this may cause serious electrical shocks.

CAUTIONS:

• Do not install the unit where there is a danger of flammable gas leakage.
• Install drain piping to ensure proper drainage and insulate piping to prevent condensation.
• Ensure the unit’s panel is closed after service or installation.
• Avoid sharp edges and coil surfaces which may cause injury.
• Before turning off the power supply, set the remote controller’s ON/OFF switch to the “OFF” position to prevent nuisance tripping.
• Do not rinse the unit. This may cause electric shocks or fire.

The DAIKIN FWT03HATVMV1 indoor unit should be sited in a place where:

• Both air intake and exhaust have clear paths.
• The unit is not in the path of direct sunlight.
• The unit is away from sources of heat or steam.
• There is no source of machine oil vapour (this may shorten indoor unit life).
• Cool air is circulated throughout the room.
• The unit is away from electronic ignition type fluorescent lamps (inverter or rapid start type) as these may shorten the remote controller range.
• The unit is at least 1 metre away from any television or radio set to avoid interference.
• The installation height is more than 2.3m.
• The unit is not installed at or near a doorway.
• The unit is not used in a laundry room, as it is not intended for such use.

The dimensions for the DAIKIN FWT03HATVMV1 are as follows:

Follow these steps to connect the chilled water piping:

1. Remove the valve cap from the valve joint.

2. Connect the chilled water return piping (field supply), followed by the chilled water supply piping (field supply).

3. It is recommended to use flexible pipes to connect chilled water supply and return to the valve joint for easier installation.

4. Use a torque wrench when tightening the nut. The recommended torque is 21-23Nm for the joint connection.

Valve Specifications:

• Valve Type: 3 way
• DN: 15
• G: 3/4″

The electrical specifications for the DAIKIN FWT03HATVMV1 are:

• Voltage Range: 220-240V / ~ / 50Hz + Ground
• Power Supply Cable Size: 1.5 mm² (minimum)
• Number of Conductors: 3
• Recommended Time Delay Fuse: 2 A

Important Wiring Instructions:

• All wires must be firmly connected.
• Make sure wires do not touch piping or moving parts.
• The connecting wire to the indoor unit must be clamped using the provided cord anchorage.
• Power supply cord must be equivalent to H07RN-F.
• Do not connect wires of different gauges to the same terminal.

The printed circuit board has 3 jumper options to control the unit operation when room temperature achieves the user set temperature:

Note: During heat mode, the fan will stop eventually to prevent cold drafts to the user.

Do NOT operate the system before the following checks are confirmed:

• The indoor unit is properly mounted.
• The system is properly earthed and the earth terminals are tightened.
• The fuses or locally installed protection devices are installed according to documentation and have NOT been bypassed.
• The power supply voltage matches the voltage on the identification label of the unit.
• There are NO loose connections or damaged electrical components in the switch box.
• There are NO damaged components or squeezed pipes on the inside of the indoor units.
• There are NO water leaks.
• The chilled water pipes are thermally insulated.
• The correct pipe size is installed and the pipes are properly insulated.
• The water valve on the indoor unit is fully open.
• Field wiring has been carried out according to the manual and applicable legislation.
• Drainage flows smoothly to prevent condensate water dripping.
• The indoor unit receives signals from the user interface.

IR Signal Receiver Sounds:

• ON to OFF: 1 Long Beep
• OFF to ON: 2 Short Beeps
• Others: 1 Short Beep

LED Indicator Lights (Normal Operation & Fault Conditions):

The operating limits for the DAIKIN FWT03HATVMV1 are:

• Thermal carrier: Water
• Minimum water entering temperature: 6°C
• Maximum water entering temperature: 50°C
• Maximum water pressure: 16 bar
• Maximum water differential pressure: 1.6 bar

Air Temperature Limits:

Instructions for drain piping installation:

• The drain hose should be inclined downward to ensure flow.
• No trap is permitted.
• Do not put the end of the hose in water.
• When the drain hose requires extension, obtain a commercially available extension hose (Inside diameter 16mm). Be sure to thermally insulate the indoor section of the extension hose.
• When connecting a rigid polyvinyl chloride pipe (inside diameter 16mm) directly to the drain hose, use a commercially available drain socket (inside diameter 16mm) as a joint.

After installation, remove the air filters and pour some water into the drain pan to check that the water flows smoothly.

The technical data for the DAIKIN FWT03HATVMV1 is as follows:

Before performing maintenance on the DAIKIN FWT03HATVMV1:

• ALWAYS switch off the circuit breaker on the supply panel, remove the fuses, or open the protection devices of the unit.
• Do NOT touch live parts for 10 minutes after the power supply is turned off because of high voltage risk.
• Note that some sections of the electric component box are hot.
• Make sure you do NOT touch a conductive section.
• Do NOT rinse the unit as this may cause electric shocks or fire.
• Before performing any maintenance or service work, touch a metal part of the unit to eliminate static electricity and protect the PCB.
