Panasonic WH-SDC03H3E5 Service Manual page 3

Do not use joint cable for Indoor / Outdoor Unit connection cable. Use specified Indoor / Outdoor Unit connection cable, refer to
instruction CONNECT THE CABLE TO THE INDOOR / OUTDOOR UNIT and connect tightly for Indoor / Outdoor Unit connection.
18.
Clamp the cable so that no external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat up or fire
at the connection.
This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective
19.
national wiring rules or country-specific safety measures in terms of residual current.
During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fixing
20. refrigeration piping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in
explosion, injury etc.
During pump down operation, stop the compressor before remove the refrigeration piping. Removal of refrigerant piping while
21. compressor is operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigerant cycle and result in
explosion, injury etc.
Tighten the flare nut with torque wrench according to specified method. If the flare nut is over tightened, after a long period, the flare
22.
may break and cause refrigerant gas leakage.
After completion of installation, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts
23.
with fire.
Ventilate the room if there is refrigerant gas leakage during operation. Extinguish all fire sources if present. It may cause toxic gas
24.
when the refrigerant contacts with fire.
25. Only use the supplied or specified installation parts, else, it may cause unit vibrate loose, water leakage, electrical shock or fire.
The unit is only for use in closed water system. Utilization in an open water circuit may lead to excessive corrosion of water piping and
26.
risk of incubating bacteria colonies, particularly Legionella, in water.
27. If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.
28. Select a location where in case of water leakage, the leakage will not cause damage to other properties.
When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no
29.
electrical contact between equipment and building is allowed. Insulator must be installed in between.
Any work carried out on the Indoor Unit after removing any panels which is secured by screws, must be carried out under the
30.
supervision of authorized dealer and licensed installation contractor.
This unit must be properly earthed. The electrical earth must not be connected to a gas pipe, water pipe, the earth of lightening rod or
31. a telephone.
Otherwise there is a danger of electrical shock in the event of an insulation breakdown or electrical earth fault in the outdoor unit.
Do not install the Indoor / Outdoor Unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at
1.
surrounding of the unit, it may cause fire.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care of the
2.
liquid refrigerant, it may cause frostbite.
3. Do not install this appliance in a laundry room or other high humidity location. This condition will cause rust and damage to the unit.
4. Make sure the insulation of power supply cord does not contact hot part (i.e. refrigerant piping) to prevent from insulation failure (melt).
5. Do not touch the sharp aluminium fin, sharp parts may cause injury.
Do not apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause flooding and damage to
6.
other properties.
7. Select an installation location which is easy for maintenance.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage
8.
the furniture.
Power supply connection to Indoor Unit.

Power supply point should be in easily accessible place for power disconnection in case of emergency.

Must follow local national wiring standard, regulation and this installation instruction.
9.

Strongly recommended to make permanent connection to a circuit breaker.
- Power supply 1: Use approved 15/16A 2-poles circuit breaker with a minimum contact gap of 3.0 mm.
- Power supply 2: Use approved 15/16A 2-poles circuit breaker with a minimum contact gap of 3.0 mm.
10. Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fire.
After installation, check the water leakage condition in connection area during test run. If leakage occurs, it will cause damage to other
11.
properties.
