Panasonic WH-SHF09F3E8 Service Manual page 3

19. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
20. Install at a strong and firm location which is able to withstand the set's weight. If the strength is not enough or installation is not properly done,
the set will drop and cause injury.
21. Do not use joint cable for indoor/outdoor connection cable. Use specified indoor/outdoor connection cable, refer to instruction CONNECT
THE CABLE TO THE INDOOR UNIT and connect tightly for indoor/outdoor connection. 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.
22. This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective national
wiring rules or country-specific safety measures in terms of residual current.
23. During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fixing 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.
24. During pump down operation, stop the compressor before remove the refrigeration piping. Removal of refrigerant piping while 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.
25. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over tightened, after a long period, the flare may
break and cause refrigerant gas leakage.
26. After completion of installation, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts with fire.
27. Ventilate the room if there is refrigerant gas leakage during operation. Extinguish all fire sources if present. It may cause toxic gas when the
refrigerant contacts with fire.
28. Only use the supplied or specified installation or servicing parts, else, it may cause unit vibrate loose, water leakage, electrical shock or fire.
29. The unit is only for use in a closed water system. Utilization in an open water circuit may lead to excessive corrosion of water piping and risk of
incubating bacteria colonies, particularly Legionella, in water.
30. If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.
31. Select a location where in case of water leakage, the leakage will not cause damage to other properties.
32. When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no electrical
contact between equipment and building is allowed. Insulator must be installed in between.
33. Work done to the indoor/outdoor unit after remove the front plate cover that secured by screws, must be carried out under the supervision of
authorized dealer and licensed installation contractor.
34. This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and telephone.
Otherwise, it may cause electrical shock in case equipment breakdown or insulation breakdown.
1. Do not install the air-to-water heatpump indoor unit and outdoor unit at place where leakage of flammable gas may occur. In case gas
leaks and accumulates at surrounding of the unit, it may cause fire.
2. Do not release refrigerant.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care of the
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, water piping) to prevent from insulation
failure (melt).
5. Do not touch the sharp aluminium fin, sharp parts may cause injury.
6. Do not apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause flooding and damage to
other properties.
7. Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the
furniture.
8. Select an installation location which is easy for maintenance.
9. 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.
 Strongly recommended to make permanent connection to a circuit breaker.
- Power Supply 1: Use approved 20A 4-poles circuit breaker with a minimum contact gap of 3.0mm.
- Power Supply 2: Use approved 15/16A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
(Only applicable for WH-SHF09F3E8) or
Use approved 20A 4-poles circuit breaker with a minimum contact gap of 3.0mm. (Only applicable for WH-SHF12F9E8)
10. Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fire.
11. After installation, check the water leakage condition in connection area during test run. If leakage occur, it will cause damage to other
properties
12. Installation work.
It may need two or more people to carry out the installation work. The weight of indoor/outdoor unit might cause injury if carried by one person.
