Panasonic WH-ADF0309J3E5CM Service Manual page 5

Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire or
16.
electrical shock.
Install at a strong and firm location which is able to withstand weight of the set. If the strength is not enough or installation is not
17.
properly done, the set will drop and cause injury.
For electrical work, follow the national regulation, legislation and this installation instructions. An independent circuit and single outlet
18.
must be used. If electrical circuit capacity is not enough or defect found in the electrical work, it will cause electrical shock or fire.
Do not use joint cable for indoor / outdoor connection cable. Use the specified indoor/outdoor connection cable, refer to instruction
19. ⑤ CONNECT THE CABLE TO THE OUTDOOR UNIT and connect tightly for indoor/outdoor connection. Clamp the cable so that no
external force will have impact on the terminal. If connection or fixing is not perfect, it will cause heat up or fire at the connection.
Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will
20.
cause fire or electrical shock.
This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device
21. (RCD), with sensitivity of 30 mA at 0.1 sec or less. Otherwise, it may cause electrical shock and fire in case of equipment breakdown
or insulation breakdown.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing
22. refrigeration piping and valves at opened position 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 removing the refrigeration piping. Removal of refrigeration piping while
23. compressor is operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigeration 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
24.
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
25.
contacts with fire.
The following checks shall be applied to installations using flammable refrigerants. Appliance shall be installed, operated and stored in
26. a room with a floor area larger than [Amin] m
As for [Amin], see the section "INDOOR FLOOR AREA REQUIREMENT".
27. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fire.
28. Be aware that refrigerants may not contain an odour.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and
29. telephone.
Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown.
Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the
1.
unit, it may cause fire.
2. Prevent liquid or vapor from entering sumps or sewers since vapor is heavier than air and may form suffocating atmospheres.
Do not release refrigerant during piping work for installation, re-installation and during repairing refrigeration parts. Take care of the
3.
liquid refrigerant, it may cause frostbite.
4. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
5. Do not touch the sharp aluminium fin, sharp parts may cause injury.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and
6.
damage the furniture.
Select an installation location which is easy for maintenance.
7. Incorrect installation, service or repair of this air conditioner may increase the risk of rupture and this may result in loss damage
or injury and/or property.
Installation work.
8.
It may need two people to carry out the installation work.
9. Keep any required ventilation openings clear of obstruction.
