Panasonic CS-Z20XKEW Service Manual page 6

Engage authorized dealer or specialist for installation and servicing. If installation or servicing done by the user is incorrect, it will cause
12.
water leakage, electrical shock or fire.
For refrigeration system work, install according to this installation instructions strictly. If installation is defective, it will cause water leakage,
13.
electrical shock or fire.
Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water leakage,
14.
fire or 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 properly
15.
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 must
16.
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
17. CONNECT THE CABLE TO THE INDOOR 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
18.
cause fire or electrical shock.
This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD),
19. with sensitivity of 30mA 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
20. 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
21. 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 may
22.
break and cause refrigerant gas leakage.
After completion of installation or service, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant
23.
contacts with fire.
24. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fire.
25. 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 telephone.
26.
Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown.
27. Do not modify the machine, part, material during repairing service.
28. If wiring unit is supplied as repairing part, do not repair or connect the wire even only partial wire break. Exchange the whole wiring unit.
29. Do not wrench the fasten terminal. Pull it out or insert it straightly.
30. Must not use other parts except original parts describe in catalog and manual.
Do not install the unit in a place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of
1.
the 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, servicing, re-installation and during repairing refrigeration parts. Take
3.
care of the 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, servicing, 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.
Power supply connection to the room air conditioner.
Use power supply cord 3 x 1.5 mm
Connect the power supply cord of the air conditioner to the mains using one of the following method.
Power supply point should be in easily accessible place for power disconnection in case of emergency.
In some countries, permanent connection of this air conditioner to the power supply is prohibited.
8.
1) Power supply connection to the receptacle using power plug.
Use an approved 15/16A (3/4 ~ 1.75HP), 16A (2.0HP), 20A (2.5HP) power plug with earth pin for the connection to the socket.
2) Power supply connection to a circuit breaker for the permanent connection.
Use an approved 16A (3/4 ~ 2.0HP), 20A (2.5HP) circuit breaker for the permanent connection. It must be a double pole switch with a
minimum 3.0 mm contact gap.
2 2
(3/4 ~ 1.75HP), 3 x 2.5 mm
CAUTION
(2.0 ~ 2.5HP) type designation 60245 IEC 57 or heavier cord.
