Panasonic CS-HZ25UKE Service Manual page 4

Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly,
18.
it will cause fire or electrical shock.
This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device
19. (RCD), with sensitivity of 30mA at 0.1sec 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
21. while 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
22.
flare 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
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
26.
telephone. Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown.
Do not install the unit in a place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding
1.
of 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, re-installation and during repairing refrigeration parts. Take care of
3.
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 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. Incorrect installation, service or repair of this air conditioner may
7.
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 × 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 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 circuit breaker for the permanent connection. It must be a double pole switch with a minimum 3.0 mm
contact gap.
Installation work.
9.
It may need two people to carry out the installation work.
10. Keep any required ventilation openings clear of obstruction.
