WARNING
16.
For refrigeration system work, install according to this installation instructions strictly. If installation is defective, it will cause
water leakage, electrical shock or fire.
17.
Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire
or electrical shock.
18.
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 done, the set will drop and cause injury.
19.
For electrical work, follow the national regulation, legislation and this installation instructions. An independent circuit and single
outlet must be used. If electrical circuit capacity is not enough or defect found in the electrical work, it will cause electrical shock
or fire.
20.
Do not use joint cable for indoor/outdoor connection cable. Use the specified indoor/outdoor connection cable, refer to
instruction
5
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.
21.
Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly,
it will cause fire or electrical shock.
22.
This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device
(RCD), 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.
23.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing
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.
24.
During pump down operation, stop the compressor before removing the refrigeration piping. Removal of refrigeration piping
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.
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 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.
29.
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 of equipment breakdown or insulation breakdown.
