will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
Do not add or replace refrigerant other than specifi ed type. It may cause product damage, burst and injury etc.
•
For R410A model, use piping, fl are nut and tools which is specifi ed for R410A refrigerant. Using of existing (R22) piping, fl are nut and tools may cause abnormally high
pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.
•
Thickness for copper pipes used with R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
•
It is desirable that the amount of residual oil less than 40 mg/10 m.
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical shock or fi re.
Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fi re.
Use the attached accessories parts and specifi ed parts for installation. Otherwise, it will cause the set to fall, water leakage, fi re or electrical shock.
Install at a strong and fi rm 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.
For electrical work, follow the local national wiring standard, regulation and this installation instruction. An independent circuit and single outlet must be used. If electrical
circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fi re.
Do not use joint cable for indoor / outdoor connection cable. Use the specifi ed indoor/outdoor connection cable, refer to instruction 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 fi xing is not
perfect, it will cause heat up or fi re at the connection.
Wire routing must be properly arranged so that control board cover is fi xed properly. If control board cover is not fi xed perfectly, it will cause fi re or electrical shock.
This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD). Otherwise, it may cause electrical
shock and fi re in case of equipment breakdown or insulation breakdown.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fi xing 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 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 fl are nut with torque wrench according to specifi ed method. If the fl are nut is over-tightened, after a long period, the fl are may break and cause refrigerant gas
leakage.
After completion of installation, confi rm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts with fi re.
Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fi re.
