refrigerant leakage, fire or electrical shock.
7. Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not properly done,
the set will drop and cause injury.
8. Do not install outdoor unit near handrail of veranda. When installing outdoor unit at veranda of high rise building, child may climb up
to outdoor unit and cross over the handrail and causing accident.
9. For electrical work, follow the local national wiring standard, regulation and the 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 fire.
10. 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 electric shock in case equipment breakdown or insulation breakdown.
11. Do not use joint cable for indoor/outdoor connection cable. Use specified indoor/outdoor connection cable, refer to Installation Instructions
CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor/outdoor connection. Clamp the cable so that no external force
will be acted on the terminal. If connection or fixing is not perfect, it will cause heat up or fire at the connection.
12. When install or relocate Air to Water Heatpump indoor/outdoor unit, do not let any substance other than the specified refrigerant, eg. air etc.
mix into refrigerant cycle (piping). Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
13. This is a R410A model, when connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same may cause
abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. Use only R410A refrigerant.
Thickness of 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 is less than 40 mg/10 m.
14. During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fixing refrigeration piping
and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
15. During pump down operation, stop the compressor before remove the refrigeration piping. Removal of refrigeration piping while compressor is
operating and valves are opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion,
injury etc.
16. After completion of the installation servicing confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant
contacts with fire.
17. Ventilate the room if there is refrigerant gas leakage during operation. Extinguish all fire sources if present. It may cause toxic gas when the
refrigerant contacts with fire.
18. Only use the supplied or specified installation parts, else, it may cause unit vibrate loose, water/refrigerant leakage, electrical shock or fire.
