Electrical Connections
Install the outdoor unit on a hard and even place that can support its weight.
- If the place cannot support its weight, the outdoor unit may fall down and it may
cause injury.
The electric work must be done by service agent or similarly qualified persons according to
national wiring regulations and use only rated cable.
- If the capacity of the power cable is insufficient or electric work is not properly completed,
electric shock or fire may occur.
Make sure there is no leakage after installation.
- Toxic gas may generate when refrigerant gas contacts with fire.
Install the outdoor unit correctly according to the installation manual.
- An incorrect installation may cause a water leakage, electric shock or fire and so on.
The installation must be done by the manufacturer or its service agent or a similar qualified
person in order to avoid a hazard.
- Installation by an unqualified person may cause a water leakage, electric shock or fire
and so on.
The unit must be plugged into an independent circuit if applicable or connect the power
cable to the auxiliary circuit breaker. An all pole disconnection from the power supply must
be incorporated in the fixed wiring with a contact opening of >3mm.
Switch off the main circuit breaker and the branch circuit breaker before electric work.
Perform earthing work 3 without fail. An earthing resistance should be under 100Ω.
The protective earthing resistance can be applied in case of using ELCB (Earth Leakage
Circuit Breaker). When using an ELCB that has a tolerance limit as 100mA per second,
the protective earthing resistance is 250Ω in an electrical danger zone, else under 500Ω.
The input voltage of the indoor and outdoor unit should be within ±10% of the rated one.
For details of wiring, refer to the circuit diagram attached onto the outdoor unit.
The circuit diagram for wiring shows only the concept.
Do not connect the heater to the outdoor unit and do not install remodeled duct as you
please.
- The capacity of the Air to water heat pump may reduce and electric shock or fire may occur.
Install the power cable and communication cable of the indoor and outdoor unit at least
1.5m away from electric appliances.
- Noise may hear depending on the electric wave though the cables are installed away from
electric appliances.
Install the indoor unit away from lighting apparatus using the ballast.
- If you use the wireless Remote controller, it may not operate normally.
