Add 0.22oz/ft (20g/m) of
Refrigerant for piping that exceeds
50ft (15m) up to 66ft (20m)
* Caution during addition of refrigerant Max. amount of
additional refrigerant is 0.22 lbs (100g).
Charge the refrigerant accurately. Overcharging may
cause serious trouble to the compressor.
* Minimum refrigerant pipe is 6.6ft (2m).
Using pipe shorter than that may cause a malfunction of
the compressor or other components.
• The power supply shall be connected to the outdoor unit
by 3 wires.
• The connecting cable between the indoor unit and outdoor
unit is 4 wires.
This cable provides the power for the indoor unit and the
communication signal between the outdoor unit and indoor
unit.
• Consult local building codes, NEC (National Electrical Code)
or CEC (Canadian Electrical Code) for special requirements.
