WIRING
WARNING
Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electric shock,
or re.
Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc.,
from the terminal block.) Doing so may cause electric shock or re.
Be sure to install a earth leakage circuit breaker. (One that can handle higher harmonics.)
(This unit uses an inverter. Therefore, a earth leakage circuit breaker capable of handling higher harmonics must be
used in order to prevent the earth leakage circuit breaker malfunctioning.)
Use an all-pole disconnection type circuit breaker with at least 3mm (1/8 inch) between the contact point gaps.
When carrying out wiring, take care not to pull at the conduit.
Do not connect the power wire to the indoor unit. Doing so may cause electric shock or re.
Do not turn on the circuit breaker until all work is completed.
1) Strip the insulation from the wire (20mm).
2) Connect the inter-unit wires between the indoor and outdoor units so that the terminal numbers match. Tighten the
terminal screws securely. It is recommended that a athead screwdriver be used to tighten the screws.
The screws are packed with the terminal block.

Forced cooling operation
Using the indoor unit ON/OFF switch
Press the indoor unit ON/OFF switch for at least 5 seconds. (The operation will start.)
Forced cooling operation will stop automatically after around 15 minutes.
To stop the operation, press the indoor unit ON/OFF switch.
After closing the liquid stop valve, close the gas stop valve within 3 minutes, then stop the forced cooling operation.
CAUTION
To pump down
DANGER: RISK OF EXPLOSION
Pump down - Refrigerant leakage. If you want to pump down the system, and there is a leakage in the refrigerant circuit:
Do NOT use the unit's automatic pump down function, with which you can collect all refrigerant from the system into the
outdoor unit. Possible consequence: Self-combustion and explosion of the compressor because of air going into the
operating compressor.
Use a separate recovery system so that the unit's compressor does NOT have to operate.
NOTICE
During pump down operation, stop the compressor before removing the refrigerant piping. If the compressor is still running
and the stop valve is open during pump down, air will be sucked into the system. Compressor breakdown or damage to the
system can result due to abnormal pressure in the refrigerant cycle.
