Pump Down Operation

In order to protect the environment, be sure to pump down when relocating or disposing of the unit.

1) Remove the valve cap from liquid stop valve and gas stop valve.
2) Carry out forced cooling operation.
3) After 5 to 10 minutes, close the liquid stop valve with a hexagonal wrench.
4) After 2 to 3 minutes, close the gas stop valve and stop forced cooling operation.

Forced cooling operation

Using the indoor unit ON/OFF switch

Press the indoor unit ON/OFF switch for at least 5 seconds. (Operation will start.)

• Forced cooling operation will stop automatically after about 15 minutes. 

 

To stop the operation, press the indoor unit ON/OFF switch.

Using the indoor unit’s remote controller

1) Press “MODE” button and select the cooling mode. 
2) Press “ON/OFF” button to turn on the system.
3) Press both the “TEMP” button and “MODE” button at the same time. 
4) Press “MODE” button twice. ( 

 will be displayed and the unit will 

enter forced cooling operation.) 

• Forced cooling operation will stop automatically after about 

30 minutes. To stop operation, press “ON/OFF” button.

Using the outdoor unit forced cooling operation switch 

Forced cooling operation can be performed when the outdoor unit forced 
cooling operation switch is pressed within 3 minutes after power is 
supplied.

 

Push on the area marked “

” (SW1) with a screwdriver and the 

operation will start.

• Forced cooling operation will stop automatically after approximately 

15 minutes.

 

To stop the operation, press the switch (SW1).

Wiring

 WARNING

• Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, electrical 

shock, or fire.

• 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 fire.

• Be sure to install an earth leak detector. (One that can handle higher harmonics.)

 

(This unit uses an inverter, which means that an earth leak detector capable of handling higher harmonics must be used, 
in order to prevent malfunctioning of the earth leak detector itself.)

• Use an all-pole disconnection type breaker with at least 3mm between the contact point gaps.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.

• Equipment complying with EN61000-3-12

(1)

• Do not turn ON the power supply until all work is completed.

1) Strip the insulation from the wire (20mm).
2) Connect the connection wires between the 

indoor and outdoor units so that the terminal 
numbers match. Tighten the terminal screws 
securely. We recommend a flathead 
screwdriver be used to tighten the screws.
