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. (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.

 

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 of “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 around 30 minutes.  

To stop the operaion, 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 
around 3 minutes after power is supplied.
Press the switch (SW1). (The operation will start.)

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

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 a ground fault circuit interrupter breaker. (One that can handle higher harmonics.)  

(This unit uses an inverter, which means that it must be used a ground fault circuit interrupter breaker capable handling 
harmonics in order to prevent malfunctioning of the ground fault circuit interrupter breaker itself.)

• Use an all-pole disconnection type breaker with at least 1/8 inch (3mm) between the contact point gaps.
• When carrying out wiring connection, 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 fire.

• Do not turn on the safety breaker until all work is completed.

1)  Strip the insulation from the wire (3/4inch (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.
