  5.7 Refrigerant Recovery Methods   

When the unit must be moved and outdoor

’s refrigerant have to be recovered, please   

follow these steps to implement the operation. 
1) Please close the gas line stop valve, liquid line stop valve and the mani-fold 

gauge. 

2) Please turn on the power source. 
3) Setting to ON of outdoor unit electrical board DSW1-1, please implement cooling 

operation, then closed the liquid line stop valve, and refrigerant recovered 
operation will be started. 

4) When the low-pressure (gas line stop valve) side of the pressure display 

-0.01MPa (-100mmHg), please action rapidly according the following 

instructions

：

 

1.Please close the gas line stop valve. 
2. Setting to OFF of outdoor unit electrical board DSW1-1. (Unit stop).   
5) Please turn off the power source. 

 

 

 

 

Caution

 

●Please do not let low-pressure gauge to measure the pressure is lower than-0.01MPa. 
●When the refrigerant recovered operation, the low pressure is less than-0.01MPa, will result in compressor 

failure. 

 

 

6. Electrical Wiring 

 

  6.1 Wiring Capacity  

 

1) The indoor and outdoor unit transmission   

cable of the connection is a non-polar. 

 

 
 
 

 

2) The type of earth leakage breaker required for the " high-speed type " (active time less than 0.1 sec.), when to buy, please pay 

special attention. 

3) Around the unit installed over current breaker, the manual switch and earth leakage breaker (ELB) should be separated, but need set 

up it together. 

4) Outdoor unit power supply specification for the 3
