To bend a pipe, give the roundness as large as possible not to crush the pipe ,
and the bending radius should be 30 to 40
mm or longer.
Connecting the pipe of gas side
rst makes working easier.
TheconnectionpipeisspecializedforR410A.
Use the same method on indoor unit. Loosen the screws on
terminal block and
insert the plugs fully into terminal block, then tighten the screws.
Insert the cable according to terminal number in the same manner as the indoor
unit.
If wiring is not correct, proper operation can not be carried out and controller
may be damaged.
Fix the cable with a clamp.

The standard pipe length is 5m. If it is over 5m, the function of the unit will be
affected. If the pipe has to be lengthened, the refrigerant should be charge
d,
accordingto20g/m.Butthechargeofrefrigerantmust
be conducted by profes-
sional air conditioner engineer. Before adding additional refrigerant, perform air
purging from the refrigerant pipes and indoor unit using a vacuum pump,then

Forced fastening without careful centering may
damage the threads and cause a leakage of gas.
