Install according to
Drawing for the installation of indoor and outdoor units
To bend a pipe, give the roundness as large as possible not to crush the pipe ,
ƽ
and the bending radius should be 30 to 40 mm or longer.
Connecting the pipe of gas side first makes working easier.
ƽ
The connection pipe is specialized for R410A.
ƽ
Use the same method on indoor unit. Loosen the screws on
ƽ
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.
ƽ
If wiring is not correct, proper operation can not be carried out and controller

CAUTION
Be careful that matters, such as wastes of sands, etc. shall not enter the pipe.
The standard pipe length is 5m. If it is over 7m, the function of the unit will be
affected. If the pipe has to be lengthened, the refrigerant should be charged,
according to 20 g/m. But the charge of refrigerant must 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
Spanner
Forced fastening without careful centering may
damage the threads and cause a leakage of gas.
Max.Elevation: Amax=10m
●
In case the elevation A is more
●
than 5m, oil trap shoud be
installed every 5~7m
Max. Length: Bmax=15m
●
In case the pipe length B is
●
more than 7m, the refrigerant
should be charged, according
to 20 g/m.
