1. If the supply cord is damaged, it must be replaced by the manufacturer or its
service agent or a similar quali
ed person. The type of connecting wire is
H05RN-F
or H07RN-F.
2. If the fuse on PC board is broken please change it with the
type of
T. 3.15A/250V.
3. The wiring method should be in line with the local wiring standard.
4. After installation, the power plug should be easily reached.
5. A breaker should be incorporated into
xed wiring. The breaker should be
all-pole
switch and the distance between its two contacts should be not less
than 3mm.

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.
The connection pipe is specialized for R410A.
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.

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

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