Haier 0010506358 Air Conditioner User Manual


 
1. If the supply cord is damaged, it must be replaced by the manufacturer or its
service agent or a similar qualied 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 betwee
n its two contacts should be not less
than 3mm.
Outdoor unit
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 ,
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.
Installation of Outdoor Unit
Half union
Flare nut
Torque wrench
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:
In case the elevation A is more

In case the pipe length B is
more than 7m, the refrigerant
should be charged, according
to 20 g/m.

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.
