Fixed the unit
First, the metal mounting bracket is fixed on the wall, the expansion bolts of the
12mm. Then put the outdoor machine flat and fixed on the stand.
Installation of drainage elbow
If you use a drainage elbow, refer to the following image to install. Where the

When the pipe is lengthened, the after-sales installer should be equipped with a
professional evacuation pump to evacuate the air inside the pipe..
The R32 refrigerant injected into the new factory air conditioner is the net gas
injection amount. It is forbidden to use the internal row method for emptying.
To bend a pipe, give the roundness as large as possible not to crush the pipe,
and the bending radius should be 30 to 40mm or longer.
Connecting the pipe of gas side first makes working easier.
The connection pipe is specialized for R32.

Connection
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.
Attaching Drain-Elbow

Purging Method:To use vacuum pump
1.
Detach the service port's cap of
3-way valve, the valve rod's cap for 2-way valve
and 3-way's, connect the service port into the projection of charge hose (Iow)
for gaugemanifold. Then connect the projection of charge hose (center) for gau-
gemanifold into vacuum pump.
2.
gaugemanifold, operate vacuum pump. If the scale-

3.
Vacuumize for over 15min.And check the level gauge which should read -0.1MPa
(76 cm Hg) at Iow pressure side. After the completion of vacuumizing, close the
handle 'Lo' in gaugemanifold and stop the operation of the vacuum pump. Check
condition of the scale and hold it for 1-2min. If the scale-moves back in spite of
tightening, make aring work again, the return to the beginning of 3 .
4.
Open the valve rod for the 2-way valve to an angle of
After 6 seconds, close the 2-way valve and make the inspection of gas leakage.
5.
No gas leakage?
In case of gas leakage, tighten parts of pipe connection. If
leakage stops, then proceed 6. steps
If it does not stop gas leakage, discharge whole refrigerants from the service
port. After aring work again and vacuumize, ll up prescribed
refrigerant from the gas cylinder.
6.
from the service port, open 2-way valve and 3-way. Turn
Detach the charge hose
the valve rod anticlockwiseuntil hitting lightly.
7.
To prevent the gas leakage, turn the service port's cap, the valve rod's cap for 2-way
valve and 3-way's a little more than the point where the torque increases suddenly.
8.
After attaching the each caps, check the gas leakage around the caps.
