2.Connection of pipes
Install according to
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 first makes working easier.
The connection pipe is specialized for R410A.
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 professional air conditioner engineer . Before adding additional refrigerant,
perform air purging from the refrigerant pipes and indoor unit using a vacuum pump,then charge
additional refrigerant.
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.
If wiring is not correct, proper operation can not be carried out and controller may be damaged.
If the drain-elbow is used, please attach it as
figure. (Note: Only for heat pump unit.)
Drawing for the installation of indoor and outdoor units
Insert the cable according to terminal number in the same manner as the indoor unit.
Fix the cable with a clamp.

5.Purging Method:To use vacuum pump
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
(low) for gaugemanifold. Then connect the projection
of charge hose (center) for gaugemanifold into
vacuum pump. Tube(for R410A)
Open the handle at low in gaugemanifold, operate
vacuum pump. If the scale-moves of gause (low)
reach vacuum condition in a moment, check again.
Vacuumize for over 15min. And check the level gauge
which should read -0.1 MPa (-76 cm Hg) at low
pressure side. After the completion of vacuumizing,
close the handle 'Lo' in gaugemanifold and stop the
operation of the vacuum pump.
Check the condition of the scale and hold it for 1-2min.
If the scale-moves back in spite of tightening, make
flaring work again, the return to the beginning of .
Open the valve rod for the 2-way valve to an angle of
anticlockwise 90 degrees.
After 6 seconds, close the 2-way valve and make
the inspection of gas leakage.
No gas leakage?
In case of gas leakage, tighten
parts of pipe connection. If
leakage stops, then proceed
steps.
Detach the charge hose from the service port, open
2-way valve and 3-way. Turn the valve rod anticlockwise
until hitting lightly.
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.
After attaching the each caps, check the gas leakage
around the caps.
CAUTION:
1.If the refrigerant of the air conditioner leaks, it is necessary to
discharge all the refrigerant. Vacuumize first, then charge the liquid
refrigerant into air conditioner according to the amount marked on
the name plate.
2.Please do not let other cooling medium, except specified one (R410A),
or air enter into the cooling circulation system. Otherwise, there will be
abnormal high pressure in the system to make it crack and lead to
personal injuries.
If it does not stop gas leakage, discharge
whole refrigerants from the service port.
After flaring work again and vacuumize,
fill up prescribed refrigerant from the gas
