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- min. If the scale-moves back in spite of
tightening, make flaring work again, the return to the beginning of 3 .

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.

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 flaring work again and vacuumize, fill up prescribed
refrigerant from the gas cylinder.

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.

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 conditio-
ner according to the amount marked on the name plate.
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.
Power Source Installation
The power source must be exclusively used for air conditioner. (Over I0A)
In the case of installing an air conditioner in a moist place, please install an ea-
rth leakage breaker.
For installation in other places, use a circuit breaker as far as possible.
Cutting and Flaring Work of Piping
Pipe cutting is carried out with a pipe cutter and burs must be removed.
After inserting the flare nut, flaring work is carried out.
