Haier HSU-22HRA03/R2 On Drainage, Power Source Installation, Cutting and Flaring Work of Piping

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

6.Detach the charge hose from the service port, open 2-way valve and 3-way. Turn 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.

●Please pour water in the drain pan of the indoor unit, and confirm that drainage is carried out surely to outdoor.

●In case that the attached drain hose is in a room, please apply heat insulation to it without fail.

CAUTION

●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.

1 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.

2Cutting 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.
