1. Remove the Service port caps from both 3-way valves.
2. Connect the Manifold gauge set to the service port of Liquid
side 3-way valve.
3. Connect the Charging Cylinder to the Manifold gauge set
and open the valve of the Cylinder.
4. Open the low pressure side valve of the Manifold gauge for
approx. 10 seconds and then close.
5. Check a gas-leakage of the connecting portion of pipings.
6. Open the low pressure side valve of the Manifold gauge
again.
9.3.4. (a) EVACUATION OF THE EQUIPMENT (FOR EUROPE & OCEANIA DESTINATION)
WHEN INSTALLING AN AIR CONDITIONER, BE SURE TO EVACUATE THE AIR INSIDE THE INDOOR UNIT AND PIPES
in the following procedure.
1. Connect a charging hose with a push pin to the Low and High side of a charging set and the service port of the 3-way valve.
Be sure to connect the end of the charging hose with the push pin to the service port.
2. Connect the center hose of the charging set to a vacuum pump with check valve, or vacuum pump and vacuum pump adaptor.
3. Turn on the power switch of the vacuum pump and make sure that the needle in the gauge moves from 0 cmHg (0 MPa) to
-76 cmHg (-0.1 MPa). Then evacuate the air approximately ten minutes.
4. Close the valve at the charging set and turn off the vacuum pump. Make sure that the needle in the gauge does not move after
approximately five minutes.
Note: BE SURE TO TAKE THIS PROCEDURE IN ORDER TO AVOID REFRIGERANT GAS LEAKAGE.
5. Disconnect the charging hose from the vacuum pump and from the service port of the 3-way valve.
6. Tighten the service port caps of both of the 3-way valves at a torque of 18 N·m with a torque wrench.
7. Remove the caps of both of the 3-way valves. Position both of the valves to OPEN using a hexagonal wrench (4 mm).
8. Mount caps onto both of the 3-way valves.
Be sure to check for gas leakage.
CAUTION
If gauge needle does not move from 0 cmHg (0 MPa) to -76 cmHg (-0.1 MPa), in step 3 above take the following measure:
If the leak stops when the piping connections are tightened further, continue working from step 3.
If the leak does not stop when the connections are retightened, repair the location of leak.
Do not release refrigerant during piping work for installation and reinstallation. Take care of the liquid refrigerant, it may cause
frostbite.
