12.3.3 Evacuation of the Equipment
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.
o
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 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 for approximately 10 minutes.
4 Close the Low and High side valves of the charging set and turn off the vacuum pump. Make sure that the
needle in the gauge does not move after approximately 5 minutes.
Note: BE SURE TO FOLLOW THIS PROCEDURE IN ORDER TO REFRIGERANT GAS LEAKAGE.
5 Disconnect the charging hose from the vacuum pump and from the service of the 3-way valve.
6 Tighten the service port caps of the 3-way valve at a torque of 18 N•m with a torque wrench.
7 Remove the valve caps of both of the 3-way valve. Position both of the valves to “OPEN” using a hexagonal
wrench (4 mm).
8 Mount valve caps onto the both 3-way valve.
o
Be sure to check for gas leakage.
š
If gauge needle does not move from 0 cmHg (0 MPa) to -76 cmHg (-0.1 MPa), in the step e above take the following measure:
- If the leak stops when the piping connections are tightened further, continue working from step e .
- If the leak does not stop when the connections are retightened, repair location of leak.
- Do not release refrigerant during piping work for installation and reinstallation.
- Take care of the liquid refrigerant, it may cause frostbite.
12.3.4 Connect the cable to the Outdoor Unit
1 Remove the control board cover (metal) from the unit by loosening two screws.
2 Cable connection to the power supply through Isolating Devices (Disconnecting means).
o
Connect approved type polychloroprene sheathed power supply cord 3 x 1.5 mm
2
type designation
60245 IEC 57 or heavier cord to the terminal board, and connect the others end of the cord to Isolating
Devices (Disconnecting means).
3 Connection cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed 4 x
1.5 mm
2
flexible cord, type designation 60245 IEC 57 or heavier cord.
