1. Connect a charging hose with a push pin to the Low 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 Low side valve of 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 FOLLOW 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 the 3-way valve at a torque of 18 N•m with a torque wrench.
7. Remove the valve caps of both of the 2-way valve and 3-way valve. Position both of the valves to "OPEN" using a hexagonal
wrench (4 mm).
8. Mount valve caps onto the 2-way valve and the 3-way valve.
• 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.
9.2.4. OUTDOOR UNIT ELECTRICAL WIRING
1. Remove Top panel.
2. Remove Control Board Cover (Metal and Resin).
3. Remove Plugs.
4. Fix the conduit connectors to the conduit holes with lock-
nuts, then secure them against the side panel.
5. Connecting wire between indoor unit and outdoor unit
should be UL listed or CSA approved 4 x AWG16 wire.
6. Secure the wire onto the control board with the holder
(clamper).
7. Cable connection to the power supply (208/230V 60Hz)
through circuit breaker.
• Connect the UL listed or CSA approved power wires
(AWG14) heavier cord to the terminal board, and con-
nect the other end of the wires to circuit breaker.
8. After completing wiring connections, reattach the control
board cover (Metal and Resin) and the top panel to the
original position with the screws.
