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 side of a charging set and the service port of the 3-way
valve.
2 Connect the micron gauge between vacuum pump and service port of outdoor units.
3 Turn on the power switch of the vacuum pump and make sure that connect digital micron gauge and to pull
down to a value of 500 microns.
4 To make sure micron gauge a value 500 microns and close the low side valve of the charging set and turn off
the vacuum pump.
5 Disconnect the vacuum pump house from the service port of the 3-way valve.
6 Tighten the service port caps of the 3-way valve at a torque of 13.3 Ibf.ft (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 (5/32" (4 mm)).
8 Mount valve caps onto the 2-way valve and the 3-way valve.
o
Be sure to check for gas leakage.
If micron gauge value does not descend 500 microns, take the following measures:
-
If the leak stops when the piping connections are tightened further, continue working from step
.
-
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.
-
Be careful with the liquid refrigerant, it may cause frostbite.
12.3.4 Connect the Cable to the Outdoor Unit
1 Remove control board cover (Resin and
Metal).
2 Remove particular plate.
3 Remove
plugs.
4 Fix the conduit connectors to the knockout
holes with lock-nuts, then secure them against
the side panel.
5 All wires pass through conduits & particular
plate’s opening hole.
6 Connecting wire between indoor unit and
outdoor unit should be UL listed or CSA
approved 4 conductor wires minimum AWG16
in accordance with local electric codes.
7 Wire connection to the power supply
(208/230V 60Hz) through circuit breaker.
o
Connect the UL listed or CSA approved
wires minimum AWG12 to the terminal
board, and connect the other end of the
wires to ELCB/ GFCI.
8 Connect the power supply cord and
connecting wire between indoor unit and
outdoor unit according to the diagram below.
9 Secure the wire onto the control board with
the holder (clamper).
10 After completing wiring connections, reattach
the particular plate and control board cover
(metal and resin) to the original position with
the screws.
