Vacuum and Leak Test:
o
Attach gauges to the service ports.
o
Outdoor unit is factory pre-charged; make sure shut off valves are closed
(as received) during pressure testing and evacuating.
o
Once the gauges are attached pressurize the line set using Nitrogen at
300 PSIG and check for leaks.
o
Next, evacuate the unit down to a minimum of 200 Microns for 30 minutes.
It is essential that a deep vacuum be pulled on the system to remove all
traces of moisture.
o
At this point in the installation it is a good idea to connect the electrical
power while the vacuum is running. See next section.
o
Close gauge valves and shut down the vacuum pump.
Connection to suction line Connection to vacuum pump
Electrical connections:
o
Electrical wiring should be done in accordance with National Electrical
Code (NEC) and local state/city building codes.
o
Ensure that the proper size breaker is used for the rating plate amperage.
o
Each system installed must have a dedicated branch circuit with an
individual breaker/fuse.
o
A local disconnect should be installed adjacent to the outdoor unit.
o
The outdoor unit provides power for the Indoor unit therefore, no
disconnect is required between the outdoor and indoor units.
o
On the indoor unit, connect the electrical wires to the terminal strip and
close cover (remember what color goes to which terminal).
o
On the outdoor unit remove RHS knockout on the terminal access panel
for whip/wiring connection.
