Air Purging - Frigidaire FRS09PYS1 Installation Manual

Caution
After the confirmation of the above conditions, prepare the wiring as follows:
1. Never fail to have an individual power circuit specifically for the air
conditioner. As for the method of wiring, be guided by the circuit diagram
posted on the inside of control cover.
2. The screws which fasten the wiring in the casing of electrical fittings are
liable to come loose from vibrations to which the unit is subjected during
the course of transportation. Check them and make sure that they are all
tightly fastened. (If they are loose, it could cause burn-out of the wires.)
3. Specification of power source.
4. Confirm that electrical capacity is sufficient.
5. See to that the starting voltage is maintained at more than 90 percent of
the rated voltage marked on the name plate.
6. Confirm that the cable thickness is as specified in the power source
specification.
7. Always install an earth leakage circuit breaker in a wet or moist area.
8. The following would be caused by voltage drop: vibration of a magnetic
switch, which will damage the contact point, fuse breaking, disturbance of
the normal function of the overload protector.
9. The means for disconnection from a power supply shall be incorporated
in the fixed wiring and have an air gap contact separation of at least
in each active (phase) conductors.

Air purging

Air and moisture in the refrigeration system have undesirable effects as indicated
below:
1. Pressure in the system rises.
2. Operating current rises.
3. Cooling or heating(only for
models with heating function)
efficiency drops.
4. Moisture in the refrigerant circuit
may freeze and block capillary
tubing.

5. Water may lead to corrosion of
parts in the refrigeration system.
Therefore, the indoor unit and tubing
between the indoor and outdoor unit
must apply leakage test and be evacuated
to remove any noncondensables and
moisture from the system.
