10. Air Evacuation
Preparations and Precautions
Air and foreign matter in the refrigerant circuit can cause
abnormal rises in pressure, which can damage the air
conditioner, reduce its efciency, and cause injury. Use
a vacuum pump and manifold gauge to evacuate the
refrigerant circuit, removing any non-condensable gas
and moisture from the system
Evacuation should be performed upon initial installation
and when unit is relocated.
BEFORE PERFORMING EVACUATION
5Check to make sure the connective pipes between
the indoor and outdoor units are connected properly.
5Check to make sure all wiring is connected properly.
Evacuation Instructions
1. Connect the charge hose of the manifold gauge to
service port on the outdoor unit's low pressure valve.
2. Connect another charge hose from the manifold
gauge to the vacuum pump.
3. Open the Low Pressure side of the manifold gauge.
Keep the High Pressure side closed.
4. Turn on the vacuum pump to evacuate the system.
5. Run the vacuum for at least 15 minutes, or until
the Compound Meter reads -76cmHG (-105Pa) del
sistema.
6. Close the Low Pressure side of the manifold gauge,
and turn off the vacuum pump.
7. Wait for 5 minutes, then check that there has been no
change in system pressure.
8. If there is a change in system pressure, refer to Gas
Leak Check section for information on how to check
for leaks. If there is no change in system pressure.
unscrew the cap from the packed valve (high pressure
valve).
9. Insert hexagonal wrench into the packed valve (high
pressure valve) and open the valve by turning the
wrench in a 1/4 counterclockwise turn. Listen for
gas to exit the system, then close the valve after 5
seconds.
10. Watch the Pressure Gauge for one minute to make
sure that there is no change in pressure. The Pressure
Gauge should read slightly higher than atmospheric
pressure.
11. Remove the charge hose from the service port.Utilice
una llave hexagonal para abrir al máximo la válvula
de alta presión y la válvula de baja presión.
12. Using hexagonal wrench, fully open both the high
pressure and low pressure valves.
13. Tighten valve caps on all three valves (service port,
high pressure, low pressure) by hand. You may
tighten it further using a torque wrench if needed..
OPEN VALVE STEMS GENTLY
When opening valve stems, turn the hexagonal wrench
until it hits against the stopper. Do not try to force the
valve to open further.
