EVACUATION INSTRUCTIONS
Close the low pressure valve of the
manifold gauge and turn off the
vacuum.
Hold the pressure for 5 minutes, make
sure that the rebound of compound
gauge pointer does not exceed
0.005MPa.
Open the low pressure valve
counterclockwise for 1/4 turn with
hexagonal wrench to let a little
refrigerant fill in the system, and close
the low pressure valve after 5 seconds
and quickly remove the pressure hose.
Check all indoor and outdoor joints for
leakage with soapy water or leak
detector.
Fully open the low pressure valve and
high pressure valve of the outdoor unit
with hexagonal wrench.
Reinstall the protective caps of the
service port, low pressure valve and
high pressure valve of the outdoor unit.
Reinstall the valve cover.
A
WARNING
Air and foreign matter in the refrigerant
circuit can cause abnormal rises in
pressure, which can damage the air
conditioner, reduce its efficiency, 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 INSTRUCTIONS
Before using the manifold gauge and
vacuum pump, read their operation
manuals to familiarize yourself with how to
use them properly.
1. Use a spanner to remove the
protective caps from the service port,
low pressure valve and high pressure
valve of the outdoor unit.
2. Connect the pressure hose of
manifold gauge to the service port on
the outdoor unit low pressure valve.
3. Connect the charge hose from the
manifold gauge to the vacuum pump.
4. Open the low pressure valve of the
manifold gauge and close the high
pressure valve.
5. Turn on the vacuum pump to vacuum
the system.
6. The vacuum time should not be less
than 15 minutes, or make sure the
compound gauge indicates -0.1 MPa
(-76 cmHg)
