Vacuum Pumping Method:
(R410A refrigerant evacuation must use the Vacuum Pumping Method)

hose, manifold valve, and vacuum
pump.
3. Fully open the “Handle Lo” of the
manifold valve and apply the
vacuum for at least 15 minutes.
Check that the compound vacuum

outdoor connections are free of air
leakage.
