6.6 Re-installation of the Indoor Unit
6.6.1. Collecting the Refrigerant into the Outdoor Unit
Procedure:
1.
Confirm that both the 2-way and 3-way valves are set to the opened position. Remove the valve
stem caps and confirm that the valve stems are in the opened position. Be sure to use a hexagonal
wrench to operate the valve stems.
2.
Connect the charge hose with the push pin of Handle Lo to the 3-way valves gas service port.
3.
Air purging of the charge hose. Open the Handle Lo valve of the manifold valve slightly to purge
air from the charge hose for 5 seconds and then close it quickly.
4.
Set the 2-way valve to the close position.
5.
Operate the air conditioner at the cooling cycle and stop it when the gauge indicates 14.5 psi (0.1
MPa).
6.
Set the 3-way valve to the closed position immediately. Do this quickly so that the gauge ends up
indicating 43.5 psi (0.3 MPa) to 72.5 psi (0.5 MPa). Disconnect the charge set, and tighten the 2-
way and 3-
way valve’s stem nuts. Use a torque wrench to tighten the 3
-way valves service port
cap to a torque of 13.3ft·lb (18N·m). Be sure to check for gas leakage.
