the outdoor unit.
PROCEDURE USING GAUGE MANIFOLD
dure)
(1) Connect the gauge manifold hose to the service port of the 3-way
valve.
(2) Run the air conditioner at the forced cooling operation.
(3) After 5-10 minutes, close the 2-way valve.
(4) Close the 3-way valve when the compound gauge reading becomes
almost 0 MPa(0 cmHg).
(5) Stop the forced cooling operation.
(6) Disconnect the gauge manifold hose from the service port.
(7) Disconnect both refrigerant pipes.
PROCEDURE WITHOUT USING GAUGE MANIFOLD
(1) Run the air conditioner at the forced cooling operation.
(2) After 5-10 minutes, fully close the 2-way valve by turning the hexagon
