Procedure:
1). Connect the charge hose to the
charging cylinder, open the 2-way valve
and the 3-way valve.
Connect the charge hose which you
disconnected from the vacuum pump to
the valve at the bottom of the cylinder.
Make the cylinder bottom up to ensure the
liquid charge.
2). Purge the air from the charge hose.
Open the valve at the bottom of the
cylinder and press the check valve on the
charge set to purge the air (be careful of
the liquid refrigerant).
3) Put the charging cylinder onto the
electronic scale and record the weight.
4) Operate the air conditioner at the
cooling mode.
5) Open the valves (Low side) on the
charge set and charge the system with
liquid refrigerant.
6).When the electronic scale displays the
proper weight (refer to the table),
disconnect the charge hose from the 3-way
valve’s service port immediately and turn
off the air conditioner before disconnecting
the hose.
7). Mount the valve stem caps and the
service port
Use torque wrench to tighten the service
port cap to a torque of 18N.m.
Be sure to check for gas leakage.
