7). Replace the valve stems nuts and the service port cap that were previously removed.

Be sure to use a torque wrench to tighten the service port cap to a torque of 18N·m.

Be sure to check for gas leakage using soap water.

3. Adding the refrigerant if the pipe length >(5m)16.5ft

Electronic scale

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. Because refrigerant is R410A, turn the cylinder upside down, ensuring the bottom is upward, to create a 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 in the cooling mode.

5)Open the valves (Low side) on the charge set and charge the system with the proper amount (refer to table) liquid refrigerant.
