1)Turn off the power supply, remove the panels and close the water supply line shut-off valve.

2)Recover the refrigerant and store it in an approved container.

3)Disconnect the capillary tube using brazing equipment.

4)Disconnect the flare-connections of the valve.

5)Remove the screws and the valve from the bracket.

6)Install the new valve, and braze the capillary tube.

7)Install the new drier.

8)Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.

9)Connect the flare-connections.

10)Evacuate the system, and charge it with refrigerant. See the nameplate for the required refrigerant charge and type.

11)Open the water supply line shut-off valve, and turn on the power supply.

12)Check for water leaks.
