6.REMOVAL AND REPLACEMENT OF HOT GAS VALVE AND LINE VALVE

IMPORTANT

Always use a copper tube of the same diameter and length when replacing the hot gas lines; otherwise the performance may be reduced.

IMPORTANT

Always install a new Drier every time the sealed refrigeration system is opened. Do not replace the Drier until after all other repair or replacement has been made.

1)Turn off the power supply.

2)Remove the panels.

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

4)Remove the screw and the Solenoid.

5)Disconnect the Hot Gas Valve or Line Valve using brazing equipment.

6)Install the new valve.

CAUTION

Always protect the valve body by using a damp cloth to prevent the valve from overheating. Do not braze with the valve body exceeding 250°F.

7)Install the new Drier.

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

9)Evacuate the system, and charge it with refrigerant. For air-cooled and water- cooled models, see the Nameplate for the required refrigerant charge. For remote air-cooled models, see the Charge Label in the machine compartment.
