G. Removal and Replacement of Water-Cooled Condenser

CAUTION

1.Always install a new drier every time the sealed refrigeration system is opened.

2.Do not replace the drier until after all other repair or replacement has been made. Install the new drier with the arrow on the drier in the direction of the refrigerant flow.

3.When brazing, protect the drier by using a wet cloth to prevent the drier from overheating. Do not allow the drier to exceed 250°F (121°C).

1)Turn off the power supply.

2)Remove the panels.

3)Close the condenser water supply line shut-off valve. If connected to a closed loop water supply, also close the condenser return outlet shut-off valve.

4)Open the condenser water supply line drain valve. If connected to a closed loop water supply, also open the condenser return outlet drain valve.

5)Attach a compressed air or carbon dioxide supply to the condenser water supply line drain valve.

6)Open the water regulating valve by using a screwdriver to pry up on the spring retainer underneath the spring. While holding the valve open, blow out the condenser using the compressed air or carbon dioxide supply until water stops coming out.

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

8)Disconnect the condenser water inlet and outlet piping and the refrigeration inlet and outlet piping at the condenser.

9)Remove the old condenser and install the new condenser.

10)Remove the drier, then place the new drier in position.

11)Braze all fittings while purging with nitrogen gas flowing at a pressure of 3 to 4 PSIG.

12)Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of refrigerant to the system (if using an electronic leak detector), and then raise the pressure using nitrogen gas (140 PSIG). DO NOT use R-404A as a mixture with pressurized air for leak testing.

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

14)Close the drain valve(s). Open the condenser water supply line shut-off valve. If connected to a closed loop water supply, also open the condenser return outlet shut-off valve.

15)Check for water leaks.

16)Replace the panels in their correct positions.

17)Turn on the power supply.
