7)Install the new condenser, then attach the fan motor bracket.

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

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

10)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.

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

12)Replace the panels in their correct positions.

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)Unplug the icemaker or disconnect the power source.

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.
