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 fi ttings while purging with nitrogen gas fl owing 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) Plug in the icemaker or connect the power source.
9. FAN MOTOR (AIR-COOLED MODEL)
1) Unplug the icemaker or disconnect the power source.
2) Remove the top panel, rear panel and side panel (L).
3) Disconnect the connector of the fan motor lead.
4) Remove the four screws securing the fan motor bracket and pull out the fan motor in
the arrow direction. To prevent deformation, do not hit the fan on the condenser or
other parts.
