H. Removal and Replacement of Remote Air-Cooled Condenser
CAUTION
. 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. Install the new drier with the arrow on the drier in the direction of the
refrigerant ow.
3. When brazing, protect the drier by using a wet cloth to prevent the drier from
overheating. Do not allow the drier to exceed 50°F (°C).
) Turn off the power supply.
) Remove the icemaker panels.
3) Recover the refrigerant and store it in an approved container.
4) Remove the condenser unit panels.
5) Disconnect the condenser inlet and outlet piping.
6) Remove the screws securing the condenser to the base of the unit, then remove the
condenser.
7) Remove the shroud from the condenser and attach to the new condenser.
8) Install the new condenser.
9) Remove the drier (located in the icemaker), then place the new drier in position.
0) Braze all ttings while purging with nitrogen gas owing at a pressure of 3 to 4 PSIG.
) 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 (40 PSIG). DO NOT use R-404A as a mixture with
pressurized air for leak testing.
) Evacuate the system, and charge it with refrigerant. See the rating label inside the
icemaker for the required refrigerant charge.
3) Replace the panels in their correct positions.
4) Turn on the power supply.
