D. Removal and Replacement of Drier
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. Unplug the icemaker.
2) Remove the panels.
3) Recover the refrigerant and store it in an approved container. (See “V.A.1. Refrigerant
Recovery”.)
4) Remove the drier.
5) Install the new drier with the arrow on the drier in the direction of the refrigerant flow.
Use nitrogen gas at a pressure of 3 to 4 psig (.21 to .28 bar) when brazing the tubings.
6) Check for leaks using nitrogen gas at 140 psig (9.65 bar) and soap bubbles.
7) Evacuate the system and charge it with refrigerant. See the nameplate for the required
refrigerant charge. (See “V.A.2. Evacuation and Recharge [R-404A]”.)
8) Replace the panels in their correct positions.
9) Plug in the icemaker. Turn on the power supply.
