4. 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.

2) Remove the Rear Cover.
3) Recover the refrigerant and store it in a proper container, if required by an applicable
law (see “1. [b] REFRIGERANT RECOVERY”).

5) Remove the Drier using brazing equipment.
6) Braze the new Drier, with the arrow on the Drier in the direction of the refrigerant
flow. Use nitrogen gas at a pressure of 3 - 4 PSIG when brazing tubings. Braze in
an Access Valve using a tee if necessary.
7) Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.
8) Evacuate the system and charge it with refrigerant (see “1. [c] EVACUATION AND
RECHARGE”).
9) Refit the Rear Cover in its correct position.
10) Plug in the icemaker or connect the power source.
