9) Replace the panels in their correct positions.
10) Plug in the icemaker or connect the power source.
Note: Always use a drier of the correct capacity and refrigerant type.
4. EXPANSION VALVE
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) Unplug the icemaker or disconnect the power source.
2) Remove the top, front and right side panels.
3) Recover the refrigerant and store it in a proper container, if required by an applicable
law (See “1. [b] REFRIGERANT RECOVERY”).
4) Remove the expansion valve using brazing equipment. Protect the evaporator and
pipes from excessive heat with damp cloths or similar.
5) Remove the expansion valve sensor (bulb).
6) Remove the drier using brazing equipment.
7) Braze in the new expansion valve. Protect the body of the valve from excessive
heat, and use nitrogen at a pressure of 0.2 - 0.3 bar when brazing.
8) Braze or solder the new drier (See “3.
DRIER”).
9) Check for leaks using nitrogen gas (10
bar) and soap bubbles.
10) Evacuate the system and charge it with
refrigerant (See “1. [c] EVACUATION
AND RECHARGE”).
11) Attach the bulb to the suction line in
position. Be sure to secure it using a
wire or clamp and replace the insulation.
