16) Connect the solderless terminals, and replace the terminal cover in its correct
position.
17) Refit the louver and rear cover in their correct positions.
18) Plug in the icemaker.
Note: Hoshizaki recommends that compressor starting electrics are always replaced at
the same time as the compressor.
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.
1) Unplug the icemaker.
2) Remove the rear cover.
3) Recover the refrigerant and store it in a proper container, if required by an applicable
law (see “V. 1. [b] REFRIGERANT RECOVERY”).
4) Remove the drier holder, if any, and pull the drier toward you for easy service.
5) Remove the drier using brazing equipment.
6) Braze or solder the new drier, with the arrow on the drier in the direction of the
refrigerant flow. Use nitrogen gas at a pressure of 0.2 - 0.3 bar when brazing
tubings. Braze in an access valve using a tee if necessary.
7) Check for leaks using nitrogen gas (10 bar) and soap bubbles.
8) Evacuate the system and charge it with refrigerant (see “V. 1. [d] EVACUATION AND
RECHARGE”).
9) Refit the rear cover in its correct position.
10) Plug in the icemaker.
Note: Always use a drier of the correct capacity and refrigerant type.
