13)Install the new drier (see “4. DRIER”).
14)Check for leaks using nitrogen gas (10 bar) and soap bubbles.
15)Evacuate the system and charge it with refrigerant (see “1. [c] EVACUATION AND RECHARGE”).
16)Connect the solderless terminals and replace the terminal cover in its correct position.
17)Refit the panels in their correct positions.
18)Plug in the icemaker or connect the power source.
Note: Hoshizaki recommends that compressor starting electrics are always replaced at the same time as the compressor.
4. DRIER
CAUTION
1.Always install a new drier every time the sealed refrigeration system is opened.
2.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 flow.
3.When brazing, protect the drier by using a wet cloth to prevent the drier from overheating. Do not allow the drier to exceed 250°F (121°C).
1)Unplug the icemaker or disconnect the power source.
2)Remove the top panel and rear panel.
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 drier holder, if any, and pull the drier toward you for easy service.
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 0.2 - 0.3 bar when brazing tubings. Braze in an access valve using a tee if necessary.
