Water-Cooled Condenser - Hoshizaki DCM-500B H Instruction Manual

2. Water-Cooled Condenser

a) Connection to an Open Drain System
• Condenser water supply inlet is 1/2" female pipe thread (FPT). A minimum of
1/4" nominal ID copper water tubing or equivalent is required for the condenser water
supply line.
• A condenser water supply line shut-off valve and drain valve should be installed.
• Condenser drain outlet is 3/8" FPT. A minimum of 1/4" nominal ID hard pipe or
equivalent is required for the condenser drain line.
• In some areas, a back flow preventer may be required in the condenser water supply
line.
• In order to maintain the proper high side pressure, the condenser water supply
inlet temperature should not drop below 45°F (7°C) and the condenser drain
outlet temperature must be in the 104°F to 115°F (40°C to 46°C) range. Once the
icemaker installation is complete, confirm the condenser drain outlet temperature
5 minutes after a freeze cycle starts. If the condenser drain outlet temperature is
not in the proper range, use a flat blade screwdriver to rotate the adjustment screw
on the water-regulating valve until the temperature is in the proper range (rotate
counterclockwise to raise temperature or clockwise to lower temperature).
