Water Supply and Drains
Potable Water
• Water temperature must be between
40°F (4.4°C) and 90°F (32°C).
• Water pressure must be between
20 psi (140 kPa) and 80 psi (550 kPa).
• Minimum internal diameter of tubing 3/8" (10 mm).
Drain Connections
• Drain lines must have a 1.5 inch drop per 5 feet (2.5 cm
per meter) of run and must not create traps.
• The floor drain must be large enough to accommodate
drainage from all drains.
• Run separate bin and ice machine drain lines.
• Insulate drain lines to prevent condensation.
• Vent the ice machine drain to the atmosphere.
• Drain termination must have an air gap that meets
local code.
Auxiliary Base Drain Installation
An auxiliary drain is located in the ice machine base to
remove moisture in high humidity areas.
1. View the back of the ice machine base on the
compressor side and locate and remove the cap plug.
2. Route tubing to an open site drain:
• Use 1/2 inch CPVC tubing.
• Apply a bead of silicone around the exterior of the
ice machine tubing and insert into ice machine
base. The silicone will secure the tubing and
provide a watertight seal.
• Provide support for tubing.
