CU1526, CU2026, CU3030 User Manual
Plumbing Requirements
Connect to cold, potable water. A hand actuated valve within site of the machine is required. Air cooled models have a single 3/8” male flare inlet water connection. Water cooled models have an additional 3/8” FPT condenser inlet water connection, and a 1/2" FPT condenser drain.
Water Supply and Filters
If connecting to water filtration, filter only the water to the reservoir, not to the condenser. Install a new filter cartridge.
All models require drain tubing to be attached to them. Air cooled models have a single ¾” FPT drain fitting in the back of the cabinet. Water cooled models have the same fitting plus an additional ½” FPT drain fitting in the back of the cabinet.
Install new tubing when replacing a prior ice machine, as the tubing will have been sized for the old model and might not be correct for this one.
1.Connect water supply to water inlet fittings. 3/8" OD tubing is recommended.
Note: This NSF listed model has a 1"
2.Connect drain tubing to drain fittings.
3.Route the drain tubing to building drain. Follow local codes for air gap.
Drain Tubing
Use rigid drain tubes and route them separately – do not Tee into the bin’s drain and, if water cooled, do not Tee the condenser drain into the reservoir or bin drain.
Vent the reservoir drain. A vertical vent at the back of the drain, extended about 8 - 10" will allow the gravity drain to empty and also keep any surges during draining from discharging water out the vent.
Horizontal runs of drain tubing need a ¼” fall per foot of run for proper draining.
Follow all applicable codes.
