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" anti-back flow
air gap between the float valve orifice and the
highest possible reservoir water level; no back flow
device is required for the potable water inlet.
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.
