Installation Manual

Plumbing Requirements

All models require connection to cold, potable
water. A hand actuated valve within site of the
machine is required. A 3/4 GAS BSPP inlet water
adapter and copper washer ship in the bin. Use
them to connect to the 3/8" male flare connection at
the back of the cabinet.
Water cooled models have a 1/2" FPT drain fitting
plus a 3/8" FPT condenser inlet water connection.
Water 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.
Install new tubing when replacing a prior ice
machine.

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 200 mm 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 6 mm fall per
meter of run for proper draining.
Follow all applicable codes.
