Drain Pump - Sub-Zero BI-36UFD Design Manual

Undercounter Refrigeration
Planning Information
PLUMBING REQUIREMENTS
For model UC-24C(I) and ice machine models, the water
supply line should be located within the shaded area
shown in the illustrations below. The water supply line
should be connected to the house supply with an easily
accessible shut-off valve between the supply and the
unit. Do not use self-piercing valves. A saddle valve kit is
available through your authorized Sub-Zero dealer.
IMPORTANT NOTE: A reverse osmosis system can be
used provided there is constant water pressure of 20 psi
to 100 psi
(1.4 bar) (6.9 bar)
A copper line is not recommended for this application.

Drain Pump

ICE MACHINE MODELS
Undercounter ice machine models can be ordered with or
without a pump. Models without a drain pump will drain
water from the unit by gravity. A drain must be installed.
The drain and inlet water tubes must be plumbed before
connecting to the ice machine. For the gravity drain, all
horizontal runs of drain lines must have a
fall. An air gap will likely be required between the unit
(305)
and drain receptacle. A stand pipe with a trap below it
would be acceptable for the drain receptacle.
IMPORTANT NOTE: Poor drainage will cause excessive ice
melting in the ice bin.
