MODEL 315I(P) – GRAVITY DRAIN
OR DRAIN PUMP
The Undercounter ice maker can be ordered with
a pump (Model 315IP) or without a pump (Model
315I). The model without a drain pump drains its
water by gravity. However, the gravity drain
model may be converted to a pump model
through the installation of a drain pump kit and
drain pump.
Specific step-by-step instructions are included
with the drain pump kit. Contact your Sub-Zero
dealer for specifics.
The drain and inlet water tubes must be
plumbed before connecting to the ice maker. For
the gravity drain, all horizontal runs of drain lines
must have a
1
/4" (6) per 12" (305) fall. An air gap
will likely be required between the ice maker
drain tube and the drain/waste receptacle. A
stand pipe with a trap below it would be accept-
able for the drain/waste receptacle. Refer to the
illustrations below.
IMPORTANT NOTE: Poor drainage will cause a
high rate of ice melting in the bin.
