MODELS 315I AND 315IP –
GRAVITY DRAIN OR DRAIN PUMP
This ice maker can be ordered with a pump
(Model 315IP) or without a pump (Model 315I).
Models without a drain pump drain their water
by gravity. However, gravity drain models may be
converted to pump models through the installa-
tion 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.
