Refer to the illustrations and specifications
for overall dimensions, finished rough opening
dimensions and installation specifics.
This ice maker unit 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
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 details. To obtain local
dealer information, visit the Locator section of
our website, subzero.com.
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 1' (305) fall. An
air gap will likely be required between the ice
maker drain tube and the drain / waste recepta-
cle. A stand pipe with a trap below it would be
acceptable for the drain / waste receptacle. Refer
to the installation illustrations for the Model
315I (gravity drain) and the Model 315IP (drain
pump) on page 3.
For Model 315I (gravity drain), the drain
must be located in a 2" (51) area centered in
the opening for the unit, 23" (651) back from
the front door.
Poor draining will cause a high rate of ice
melting in the bin.
Dimensions in parentheses are in
millimeters unless otherwise specified.
Rough in the water supply line. Connect a
1
/ " OD copper line to the house supply, being
4
sure to use an easily accessible shut off valve
between the supply and the unit.
Do not use self-piercing valves. A saddle
valve kit (4200880) is available from your
Sub-Zero dealer. To obtain local dealer informa-
tion, visit the Locator section of our website,
subzero.com.
A line filter is required when water condi-
tions have a high sediment content. The ice
maker operates on water pressure of 20 psi
(1.4 bar) to 100 psi (6.9 bar). In some cases a
reverse osmosis water filter system may not be
able to maintain the minimum water pressure
consistently.
A 115 V AC, 60 Hz, 15 amp fused electrical
supply is required. It is recommended that a
separate circuit, serving only this appliance, be
provided.
All Undercounter models are equipped with a
power supply cord with a 3-prong grounding
plug which must be plugged into a mating
3-prong grounding type wall receptacle. Locate
electrical as shown in the illustrations on
page 3.
You must follow all National Electrical Code
regulations. In addition, be aware of local codes
and ordinances when installing your service.
