Sub-Zero PRO 48 Refrigeration
The importance of the installation of the Sub-Zero
PRO 48 unit cannot be overemphasized. Installation
should be done by a qualified installer.

mended that you read this entire installation guide. There
are key details that you should take special care to
observe during the installation. By reading these instruc-
tions carefully, you will make the installation process

Electrical Requirements
For PRO 48 models, the electrical supply should be
located within the shaded area shown in the illustration
below. Follow the National Electrical Code and local codes
and ordinances when installing the receptacle. A separate
circuit, servicing only this appliance is required. A ground
fault circuit interrupter (GFCI) is not recommended and
may cause interruption of operation.
Always shut power off at the circuit breaker before
performing any installation, service or maintenance.

PRO 48 Site Preparation 7

Plumbing Requirements
The PRO 48 has an automatic ice maker with an integrated
water filtration system. The water supply line should be
located within the shaded area shown in the illustration.
The water line must not interfere with installation of the
anti-tip bracket.
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.
A reverse osmosis system can be used provided there
is constant water pressure of 35 psi (2.4 bar) to 120 psi
(8.3 bar) supplied to the unit at all times. In this application,
the water filtration system must be bypassed. Refer to
water filter bypass mode on page 16. A copper line is not
recommended for this application.
IMPORTA T OTE: All installations must meet local
plumbing code requirements.
It is not recommended that the ice maker be connected to
a softened water supply. Water softener chemicals, such
as salt from a malfunctioning softener, can damage the
ice maker and lead to poor ice quality. If a softened water
supply cannot be avoided, make sure that the water
softener is well maintained and operating properly.
IMPORTA T OTE: Do not use with water that is microbi-
ologically unsafe or of unknown water quality without
adequate disinfection before or after the system. Systems
certified for cyst reduction may be used on disinfected
waters that may contain filterable cysts.

IMPORTA T OTE: For either wood or concrete floor
applications, if the wood screws do not hit a wall stud in
any of the upper holes on the anti-tip bracket, use the
provided #8–18 x 11/4" wood screw, #12 flat washer and
nylon zip-it wall anchor in its place.
IMPORTA T OTE: In some installations the subflooring
or finished floor may necessitate angling the screws used
to fasten the anti-tip bracket to the back wall.
Anti-Tip Bracket Installation
IMPORTA T OTE: Placement of the anti-tip bracket is
critical to a stable installation. Failure to properly position
the anti-tip bracket will prevent it from engaging the unit.
The anti-tip bracket must be installed exactly 26" (660)
from the front of the face frame of the unit to the back of
the anti-tip bracket. Also, the centering line on the lower
flange of the anti-tip bracket must be centered in the
rough opening. Make sure the anti-tip bracket is installed
on a solid base. Refer to the illustration below.
To properly secure the anti-tip bracket for a stable installa-
tion, use all anti-tip bracket hardware as instructed for
wood or concrete floors.
To prevent the PRO 48 from tipping forward and
provide a stable installation, the unit must be secured
in place with the anti-tip bracket provided with the unit.
Make sure there are no electrical wires or plumbing in
the area which the screws could penetrate.

Anti-Tip Bracket Installation
WOOD FLOOR APPLICATIO S
Use the twelve #12 x 21/2" wood screws and twelve #12
flat washers provided. Drill pilot holes 3/16"(5) diameter
maximum and make sure the screws penetrate through
the flooring material and into the wall plate a minimum of
3/4" (19). Make sure the screws hold tight. Refer to the
illustration below.
CO CRETE FLOOR APPLICATIO S
Use the three 3/8" x 33/4" concrete wedge anchors,
six #12 x 21/2" wood screws and six #12 flat washers
provided. Drill pilot holes 3/16"(5) diameter maximum and
make sure the screws penetrate through the flooring
material and into the wall plate a minimum of 3/4"(19).
Then drill 3/8"(10) diameter holes into the concrete a
minimum of 11/2"(38) deep. Make sure the anchors and
screws hold tight. Refer to the illustration below.
I STALL CO CRETE WEDGE A CHORS:
1) Drill a 3/8"(10) diameter hole any depth exceeding the
minimum embedment. Clean the hole or continue
drilling additional depth to accommodate drill fines.
Use a carbide drill bit manufactured within ANSI
B94.12-77.
2) Assemble the washer and nut flush with the end of
anchor to protect threads. Drive the anchor through the
material to be fastened until the washer is flush with
the surface material.
3) Expand the anchor by tightening the nut 3–5 turns past
hand-tight position or to 25 foot-pounds of torque.
Always wear safety glasses and use other necessary
protective devices or apparel when installing or
working with anchors.
Anchors are not recommended for use in lightweight
masonry material such as block or brick, or for use in
new concrete which has not had sufficient time to cure.
The use of core drills is not recommended to drill holes
for the anchors.

Grille Removal
In order to prevent damage to the PRO 48 grille, the top
grille assembly should be removed prior to moving the
unit.
To remove the grille assembly, pull out on the bottom edge
of the grille and tilt the grille frame forward. Disconnect the
network cables which connect the exterior temperature
displays on the grille to the display module. Cut the two
white cable ties which attach the network cables to the
right grille support and disconnect the cables. The cable
ties should be replaced with the extra cable ties provided,
once the unit is properly installed. Remove the three grille
bolts from base of the grille and the upper grille screw.
Remove the grille assembly. Refer to the illustrations
below.
Reverse this procedure to reinstall the grille assembly.
