ELECTRICAL REQUIREMENTS
A 220-240 V AC, 50/60 Hz, 10 amp circuit
breaker and electrical supply are required. A
separate circuit, servicing only this appliance,
is required. Locate the electrical outlet within
the shaded area indicated in the Installation
Specifications illustration on the previous
page.
The PRO 48 is equipped with a detachable
power supply cord with a 3-prong grounding
plug, which must be plugged into a mating
3-prong grounding-type wall receptacle. Follow
local codes and ordinances when installing the
receptacle.
IMPORTANT NOTE: A ground fault circuit
interrupter (GFCI) is not recommended and
may cause interruption of operation.
IMPORTANT NOTE: The PRO 48 is equipped
with an appliance inlet type device. This allows
easy replacement of the power cord. The appli-
ance inlet is located on top of the unit on the
compressor shroud.
Do not use an extension cord or two
prong adapter. Electrical ground is
required on this appliance. Do not remove
the power supply cord ground prong.
The outlet must be checked by a qualified
electrician to be sure that it is wired with
the correct polarity. Verify that the outlet
provides 115 volts and is properly
grounded.
Always shut power off at the circuit
breaker before performing any installa-
tion, service or maintenance.
PRO 48 INSTALLATION INSTRUCTIONS

11
PLUMBING REQUIREMENTS
The PRO 48 has an automatic ice maker. This
system operates on water pressure between
1.4 bar and 8.3 bar.
Rough in the cold water supply line using
6,35 mm OD copper line. The water line should
be routed up through the floor within 13 mm
from the back wall and no higher than 76 mm
off the floor. If you have to come through the
wall, make sure the water line is no more than
76 mm from the floor.
Regardless of the routing, allow .9 m of excess
copper tubing to remain outside the wall or
floor for easy connection to the unit. Locate
the water supply line within the shaded area
indicated in the Installation Specifications illus-
tration on the previous page.
Use an easily accessible shut-off valve
between the water supply and the unit. Do not
use self-piercing valves. A saddle valve kit
(part #4200880) is available from your
Sub-Zero dealer.
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, be
sure that the water softener is well maintained
and operating properly.
IMPORTANT NOTE: Do not use with water
that is microbiologically 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.
MPORTANT NOTE: All installations must
meet local plumbing code requirements.
IMPORTANT NOTE: A reverse osmosis
system can be used, provided there is constant
water pressure of 1.4 bar to 8.3 bar supplied to
the unit at all times.

PRO 48 INSTALLATION INSTRUCTIONS
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 shipped with the unit
IMPORTANT NOTE: Placement of the anti-tip
bracket is critical to a stable installation. It
must be installed exactly 660 mm 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. Failure to
properly position the anti-tip bracket will
prevent it from engaging the unit. Be sure that
the anti-tip bracket is installed on a solid base.
Refer to the illustrations below.
IMPORTANT NOTE: For a stable installation,
be sure to use all anti-tip bracket hardware as
instructed for wood or concrete floors to
properly secure the bracket.
Wood floors
Make sure that there are no electrical
wires or plumbing in the area which the
screws could penetrate.
WOOD FLOOR APPLICATIONS
Use the twelve #12 x 51mm wood screws and
the twelve #12 flat washers provided. Drill
pilot holes 5 mm diameter maximum and be
sure that the screws penetrate through the
flooring material and into the wall plate a
minimum of 19. Be sure that the screws hold
tight. Refer to the illustration below.
IMPORTANT NOTE: 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
31,75 mm wood screw, #12 flat washer and
nylon zip-it wall anchor in its place.
IMPORTANT NOTE: In some installations the
subflooring or finished floor may necessitate
angling the wood screws used to fasten the
anti-tip bracket to the back wall. Refer to the
illustration below.

CONCRETE FLOOR APPLICATIONS
Use the three 10 x 95,25 mm concrete wedge
anchors, six #12 x 63,5 mm wood screws and
six #12 flat washers provided. Be sure that the
anchors and screws hold tight. Refer to the
illustration below.
IMPORTANT NOTE: 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
31,75 mm wood screw, #12 flat washer and
nylon zip-it wall anchor in its place.
IMPORTANT NOTE: In some installations the
subflooring or finished floor may necessitate
angling the wood screws used to fasten the
anti-tip bracket to the back wall. Refer to the
illustration below.

ANTI-TIP BRACKET INSTALLATION
INSTALL CONCRETE WEDGE ANCHORS
1) Drill a 10 mm 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.
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.
Concrete floors
Make sure that there are no electrical
wires or plumbing in the area which the
screws could penetrate.

PRO 48 INSTALLATION INSTRUCTIONS
MOVING THE PRO 48
After you've completed the steps for unpack-
ing the PRO 48 and have removed the grille
and installed the anti-tip bracket, carefully
move the unit onto an appliance dolly. When
securing the unit on the appliance dolly, use
the corner protectors retained from the pack-
aging under the strapping to avoid damage to
the stainless steel exterior. Also, secure the
doors and drawers closed with the strapping.
Refer to the illustration below for proper
placement of the appliance dolly.
IMPORTANT NOTE: Protect the surrounding
finished flooring with masonite, plywood,
3 mm pressed fiberboard or other suitable
material before moving the unit across it.
Carefully move the PRO 48 into place near the
rough opening and move it off of the appliance
dolly. The PRO 48 is equipped with rollers, so it
can be moved into position more easily.
The PRO 48 is very heavy – 401 kg or
408 kg – be sure to have adequate
manpower when moving and positioning
the unit. Secure doors and drawers
closed before moving the unit.
Proper placement of appliance dolly
Retract the front leveling legs all the way up to
allow the unit to be moved into position more
easily. You will extend the front leveling legs
down and adjust once the unit is in position.
IMPORTANT NOTE: The rear levelers must be
in their lowest position in order to push the
unit back into the rough opening. Therefore,
leveling cannot be completed until the unit is
in position.
Shut off power to the wall outlet. Plug the
power supply cord into the 10 amp grounded
outlet and roll the unit into position. Be sure
that the anti-tip bracket is properly engaged.
IMPORTANT NOTE: If for any reason the unit
has been laid on its back or side, you must
allow the unit to stand upright for a minimum
of 24 hours before connecting power.

PRO 48 INSTALLATION INSTRUCTIONS
LEVELING THE UNIT
Once the unit is in position, extend the front
leveling legs down by turning the legs
counterclockwise and adjust the height. The
rear height adjustment can be made from
the front of the base. Use a 8 mm socket to
adjust the rear rollers. Turn the 8 mm hex
bolt clockwise to raise the unit or counter-
clockwise to lower it.
When the unit is leveled properly, or squared
off, door and/or drawer adjustments are less
likely to be necessary. Refer to the illustra-
tion below for location of the rear roller base
adjustment.
IMPORTANT NOTE: Be sure to reference
leveling of the unit to the floor and not to
surrounding cabinetry. This could affect the
operation of the unit, such as doors not
closing properly.
INSTALL THE KICKPLATE
To install, screw the kickplate to brackets
attached to the inside surface of each roller
base.
Rear roller base adjustment
WATER LINE CONNECTION
Approximately 0,9 m of 6,35 mm plastic
tubing is connected to the ice maker with a
preassembled 6,35 mm compression
connection at the end. This tubing is located
under the unit.
The water line fitting connection kit,
provided with the unit, contains a 6,35 mm
compression sleeve and a 6,35 mm compres-
sion nut for connection to the household
water line. Place the compression nut and
sleeve on the water line and fasten to the
connection at the end of the tubing under
the unit. Do not over tighten. Check all water
line fittings for leaks. Make sure that the
drain pan can be installed or removed
without any water line interference.
IMPORTANT NOTE: Be sure to purge the
water line prior to final connection to the
unit. This will remove any debris that may
be present in the tubing from installing the
new water line.
IMPORTANT NOTE: Let your customer
know that the ice maker will not produce ice
immediately, and that the first bucket of ice
produced should be discarded. Allow 48
hours of ice production, before discarding
the first bucket of ice.
