Lock Installation
IMPORTANT NOTE: If you are adding an accessory lock kit
to your wine storage unit, it should be installed before you
position the unit. Installation instructions are included with
the lock kit.
For model 424, the lock is attached to the bottom of the
metal door frame. The decorative door panel is not
involved in the installation or operation of the lock. The
catch portion of the lock is attached to the bottom of the
appliance cabinet in pre-punched holes. When installing
the lock kit, it may be helpful to tip the unit on its back for
easier access.
POSITION THE UNIT
IMPORTANT NOTE: If for any reason the wine storage unit
has been laid on its back or side, you must allow the unit
to stand upright for a minimum of 24 hours before con-
necting power.
Plug the power supply cord into the 15 amp grounded
electrical outlet. With power applied to the appliance,
check for lighting and cooling before going any further.
Once you are satisfied that the unit is operating properly,
shut off power to the electrical outlet at the circuit breaker
and proceed.
If a home alarm system is to be used with the wine
storage unit, the lead wires should be threaded into the
compressor compartment before you position the unit.
Refer to home alarm connections on page 9, for the
location of these lead wires. After the unit is in position,
the alarm wiring can be completed from the front.
Pre-level the wine storage unit before sliding it into
position. Leveling cannot be completed with the unit
pushed back in the installation opening.
For model 424FS, adust the leveling legs so the top of the
unit is no more than 345/8" (879) above the floor. This is to
allow the unit to engage the anti-tip bracket properly.
Center the model 424FS in front of the anti-tip bracket.
Slide the unit into position, making sure the anti-tip
bracket is engaged properly.
IMPORTANT NOTE: When the wine storage unit is
installed, the anti-tip bracket will be positioned just below
the engaging bracket on the unit. It is not necessary to
raise the unit up so that it locks into the anti-tip bracket,
but the unit must be in alignment with the anti-tip bracket.
The wine storage unit provides the best access to its
contents when the front surface of the door panel extends
out from surrounding cabinets approximately 1/4" (6). For
model 424FS, if there are no surrounding cabinet surfaces
to gauge depth, slide the unit back until it engages the
anti-tip bracket.
IMPORTANT NOTE: The floor under the wine storage unit
must be at the same level as the surrounding finished floor
to allow for removal of the unit for servicing.
Shut off the power to the electrical outlet.

Level the nit
Using an adjustable wrench or pliers, turn each of the four
leveling legs clockwise to raise the unit and counterclock-
wise to lower the unit. Refer to the illustration below for
location of the leveling legs.
For model 424, the countertop bracket should be used
to make a solid installation. Refer to the illustration on
page 6. If this is not possible, wedge shims along the
sides and top.
Home Alarm Connections
Before the kickplate is installed, all necessary wiring
connections in the compressor compartment should be
completed.
If a home alarm system is to be installed on the wine
storage unit, the connections should be made using the
logic supplied with the alarm specifications. Refer to the
illustration for the appliance lead locations, and refer to
the following for color codes:
•Normally open contacts – white with red stripe wire
•Normally closed contacts – white with blue stripe wire
•Common – gray with white stripe wire
Use the 1/4" (6) spade terminals or wire nuts provided to
make the proper wiring connections.
IMPORTANT NOTE: If you are not responsible for alarm
system connection, this information should be supplied to
the home security system contractor.
Models 424 and 424FS Installation 9
subzero.com
The alarm circuit in the unit is intended as a low-
voltage, low-current device only. It should not be
used to switch line power.
Any unused terminals should be completely insu-
lated and all wires should be secured away from
conductive or moving components.
To reduce the possibility of the unit tipping forward,
the front leveling legs must be in contact with the
floor.

Kickplate Installation
Once the unit is leveled and wiring connections made, the
kickplate can be installed. Use the two #10 x 1/2" stain-
less steel screws that are provided with the kickplate.
Refer to the illustration below.
IMPORTANT NOTE: The kickplate must be removed for
servicing. The floor cannot interfere with removal. The
louvered section of the kickplate must not be covered so
as to prevent air circulation.
Turn power back on to the electrical outlet.
Door Panel—Model 424
Model 424 is offered in two design applications; stainless
steel (/S) and overlay (/O). Each of these designs are avail-
able as a glass door (G) model.
The stainless steel model 424/S is available as a glass
door (G) model only, with the classic finish and is shipped
from the factory with the decorative stainless steel door
panel and matching handle in place.
The overlay model 424/O is available as a glass door (G)
or solid door (S) model and is designed to accept a
decorative door panel to match surrounding cabinetry.
The door panel and the handle will be provided by the
customer.
Before beginning installation, check for the correct com-
ponents for the fit and finish desired. All overlay doors
require a decorative panel 233/4" (603) by 301/16" (764) and
a minimum 5/8" (16) thick.
IMPORTANT NOTE: For installations at or above 5,000'
(1524 m) in altitude, a special high altitude glass door unit
(HA) must be ordered.
If you have questions, contact your Sub-Zero dealer or
cabinet supplier. Additional panel information can be
found in the Sub-Zero design guide.
Models 424 and 424FS Installation 10
KICKPLATE
Kickplate installation.
A solid panel must not be installed on a glass door
unit, as this may cause moisture to form behind the
panel.

Overlay Door Panel—Model 424
Inspect the door panel for the minimum 5/8"(16) thickness,
the finished inside edge. The glass door has a 10 lbs (5 kg)
weight limit and the solid door has a 20 lb (9 kg) weight
limit. Refer to the wine storage section of the Sub-Zero
design guide for additional panel information.
Decide if the handle will be attached through the glass
door frame or just through the decorative door panel. If it
is just through the door panel, the handle must be
attached first.
Decorative panels are attached to the model 424 door
using #8 x 5/8" square drive screws passing through the
door frame from the rear, behind the gasket into the panel.
The door panel is marked for screw locations by the use of
‘tenon centers’, which are temporarily inserted into the
1/4" (6) diameter holes in the front of the glass door frame.
Refer to the illustration below.
With the wine storage unit secured in position and the
door closed, the panel is held in the desired position on
the door and rapped by hand from the front, putting center
marks on the rear surface of the panel. If the door panel is
made of such a material that pre-drilling is needed, all of
the mounting holes should be marked. If not, only enough
holes to hold the panel in place temporarily, are necessary.
The door panel is then lowered from the door frame, tenon
centers removed, the door opened and the screws driven
into the panel through the black tape on the door frame,
using the center marks to locate the screws.
The screw holes inside the door are hidden under a cover
flap on the door gasket. It is necessary to lift the flap to
insert the screws. Use as many screws as necessary to
hold the door panel in place properly.
IMPORTANT NOTE: After the first three or four mounting
screws are in place, but not completely tightened, close
the door and check your panel fit. This is the time to make
small adjustments. Once you are satisfied with the appear-
ance, open the door and apply the remainder of the
screws. Check all screws for tightness.
The metal frame on the glass door has numerous
mounting holes on each side of the door. This is to accom-
modate the Sub-Zero accessory handles and provide for
easy attachment of the handle through the door frame.
If you choose not to use the pre-drilled handle mounting
holes, it will be necessary to fasten the handle from the
rear of the door panel only, or drill one or more additional
holes through the metal frame of the glass door.
The cross section illustration shows how this hole passes
through the door frame. The hole center is on the small
locator groove in the front of the frame. A 1/4" (6) diameter
hole is made in the front wall of the extrusion and a 13/32"
(11) diameter hole through the rest of the frame.

Overlay Door Panel—Model 424
IMPORTANT NOTE: Install screws in all the mounting holes
in the door frame. The nature of the door panel with a
narrow outer rim and no connecting center member
requires the support provided by the glass door.
After the door panel installation is complete, apply the
cover patches or plugs provided over the holes on the
inside surface of the door.
The cover patches or plugs are part of the insulation
system on the door of the wine storage unit. Be sure
to cover all the holes in the door that were used.
The wine storage unit door is made with a sealed
double wall tempered glass core. The drill must not
contact this core when drilling. Be sure the hole is
centered on the small groove in the front of the door
frame and the drill passes squarely through the
frame. If you are inexperienced with drilling, fasten
the handle from the rear of the door panel only.

Hinge Adjustment
IMPORTANT NOTE: The wine storage unit must be
installed and leveled before door hinge adjustments can
be made.
The top and bottom cabinet hinges on models 424 and
424FS are held in place with three permanent adjustment
screws and two shipping screws. Refer to the illustrations
below. The shipping screws must be removed and dis-
carded to adjust the door alignment and fit. If no adjust-
ments are necessary, it is recommended that all five
screws remain in place.
On the model 424FS, only the bottom door hinge can be
adjusted. Remove and discard the two shipping screws
and loosen the three hinge screws to adjust the door.
Refer to illustration 12.

If a home alarm system is to be used with the wine
storage unit, the lead wires should be threaded into the
compressor compartment before you position the unit.
Refer to wiring connections on page 20 for the location of
these lead wires. After the unit is in position, the alarm
wiring can be completed from the front.
Pre-level the wine storage unit before rolling into position.
This is to allow the unit to engage the anti-tip bracket
properly.
Roll the unit into position, making sure the anti-tip bracket
is engaged properly. Screw the front leveling legs out
approximately 3/16" (5) to make any future adjustments
easier.
IMPORTANT NOTE: When the wine storage unit is
installed, the anti-tip bracket will be positioned just below
the engaging bracket on the unit. It is not necessary to
raise the unit up so that it locks into the anti-tip bracket,
but the unit must be in alignment with the anti-tip bracket.
IMPORTANT NOTE: The floor under the wine storage unit
must be at the same level as the surrounding finished floor
to allow for removal of the unit for servicing.
Shut off the power to the electrical outlet.

Leveling
Level the unit by turning the front leveling legs clockwise
to raise the unit, or counterclockwise to lower it. To assist
you in adjusting the front leveling legs up or down, use a
standard screwdriver blade and place it in the front
leveling leg as shown in the illustration below.
The rear leveling legs are adjusted from the front of the
base by turning the Phillips head screw. Refer to the illus-
tration below.
IMPORTANT NOTE: The rear leveling legs will only move
1/16" (2) for every 18 revolutions on the Phillips head screw.
Do not over torque. Use the lowest torque setting on any
power screwdriver. Do not turn the rear leveling legs by
hand. Damage will occur if you turn these legs.
Install Molding
The decorative white molding strips for the top and sides
of models 427 and 427R can be snapped into place as
shown in the illustrations below. The top molding piece
must be installed before the side molding can be
attached. For installations where units are positioned side
by side, refer to side panels on page 25.
