Sub-Zero 400 Series Service-Handbuch

INSTALLATION CONSIDERATIONS:

This section covers some of the more common installa-

tion issues seen by a service technician. An improper

installation, though not a valid service issue, has the

potential to lead to a customer placing a call for service.

Installation related customer complaints could include,

but are not limited to: Unit leveling, unit movement,

door misalignment, doors and drawers not sealing,

internal frost or condensation, warm compartment tem-

peratures, exterior condensation, etc.

NOTE: Always refer to the Installation Manual whenev-

er installation related concerns arise, or contact the

Sub-Zero Customer Service Department.

Unit Leveling (Model 424)

Unlike the other 400 Series units, the model 424 must

be leveled before it is installed into the rough-in open-

ing. (See WARNING above). To level the model 424,

place it in front of the rough-in opening. Then, turn

each of the four leveling legs clockwise to raise the unit,

counterclockwise to lower the unit. (See Figure 2-1)

An adjustable wrench or pliers may be needed.

NOTE: If removing a 424 from its installation, an anti-

tip bracket and a countertop bracket may have been

used to make a solid installation. (See Figures 2-2) If

the brackets were not used, shims may have been

wedged along the sides and top.

Unit Leveling (Models 427 & 427R)

NOTE: The unit must be in the correct installation posi-

tion before leveling. (See WARNING above). The kick-

plate/grille must be removed before leveling. (See

Figure 2-3) If the unit has already been anchored to

the cabinets, the side molding strips must be removed

and the anchor screws must be extracted from the unit

to cabinet brackets before leveling. (See Figure 2-4)

These components must be reinstalled after leveling.

To level the unit, turn the front leveling legs counter-

clockwise to raise the front or clockwise to lower it. To

assist in turning the front leveling legs up or down, use

power screwdriver. Do not turn rear leveling legs by

hand. Damage will occur if you turn these legs by

hand.

Unit Leveling (Model 430)

NOTE: The unit must be in the correct installation posi-

tion before leveling (See WARNING on previous page).

The kickplate must be removed before leveling. (See

nets, the anchor screws must be extracted before level-

ing, then reinstalled after leveling.

To level the unit, turn the front leveling legs counter-

clockwise to raise the front or clockwise to lower it. To

assist in turning the front leveling legs up or down, use

a standard screwdriver blade and place it in the foot of

the front leg. (See Figure 2-5 & 2-8)

The rear levelers are adjusted from the front of the

base, using a 5/16” socket wrench. (The long adjusting

screw just above the front leveler leg reaches all the

way to the rear leveler/roller assembly.) Turn the

adjusting screw clockwise to raise the rear or counter-

clockwise to lower it. (See Figure 2-8)

Door Adjustment (Model 424)

NOTE: The unit must be level before adjusting the

door.

If the unit is properly installed, blocked and leveled, it

may still be necessary to adjust the door(s) from left to

right and/or in & out. Adjustments are performed at the

top and/or bottom cabinet hinge(s).

NOTE: The door hinges on the 424 are non-adjustable.

To access and adjust the cabinet hinge(s), it will be

necessary to pull the unit out approximately 6” from the

rough-in opening. (See NOTE below.) Working on

only one hinge at a time and using a 1/8” Allen wrench,

loosen the three cabinet hinge screws, then “snug”

them back down. (See Figure 2-9) Adjust door left to

right, or in and out. After adjusting the door, re-tighten

the screws and check for proper gasket seating.

NOTE: If removing a model 424 from its installation, an

anti-tip bracket and a countertop bracket may have

been used to make a solid installation. (See Figures 2-

2) If the brackets were not used, shims may have been

wedged along the sides and top.

Door and Drawer Adjustment (Models 427 & 427R)

NOTE:The door on models 427 and 427R, as well as

the drawers on the 427R are non-adjustable. Instead,

the door and/or drawer panels must be adjusted if there

is an alignment problem. Refer to the Installation

Manual.

NOTE: The unit must be level before attempting to

adjust the door and drawer panels.

Door Stop Adjustment (Models 427 & 427R)

The models 427 and 427R have a 90° door stop cam

built into the hinge system. The 90° door stop cam is

located in the center portion of the hinge. To adjust it,

use a standard straight-blade screwdriver to rotate the

cam until you reach the stop point. (See Figure 2-12)

NOTE: You must make this adjustment at both bottom

and top hinge.

Door Stop Installation (Model 430)

For the model 430, optional 90° and 105° door stops

are available, free of charge from Parts Distributors

and/or Product Distributors. The part number for the
