SHIPPING BRACKET REMOVAL / TOE-KICK REMOVAL / REMOVAL FROM SKID / CASE ALIGNMENT
1. Removing Shipping Brackets Attached
To Skid
• Remove screws holding case shipping brackets to
skid.
• Remove case shipping brackets from skid.
• See illustrations at right. Note: Shipping brackets
will vary in size, shape, material and location
depending upon case type and model.
2. Remove Front / Rear Toe-Kicks Before
Removing From Skid
• Toe-kicks are normally shipped separately.
• If toe-kicks are attached to case, they must be
removed.
• Toe-kicks may be attached to case via slot /magnet
method.
• Remove toe-kick by pulling away from lower
magnet and lifting up and off hooks.
• No screw removal is required.
• See illustrations at mid-right.
3. Remove Case From Skid
• Important! If case is shipped with levelers, they will
be in the DOWN position (for stability). To prevent
damage to the case, all levelers must be raised
ALL THE WAY UP before moving unit off skid and
into position.
• To prevent damage, support case while sliding
it toward edge of skid).
• IF NO CASTERS ARE ON SKID, tip case
slightly back and slide skid from underside of
case. When case is at edge of skid, carefully
lower to floor (so two levelers rest on floor).
• IF CASTERS ARE ON CASE, it may be rolled
off skid via ramp (as shown in lower-right
illustration).
• Carefully slide skid out from under case.
• After removal of case from skid, place into
position.
• Note: Illustration below-right may not reflect your
particular model or options).
4. Position/Align Case Alongside Other Cases

CASE ADJOINMENT: URETHANE AND SILICONE APPLICATION / BOLTING ADJOINED UNITS
Case Adjoinment
>> Warranty is void if improper urethane/sealant is used
in this process.
>> Lay generous beads of caulk/sealant as specified.
A. Prior To Adjoinment - Apply Industrial Grade
Urethane Adhesive (As Shown In Below Illustration)
• Lay a generous bead of industrial grade urethane
adhesive in non-visible areas (as illustrated below).
• This urethane adhesive prevents refrigerated air
from escaping between cases (causing
condensation and reducing refrigeration efficiency)
as well as preventing insects from entering the case.
• See industrial grade urethane adhesive illustration
below-left.
B. Adjoining Cases - Using Bolts and Nuts
• Use appropriately sized nuts and bolts for each hole.
#1 - Hole is accessible at underside of top surface
support.
#2 - Holes are accessible through rear plenum and
behind honeycomb air diffuser.
#3 - Holes are accessible at underside of decking.
Decking must be removed to attach bolts/nuts.
#4 - Holes are accessible at base frame (through front of
case after front toe-kicks have been removed).
• Tighten nuts securely (but do not over-tighten).
• See accompanying illustration below.
C. After Adjoinment - Apply Food Grade Silicone Sealant
To Inner And Outer Seams
• After all nuts/bolts are securely attached to case, apply a
generous bead of food grade silicone sealant at both
inner and outer adjoinment seams.
• When properly applied, this food grade silicone sealant
will prevent water from seeping between cases (into the
case or to the floor) as well as crumbs or other residue
from entering between case seams.
• See silicone sealant illustration below-left.
>> You must reattach toe-kick and decking after case
adjoinment process is complete.

• Illustration at top-left shows case with frame
support rails.
• Shims will be provided on cases with frame
support rails.
• Use shims to level case.
2. Cases With Levelers: Adjust
• Important! For cases with casters, after case is in
proper position, levelers must then be
LOWERED to floor.
Frame
Support Rails
• Adjust case so it is level and plumb.
• You may need to remove front and/or rear
toe-kick to access levelers.
• Use adjustable wrench (and possibly a pry bar)
to adjust leveler.
• Do not use pry bar on toe-kick (it may buckle).
• Do not use pry bar on end panel (it may chip).
