If N.E.C. (National Electric Code) or your local code requires

GFCI (Ground Fault Circuit Interrupter) protection,

you MUST use a GFCI breaker in lieu of a GFCI receptacle.

CAUTION!

DO NOT RELY ON THERMOMETERS OR THERMOSTATS

FOR ACTUAL PRODUCT (FOOD) TEMPERATURES.

 Thermometers & thermostats reflect air temperatures ONLY.

 For ACTUAL product (food) temperatures, use a calibrated

food thermometer.

INSTALLATION: REMOVAL FROM SKID, REMOVING LOWER FRONT PANELS

1. Remove Case From Skid

 Remove shipping brace that may be

securing case to skid.

 Support case to prevent tipping.

 Caution! Rails can be damaged if case hits

floor with heavy force!

Case can be repositioned with pallet truck when

front lower panel is removed. Blocking may be

necessary to obtain adequate height.

Slide Skid Out

 Carefully slide unit to

rear of skid and tip

backward off skid.

 Illustration may not

reflect every feature

or option of your

particular case.

2. Remove Case From Skid (Casters)

Remove shipping brackets that may be securing

casters to skid

 Place ramp up against skid (to allow case to

smoothly slide off from skid).

 Maintain support of case at all times or center

of gravity may cause case to fall.

 Unlock Casters. Roll unit to rear of skid.

3. Removing Vertical Lower Front Panel (and Rear Panel)

 No screw removal is required to remove lower front/rear panel.

 Simply lift panel slots up and off case hooks.

 Replace in same manner it was removed.

 Note: Illustrations below may not exactly reflect every feature or option of your particular case.

INSTALLATION, CONT’D: CASE ADJOINMENT INSTRUCTIONS

4. Case Adjoinment Instructions

>> Warranty is void if improper sealant/urethane is used.

>> Lay generous beads of sealant/urethane as specified.

A. Prior To Adjoinment - Apply Industrial Grade

Urethane Adhesive at Center of Uprights

 Lay a generous bead of industrial grade urethane

adhesive at center of uprights (in non-visible areas).

 This urethane adhesive prevents refrigerated air from

escaping between cases (causing condensation and

reducing refrigeration efficiency) as well as preventing

ants or other insects from entering 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 through rear sliding door (if you

are able to avoid gas cylinder, attach bolt); otherwise

start at #2 in bolt/nut attachment process.

#2 - Holes are accessible through rear sliding door.

#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-kick has been removed).

 Tighten nuts securely (but do not over-tighten).

 See 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 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.

INSTALLATION, CONT’D: FRAME SUPPORT RAIL SHIMMING

5. Position & Align Case Alongside Other

Cases

 Before adjusting levelers (or shimming frame

support rails), make certain that the case is in

proper position and, if required, aligned with

adjoining case.

 This may require the repositioning of the case

you are installing or the already positioned case.

 Though case below shows both end panels,

case adjoinments routinely consist of end panel

removal for case-to-case placement.

Frame Support

Rails

6. Frame Support Rails Must Be Shimmed

 Illustration below shows case with frame

support rails.

 Shims will be provided with all cases that have

frame support rails.

 Use shims to level case.

 Note: After case is in position, it must be

sealed to floor to prevent entry or leakage

of liquid or moisture.

Note: Illustration shown may not

exactly reflect every feature or

option of your particular unit.

INSTALLATION, CONT’D: FRONT GLASS ALIGNMENT & ADJUSTMENT (VIA RAIL SYSTEM)

Case with Curved

Front Glass

7. Front Glass Alignment & Adjustment via Rail System (For Curved and Flat Front Glass)

 Proper alignment of the front glass is important to create and maintain a seal inside the case.

 Improper alignment can cause air leaks compromising the environment inside the case and create condensation.

 Follow the five steps listed below to assure proper front glass alignment.

 Illustrations shown may not exactly reflect every feature or option of your particular case.

2. Front-to-Back Leveling:

 Place a level on top of case,

perpendicular to the front glass.

 Raise or lower either side of case

by shimming under the rails

(following steps 3 & 4 below).

 Double-check the side-to-side level.

1. Side-to-Side Leveling: Place a level on top of display case (parallel

to front glass). Raise or lower either side of case by inserting shims

under the rails to level the case (following steps 3 and 4 below).

5. Verification:

 After inserting shims, open and shut the front glass.

 Verify (again) that the front glass is properly aligned at

both left-hand and right-hand side of the case.

 If not, repeat the shimming procedure until the front

glass is properly aligned along both sides of the case.

8. Field Wiring Box / LED Driver / Raceway / LED Driver /

Anti-Condensate Axial Fans

 Probe leads are in probe leads box (on certain models).

It is located at customer front-left of case (behind front panel).

 Field wiring box is also located at case front)

 LED driver and terminal strip is also located behind front electrical cover (shown removed for illustrative

purposes).

 Screws hold front electrical cover in place. Unscrew and drop electrical cover down and out.

 Anti-condensate axial fans (for front glass) may be accessed (at underside of front panel) by simply

removing four screws, and dropping fans down.

 Caution! Only certified electricians are to access electrical components!

 Cases have drains at left and right hand sides.

 Longer cases may have drain at case center.

 Drain field connection location as shown.

 See next page for illustration of TXV Valve,

Drains, Refrigeration Line Stub-Ups Access, etc.

 Depending upon drain access needs, either front

or rear panel may be removed to gain access to

drain stub-up.

 1.5” male PVC stub-up connection is under case.

 Drain stub-up may be at case center in extended

length cases.

 Connect tub drain to floor drain. Maintain

1/4” fall per foot to provide proper drainage.
