OVERVIEW / TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING / PLUGS - PAGE 1 of 2

OVERVIEW

 These Structural Concepts merchandisers are

designed to merchandise packaged products at 41 °F
[5 °C] or less product temperatures.

 Cases should be installed and operated according to

this operating manual’s instructions to ensure proper
performance.

 Improper use will void warranty.

TYPE 1 vs. TYPE 2 CONDITIONS

This unit is designed for the display of products in ambient
store conditions where temperatures and humidity are
maintained within a specific range.

 For Type 1 Conditions (most cases): ambient

conditions are to be at 55% maximum humidity and
maximum temperatures of 75 °F [24 °C].

 For Type 2 Conditions: ambient conditions are to be

at 60% maximum humidity and maximum
temperatures of 80 °F [27 °C].

This equipment MUST be installed in compliance with

all applicable NEC, federal, state and local

electrical and plumbing codes.

 If unsure if unit is designed for Type 1 or Type 2

conditions, see tag next to serial label. See SERIAL

LABEL LOCATION & INFORMATION LISTED /
TECH INFO & SERVICE section in this manual for
sample serial labels.

COMPLIANCE

 Performance issues when in violation of applicable

NEC, federal, state and local electrical and plumbing
codes are not covered by warranty.

 See below compliance guideline.

WARNINGS

 This sheet contains important warnings to prevent

injury or death.

 Please read carefully!

OVERVIEW / TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING / PLUGS - PAGE 2 of 2

PRECAUTIONS

 This sheet contains important precautions to prevent

damage to unit or merchandise.

 Please read carefully!

 See previous page for specifics on OVERVIEW,

CONDITION TYPE, COMPLIANCE and WARNINGS.

CAUTION! LAMP REPLACEMENT GUIDELINES

LED lamps reflect specific size, shape and overall design.

CAUTION

Any replacements must meet factory specifications.

Fluorescent lamps have been treated to resist breakage and

must be replaced with similarly treated lamps.

CAUTION! GFCI BREAKER USE REQUIREMENT

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.

WIRING DIAGRAM

 Each case has its own wiring diagram folded and in its

own packet.

 Wiring diagram placement may vary; it may be placed

near ballast box, field wiring box, raceway cover, or
other related location.

CAUTION

CAUTION! POWER CORD AND PLUG MAINTENANCE

Risk of electric shock. If cord or plug becomes damaged,

replace only with cord and plug of same type.

CAUTION! ADVERSE CONDITIONS / SPACING ISSUES

 Performance issues caused by adverse conditions are NOT warranted.
 End panels must be tightly joined or kept at least 6-inches away from

any structure to prevent condensation.

 Unit must be kept at least 15-feet from exterior doors, overhead HVAC

vents or any air curtain disruption to maintain proper temperatures.

 Unit must not be exposed to direct sunlight or any heat source

(ovens, fryers, etc.).

 Tile floors/low ceilings/small rooms increase noise level. Whisper Cool

compressor blanket or remote unit may resolve noise level issues.

 Keep at least 8-inch clearance above unit for air discharge

(self-contained units only).

CAUTION! CHECK EVAPORATOR PAN POSITION AND PLUG

Water on flooring can cause extensive damage!

 Evaporator pan MUST BE positioned directly under condensate drain.
 Evaporator pan plug MUST BE securely plugged into receptacle.

Before powering up unit, check the following:

INSTALLATION, CONT’D: REMOVAL FROM SKID / FRAME SUPPORT RAILS / SOUP WELL LAYOUT

1. Remove Case From Skid (Levelers)

 Remove shipping brace that may be

securing case to skid.

 Support case to prevent tipping.
 Caution! Levelers can be damaged if case

hits floor with heavy force!

 Carefully slide unit to

rear of skid and tip

backward off skid.

 Illustration may not

reflect every feature
or option of your

particular case.

Slide Skid Out

Case can be repositioned with pallet truck when
front lower panel is removed. Blocking may be
necessary to obtain adequate height.

2. Frame Support Rails: Shim

 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.
