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

OVERVIEW

 These Structural Concepts self-service cases are

designed to merchandise packaged products at 41 °F (5 °C) or less product temperatures (unless custom cases with wire rack shelving).

 Cases should be installed and operated according to

this operating manual’s instructions to insure proper performance. Improper use will void warranty.

TYPE I vs. TYPE II ENVIRONMENTAL CONDITIONS

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

 Type I display refrigerators are intended for use in an

area where environmental conditions are controlled and maintained so that the ambient temperature does not exceed 75 °F (24 °C) and 55% maximum humidity.

 Type II display refrigerators are intended for use in an

area where environmental conditions are controlled

and maintained so that the ambient temperature does not exceed 80 °F (27 °C) and 60% maximum humidity.

 If unsure if your unit is Type I or II, 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

 Following are important warnings to prevent injury or

death.

 Please read carefully!  See next page for PRECAUTIONS.

COMPLIANCE

This equipment MUST be installed in compliance with

all applicable NEC, federal, state and local

electrical and plumbing codes.

WARNING

Risk of electric shock. Disconnect power before servicing unit.

CAUTION! More than one source of electrical supply is

employed with units that have separate circuits.

Disconnect ALL ELECTRICAL SOURCES before servicing.

WARNING

Hazardous moving parts. Do not operate unit with covers removed.

Fan blades may be exposed when deck panel is removed.

Disconnect power before removing deck panel.

WARNING

Condenser Pan is Hot!

Disconnect and allow to cool

before cleaning or removing from case.

PRECAUTIONS

 Following are important precautions to prevent

damage to unit or merchandise.

 Please read carefully!  See previous page for specifics on OVERVIEW, NSF

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.

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.

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! 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 or small rooms increase noise level. Whisper

Cool compressor blankets or remote units resolve noise level issues.

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

(self-contained units only).

CAUTION! CHECK CONDENSATE PAN POSITION AND PLUG

Water on flooring can cause extensive damage!

 Condensate pan MUST BE positioned directly under

Before powering up unit, check the following:

condensate drain.

 Condensate pan plug MUST BE securely plugged into

receptacle.

INSTALLATION: REMOVAL FROM SKID (LEVELERS AND RAILS vs. CASTERS)

1. Remove Case From Skid (Levelers and Rails)

 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.

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

Slide Skid Out

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.

Roll down ramp and off from skid.

Note: Illustrations shown

OPTIONAL NIGHT AIR CURTAIN INST. & OPERATING (MODELS HV(L)RSS, HMO(L)36R, HMO(L)53R)

Night Air Curtain Installation & Operating Instructions

1. Use caution when handling Night Air Curtain.

2. Display case may come with Night Curtain already attached. If not, a retrofit kit will be provided. If using SCC-supplied retrofit kit, attach to display case by centering night curtain along top-front of case as shown in illustration below. Attachment Magnets will hold Night Air Curtain firmly in place. To attach to display case, place night curtain on top of case as shown. Mark “key slot” locations using night curtain as a template (you may have to retract the curtain from housing to reveal “keyslots”. Drill Ø11/32” holes in top board 1/2” deep. Press “finserts” (shown below) into holes. Carefully tap in with flat object to prevent top board damage. Attach Night Air Curtain with #10-32 screws.

3. Grasp the handle and pull downward to desired location INSIDE

4. To return Night Air Curtain to its retracted position, grasp handle, lift up and away from its magnetic attachment and carefully wind Night Air Curtain back into roll.

5. Caution! Doing so can eventually destroy Night Air Curtain’s tension and retractability.

6. To entirely detach Night Air Curtain from case, retract curtain (to access keyslots), remove screws. Lift Night Air Curtain upward and away from case.

Do not allow spring-loaded Night Air Curtain to freely snap back into roll.
