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

OVERVIEW

 This merchandiser's upper (service) section consists of

two (2) separate areas:

1. The upper two shelves are AMBIENT
(non-refrigerated) only. It is designed to offer
packaged or unpackaged non-hazardous product.

2. The deck area is convertible. Depending upon baffle

position, this area may be either AMBIENT or
REFRIGERATED. In ambient mode, it is designed to
merchandise packaged or unpackaged,
non-hazardous product. In refrigerated mode, it is
designed to merchandise packaged or unpackaged
hazardous or non-hazardous product at 38 °F (3 °C)
or less temperature.

 The lower (self-service) section is REFRIGERATED

only. It is designed to offer packaged hazardous or non­hazardous product at 38 °F (3 °C) or less temperature.

 Product must be pre-chilled at 38 °F (3 °C) or less prior

to being placed in refrigerated areas of case.

 Cases should be installed and operated according to this

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

NSF® TYPE

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

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

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

 For NSF® Type 2 Conditions: ambient conditions are to

be at 60% maximum humidity and maximum
temperatures of 80 °F (27 °C).

 If unsure if unit is NSF® Type 1 or 2, 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 page contains important warnings to prevent

injury or death.

 Please read carefully!

OVERVIEW / NSF® TYPE / COMPLIANCE / WARNINGS / PRECAUTIONS / WIRING - PAGE 2 of 2

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

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

CAUTION! ADVERSE CONDITIONS / SPACING ISSUES

 Performance issues caused by adverse conditions are NOT covered

by warranty.

 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 will 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 CONDENSATE PAN POSITION & PLUG

Water on flooring can cause extensive damage!

Before powering up unit, check and confirm the following:

 Condensate pan must be DIRECTLY UNDER condensate drain.
 Condensate pan plug must be securely plugged into receptacle.
 Overflow pan must have plug connected to its box. Units with

optional Clean Sweep™ MUST HAVE 2 plugs connected.

INSTALLATION

Installation

: Units shown may not depict an exact representation of your particular unit being installed.

Note

1. Remove Unit From Skid

Caution: case must always remain supported or
center of gravity will allow case to fall. Slide unit to
rear of skid and carefully tip backward off skid.

2. Adjust Levelers

 After case is in proper position, adjust case so it is level

and plumb by adjusting levelers.

 You may need to remove front and/or rear Toe-Kick to

access levelers.

 Adjust levelers with 1” open-end wrench. It may be

necessary to use a Pry Bar to do so.

 Do not use Pry Bar on Toe-Kick.
 Do not use Pry Bar on End Panel.
 Use Pry Bar ONLY on Base Frame to avoid damaging

case.

START-UP AND OPERATION

Merchandiser Start-Up

 Turn main power on. Remove rear grille cover if

installed. Switch is up and under rear raceway on
right side of case.
The Temperature Controller will illuminate.



Coil fans should turn on. From inside of case, check



for discharge air from front baffle, to confirm that
the fans are functioning properly.
When the case is in a start up mode or has been



idle for a long period of time, unit will require 75
minutes to pull-down temperature.
Turn lights on. All lights should come on at the same



time. First time lighting may require a short warm up
period for the bulbs. Slightly dim or a flickering of
new bulbs is normal. If lights do not turn on, check
that all of the light plugs are in. The lighting is wired

in series so all lights must be plugged in or
receptacles capped in order for the case to light.
It is recommended that the self contained



refrigerated cases maintain front airflow clearance of
approximately twelve inches and rear airflow
clearance of approximately six inches.

 Obstruction or restriction of air voids warranty.

The interior case temperature reaches 2 °C / 35 °F



to 5 °C / 41 °F, Note: Case temperature is set at

the factory, as determined by the case size. The
temperature is controlled by a thermostat. If a
temperature setting change is required, refer to the

instructions for the TEMPERATURE
CONTROLLER PROGRAMMING section of this

manual.

Note: Set point should be –8 °C / 18 °F to –7 °C /



20 °F. This will maintain the product temperature
range. Settings lower than this can cause food
items to freeze

Baffles: Ambient vs. Refrigerated

Certain sections of the case can be either
ambient or refrigerated (depending upon type of
product being displayed).

A Dual-Purpose Baffle is provided to facilitate
desired condition. It is accessible through rear
doors.

The Baffle will prevent (or allow) refrigerated air
from circulating through the display area and
returning through the Air Return Grille.

1. For Ambient (Non-Refrigerated) conditions,
Baffle must be positioned to block air flow.
See photo #1 at top right. Note

: Depending
upon model, options and features chosen,
photos may not exactly reflect every aspect
of your particular case.

2. To switch from Ambient to Refrigerated
condition, lift Baffle up and out of air
chamber. Rotate 90 degrees so arrows on
the tag point down and tag is to the rear of
the case. Lower Baffle, with slots facing up,
back down into the air chamber. See photo
#2 at mid-right.

3. For Refrigerated conditions, Baffle is
positioned to allow air to circulate through
display area and return through Air Return
Grille. See photo #3 at lower-right.

 Note: To clean, remove Baffle from case,

brush out crumbs or residue from Baffle.
Wipe down with clean rag dipped in mild
soap and water solution.
