PRE-INSTALLATION PROCEDURES
Inspection for Shipping Damage
You are responsible for filing all freight claims with the delivering truck line. Inspect all cartons
and crates for damage as soon as they arrive. If damage is noted to shipping crates or cartons or if
a shortage is found, note this on the bill of lading (all copies) prior to signing.
If damage is discovered when the case is uncrated, immediately call the delivering truck line and
follow up the call with a written report indicating concealed damage to your shipment. Ask for an
immediate inspection of your concealed damage item. Crating material must be retained to show
the inspector from the truck line.
INSTALLATION INSTRUCTIONS
Locating the Display Case
The case should be located where it is not subjected to the direct rays of the sun, heating ducts,
grills, radiator, or ceiling fans, nor should it be located near open doors or main door entrances.
Also, avoid locations where there is excessive air movement or air disturbances.
The condenser air inlet is located at the rear of the case. Do not block this inlet and do not located
the air inlet near a source of heat.
Removing Case from Shipping Skid
Move the case as near as possible to the final location before removing it from the shipping skid.
Remove the four (4) bolts that secure the case to the skid. Do not remove the shipping brackets
from the case. The brackets are intended to be used as hand grips for locating the case. Remove the
brackets when the case is in the final location
CAUTION: Do not push against the curved glass, end glass, doors, or door frames when removing
the case from the skid or moving the case.
Case damage or glass breakage could result.

Series ’90 Cold Deli Display Page 6
Removing Packaging Material
Remove the brackets that held the case to the shipping skid.
Remove the plastic ties that hold the metal shelf and shelf brackets in place.
Remove the shipping tape that secures the doors and lift-up glass. If it is necessary to remove tape
residue from plastic materials, use cleaning compounds recommended in the cleaning section of this
manual.
Leveling the Case
The case must be level for proper drainage of defrost condensate to the condensate evaporator.
Four (4) leg levelers are provided for leveling the case. The leg levelers can be turned in and the
case can be placed with the base frame on the floor.
The leveled case can be sealed to the floor using an NSF Listed Sealant.
Grill Removal
The front of the case has a removable base panel to access the anti-fogging fans and the front leg
levelers from inside of the case. Normally it is not necessary to remove the panel to install the case.
This panel must be in place for proper operation of the case.
There are two (2) removable panels on the back of the case. The left side panel allows access to the
light ballasts, the pullout condensing unit, and the field wiring connection box. Remove this panel
to make field wiring connections.
The right side panel houses the thermometer, power switch, light switch, and thermostat.
Removing this panel allows access to the terminal board, branch circuit fuse (SN8CD Only), and
the condensate evaporator. Normally it is not necessary to remove this panel to install the case.
Condensate Evaporator
This case is furnished with an electric condensate evaporator. Plumbing connections are not
required.
The condensate evaporator is located behind the control panel box and is accessible from the rear
of the case.
Lights
Make certain that the light cord plugs are completely inserted into the sockets or arcing may result
causing damage to the plugs and sockets.
The ballasts used on this case allow removal of one or more shelf lights without affecting the
remaining lights.
DANGER: Electric shock hazard. Do not operate unit with panels
removed.

Series ’90 Cold Deli Display Page 7
Shelving
Remove both rear doors from the track by lifting them upward until the bottom edge clears the
lower door track and then outward. Lift up the front glass to the fully open position. Put the shelf
support assembly in the desired shelf standard slots.
Plug the shelf light cords in the appropriate light socket. Make certain that the light cords are
completely inserted into the sockets or arcing may result causing damage to the plugs and sockets.
Put the metal shelf on the rear shelf support assembly as shown. If the shelf is not in the proper
position, it may disrupt the air flow in the case and cause product loss.
Close the front glass and reinstall both rear doors.
Display Component Check
The display case power switch is located on the control panel at the back of the case. After the case
is properly wired to the power source, the switch should be moved to the “on” position to check the
case components. The switch should be turned off any time the case is not in operation.
The case is equipped with a top light and shelf light. The light switch is on the control panel at the
back of the case. The switch should be moved to the “on” position to verify that the lights are
working properly. The lights should be turned off any time the case is not in operation.
The refrigeration system temperature control is on the control panel at the back of the case. The
temperature control knob should be moved to a numbered position to verify that the refrigeration
system functions properly. The temperature control knob should be in the “off” position when the
case is not in use.

ELECTRICAL INFORMATION &
GROUNDING
This Case Must Be Grounded
All case electrical connections must be performed only by a licensed electrician.
All electrical wiring hookups must be done in accordance with all applicable local, regional, or
national electrical standards.
A separate circuit for each display case is recommended to prevent other appliances on the same
circuit from overloading the circuit and causing malfunction.
The electrical service must be grounded upon installation.
This unit is designed for permanent connection to a power source. See the electrical data plate
located at the rear of the case for proper circuit size and wire ampacity.
Connect a separate 115 Volt, 60 HZ, 1 Phase power supply to the display case junction box and a
separate 115 Volt, 60 HZ, 1 Phase power supply to the appliance receptacle junction box.
The electrical connection boxes are accessible from the rear of the case. See diagram below for
location of the field wiring connection boxes.
DANGER: Improper or faulty hookup of electrical components in the
display case can result in severe injury or death.

OPERATING INSTRUCTIONS
Initial Start-Up
After all the checks outlined in the installation section of this manual have been made, the case is
ready to be put into service.
Controls
Light Switch
This switch controls power to the entire case. The switch rocker is red in the “on” position, black in
the “off” position.
Power Switch
The power switch controls power to the entire case. The switch rocker is red in the “on” position,
black in the “off” position.
Temperature Control
This controls the case temperature by cycling the compressor/condensing unit. It has an off
position and numbered positions 1 through 9. Set this control at the smallest number while
maintaining desired case temperature.
Thermometer
This a solar powered device. It updates the temperature display approximately every 10 seconds.
Doors
The doors can be removed by lifting the door up until the bottom clears the bottom tracks. Clean
the door frequently for easy door operation. A very light film of lubricant, such as PAM, will help
the doors slide easily.
Anti-Fogging Fans
Two fans are mounted in the base of the unit to blow warm air from the refrigeration system over
the curved glass to prevent fogging.
The warm air is vented through the slots in the glass handle. Do not block these vents or the front
glass will fog. These fans run continuously when the power switch is on.

Series ’90 Cold Deli Display Page 10
Hinged Front Glass
The front glass hinges up for easy cleaning of the case interior. Pneumatic cylinders assist in lifting
the glass. The glass will hold in any position beyond approximately the first 20” of travel. In the
first 20” of travel, the glass will gently close. See diagram below:
The hinged glass mechanism will give years of reliable operation in normal usage. Service on the
lift mechanism is required if…
-The glass becomes difficult to open.
-The glass does not hold in the open position.
-The glass closes fast.
Consult the factory if service is required.
CAUTION: OPERATION OF THE LIFT-UP GLASS IS TO BE
DONE BY TRAINED PERSONNEL ONLY. THIS CASE
IS NOT INTENDED TO BE USED AS A SELF-
SERVICE UNIT. DO NOT ALLOW CUSTOMERS TO
OPERATE LIFT-UP GLASS.
