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 locate 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 eight (8) screws that secure the case to the skid.
Market Deli Refrigerated Cases Page 3
CAUTION: Do not push against the curved glass, end glass, doors, or
doorframes when removing the case from the skid or moving
the case. Case damage or glass breakage could result.

Removing Packaging Material
Remove the brackets that held the case to the shipping skid.
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 and NSF Listed Sealant.
Grill Removal
The front of the case has a removable base panel to access the refrigeration
components. 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 is one (1) removable panel on the back of the case. The panel allows access to
the condensing unit, and the field wiring connection box. Remove this panel to make
field-wiring connections.
Condensate Evaporator
This case is furnished with an electric condensate evaporator. Plumbing
connections are not required.
The condensate evaporator is located behind the rear panel and is accessible from
the rear of the case.
Make sure that the drain line has not been dislodged during shipment and that the
drain terminates properly over the water reservoir.
Lights
The ballasts used on this case allow removal of one or more top lights without
affecting the remaining lights.

DANGER: Electrical shock hazard. Do not operate unit with
panels removed.

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 next to electrical junction box for proper circuit size and wire
ampacity.
The electrical field connection 2 x 4 box is accessible from the rear of the case and is
located in the right “leg” (as viewed from case rear). A second 2 x 4 field connection
box is also located in the right leg and is required to supply electrical power to the
general purpose receptacle.

DANGER: Improper or faulty hookup of electrical components in
the display case can result in serve 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.
Doors
Clean the door track frequently for easy door operation. A very light film of lubricant,
such as PAM, will help the doors slide easily.
The entire door track assembly may be removed if desired by tilting the top back and
lifting the entire frame out.
The display case is intended to be operated with the rear doors in place. However,
during peak service periods, the doors may be removed for ease of serving out of case.
DO NOT keep doors off unit for long periods of time.
Light Replacement
Remove bulb from top light assembly by rotating bulb 90 degrees and pulling outward.
This will allow bulb prongs to easily slide out of bulb receptacles located at each end of
the bulb.
The bulbs are furnished with plastic safety light shields. Make certain the light shields
are always in place to safeguard against bulb breakage.
When replacing lights, use direct equivalents to the original bulbs.
Placing Product into Case
Do not block the slots along the front or rear of the case display floor.
CASE SHOULD BE STOCKED WITH PRE-CHILLED PRODUCT ONLY.
The display pans are removable for cleaning and can become dislodged in shipment.
To ensure proper airflow and performance of the case, make sure that the display pans
are positioned as shown. Check that the pans are installed properly before placing
product on the display pans.
