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

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.

needle valve can be adjusted to reduce incoming water pressure to solenoid.
Needle valve is located at inlet of solenoid valve.
Lights
The lights are coated incandescent bulbs and must be replaced with exact
equivalent bulbs. (60 Watt Maximum)
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. Temperature display may not read
accurately with doors off of case. Disregard this temperature reading if doors have
been off unit for extended periods.
Light Replacement
Light bulbs are removed by unscrewing counter clockwise. Install bulbs by screwing in
clockwise. Do not over tighten.
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.
All well cavities must be completely covered with food pans (not included) for proper
operation of case. A variety of sizes of pans can be used from 2” to 6” in depth.

Always preheat the wells before placing product into case. Freshly cooked product
should not be placed into case with a probed temperature of less than 170ºF.
The digital temperature display measures air temperature inside the case. This display
is an indication only. The most accurate method to confirm satisfactory temperatures is
to probe product inside the case.
