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, 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 damaged 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 and avoid high humidity locations such as near
cases with water misting or fogging devices. Failure to locate this case as stated
will reduce the performance of your Island display and will affect temperature of
interior of case and product.
The case requires a minimum of 48” of clearance is needed on all sides of unit.
Electrical Connection
DANGER: Improper or faulty hookup of electrical components in the
display case can result in severe injury or death.
Permanent Connected (Standard)
-Only a licensed electrician must perform all case electrical connections.
-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 required to prevent other appliances on the
same circuit from overloading the circuit and causing malfunction.
-The electrical service must be grounded upon installation.
-See the electrical data plate located on the base end, for proper circuit size and wire
ampacity.

.Standard Base Electrical Connection: There are (2) different styles of
electrical box connections as shown in pictures below. The electrical connection box is
in the base for floor electrical connection. The box is accessible by removing the base
panel. See “Panel Removal Section” of this manual for panel removal instructions.
Remove electrical box cover to access electrical connection.
Optional Top Electrical Connection: The electrical connection box is
accessible on the top of the case for ceiling drop electrical connection. Remove
electrical box cover to access electrical connection.
Cord Connected (OPTION)
-A factory installed optional power cord is properly sized to the amperage requirements
of the case. See the electrical data plate located on the rear exterior of the case for the
proper circuit size for each case.
- The cord is factory installed protruding from the corner of the case.
-A separate circuit for each display case is required to prevent other appliances on the
same circuit from overloading the circuit and causing malfunction.
CAUTION Risk of Electric Shock. If the cord or plug becomes damaged,
replace only with a cord and plug of the same type".

Condensate Evaporator (Standard 3 Shelf Self Contained Models)
NOTICE: During normal defrost cycles, steam from the condensate
evaporator may be visible around the case.
The standard Self-Contained case is furnished with an electric condensate evaporator.
Plumbing connections are not required.
The condensate evaporator can be removed from the case and the condensate drain
can be plumbed to a drain to conserve energy if desired. Disconnect the condensate
evaporator wires at the condensate evaporator to remove. This must be done by a
qualified electrician.
This is an open merchandiser and at times can produce a large amount of condensate
water. To ensure that adequate evaporator capacity is available, a high wattage heater
is used. The heater turns off automatically when the water level in the pan drops.
Make sure that the drain line has not been dislodged during shipment and that the drain
trap terminates properly over the water reservoir.
Condensate Pump (Standard - Remote & 2 Shelf Self-Contained,
Optional –3 Shelf Self Contained)
NOTICE: This unit could be shipped with an optional condensate pump. The pump has a
float that turns the pump on automatically when needed.
The pump is mounted in the base compartment. The pump should be cleaned and
inspected every 3-4 months.

Powering on control
To turn refrigeration control power on, press and hold for approx. five seconds.
The display will read “On” while the button is depressed. When the control powers on,
the display will read the current set point numbers 1 thru 9. The compressor run
indicator will illuminate on the display, meaning that the compressor is running.
(Note: the control may already be in the on mode when shipped from factory).
To turn refrigeration control power to off, press and hold for approx. five seconds. The
display will read “Off” while the button is depressed. When the control powers off the
display will flash back and forth between the current set point and “Off”. The
compressor run indicator will be off on the display. When refrigeration control is in
the off-mode cabinet lights and evaporator fans will still operate, but the compressor
will not turn on causing the case to gradually reach room temperature.
Adjusting the set point
The set point is what determines how cold the display case will hold food and
beverage. To adjust the set point press and hold the button approx. 5 seconds
until the display begins to flash a number. Then press the use the button to scroll
number up (colder) or press the button to scroll number lower (warmer). There
are nine (9) available set points numbers, the higher the number of the set point, the

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. Turn on the Power at the breaker box and flip the
Power Switch and Light Switch on unit to the on position. At start up from a warm unit, it is
recommended that the temperature control is set at a warm setting, such as After the unit
has gone through several cycles, change the control to a mid-range setting, then to a
colder setting if necessary to maintain desired product temperature
NOTICE: This refrigerated display case is designed to operate
in a maximum environment of 75 DEG. F and 55% relative
humidity. Exceeding these limits will cause poor case
performance and excessive sweating.
Placing Product into Case
-Do not exceed 75 pounds of weight per shelf. Heavy product should be distributed
evenly across the entire shelving area.
- Determine desired shelving location before placing product in case. Product must be
removed to readjust shelf location.
-Allow a minimum of 2” between top of product and bottom of shelf.
-Do not overhang the front or rear of shelves with product. Improper clearance in front
and rear of shelf will block the refrigerated airflow and will cause product loss.
-Do not block the slots along the front and rear air discharge slots. Covering these slots
will block the refrigerated airflow and could cause product loss.
-The display deck is removable for cleaning and can become dislodged in shipment. To
ensure proper airflow and performance of the case, make sure that the display deck is
pushed completely down.
-Allow refrigerated models to run for at least two hours before placing pre-chilled
product into unit.
NOTICE: CASE MUST BE STOCKED WITH PRE-CHILLED PRODUCT
ONLY.
NOTICE: This refrigerated display case is designed to operate
in a maximum environment of 75 DEG. F and 55% relative
humidity. Exceeding these limits will cause poor case
performance and sweating of glass panels.
CLEANING INSTRUCTIONS
Acrylic Air Deflector Cleaning
NOTICE: Clear acrylic air deflector requires special washing procedures
to prevent hazing and yellowing of material.
