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

IMSS E3265

holding the case to the skid are removed the case will roll.
Removing Packaging Material
Remove bubble wrap and packing material for all shelves and panel, brackets,
etc. 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 water to the condensate
pump. A wrench is included to aid in adjusting leg levelers
Check the level of the case where the display overhangs the base.

Condensate Evaporator (Standard Self Contained Models)

IMSS E3265
- 12 -
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.
Check that the float is positioned correctly and that the switch operates at time of
installation.
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, optional Self Contained)
Note: There is a piece of cardboard that has to be removed from the side of the
pump to free up the float. If this is not done, the pump will not turn on and the pan
will overflow.
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.

-OFF: Turning the control counterclockwise to the “WARM” setting is an
Off position, this position turns the refrigeration off and all indicator
lights will also be off at this setting.
-ON; The control will be on from the warmest setting at “1” and the coldest
setting at “COLD”.
Cooling light
This light will be on when control requires refrigeration to be on. The
compressor / condensing unit should be running to cool the case.
Defrost light
This light will be on when control when refrigeration is defrosting allowing
ice to melt off of evaporator coil. The number of times and length of
defrost will vary depending on case environment.
Alarm light

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 1 on the dial. After the unit has gone through
several cycles, turn 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.

Maintance
Cleaning Condenser Coil
NOTICE: Condenser coil must be cleaned a minimum of twice per month
to insure proper refrigeration performance and prevent
compressor failure. Failure to clean condenser coil will void
condenser warranty.
It is very important that the Condenser coil is cleaned twice per month to insure proper
refrigeration performance and to prevent compressor failure. Failure to clean condenser
coil will void condenser warranty. This procedure is for Self Contained models. The
remote condenser coil must also be cleaned at same intervals.
1. Disconnect power to the unit.
2. On IMSS60 and IMSS84 Remove the side panel with the narrow set of louvers and on
IMSS120 remove panels from both sides at the end the control panel is located. See the
illustration in the “Bottom Panel Removal” section of this manual for panel clarification.
3. Carefully vacuum the front surface of condenser coil. Take care not to bend coil fins with
vacuum cleaner nozzle.
4. Reinstall side panel(s).
