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:
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:

Removing Case From Shipping Skid
CAUTION
: Do not push against the clear acrylic deflector around the sides and nose.
Doing so can cause the acrylic to break.
Do not lift or push on the top canopy located on top of the case.
Doing so can permanently damage the tower frame.
Care must be taken not to damage or tip the case when removing it from the
skid or moving the case.
Remove the screws and brackets that secure the case to the skid. Remove the
brackets from the case.
Note that the case may have optional wheels installed and once the brackets
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.
Adjust the (4) outside leg levelers as needed to level the case in each direction.
The IMSS120 has (2) center leg levelers adjust these so that the center of base
floor is flat.
NOTE: Use a wood or plastic shim under each leg leveler to avoid scratching the
tile floor.

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.
NOTICE: During normal defrost cycles, steam from the condensate
Condensate Pump (Standard Remote, optional 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.
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.
