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 upon arrival. If there is damage to
shipping crates, cartons, or if a shortage is found, note this on (all copies) of
the Bill Of Lading 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 and shown to 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, radiators, or ceiling fans, nor should it be located near open doors
or main door entrances. 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.

The condenser air inlet is located in the front of the case. Do not block this inlet and do
not locate the air inlet near a source of heat. Clearance of 6” minimum must be
maintained at the back of the case for condenser discharge air. Clearance at the top of
the case should also be at least 8”.

Do not build this unit into an alcove and do not locate where condenser discharge air
cannot escape or where warm condenser air is allowed to re-circulate.

Grill Removal

NOTE: This case is designed for indoor use only.

WARNING

is secured with fast lead captive screws, and the rear base grill is secured with self
threading screws.

Both base grills must be replaced after merchandiser installation. Base grills must be
in place for proper operation of the merchandiser.

Refrigerated Self-Serve Merchandiser (High Profile) Page 3

Must remove front and rear base grills for merchandiser installation. The front base grill

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

Removing Case From Shipping Skid

the case is lifted under the welded steel frame, and not by the end panels of the case.
Damage to the ends will result from lifting under the end panels.

CAUTION: If a Johnson bar or pry bar is used to move the case, make certain that

Move the case as near as possible to the final location before removing it from the
shipping skid. Having removed the front and rear compressor compartment grills. Remove
the (three or four sets of bolts, nuts, and washers depending on case size) that secure the
case to the shipping skid. Discard these bolts, nuts, and washers.

Removing Packaging Material

Remove bubble wrap and packing material for all shelves, etc. If it is
necessary to remove tape residue from various materials, use cleaning
compounds recommended in the cleaning section of this manual.

Leveling the Case

evaporator or condensate pump.
Check the level of the case along the front rail and along the top of the display pan.

Shim under the case frame as needed to level the case. It is recommended that the
leveled case be sealed to the floor with an NSF Listed Sealant.

The case must be level for proper drainage of defrost water to the condensate

Condensate Evaporator

base of the merchandiser during normal operation.

electric condensate pump. Plumbing connections are not required, unless
merchandiser is specifically ordered without a condensate evaporator or pump.

The condensate evaporator can be removed from the merchandiser and the
condensate drain can be plumbed to a external drain to conserve energy. To remove
the condensate evaporator, disconnect the wires at the condensate evaporator. This
must be done by a qualified electrician.

This is an open merchandiser and can produce a large amount of condensate water.
To ensure that adequate evaporator capacity is available, a high wattage heater is
used.

Make sure that the condensate drain line has not been dislodged during shipment and
that the drain trap terminates properly over the water reservoir.

Lights

Standard Top Light
The case comes with one standard top light which is internally wired to the power

source. The light switch is located in the top light housing under the top canopy.

Optional Shelf Lights
If optional shelf lights are furnished, make certain that the shelf light cords are

completely inserted into the sockets in the back panel or arcing may result, causing
damage to the plugs and sockets.

The ballasts used on this case allow removal of one or more shelf lights without
affecting the remaining lights.

When plugging or unplugging light cords, turn the light switch to the “off” position.

ELECTRICAL CONNECTION AND
GROUNDING INSTRUCTIONS

Electrical Supply Wiring
DANGER:

display case can result in severe injury or death.

Permanent Connection (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 at the rear of the case for circuit load and wire current capacity.

-Standard Base Electrical Connection: The electrical connection box is accessible from the rear of the
case. Power Supply Wiring can be routed through the floor of the base frame or through the access hole
in the rear of the unit. Remove electrical box cover to access electrical connections.

Improper or faulty hookup of electrical components in the

Cord Connection (Optional)

-A factory installed optional power cord is properly sized to the amperage requirements of the
merchandiser. See the electrical data plate located on the ceiling of the merchandiser for the proper
power requirements for each merchandiser.

- The cord is factory installed protruding from the rear of the merchandiser.

-A separate circuit for each display merchandiser is required to prevent other appliances on the same

circuit from overloading the circuit and causing a power loss.

depending on case environment.

Alarm light

This light indicates that there is a problem with case or electronic control and
service should be called.

Refrigerated Self-Serve Merchandiser (High Profile) Page 8

Initial Start-Up

After completing the items in the installation section of this manual. The case is ready
to be put into service. On self-contained models, the service valves on the refrigeration
system are back-seated when the unit leaves the factory.

RSSM cases are designed to operate at 40º to 41º F. under ambient conditions not to
exceed 75º F. and 55% relative humidity.

Nearly all open refrigerated merchandisers operate better when loaded with product
than when empty. If a check is made of the case operating temperatures, perform this
check with product in the case.

Open refrigerated merchandisers are not intended as storage refrigerators and will not
“pull down” room temperature products efficiently. Load case interior with pre-chilled
product only.

Light Switch And Lights

The light switch is located in the top light housing, under the canopy. This switch
operates the interior lights only. If optional shelf lights are installed, they are also
controlled by this switch.

Light Replacement

The light fixtures use a spring-loaded socket on one end. To remove a light, push the
bulb toward the spring-loaded socket until the opposite end drops out of the socket.

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.

Digital Display

This unit is equipped with an Invensys – Ranco model E72R temperature control with
Digital Display. The Display shows discharge air temperature (not shelf temperature).

Placing Product In Case

Do not overload the case with product to a point where the top air discharge grill or the
bottom air intake grill are blocked, or where the air curtain created by the discharge air
is blocked.

LOAD CASE INTERIOR WITH PRE-CHILLED PRODUCT ONLY.
