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 NOTE: This case is designed for indoor use only.

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

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

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

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 7

Removing Case From Shipping Skid

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

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.

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

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

Condensate Evaporator

NOTICE: Steam from the condensate evaporator may be visible around the

base of the merchandiser during normal operation.

This merchandiser may be furnished with an electric condensate evaporator, or a

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 on the left top ceiling behind the air discharge honey comb.

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 and end of led lights or lights will not work

The power supply used on this case allows for 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: Improper or faulty hookup of electrical components in the

display case can result in severe injury or death.

THIS CASE MUST BE GROUNDED

Optional Permanent Connection

-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.

OPERATING INSTRUCTIONS

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.

-RSSL 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 ceiling. This switch operates the interior lights only. If optional

shelf lights are installed, they are also controlled by this switch.

Led Light Replacement

The light is attached to the shelf with plastic spring clips. To remove a light, un plug cord from

end of bulb and pull down.

When replacing lights, use direct equivalents to the original bulbs.

Digital Display

This unit is equipped with an electronic temperature control with Digital Display.

The Display show a number 1 thru 9 to indicate temperature level.

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 38deg OR COLDER

PRODUCT ONLY.

Energy Saving Night Curtain

This unit is equipped with an energy saving night curtain.

The night curtain is located in the top inside front of the canopy.

To use the night-curtain pull down and latch on front panel just below the

clear acrylic air deflector when case is not in use.

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
