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”.

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.

Refrigerated Self-Serve Merchandiser (High Profile) Page 7B

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 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.

Fluorescent 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 a Ranco or CAREL 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 38deg OR COLDER
