INSTALLATION INSTRUCTIONS

Locating the Display Case
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 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.

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.

Remove the front and rear compressor compartment grills.
Three or Four bolts secure the case to the shipping skid.

Remove, then discard these bolts.

Leveling the Case

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

evaporator or floor drain.
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.

Grill Removal

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

The front and rear grills require removal for case installation.

Both grills must be in place for proper operation of the case. Grills must be reinstalled
after case installation.

Condensate Evaporator

NOTICE: During normal defrost cycles, steam from the condensate

evaporator may be visible around the case.

This case maybe furnished with an electric condensate evaporator.

Plumbing connections may not be 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.

Lights

The case comes standard with one top light and two vertical lights that are wired into
the case. The light switch is located in the control compartment behind the lift up
access door in the base front left corner.
