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 2” 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 Install this 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: 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 an 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
The case comes standard with one led top light and two led vertical lights that are wired into the case. The light switch is located on the top ceiling.

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.
The ERSSHPSC cases are designed to operate at 38º to 40º 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 38º F. or colder 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.
Digital Display
This unit is equipped with a CAREL 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 38º F. 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 performance and excessive sweating.
