All merchandisers are tested, inspected and carefully packaged to ensure each unit arrives ready for
operation. Please return postage paid warranty card to activate merchandiser warranty. (See back page of
manual) Retain for future reference.
Note: Merchandiser should be moved close to an upright position. If merchandiser is tilted 45° past
vertical, it is recommended the unit not be used for a time equal to the time it was not vertical. This
will allow the compressor lubricant to return to level for designed operation.
The merchandiser installation location should have a solid level base. If merchandiser is not level, the self-
closing doors on upright models may not close or seal properly. The installation location must also provide
good air flow for designed refrigeration system operation.
DO NOT
block refrigeration grill openings. Grill
blockage may result in compressor failure.
Outdoor merchandisers: Locations shaded from sunlight are recommended for more economical operation.
Auto-defrost models: Leave sufficient space behind merchandiser to prevent the drain hose from being
kinked or obstructed. A blocked hose will not allow unit cooler condensate water drainage.
Indoor merchandisers: Locations must keep the area above and within full top cover clear from storage
items or from obstructions. As per above, location must provide good air flow for designed refrigeration
system. Auto-defrost glass door models: Remove condensate evaporator carton from inside merchandiser
and install evaporator on back of merchandiser per instruction sheet inside carton. (Screwdriver required)
Optional item installation: Refer to instruction sheet inside carton.
1. Electrical: The electrical voltage and frequency cycle at installation site must coincide with merchandiser
decal serial label. Electrical service connections must be in accordance with the National Electrical Code,
state code and any local code that may apply. All merchandisers are wired to a polarized power cord with
3-prong plug.
CAUTION: Improper use or removal of the grounding plug can result in risk of electrical shock.
