INTRODUCTION

This manual contains im portant instruc tions for ins talling, using, and servicing a M erchandiser Refrigerato r case. A
parts list is included with this manual. Read all these documents carefully before installing or servicing your
equipment.

STORE CONDITIONS

The Merchan diser Refrigerator cases are designed to operate in the controlled environment of an air-conditioned
store. The store temperature should be at or below +75°F and a relative humidity of 55% or less. At higher
temperature or humidity conditions, the performance of these cases may be affected and the capacity diminished.

The M erchandiser Refrig erator should not be positioned where it is directly exposed to rays of sun or near a direct
source of radiant heat or airflow. This will adversely affect the case and will result in poor performance.

If this case is to be located against a wall, there should be at least 4” space between the wall and the back of the
case. This space will allow for the circulation of air behind the case, which will prevent condensation on the exterior
surfaces.

NOTICE

doing any service on the equipment. Failure to do so could result in personal injury or
damage to the cabinet.

DANGER

Improper or faulty h o o k-up of electrical components on the refrigeration units can result
in severe injury or death.

All electrical wiring hook-ups must be done in accordance with all applicable local, regional or
national standards.

NOTICE

must be performed by a refrigeration mechanic and/or a licensed electrician.

The portions of this m anual covering refrigeration and electrical components contain technical instructions intended
only for persons qualified to perform refrigeration and electrical work.
