This manual contains important instructions for installing, using, and servicing a Merchandiser Freezer case. A parts
list is included with this manual. Read all these documents carefully before installing or servicing your equipment.
STORE CONDITIONS
The Merchandiser Freezer 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 Merchandiser Freezer cases 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.
