General
CAUTION
These instructions are of the utmost importance in
assuring that the Manitowoc Koolaire cabinet
operates as designed, and must be followed closely.
Positioning the Cabinet
CAUTION
When selecting a permanent location for the
cabinet, observe the following guidelines. Failure to
do so may cause reduced performance and
efficiency, cause damage, and void your warranty.
Heat of Rejection
CABINET LOCATION GUIDELINES
• Install the cabinet in an indoor environment only.
• The air temperature entering the refrigerator or
freezer condenser should be between 55°F (13°C)
and 100°F (38°C).
• Allow space for air circulation in the refrigeration
condensing unit compartment on refrigerators and
freezers. The minimum space requirements are:
• 10” (25 cm) on top
• 4” (10 cm) at the back
• 4” (10 cm) on each side
• The floor must be strong enough to support the
weight of the cabinet and product load.
CAUTION
A fully loaded reach-in cabinet can weigh more
than 3,000 pounds.
All refrigeration equipment rejects heat through the condenser. It is helpful to know the amount of heat rejected,
to determine the additional load that will be placed on air conditioning equipment.
