Ambient Temperatures
High ambient temperatures and high humidity
•
conditions may result in performance issues
and/or refrigeration system failure.
These products are indoor rated products and
•
should never be exposed to direct weather.
Do not subject the product to direct solar load.
•
•
This equipment is not intended to be installed
directly adjacent to a heat source.
•
Under extreme temperature and/or relative
humidity conditions, the front face, gasket and
glass door may show signs of condensation.
When the temperature and/or relative humidity
conditions return to normal, condensation will
disappear.
6.2.1 Freezer Ambient Conditions
For units installed in areas with changing ambient
conditions, please take note of the table below. In
extreme conditions that exceed those listed below,
condensation may start to form on the front face of
the cabinet.
Condensation will subside as conditions return to
levels below those shown in the table.

Air Flow Obstructions
The unit must have free air flow to the
•
front grill and to the evaporator intake and
discharge openings to operate properly.
Restricted air flow results in high head
pressures and reduction in efficiency due to
longer run times. Proper air flow through the
condenser and evaporator is necessary for
efficient operation.
•
Never obstruct air flow in and out of the
machine compartment. The front grill must be
free from obstructions, dust and debris. See
Figure 6-4.1 and 6-4.2.
Never obstruct the evaporator intake openings
•
or the discharge louvers or openings. Avoid
placing bagged or solid items at intake or
discharge openings. See Figure 6-5.1. and
6-5.2
Make sure higher temperature ambient air from
•
another unit is not directed to the condenser
coil (i.e. another heat source adjacent to or
directly across from the unit).
