Case ventilation openings must be
clear of any obstructions. Do not
damage the refrigerant circuit.
Always disconnect the electrical
power at the main disconnect
when servicing or replacing any
electrical component. This in-
cludes, but is not limited to, such
items as fans, heaters, thermostats and
lights.
Do not use mechanical devices
or other means to accelerate the
defrosting process.
Do not use electrical appliances
inside the food storage
compartments of the case(s).
Excessive ambient conditions may
cause condensation and therefore
sweating of doors. Facility operators
should monitor doors and oor
conditions to ensure safety of per-
sons.
This warning does not mean that Hussmann products
will cause cancer or reproductive harm, or is in
violation of any product-safety standards or
requirements. As clarified by the California State
government, Proposition 65 can be considered more of
a‘right to know’ law than a pure product safetylaw.
When used as designed, Hussmann believes that our
products are notharmful. We provide the Proposition
65 warning to stay in compliance with California State
law. It is your responsibility to provide accurate
Proposition 65 warning labels to your customers when
necessary. For more information on Proposition 65,
please visit the California State government website.

UL LISTING
These merchandisers are manufactured to
meet ANSI/ UL 471 standard requirements
for safety. Proper installation is required to
maintain the listing.
FEDERAL / STATE REGULATION
These merchandisers at the time they are
manufactured, meet all federal and state/
provincial regulations. Proper installation
is required to ensure these standards are
maintained. Near the serial plate, each
merchandiser carries a label identifying the
environment for which the merchandiser was
designed for use.
In compliance with DOE 2017, standard low
temp Reach In cases with Innovator I Doors
are equipped with an anti-sweat controller that
maintains the door heat at a level that meets
DOE energy limits. Any factory or eld-installed
anti-sweat controller applied to a low temp
Reach In case with Innovator I Doors must be
programmed to cycle the heaters at no more
than 50% run time at design conditions of
75degrees, 55% RH for frozen food operating
condition.

FREEDOM LINE DESCRIPTION
These cases are designed to be ready for
remote installation of a top-mounted air-
cooled or water-cooled condensing unit. They
are controlled by an electronic control. The
case temperature is controlled by cycling
the compressor based on the discharge air
temperature input. The sensor for this input
is located above the interior top panel at the
right door. Another sensor, located on the
bottom center evaporator coil return bend, is
used for defrost termination. The controller is
programmed for low or medium temperature
operation, and is adjusted for the required
temperature by the keypad located on the front
of the controller, which is on the top of the
case.
Cases running on individual condensing units
may be installed as stand-alone cases with ends,
or as a part of a lineup. When installed in a
lineup, Hussmann recommends that partitions
be installed between individual cases to prevent
frost buildup and other issues that might result
from different defrost schedules and operating
temperatures.
LOCATION
These merchandisers are designed for
displaying products in air conditioned stores
where temperature is maintained at or below
the ANSI/NSF-7 specied level and relative
humidity is maintained at or below 55%.
Placing refrigerated merchandisers in direct
sunlight, near hot tables or near other heat
sources could impair their efciency. Like
other merchandisers, these are sensitive to
air disturbances. Air currents passing around
merchandisers will seriously impair their
operation. Do NOT allow air conditioning,
electric fans, open doors or windows, etc. to
create air currents around the merchandisers.
