LOCATION
These merchandisers are designed for displaying
products in air conditioned stores where
temperature is maintained at or below the
ANSI/ NSF-7 specified 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 efficiency. 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.

INSTALLATION
PRODUCT TEMPERATURES
Product should always be maintained at proper
temperature. This means that from the time the
product is received, through storage, preparation
and display, the temperature of the product
must be controlled to maximize product life
This equipment uses a flammable
refrigerant. Installation, service and
repair should be done only by qualified
and trained technicians in accordance
with this manual.
If a leak is detected, follow store safety proce-
dures. It is the store's responsibility to have a
written safety procedure in place. The safety
procedure must comply with all applicable
codes such as local fire department's codes. At
minimum, the following actions are required:
• Immediately evacuate all persons from the
store, and contact the local fire department to
advise them that a propane leak has occurred.
• Call Hussmann and/or a qualified service
agent and inform them that a propane sensor
has detected the presence of propane.
• Do not let any persons back into the store
until the qualified service technician has
arrived and that technician advises that it is
safe to return to the store.
• The propane gas used in the unit has no
odor. The lack of smell does not indicate a
lack of escaped gas.
• A hand-held propane leak detector
("sniffer") should be used before any repair
and/or maintenance is attempted. All repair
parts must be identical models to the ones
they are replacing.
• No open flames, cigarettes or other possible
sources of ignition should be used inside the
building where the units are located until
the qualified service technician and/or local
fire department determines that all propane
has been cleared from the area and from the
refrigeration systems.
