Before Beginning Any Service or Repair:
Use a hand-held propane leak detector (“sniffer”)
to ensure no propane is present in the immedi-
ate area, the inside of the display case and the
inside of the refrigeration system. R-290 is an
odorless refrigerant. Keep the area clear of all
customers and non-essential or unauthorized
personnel.
Verify that all repair parts are identical models
to the ones they are replacing. Do not substitute
parts such as motors, switches, relays, heaters,
compressors, power supplies or solenoids. Fail-
ure to do so can result in an explosion, death,
injury and property damage. Parts used on
hydrocarbon cases must meet specific UL certifi-
cation for non-incendive or non-sparking com-
ponents. Use only Hussmann approved parts
approved through the Hussmann Performance
Parts Website.

Brazing must not begin before all propane has
been cleared from the immediate area — the
inside of the displays case and the inside of the
refrigeration system.
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 occured.
• 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 re-
turn 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 de-
partment determines that all propane has been
cleared from the area and from the refrigeration
systems.
Only Hussmann or factory
trained technicians should
service or repair this R-290
(propane) equipment.
Failure to follow
instructions can result in
an explosion, death, injury
and property damage.
