Before Beginning Any Service or Repair:
Use a hand-held propane leak detector (“sniffer”)
to ensure no propane is present in the immediate
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. Failure
to do so can result in an explosion, death, injury
and property damage. Parts used on hydrocarbon
cases must meet specic UL certication for non-
incendive or non-sparking components. 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.
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.
If a leak is detected, follow store safety
procedures. 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 re department’s codes.
At minimum, the following actions are required:
• Immediately evacuate all persons from the
store, and contact the local re department to
advise them that a propane leak has occurred.
• Call Hussmann and/or a qualied 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 qualied 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
qualied service technician and/or local re
department determines that all propane has been
cleared from the area and from the refrigeration
systems.
