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 specific UL certification 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.
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 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.
