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 .

•

store, and contact the local fire department to
advise them that a propane leak has occurred .
•

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 .
