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 .
