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.
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. Failure to do so
can result in an explosion, death, injury and
property damage.
Brazing must not begin before all propane has
been cleared from the immediate area, the in-
side 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 procedures in place. The safety proce-
dure must comply with all applicable codes
such as local fire department's codes.
At minimum, the following actions are re-
quired:
• 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.
