To comply with health codes, heat treatment system
freezers must complete a heat treatment cycle
daily, and must be dis assembled and brush cleaned
a minimum of every 14 days. Brush cleaning is the
normal disassembly and c leaning procedure found in
the Operator Manual. Failure to follow these
guidelines will c ause the control to lock the freezer
out of the AUTO mode.
If the Heat Treatment Cycle fails, the screen will
display a failure message and return the freezer to
the STANDBY mode.
Always comply with local guidelines for the
maximum number of days allowed between brush
clean cycles.
Freezer Locks
There are two t ypes of freezer lock conditions that
can occur: Hard Lock or Soft Lock. A Hard Lock
requires the machine be disassembled and brush
cleaned. A Soft Lock can be c orrected by either
disassembling and brush cleaning the m achine, or
by starting another heat treatment cycle.
Hardlock
There are two causes of a hard lock failure. The
freezer will hardlock if either the Brush Clean Timer
has elapsed or if a Thermistor Failure (Freezing
Cylinder or Hopper) occurred during a Heat cycle.
