SHUTDOWN SEQUENCE OF EVENTS
Once the AMERICAN HARVEST has reached the normal operating temperature and switched to
the “OFF” position, the unit will continue to operate on a much lower setting for 10 minutes.
(Approximately half of the “1” setting). After 10 minutes the auger will slow down further and
continue at this feed rate until the AMERICAN HARVEST “LOW LIMIT SAFTEY” sensor tells the
control board it is safe to shutdown.
Unchanged operation until preset
“OFF” temperature is achieved.
Continues at a lower sequence
Slows down to a “HALF SETTING” for
10 minutes and then to a “QUARTER
SETTING” for the duration of the shut-
down.
Unchanged operation until preset
“OFF” temperature is achieved.
If the American Harvest “HI LIMIT”
sensor snaps open, this will cause an
automatic shutdown. This will be evi-
dent by the green light on the control
board flashing. NOTE: “HI LIMIT” er-
rors are usually the result of operating
at the highest heat setting for long
periods of time, room fan failure or
loose wire connection.
Continues until the operating tempera-
ture falls below 90 degrees. May take
several minutes up to an hour.
Continues until the operating tempera-
ture falls below 90 degrees.
The auger will continue at the lower
feed rates until the operating
temperature falls below 90 degrees.
NOTE: Safety switches, HI limit and
vacuum sensor, must be activated to
continue proper operation.
Will continue to operate until the
AMERICAN HARVEST cools down to
below 90 degrees. This may take sev-
eral minutes up to an hour.
It is rare that the HI LIMIT temperature
is reached. However, should this error
occur, let the AMERICAN HARVEST
cool down for an hour then restart.
