11. Airlock:
The system is designed with an
airlock to remove material from
the air flow. It is located under
the receiver tank and the
collected material drops into an
airlock compartment as it turns.
As the rotor turns and a com-
partment moves from its up
position to its down position, the
material in the rotor compart-
ment will fall out.
12. Airlock Unplugging:
If a large piece of debris is
drawn into the intake, it can get
into the airlock, stall it and have
to be removed. To unplug, lock
out tag out master panel and
remove obstruction through the
access door on the receiver
tank. Rotate airlock by hand
after obstruction is removed to
be sure airlock turns freely and
has not been damaged. Repair
airlock if damaged before
resuming work.
13. Lock Out Tag Out Procedure:
It is recommended that the
customer institute a formal
lock out tag out procedure
for their workplace. In simple
terms, this policy would
require every person that will
be servicing, adjusting,
maintaining or unplugging
the system to lock out the master panel
and place a tag on it before working on the
unit. Only the person with the tag can
unlock the master switch to allow it to be
turned on. This prevents unauthorized
people from starting up the system and
maintains control by the serviceman
working on the system.
