4.
BEFORE INTRODUCING ANY DUST TO THE COLLECTOR, TURN THE POWER OFF
TO THE CONTROL PANEL.
5.
Start the fan with the fan damper or duct blast gates partially open. At the
same time observe the differential pressure of the control. This gauge indicates
the pressure drop across the dust cake and fabric. Rising pressure on the
gauge shows that dust is being collected on the bag. When the gauge shows 1”
to 3” w.g., the fan damper or duct blast gates may be opened to the full
normal position. Simultaneously, the power should be turned on to the control
panel.

Normal operation
The primary function of the AR ArrestAll dust collector is to move air, and
thus create suction and remove the dust from the air. As a dust cake develops on
the fabric surface of the filter, differential pressure will rise and airflow will be
reduced. The unit must be shaken with sufficient frequency to preclude significant
loss of suction.
Frequency of the dust removal from the bin should be determined from
experience and an appropriate maintenance cycle established. Because of the
intensity of shaking, it is imperative that the door be properly latched to prevent
leakage.
With the hand-off-auto switch, the frequency of shaking can be controlled by
the owner. It is recommended that shaking be minimized to extend the life of the
filter cartridge and mechanical components. This is especially pertinent to
installations where the unit might be turned on and off numerous times during the
day, such as a school woodworking shop. In the “AUTO” position, the unit shakes
every time the unit is turned off. In the “OFF” position, shaking can be actuated
anytime the switch is pushed toward the “HAND” position. The fan must always be
turned off before shaking.
The duration of the shaking process is adjustable from 0.6 to 60 seconds
(recommended time set at approximately 15-20 seconds) with an initial fan coast
delay which is adjustable from 0.6 to 20 seconds (recommended time factory set
at 20 seconds).
For cold weather applications, it is especially important to allow the collector
to operate for an extended period of time before shaking.
