1. For proper cleaning, the compressed air pressure
should be regulated at 80 psi maximum.
2. During normal operation the Roto-Pulse
cleaning system is factory set to clean two (2)
cartridge fi lters for a period of .07 seconds every
5 seconds.
3. Once the unit is turned off, the cleaning cycle
will continue for a period of 17 minutes. Do not
service the fi lters until cleaning is completed.
CAUTION: Allow 20 minutes of downtime
before opening fi lter access doors. After-Pulse
system is momentarily operational After unit is
turned off.
4. The Roto-Pulse cleaning operation dislodges
particles from the cartridges. Particles then
fall down into the dust hopper and collection
hopper.
5. After continued use of the unit, the dust
collection barrel will need to be removed and
emptied. The frequency of servicing will vary
depending on the type and quantitiy of dust
that is collected. The dust collection barrel
should be emptied when the barrel reaches half
full (Dependent on weight of material being
collected.)
NOTE: When servicing the collection system, be
sure to turn the unit off.
Roto-Pulse Cleaning Timer
Adjustments
1. Turn unit off via the stop switch and disconnect
power.
2. Remove the electrical box cover.
3. The timer control board is present at the factory
to clean two (2) cartridge fi lters every 5 seconds.
This time can be adjusted from 1 second to 999
seconds. To adjust this time press the select
button on the timer board untill the off time
LED is lit. Press the up/down buttons untill the
desired value is displayed. Press select to set
the new value.
NOTE: Cleaning of the fi lters too often will
decrease your level of performance. A certain
level of dust cake on the fi lters will improve the
effi ciency of the fi lter cartridges. You should try
to maintain a minimum of 1 in w.c. of pressure
differential across the fi lters. If you can not
maintain this minimum level of differential across
the fi lters the time between cleaning pulses should
be increased until this can be achieved.
4. The timer control board is preset at the factory
to have a cleaning pulse duration of .07 seconds.
This can be adjusted from .05 seconds to 600
seconds. the timer board untill the on time
LED is lit. Press the up/down buttons untill the
desired value is displayed. Press select to set
the new value.
NOTE: While this time can be adjusted we
recommend that you leave the “ON TIME” at the
factory setting. If less cleaning is needed you
should increase the time between pulses as means of
reducing the amount of cleaning. If more cleaning
is needed you should decrease the amount of time
between pulses. Beware, as the time between
pulses is decreased for additional cleaning, this
will increase your compressed air consumption and
create an additional load on your compressed air
system.
5. once adjustments have been made replace the
electrical box cover and reconnect the power.
6. Start the unit and observe the new pulse settings
and determine if additional adjustments are
necessary. If more adjusting is needed, repeat
the previous steps.
After-Pulse Cleaning Timer
Adjustments
1. The unit is equipped with an After-Pulse
Cleaning Cycle. This cycle will continue to
clean the cartridge fi lters for a period of time
after the unit is turned off.
2. The length of the After-Pulse operation is preset
at the factory for 999 seconds (17 minutes).
This time can be adjusted from 0 seconds to
999 seconds. To adjust this time press the select
button untill the off time LED is lit. Press and
hold the select button for 3 seconds. Press
the up/down buttons untill the desired value is
displayed. Press select to set the new value.
The after-pulse operation can be disabled by
setting the time value to zero (0) seconds.
