Filter Removal
1. Turn off power to the collector.
2. Begin filter replacement at one of the top filter
access ports. Continue by replacing the remaining
filters in the top row. Proceed to replace filters in the
next rows.
Replacing filters row by row starting at the top will
help limit dusting during replacement.
3. Remove access cover by turning knob
counterclockwise.
Do not use the access cover
features as climbing equipment.
Use safe practices for maintenance and
installation.
Do not drop filters
4. Break the seal between the filter cartridge and the
sealing surface.
5. Slide each filter out the access port along the
suspension yoke and dispose of properly.
6. Inspect and clean the sealing surface if necessary.
Clean dust from gasket sealing
area to ensure a positive filter
gasket seal.
7. Clean any dust from the yoke threads that may have
accumulated during the filter removal.
8. Check for any accumulation of dust in the storage
area and remove as necessary.
Compressed Air Components
1. Periodically check the compressed air components
and replace damaged or worn components as
necessary.
2. Drain moisture following the manufacturer’s
instructions.
3. With the compressed-air supply ON, check the
cleaning valves, solenoid valves, and tubing for
leaks. Repair or replace as necessary.
Dust Disposal
To avoid possible damage to
the fan motor, maintain a seal
below the collector if servicing the dust storage
device while the fan is running.
1. Empty dust container(s) (drum or bin) as necessary to
minimize dust in the hopper.
2. If the optional 55-gallon drum attachment is used,
empty when dust container is 2/3 full.
3. If optional slide gate is used, close gate before
servicing dust container.
Sharp edge of slide gate may
result in personal injury while
closing the slide gate. Keep hands clear when
operating the slide gate.
4. Check integrity of gasket under drum cover.
5. Replace or reinstall dust container and open gate (if
applicable).
Filter Installation
1. Slide the gasket end of each new filter onto the end
of the suspension yoke.
The filter shape and yoke work
together to ensure proper filter
alignment during filter installation. To assist
with alignment, an alignment mark (r) at the
top of the filter endcap (non-gasketed end)
must match with the alignment mark (s) at the
top of the filter access opening.
2. Inspect cover gaskets. Clean and/or replace as
necessary.
3. After new filters have been installed, place the
access cover on the yoke and and hold it in position
while tightening the knob securely by hand (3 turns)
before using tool assist option.
The access cover must be
properly aligned to ensure a dust
tight seal to the housing.
Do not exceed 150 in-lbs (12.5 ft-lbs) torque
when securing the access cover as over
tightening may cause damage to the filter and/
or equipment.
When filter installation is complete, check to
ensure that each access cover is seated and
sealed against the filter housing to ensure a
dust tight housing seal.
