Do not drop or rap the new filter cartridge on the floor or any other hard surface.
Damage to the filter cartridge will occur, resulting in leakage. It is necessary to
clean the dust off of the tube sheet all around the opening to ensure a positive
seal of the filter gasket.
4. Break the seal between the filter cartridge and the sealing surface.
5. Slide each filter cartridge out the access port along the suspension yoke and
dispose of properly.
6. Inspect and clean the sealing surface if necessary.
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.
If the gasket is damaged the cover has to be replaced.
Lack of compression of the filter gaskets can cause leakage.
Filter cartridge 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 (
∆
)
at the top of the filter endcap (non-gasketed end) must match with the
alignment mark (
∇
) at the top of the filter access opening.
2. Inspect cover gaskets. Clean and/or replace as necessary.
3. After new filter catridges have been installed, place the access cover on the yoke
and hold it in position while tightening the knob securely by hand (3 turns) before
using tool assist option.
4. If knob fails to thread onto yoke, on the opposite side of the hinge, apply slight
pressure to the access cover using other hand. Continue to turn knob to start
threading onto the yoke.
The access cover must be properly aligned to ensure a dust tight seal to the
housing.
Do not exceed 17 N*m (150 inch*lb) tightening torque to secure access
cover as over tightening may cause damage to the filter and/or equipment.
After securing the access cover check that access cover is properly seated
and sealed against the collector cabinet front panel (a.k.a. access panel).
If access cover is properly seated it will seal correctly with no more than
150 in*lb tightening torque.
