SERVICE
Disconnect electrical power before servicing.
Shut off and bleed compressed air supply before servicing any compressed
air components.
No welding should be performed inside without fire protection.
Avoid contact or exposure to dust during servicing or maintenance.
Dust removal
Do not let the dustbin overfill. It can cause poor dust collector performance.
1. Turn off the dust collector and empty the dust disposal on a regular base
(recommended to empty the dustbin when 3/4 full).
2. If the hopper has a butterfly valve, close before servicing the dust bin. Remove
and empty the bin.
3. Reinstall the bin and open the valve. The fan does not has to be shut off if this
procedure is followed.

(see figure 25 - Exchanging filter cartridge)
Filter cartridge removal
All filter cartridges should be changed at the same time.
Dust laden filters may be heavy and difficult to handle. Provide appropriate
means of access to replace filter cartridges safely in case no platform is
installed.
Generally filter cartridges cannot be washed and re-used. Only non-cellulose
based media types can in some instances be cleaned with water, but contact
your Donaldson Torit representative before doing so.
1. Turn off power to the collector.
2. Begin filter cartridge replacement at one of the top filter access ports. Continue
by replacing the remaining filter cartridges in the top row. Proceed to replace
filter cartridges in the next rows. Replacing filter cartridges 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.
The genuine Donaldson Torit filter cartridge is the only replacement filter that
will provide the high level of performance that you expect from your investment
in the Donaldson Torit dust collector.
