Donaldson Donaldson Cartridge Dust Collector DWS 6-1 DWS 6-1

Filter Removal and Installation

Use proper safety and protective equipment when removing contaminants and filters.

Dirty filters may be heavier than they appear.

Use care when removing filters to avoid personal injury.

Note: Remove filter cartridges by opening the top and bottom doors. Start with the top filters first. Optional plastic filter bags are offered for filter and dustpan dust removal for cleanliness.

1. Turn the knob counterclockwise until it is loose. Remove the knob and access cover.

2. Remove the filter cartridge from the yoke.

Warning: Electrical work must be performed by a qualified electrician and comply with all applicable national and local codes.

Turn power off and lock out electrical power sources before performing service or maintenance work.

Do not install in classified hazardous atmospheres without an enclosure rated for the application.

Control panel mounted in a convenient, accessible location

Tubing connected to the low-pressure barbed fitting on the control panel and to the barb fittings on the rear of the power module marked Low

Upload a photo of the control panel wired to the motor and solenoid valves

Blower motor turned on and off for rotation check

To reverse rotation with a three-phase power supply: Turn electrical power off at the source and switch any two leads on the output side of the blower-motor starter.

Instruct all personnel on safe use and maintenance procedures.

Use proper equipment and adopt all safety precautions needed for servicing equipment. Electrical service or maintenance work must be performed by a qualified electrician and comply with all applicable national and local codes.

Turn power off and lock out electrical power sources before performing service or maintenance work.

Do not install in classified hazardous atmospheres without an enclosure rated for the application.

Turn compressed air supply off and bleed lines before performing service or maintenance work.

Do not set compressed-air pressure above 50 psig. Component damage can occur.

All compressed air components must be sized to meet the maximum system requirements of 60 psig supply pressure.

The compressed-air supply must be oil and moisture free. Contamination in the compressed air used to clean filters will result in poor cleaning, cleaning valve failure, or poor collector performance.

Purge compressed air lines to remove debris before connecting to the unit’s compressed air manifold.

Sprinkler systems place a large quantity of water in the dust collector when activated. Provide adequate drainage to remove water. Excess water weight can cause the leg structure to collapse.

Optional fire control sprinklers are available for all models operating under negative pressure. Donaldson Torit supplied sprinklers require a minimum of 15 psig water pressure to each module. The volume of water discharged per sprinkler head is 20 gallons per minute.

Consult with local authorities when installing fire control systems on dust collection equipment.

1. Open the front access doors to access the sprinkler tap located in the dirty-air plenum.

2. Apply pipe sealant to the threads of the pipe reducer located on the sprinkler assembly.

3. Thread the sprinkler assembly onto the 1-inch diameter sprinkler tap.
