Donaldson Dust Collector TG 4

⚠ WARNING: 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.

⚠ CAUTION: Do not climb on door, door frame, retention parts, or filter components. Use care when servicing the filters as there are rotating parts.

Turn power off to collector and bleed manifold pressure to 0 psi.

Open access door by turning handles counterclockwise and swinging door fully open.

Rotate each assembly counterclockwise to decompress filters.

Detach right-side arms and rotate them up, then reinstall locking pins to hold arms in place.

Detach left-side arms and let them rotate down and out of the way.

Open cradles fully to access filters.

Sprinkler systems place a large quantity of water in the dust collector when activated. Provide adequate drainage to remove water to avoid personal injury or property damage

Fire control sprinklers are available for all models operating under negative pressure. Donaldson Torit supplied sprinklers require a minimum of 15-psig water pressure. The volume of water discharged per sprinkler head is 17 gallons per minute

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

1. Remove or open the filter access covers 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 sprinkler assembly onto the 1-in diameter sprinkler tap

Warning: Ensure the power supply is OFF before starting the procedure

1. Monitor the physical condition of the collector and repair or replace any damaged components.

- Routine inspections will minimize downtime and maintain optimum collector performance.

- Periodically check the compressed air components and replace compressed air filters.

- Drain moisture following the manufacturer’s instructions. With the compressed air supply ON, check the cleaning valves, solenoid valves, and tubing for leaks. Replace as necessary.

2. Monitor pressure drop across filters.

- Abnormal changes in pressure drop indicate a change in operating conditions and possibly a fault to be corrected.

- For example, prolonged lack of compressed air will cause an excess build-up of dust on the filters resulting in increased pressure drop.

- Cleaning off-line with no flow usually restores the filters to normal pressure drop.

Use proper safety and protective equipment when emptying dust container

Dust containers may be heavier than they appear

Use care when removing dust container to avoid personal injury

To reduce the risk of damage from fires or explosions, combustible dust should not be stored in the collector

Remove accumulated dust from the collector at least once per day and at more frequent intervals if conditions warrant

Use extreme caution when removing combustible materials. Avoid creating dust clouds and ensure no materials are burning prior to servicing the dust container
