Caution!Application of Dust Control Equipment

• Combustible materials such as buffing lint, paper, wood, aluminum or steel dust, weldfume, or flammable solvents represent fire or explosion hazards. Use special care whenselecting and operating all dust or fume collection equipment when combustiblematerials are present to protect workers and property from damage due to fire and/orexplosion. Consult and comply with National and Local Codes relating to fire orexplosion and all other appropriate codes when determining the location and operationof dust or fume collection equipment.

• When combustible materials are present, consult with an installer of fire extinguishingsystems familiar with these types of fire hazards and local fire codes forrecommendations and installation of fire extinguishing and explosion protectionsystems. Donaldson dust collection equipment is not equipped with fire extinguishingor explosion protection systems.

• DO NOT allow sparks, cigarettes or other burning objects to enter the hood or duct ofany dust or fume control equipment as these may initiate a fire or explosion.

• For optimum collector performance, use only Donaldson replacement parts.

Warning – Improper operation of a dust control system may contribute to conditions in thework area or facility that could result in severe personal injury and product or propertydamage. Check that all collection equipment is properly selected and sized for the intended use.

Description

The Unimaster series dust collectors are self-contained, intermittent-duty dust collectors withbag-style filters. Three standard configurations—UMA-B, UMA-H, and UMA-D provide effectivecleaning in a variety of industrial settings.

Most popular is Model UMA-B and ships completewith fan, easy-access filter assembly, multiple-inlethopper and dust bin with quick-release sealer gear.Model UMA-H is a control unit with fan and filterassembly only. The housing has an open bottomand flanges to bolt directly to a dust container orhopper. Model UMA-D includes a fan, easy-accessfilter assembly, multi-inlet hopper and drum coverassembly to fit a standard 55-gallon drum.

Standard sizes range from 43 to 753 sq ft of filterarea and features a UMA controller to control thefilter cleaning operation. Other options includeacoustic diffusers, explosion relief vents, staticgrounding, weather hoods and caster frames.

Purpose and Intended Use

The Unimaster dust collectors are used to separatesolid particulate from an airstream as part of amanufacturing process. It is an ideal choice forintermittent operations in plant processes. Severalsmall units can be installed at dust generation sitesthroughout the plant resulting in total dust captureand flexibility. Some typical installations includeblending/mixing, abrasive blasting, cleaning,cutting, drilling, grinding, milling, packing,polishing, sanding, and sawing.

Caution!

• Misuse or modification of this equipmentmay result in personal injury.

• Do not misuse or modify.

Operation

During normal operation, dust-laden air enters theunit through the dirty-air inlet. The velocity isreduced and natural pre-separation, caused by theeffects of gravity, takes place and heavierparticulate falls directly into the collection bin orhopper. Fine particles collect on the outside surfaceof the filter bag and clean, filtered air passes to thecenter of the bag and discharges through the clean-air outlet.

The Unimaster is an intermittent-duty collector,which means that cleaning starts when the fan isturned OFF and the appropriate fan run-down timeis complete. The solid-state timer automaticallystarts the cleaning sequence 75-seconds after thefan is turned OFF. This is the fan run-down time.Power to controls must remain ON to operate thecleaning mechanism. The vibration motor startsand filter cleaning begins for a preset time of 30-seconds.

Note: Do not mount the controller on the unit.Mechanical vibration can damage thecontrol.

2. Using the wiring diagram supplied with thecontroller, connect the power lead from acustomer-supplied disconnect switch to theterminal block inside the controller, complyingwith all applicable codes for motor branchcircuits.

Note: The national electric code requires allconnections to the electrical enclosure beof the same rating.

3. Install conduit from the controller to thejunction box located on the side of the collector.Use conduit and fittings compatible with therating of the controller’s enclosure.

4. Make the connections from the manual motorprotector inside the controller to the terminalblock in the junction box.

UMA Controller

The UMA Controllers are used with three-phase,50- or 60-Hz power supplies or optional single-phase power, and suitable for fan motors rated toand including 30 horsepower.

Operation

Start

• Press START button.

- Fan contactor M1 is energized, timermodule sets, and the fan motor starts.Average operating period for fan is 4hours.

Clean

• Press CLEAN button.

- Fan contactor M1 is de-energized andthe timer is energized.

- After approximately 75-seconds, theshaker motor contactor M2 is energizedand the shaker motor runs forapproximately 30-seconds.

- Shaker motor contactor is de-energizedand the timer resumes inactive status.

Note: Before a cleaning cycle can startby pressing the CLEAN button, theM1 fan contactor must have beenenergized for at least 30-seconds.

In the event of a power supply failure during acycle, an internal safety feature ensures thecontroller automatically resets ready for the fan tobe restarted. Reapplying power does not requirethe cycle to be completed.

Caution!

• Personal injury, death, or propertydamage can result from materialdischarge during venting.

• The material discharged from anenclosure during the venting of anexplosion should be directed safely toan outside location.

• The risk of damage or injury can beminimized or avoided by locatingvented equipment outside buildings andaway from normally occupied areas.

• Standard explosion vents are intendedfor outdoor installations only.

• Explosion relief vents must be safely directedoutdoors away from personnel, buildings,property, offices, walkways, and catwalks toreduce risk of damage to property and personalinjury. Explosion venting calculations are basedon formulas from NFPA-68, 1998 for outdoorapplications only, with no duct or obstructionson the explosion vent panel.

• Explosion vents are suitable for negativepressure installations only.

• Contact Donaldson for assistance in calculatingsafe and specific venting requirements for Toritequipment.

Caution!

• Do not look into fan outlet todetermine rotation.

• Check that the exhaust plenum is freeof tools or debris before checkingblower/fan rotation.

• Stand clear of exhaust to avoidpersonal injury.

Preliminary Start-Up Check

1. Check all electrical connections for tightnessand contact.

2. Check for and remove all loose items in or nearthe inlet and outlet of the unit.

3. Check that all remote controls are wired intothe control system, and all service switches arein the OFF position.

4. Check that all optional accessories are installedproperly and secure.

5. Check that hopper discharge is open and thestorage container is sealed, if equipped. Excessairflow to the blower will cause electricalfailure.

6. Turn power ON at source.

7. Turn the fan motor ON then OFF to check forproper rotation by referencing the rotationarrow located on the motor’s mounting plate.

To reverse rotation, single-phase power supply:

Follow manufacturer’s instructions on themotor’s nameplate.

To reverse rotation, three-phase power supply:

Turn electrical power OFF at source and switchany two leads on the output-side of the fan-motor starter.

Caution!

• Lock out electrical power sourcesbefore service or maintenance work isperformed.

Start-Up

Press the Start button on the controller panel tostart the unit.

Shut-Down

1. Press the Clean button on the controller.

2. The fan stops when fan run-down cycle iscomplete.

3. The cleaning cycle starts and when finished, theunit turns OFF.

Service Information

Operational Checklist

1. Monitor overall performance of the collector.

2. Monitor exhaust.

3. Monitor pressure drop across filters.

4. Monitor dust disposal.

Check Weekly

1. Pressure drop across filters range from 1 to 6 “wg.

2. Inspect explosion relief vent, if equipped, fordamage, snow, or ice.

Check Monthly

1. Door seals for condition and contact. Replaceor adjust as necessary.

2. Check that the clean-air chamber is free of dustaccumulation. If dust is present, check thesurrounding filter bags for tears or loose seals.

3. Check rubber seals for tears and overcompression.

4. Check that the shaker mechanism bolts aretight and secure. Check for diaphragm wear ordamage, broken locators on the shaker bar, ortorn shaker-bar support straps. Replace asnecessary.
