Portions of your Torit baghouse, including the clean and dirty chambers of the baghouse, may be considered "OSHA Permit Required Confined Spaces." OSHA Regulations, found in the Code of Federal Regulations, 29 CFR Section 1910.146 control the entry of "confined spaces." Please refer to this regulation to determine if your use of the baghouse requires a permit program. Methods of determining "acceptable entry conditions" vary depending upon the application and the type of dust collected. In some cases, a visual inspection of airborne dust in the baghouse may be sufficient. In other cases, chemical tests may be necessary to insure safe entry and occupancy. Torit recommends that employers follow safe work practices during installation and use of all dust collection equipment. This includes following applicable OSHA regulations and any other applicable local, state, or federal laws. Copies of OSHA Regulations can be obtained from your local OSHA office or:

1.0 Introduction
1.1 Operational Explanation
The Torit HPH, HPT, and HPW are used for the collection of airborne dust and particulate. As part of a manufacturing process, the HP collector series provides highly efficient, continuous, on-line dust collection.
Standard HP models are available in sizes ranging from 36 to 320 filter tubes. Other sizes are available as specials. The standard filter length is 8 feet. The HPH is a low profile horizontal filter removal collector; the HPT is a vertical filter removal collector; and the HPW is a vertical filter removal collector with a walk-in top section.
If, after reading this manual, you have further questions or are in need of technical or field support, contact your local Torit representative.
1.1.1 Normal Operation (See Figure 2)
During normal operation, dust-laden air enters the HP inlet section next to the filter tubes. The airflow must turn 90° to pass through the filter tube section. The energy loss from turning and the reduced velocity in the inlet section causes the heavier dust particles to drop directly into the hopper below. A standard inlet baffle helps evenly distribute the dust-laden air around the filter tubes. The dust is collected on the outside surface of each filter tube where it forms a cake that aids in filtering efficiency. Filtered (clean) air passes through each filter tube into the clean air plenum where it is discharged through the clean air outlet.

1.1.2 Filter Cleaning
Filter tubes are cleaned automatically and sequentially. Only one row of filter tubes is cleaned per pulse. During the filter tube cleaning purge, the solid-state timer energizes a solenoid valve. This action causes the corresponding diaphragm valve to send a pulse of compressed air out into the blowpipe. The blowpipe is equipped with two high pressure nozzles centered over each oval shaped filter tube. The high pressure pulse enters the inside of the filter tube forcing air through the filter. The collected contaminants are blown away from the outside surface of the filters. The dust falls into the hopper where it is discharged into drums, screw conveyor, or rotary valve.
2.0 Installation
2.1 Inspection
The collector is normally shipped with major components preassembled when possible. However, due to space restrictions and/or to minimize freight costs, some components may be shipped unassembled and nested. On most HPW/T models, the clean air plenum, dirty air plenum, and hopper/support weldment are unassembled.
A crane is recommended for unloading, assembly, and installation of the dust collector. Before unloading major components, such as housing and hopper, check inside for smaller items that could be damaged if not removed first. Unload components in a location that allows for parts identification and assembly. The filter tubes should be stored in a dry, rodent-proof area until ready for installation.
2.2 Ship Loose Items
Items shipped loose with the HP dust collector may include:
Hopper
Legs and Cross Bracing
55-Gallon Drum Cover Pack
Transition Pack
Magnehelic Gage or Photohelic Gage
Control Box
Hardware/Sealant
Explosion Vent

2.4 Preinstallation (See Figure 1)
The HP dust collector is usually mounted on a reinforced concrete foundation. However, roof mounting is also possible. When calculating for foundation or roof mounting, the weight of both the dust collector, the material being collected, and all auxiliary equipment must be considered together with wind, seismic and other live loads. See the Specification Control Drawing for the dust collector weight.
CAUTION
Location must be clear of all obstructions such as utility lines or roof overhang (see Specification Control Drawing).
NOTE
Wearing safety equipment such as helmets and glasses is recommended for all persons while working in or around the collector.
CAUTION
Use appropriate lifting equipment and adopt all the safety precautions needed for moving and handling the equipment.
A crane must be used to move the collector into position.
To avoid delay, install foundation in the proper location. Pay particular attention to the anchor bolt location. Anchor bolts must extend at least 1-3/4" above foundation. The collector should be located with consideration for emptying hopper storage area, shortest runs of inlet and outlet ductwork, electrical and compressed air connections, and convenience of maintenance. In case of hazardous dust collection, consult with local authorities for the proper location of the dust collector.

2.5 Assembly of Standard Equipment (See Figure 1)
CAUTION
A crane is recommended for the unloading, assembly, and installation of the dust collector.
Connect lifting sling to a minimum of 4 lifting lugs. Distribute loads equally. Use clevices, not hooks, on lifting sling. Use spreader bars on lifting sling.
2.5.1 General Safety Precautions
1. Be certain that the crane has sufficient capacity to lift sections, sub-assemblies and complete units, if that applies. Check weights and dimensions of dust collector components on specification drawings furnished by Torit. Spreader bars are recommended between lifting cables; shallow cable angles should be avoided.
2. No person shall operate the crane or other erection equipment except those qualified by training and experience.
3. Do not install during gusty or heavy winds.
Remove all crating and strapping from the unit. Remove all miscellaneous parts (bolts, nuts, etc.) before lifting unit off of the truck. Check the parts received against the packing slips. If there are parts missing, the carrier and your local Torit Representative should be notified immediately.
NOTE
Each item to be attached to your collector is accompanied by a drawing that shows the attachment process. Refer to both the drawing and this manual when erecting your collector.
4. Note location of adjacent structures, power lines, traffic, unstable ground, and ground obstacles in the erection area.
5. Never swing loads over personnel.
6. Use conventional hand signals for crane operators.
7. Always consider electrical lines to be live (hot).
8. Provide an observer to assist crane operator for periods of impaired visibility.
9. Refer to applicable OSHA regulations and local rules in using cranes, forklifts, and other erection equipment.
10. Make liberal use of drift pins to align holes in section flanges during assembly.
11. Wear appropriate safety gear including hard hats and safety glasses.

2.5.2 Erection (Major Collector Components)
HPT/W Units Only - (Hopper & Legs)
CAUTION
Do not disconnect crane until the lifted component is securely fastened in place.
The following general procedure is recommended for assembly:
NOTE
If the dust collector is shipped preassembled, including support legs, it may be lifted directly from the truck onto the foundation.
If the dust collector is shipped unassembled, see Specification Control Drawing for correct orientation and location of components.
1. The HPT/HPW hopper/leg arrangements come totally assembled.
2. Lift the hopper/leg assembly, using a crane, into position over the anchor bolts and lower down onto the anchor bolt pads. Fasten the legs to the anchor bolts with washers and nuts (provided by customer). Level the hopper at the top flange in all directions by placing solid steel shims under the leg pads. Tighten the nuts on the anchor bolts. Re­check level and adjust as required. Remove the crane from the hopper.
3. Apply 1/4" diameter sealant to the top flange all around toward the inside edge of the bolt pattern (see Figure 5, Sealing Details).
All flanged connections of components providing air seals, including clean air plenum, tube section, and hopper, must be sealed before assembly with sealant as shown in Figure 5, Sealing Details unless they are factory assembled.
Use spreader bars for lifting sections of collector.
Use drift pins to align holes during erection.
Filter tubes and cages can be installed before or after collector is erected.

HPH Units Only - (Hopper & Legs) (See Figures 3 and 4)
1. HPH units have unassembled leg sets. Locate and identify all legs, bracing, and hardware required for leg set. Organize the legs and bracing for assembly.
2. Lift the hopper using a crane and position over the four legs. Stand each leg up on its pad, one at a time, and position the hopper gusset holes to line up with the holes in the leg. Use a drift pin to assist in hole alignment. Fasten each leg using the proper bolts, washers, and nuts provided. Do not
tighten any hardware at this time. Do not disconnect the crane.
3. Position the inside angle of the cross bracing and bolt in place using the proper bolts, washers, and nuts provided. Do not tighten.
Position the outside angle of the cross bracing and bolt in position. Where the two angles cross, bolt through each hole with a bolt, washers, and nut. Repeat this sequence on the opposite side of the hopper. Do not
tighten hardware.
4. Lift the hopper leg assembly into position over the anchor bolts and lower down onto the anchor bolt pads. Fasten the legs to the anchor bolts with washers and nuts (provided by customer). Level the hopper at the top flange in all directions by placing solid steel shims under the leg pads. Tighten all hardware on the gussets, cross bracing, and anchor bolts. Re-check level and adjust as required. Remove the crane from the hopper.
5. Apply 1/4" diameter sealant to the top flange all around toward the inside edge of the bolt pattern (see Figure 5, Sealing Details).

2.5.3 Filter Tube Installation (See Figure 6)
Several filter medias are available to meet the filtration needs for many different types of dust. Contact your local Torit representative for assistance in choosing the correct media for your dust collection requirements.
The cages will arrive on site packaged in crates. The filters will arrive on site packaged in boxes. Choose a clean area for pre-assembly of the filters onto the cages.
Installing the filters before the filter section is raised will be easier and save time. Install the filter tubes as shown in Figure 6, Filter Tube Installation. Slip the filter tube over the filter tube frame until it touches the top flange of the
Donaldson Company, Inc. © 1995
frame. Slide this filter assembly through the tubesheet. Align the two bolts with the threaded inserts in the tubesheet. Secure each filter tube and frame assembly with the Boltsafe™ hardware provided.
NOTE
Use a speed wrench to tighten the screws. Do not use a power driver or impact nut driver. These may strip threads or shear screws.
Only tighten screws until the top flange rests on the tubesheet, about 8-10 ft. lbs torque.
