1.0 General
The AR ArrestAll® self-contained dust collector is a compact and efficient unit designed to control intermittent, low to medium volume, dry, dust sources. It is cleaned off-line. The unit includes
an air mover and can be relocated as required.
Each collector is furnished with fan assembly, housing, filter cartridge(s), and automatic shaker mechanism for filter cleaning. Based on size, they are available as a bin vent, flat bottom, cart bottom, and funnel bottom arrangements. The size range is from 1,000 to 12,000 ACFM. Read the entire brochure and check each carton and crate against the shipping sheet (AAF Form 1281) before beginning assembly work. DO NOT store the AR ArrestAll
dust collector outdoors.
1.1 Shipment
The AR ArrestAll collector is packaged for domestic transit
and shipped FOB factory. Notify your carrier immediately if there is any damage or discrepancy in the shipping papers.
The AR ArrestAll funnel bottom units are shipped as three major components: the fan, the funnel bottom section, and the cartridge housing section. The bin vent, cart bottom, and the
dust drawer units ship as two major components: the fan and the complete housing assembly. See “Installation Drawing” for proper field assembly.
1.2 Foundations
The foundation must be level and adequate to support the collector ’s operating weight including dust load, discharge devices, wind load if applicable, plus any auxiliary equipment if applicable.
1.3 Space Requirements
Unit location will be determined by system design, space availability, and access requirements. Access to the front of the unit is necessary for dust removal and cartridge replacement. Top access is required for motor, fan, and ancillary component service. Side access is required for shaker motor and control access.
Explosion vents, if furnished, are located on the side opposite the access door. It is recommended that the vent(s) be ducted outside and away from any area containing personnel or equipment. Duct flanges can be match drilled to the collector housing wall, but they must be supported separately from the unit.
1.4 Handling
All units are shipped in an upright position. Lifting lugs are provided on the cartridge section as well as the fan for ease of handling (Figure 1). Spreader bars should be used on the housing. Fork truck handling should be sufficient for the funnel section. Shipping weights are listed in the table in Section 8.0.

2.0 Installation
The AR ArrestAll dust collector is not designed to support inlet and/or outlet ductwork. The duct(s) should be connected to the collector with flexible connections to eliminate vibration transmission.
Close coupling a duct elbow to the collector inlet may result in an uneven velocity profile. This condition could cause previously collected material to be re-entrained. Three to four duct diameters of straight run will give an even airflow distribution at the inlet.

2.1 Anchoring
The AR ArrestAll collector is designed for installation on a
flat surface. Units must be suitably anchored. Anchor holes are provided at the base of the support legs on the funnel bottom units (Figure 2), and anchor clips are provided on the cart bottom (Figure 3). Flat bottom units can be installed by drilling holes in the bottom of the units. Holes drilled in the flat bottom base should be gasketed or caulked to prevent air bypass.
Inlet Transitions
Standard accessories, such as the inlet transition (AR1 only), are shipped loose for field installation with the caulk and attachment hardware provided.
2.2 Field Assembly of Major Components
Funnel Bottom Units
Self-tapping screws and caulk are provided for installation of the funnel bottom section to the cartridge section (Figure 4). Assemblies can be bolted-up from the outside of the unit; interior access is not required. See the field installation drawing for additional detail. The fan is bolted to the top of the unit using the provided hardware. Fan discharge orientation can be varied to suit owner ’s requirements. See the fan installation drawing for additional detail.

Flat and Cart Bottom Units
These units are fully assembled at the factory except for the fan.
Fan discharge orientation can be varied to suit owner ’s requirements. See the fan installation drawing for additional detail.
Bin Vent Units
To prevent possible damage to the unit from ponding water , it is recommended that curbing be used on any bin vent installation (Figure 5).

3. Electrical Installation
All wiring should comply with NEC and applicable local codes.
Refer to the fan installation kit assembly drawing number 3029105 and the wiring diagram furnished with the equipment for proper wiring of the control panel. The major electrical components are the fan motor and automatic shaker motor and control. Factory wiring is standard on all units with the only exception being the fan motor . Use the wiring kit provided to make the final electrical connection
on the unit. See the fan installation drawing for additional detail.
The control should be connected to the power source through a fused disconnect. Check the fan rotation against the rotation arrow for correct motor connections. Fan rotation should always be
clockwise when looking down from the top of the motor.
If incorrect, change the motor leads as indicated on the motor wiring instructions. Provide adequate grounding of the unit.
