WARNING

Process owners/operators have important responsibilities

relating to combustible hazards. Process owners/operators

must determine whether their process creates combustible

dust, fume, or mist. If combustible dust, fumes, or mist is

generated, process owners/operators should at a minimum:

• Comply with all applicable codes and standards.

Among other considerations, current NFPA standards

require owners/operators whose processes involve

potentially combustible materials to have a current

hazard analysis, which can serve as the foundation for

their process hazard mitigation strategies.

• Prevent all ignition sources from entering any dust

collection equipment.

• Design, select, and implement ﬁre and explosion

mitigation, suppression, and isolation strategies that

are appropriate for the risks associated with their

application.

• Develop and implement maintenance work practices to

maintain a safe operating environment, ensuring that

combustible dust, fumes, or mist does no accumulate

within the plant.

Micro Air recommends process owners/operators consult

with experts to ensure all of these responsibilities are met.

As a manufacturer and supplier of Industrial Filtration

Products, Micro Air can assist process owners/operators in

the selection of ﬁltration technologies. However, process

owners/operators retain all responsibility for the suitability

of ﬁre and explosion hazard mitigation, suppression, and

isolation strategies. Micro Air assumes no responsibility

or liabitlity for the suitability of any ﬁre and/or explosion

mitigation strategy, or any items incorporated into a

collector as part of an owner/operator hazard mitigation

strategy.

Improper operation of a dust control system may contribute

to conditions in the work area or facility that could result

in severe personal injury and product or property damage.

Check that all collection equipment is properly selected and

sized for the inteded use.

Always follow the requirements of all authorities having

jurisdiciton (National and Local) in the application,

installation, orperation and servicing of the dust collector.

Many of the processes outlined in this manual will expose

the installer to circuits powered by high voltage. This

installation is recommended for professional electricians or

Micro Air trained factory service personnel. Lock out/ Tag

out procedures are required.

The installation/operation manual must be read and

followed in its entirety.

timer board pressure switch input (HI & COM) and

relay CR1, or the two red wires that are connected to

the timer board pressure switch input (HI & COM)

and the differential pressure switch (HI & LOW). See

speciﬁc unit wiring schematic for further clariﬁcation.

CLEAN AIR SYSTEMS

COMPRESSED AIR INSTALLATION:

The compressed air inlet for the Roto-Pulse cleaning

system is at the top of the surge tank located on the side of

the unit (Figure 15). A minimum of a 3/4 inch diameter

line and clean, dry compressed air at a pressure of 80 psi

to 90 psi is required for proper operation of the Roto-pulse

cleaning system. For models FRP8-3 and FRP8-4 two 3/4

inch diameter lines from a minimum 1 inch diameter header

line are required. A unit speciﬁc combination regulator/

ﬁlter dryer is highly recommended for proper operation.

ELECTRICAL INSTALATION:

Caution: Installation can cause

exposure to live components. Disconnect

electrical power before proceeding with

installation. Proper lock out/tag out

procedures should be used.

PULSE CONTROLS ONLY ELECTRICAL BOX

1. Open the electrical box cover located on the side of the

unit. Make connections from your 120V supply power

to terminal L, N and G (Figure 16).

2. When supply power has been terminated, reconnect

the power. Momentarily turn the motor blower on and

adjust pressure switch via set screw until contact is

made. Use an ohm meter to measure continuity across

the pressure switch.

FULL CONTROL ELECTRICAL BOX

1. Determine the location for mounting the electrical box

(on the unit or remotely). If mounting is on the unit

mount near the pulse jumper box in order to minimize

electrical runs if feasible.

2. Mount the electrical box.

3. Open the electrical box cover located on the side of

the unit. Make connections from your 208V, 230V, or

460V supply power to power distribution terminal L1,

L2, and L3 (Figure 17). Wire size should be rated for

FLA of your application.
