Supra-Pulse FJH Series

Cartridge Dust Collector

Revised 02/02

When multiple module solenoid valve enclosures with

heaters are installed, daisy chain the wiring so that each

heater will have 100/115/VAC, 50/60Hz at all times. Make

certain enough current is available to supply all heaters.

Example: If three solenoid valve enclosures are

supplied with cartridge heaters, make certain the

voltage supply can deliver 3 amps (1 amp per heater).

5. OPERATION

5.1 START UP

Inspect the installation area and make certain no tools,

parts, etc. have been left anywhere on or inside the FJH

unit. Check blower discharge to make certain it is free

from all debris.

Start motor/blower and check for proper rotation. A

rotation arrow is located on the blower housing. All top-

mount blower assemblies rotate in a clockwise rotation

as viewed from the driven end (motor end with motor

cooling fan). If the blower is rotating in the opposite

direction, disconnect the power to the motor starter. For

3-phase blowers, interchange any two power wires to

the motor at the load side of the motor starter contactor.

For single-phase power, refer to motor nameplate for

which two wires to interchange at motor junction box.

Engage starter disconnect, start blower and recheck

rotation.

NOTE: Proper blower rotation is required to move the

designed amount of air. A blower rotating in the

incorrect direction will only move about 40% of

design airflow.

NOTE: It is important that the air volume of the dust

collection system is at design conditions at

system start-up. There is a minimal pressure

differential across new cartridge filters. If the

volume control damper is not correctly

adjusted, the air volume will be above design

conditions for airflow and may affect the

cartridge filter life.

The air volume should be adjusted based on the

performance of the entire system. Air volume control

damper should be adjusted to the system design

conditions. Closing the volume damper decreases

system airflow. Opening the volume damper increases

system airflow.

On certain applications, it may be beneficial to “seed” or

pre-coat the original or replacement cartridge filters.

This process introduces a certain amount of coating

(usually crushed limestone, agricultural lime or other

specifically marketed pre-coat) in light concentration to

deposit a thin coating of material which acts as an aid to

filtration. This deposited dust cake keeps the dust

loading on the surface of the cartridge filter. This

process will increase filter life and efficiency while

allowing the cleaning system to work more effectively.

For filter seeding procedures, refer to Section 6.2.

Turn on the compressed air supply to the dust collector

air manifold reservoir. Adjust the pressure regulator until

the gauge reads 90-110PSIG (6.2-7.6BAR).

CAUTION

Shut off unit disconnect and lock out all electrical

power to the dust collector prior to performing

service work.

CAUTION

Prior to unit start-up, all installation set-up instructions

must be completed as specified by this manual,

, as well as any

manuals supplied by other equipment manufacturers,

as they apply to your dust collector.

CAUTION

The blower assembly provided by United Air

Specialist, Inc. includes an outlet damper. If the blower

assembly was purchased separately, ensure a volume

control damper is included somewhere in the dust

collection system. Close the blower discharge damper

to 50% open position and tighten in place. If a volume

control damper is provided in another part of the dust

collection system, adjust second damper to the 50%

open position and tighten in place.

CAUTION

Verify dust collector system airflow is adjusted to

design conditions with new, clean filters using the

volume control dampers installed in the system.

Failure to properly adjust system airflow may affect

cartridge filter life.
