INSTRUCTION & MAINTENANCE MANUAL

CAUTION: This device is powered by rotating electrical machinery!! Careless or improper use may result in

personal injury. Read the Safety Precautions and Warnings contained within prior to operating this machine.

READ AND SAVE THESE INSTRUCTIONS.

SAFETY WARNINGS & CAUTIONS

FAILURE TO OBSERVE THE FOLLOWING
PRECAUTIONS COULD RESULT IN SERIOUS
INJURY, INCLUDING DEATH IN EXTREME
CASES. SAVE THESE INSTRUCTIONS.

WARNING: (EXPLOSION HAZARD)

This unit contains universal motors, which spark

during norma! operation. Do not use in areas
contaminated by volatile or flammable materials as
these sparks may ignite the contaminates and cause

a dangerous explosion.

WARNING: (HARMFUL FUMES)

The filters used in this unitwill remove solid

particulate ONLY, and do not eliminate fumes and
gases that may be a health hazard. Failure to
observe the presence of such fumes could cause
serious illness or death,

CAUTION: (SHOCK HAZARD)

To insure continued protection against shock
hazard, connect AC cord only to properly grounded
outlets. Replace defective cords immediately. Do

not expose to moisture or liquid as this could defeat

the electrical insulation thus causing electrical

shock.

CAUTION: (AIRFLOW BLOCKAGE)

Since exhaust air leaves the bottom of this unit,
caution should be observed not to set unit down in
such a way as to block the exhaust.

MISCELLANEOUS CAUTIONS:

1. Use of any attachment not recommended or
sold by the air cleaner manufacturer may result
in risk of fire, electric shock, or injury to persons.

To reduce the risk of damage to the electric plug

2.

or cord, disconnect by pulling plug rather than
cord when removing power from the air cleaner.

Make sure cord and hose are located so they

3.
will not be stepped on, tripped over, or otherwise

subjected to damage or stress.
An extension cord should not be used unless

4.
absolutely necessary. Use of improper

extension cord could result in risk of fire and
electric shock. If extension cord must be used,

use only a grounded cord and follow these
recommendations:

25 n.-#14AW6.
60 ft. -#12 AWG.

100 ft.-#10AWG.

CAUTION: (STRONG VACUUM)

Care must be taken to avoid personal injury by not
allowing hose inlet to contact any body area such as

eyes, ears, mouth, etc.

CAUTION: (LIFTING)

Although this unit weighs less than 40 lbs. with
filters, improper lifting or handling of this unit could
cause back injury. Follow the recommended

method for lifting.

Do not disassemble the air cleaner. Take it to a

5.
qualified serviceman when service or repair is

required, incorrect reassembly may result in risk
of electric shock or fire.

To reduce the risk of electric shock or bodily

6.
injury, unplug the air cleaner from outiet before

attempting any maintenance or cleaning.
Turning off the power switch will not eliminate

this risk.

THEORY OF OPERATION

This unit is a lightweight, portable air cleaner
employing two thermally protected, high
performance, flow through vacuum motors
producing very high velocity airflow through the unit.
By utilizing a large (2 ’/2") inlet plus a variety of
collecting nozzles and fittings, fine solid particulate

material and smoke may be removed from the air by
the filter media.

An initial spark trap collects large particles before
they reach the fitter. An easy to empty tray is

attached to the front cover to enable the removal of
the large particles collected by the spark trap without
removing the filter. This trap further isolates the filter
from sparks in the case of a welding operation.

A "clogged" filter light, actuated by a differential

pressure switch is an integral part of the unit. When
the filters become clogged, the light will illuminate.
At this point, the filter should be changed.

GENERAL MAINTENANCE

ONLY QUALIFIED SERVICE TECHNICIANS
SHOULD MAKE REPAIRS TO THIS UNIT.

3. Connect the unit to the power source and test
the operation of the unit by turning it ON with the
On/Off switch. Should the motors not start, or

should the machine make unusual noises,
immediately turn the machine off and seek
trained maintenance personnel. Once the test is
complete, turn the unit back OFF.

4. Attach the hose to the inlet.

5. Assemble the flexible metal hose and nozzle per
Figure #2.

6. Connect the hose/nozzle combination
assembled in Step 5 above to the machine with
the 10' flexible hose and the supplied coupling.

This completes the basic assembly of the unit.

Depending upon the accessories ordered and the
logistics of the work place, the installation
configuration may vary.

DO NOT REPLACE THESE MOTORS WITH
MOTORS OTHER THAN THOSE RECOMMENDED

BY THE MANUFACTURER.

UNPACKING

Carefully inspect the unit for concealed damage that

may have occurred during shipping and handling, if
any damage is found, immediately contact the
Freight Company. Make sure there are no dents in
the housing, as they might prevent the filter from
sliding into the unit smoothly. If there is no evidence
of damage, remove the end cover by releasing the
two rubber latches. Removal of the front cover will

allow inspection of the inside of the unit.
After unpacking the machine, check to see that the

following parts and accessories are present:

1) -10' Flexible Hose

1) - Coupling

1) - Flexible Metal Hose/Magnetic Base Component
Parts. (See Figure #2 For Individual Parts
Included)

1) - Slot Nozzle

1) - Filter

INSTALLATION (See Figure #1)

1. Insert the filter, gasket first, into the unit. Then
place the rubber then steel washers over the
threaded rod. Tighten the wing nut down so that
the filter is sealed and will not rotate.

2. Replace the front cover/spark trap assembly and

re-latch the cover using the rubber latches.
