Associated Equipment 73-250 - Manual (Page 2)

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.
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.
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.
