Ace 73-100 - 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 Vi") inlet plus a
variety of collecting nozzles and fittings, fine solid
particulate material and smoke may be removed from the
air by the filler media
An initial spark trap collects large particles before they
reach the fiter 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
Upon leaving the trap, the air is passed through a one-inch
(r‘) thick, 20 to 35% efficient pre-filter. This pre-filter is
designed to catch the larger particles leaving the trap.
This relatively inexpensive pre-filter prevents the more
expensive mam filter from becoming quickly clogged The
pre-filter should be changed several times before the main
filter needs to be changed. ■
All factory-furnished filters have a U.L. class tl rating
and using any filters other than those specified for
this unit is not recommended.
Use of any product other than that recommended by the
manufacturer will void the warranty
The main (or final) filter may be selected from three (3)
grades available, depending upon the level of
performance desired All of these are high efficiency
multi-flow filters which feature extended surface area for
long life in high velocity filtration systems.
Selection of the filter best suited for the job should be
discussed with a dealer or a factory representative
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
filters should be changed. Depending upon the
application, the pre-filter should be changed several times
before the main filter must be changed Changing the pre­
filters regularly will extend the useful life of the final filter
up to 50%.
GENERAL MAINTENANCE
ONLY QUALIFIED SERVICE TECHNICIANS SHOULD
MAKE REPAIRS TO THIS UNIT.
DO NOT REPLACE THESE MOTORS WITH MOTORS

MANUFACTURER.
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) - Pre-filter
INSTALLATION {See Figure #1)
1
Unpack a main filter and note the main filter has a
1/8" thick black rubber gasket on the outlet end.
Please also note that the filter has an airflow direction
arrow placed on one of the edges Insert the filter,
gasket first, into the machine with the arrow pointing
toward the rear of the unit, away from the inlet end.
Make sure that the filter media folds run vertically If
they do not, remove the filter and rotate it 90'
2. Place the pre-filter directly against the main filter with
the wire supported side toward the main filter and the
media folds again running vertically.
3 Replace the front cover/spark trap assembly and
re-latch the cover using the rubber latches.
4. 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.
5. Attach the hose to the inlet
6. Assemble the flexible metal hose and nozzle per
Figure #2
7 Connect the hose/nozzle combination assembled in
Step 6 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.
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
