THEORY OF OPERATION
This unK Is a portable aircieanof employing one tfwmialty pro­
tected, high portofmance motor producing very high velocity
air flow through the unit. Rno soBd partlcutate material and
smoke may be removed from the air by the fitter media.
An Initial spark trap collects large partides before they reach
tfw prefilter. This trap further Isolates the fitters from sparks
in the case of a welding operation.
Upon leaving the trap, the air Is passed through pre-fitters.
These pre-fitters are desigr^ to catch the larger partides
leaving the trap. These reiatfvety Inej^nslve pre-filters pre­
vents the more eimensive main filter from becoming quickly
clogged. The pro-niters may be changed several times before
the main fitter needs to be changed.
ALL FACnrORY FURNISHED FILTERS HAVE A UU- CLASS
a RATING AND USING ANY FILTERS OTHER THAN THOSE
SUPPLIED FOR THIS UNIT IS NOT RECOMMENDED.
Use of any product other than that recommerKled by ttte
manufacturer wW void the warranty.
The main
avattaWe, depending upon the level of performance desired,
M of these ore high effidor>cy mutti-fkiw fitters which feature
extecKled surface area for long Bfe in high velod^ fUtratlon
systems. See the Replacement Parts 4 FWors section toward
the end of this maruiaJ for part numbers eiid fflter effiderKies.
Selection of the fitter best suited for,the Job should be rfls-
cussed with a dealer or a factory representattve. ’ ^
A differential pressure gage Is an Integral part of the. unft.
When the filters become dogged, the gage wBI Indicate an
Increase in differential pressure. At tttis point, the fitters
should be chor>ged. DoperKíingupontheappllcatkxi,th
0 pre-
fllter can be changed several times before the main fitter must
be changed. Changing the prefltters regularly can exterKl (he
usefiji life ot the fUiial mer up to 50%. Д .

UNPACKING
Carefully Irispoct the unit for corKested damage that may
have occurred during shipping and handling. If ary damage
Is fourxJ.Immedlatety contact me freight compary. Make sure
that there are no dents In the housing, as they ww prevent the
fitters from slldlr>g Into the units smoothly.
OPERATION
'• ■s'- ^ '
Your ACE Industrial Products machine Undesigned as a
source capftire device, l.o,. It Is Intended to eliminale smoke
atxl parficdate at their point of origia Keeping thU In mind,
the machine should be operated In the fotfawlng manner.
Re-read the soctkMi on Safety Wamirigs & Cautions before
proceeding any further,
>
1. Place the machine on a flat, level surface. Pick a location
that vrill allow unrestricted flow of the exhaust air to the
atmosphere.
2.
For
units with wheels or casters, lock the wheels or block
the wheels.
3. Place the collection nozzle as dose to the work as practi­
cal wfthout Interfering with the operator. Secure the nozzle
H necessary.
•
4. Using the OrVOff switch, turn the machine On. Should the
motor not start or should the machine make unusual
noises, immodlatety turn the macftine off ar>d seek tralr>od
malnterraf>ce personnel. Do not continue to use the de­
vice,
5. Upon completion of the spocfflc manufacturing or wefcflng
operatiott turn the machine off. Continuous running of the
machine will continue to remove particulales from the
general environmertt and wtn cause premature dogging of
the fitters.
6, When the‘fitter dogged* light or the differonllal pressure
gage (depertcling upon modeO bKflcate that the №er(s} are
dogged, turn the madtine off and remove the power cord
from Its power source. ■
See the section on IfistaHation and use the reverse proc­
ess to remove the dirty fitters. Re-Install new fitters and
reconriect thè machitw to tts power source.
GENERAL MAI^NANCE
ONLY QUAURED SERVICE TECHNICIANS SHOULD MAKE
REPAIRS TO THIS UNIT.
DO NOT REPLACE THESE MOTORS WITH MOTORS
OTHER THAN THOSE RECOMMENDED BY THE MANU­
FACTURER.
