INTRODUCTION
MAJOR COMPONENTS
Cabinet
The cabinet is fabricated out of satin coat mild steel and is
painted via powder coating. The Enviroflexname etc. are
all silk screened over the powder coated paint.
Filter Maintenance
The ESE202A Portable Smoke Extractor unit uses
disposable cartridge type filters. The operating life
expectancy of the filters depends on the type of smoke being
removed, the severity of the smoke and the duty cycle. It is
extremely difficult to pinpoint how many pounds of
consumable wire or electrode that can be deposited before
the filters plug up. This is extremely difficult to estimate as
there are too many variables.
Your suction will start to deteriorate when either or both of
the filters start to load up with particulate. Once the suction
is inadequate you have to analyze whether the prefilter or the
HEPA filter is plugged. First pull out the prefilter and start
up the machine with only the HEPA filter in it. If the suction
climbs dramatically then the prefilter (EF 100) is plugged
and needs replacing. If pulling out the prefilter makes no
difference in the suction then it is time to replace the HEPA
filter (EF 200). Normally you replace 3 or 4 prefilters for
every HEPA filter.
To replace or clean filters:
(1) Turn off the Smoke Extractor and pull out the
electrical plug from the wall receptacle.
(2) Unfasten the (2) latches located at the front of the
machine. Remove the spark trap.
(3) Pull out both cartridge filters and inspect the small
primary filter (EF100) which can be blown out
using a low pressure air nozzle. You take the
prefilter and turn it upside down and blow it from
the outside only. You utilize the gasket on the front
of the filter to eliminate blowing the contaminant all
over the shop. The larger HEPA filter (EF200) is
not a filter which can be cleaned, so when this filter
is loaded up it must be thrown away. Do not
attempt to blow out this filter as the paper will
likely rip. Normally you will replace the EF200
HEPA filter for every 3 or 4 prefilters that are
replaced. This is only an approximate estimate.
(4) Place the new cartridge filters back into the cabinet
making sure the outer gasket of the large filter
comes in contact with the cabinet rim.
(5) Before placing the spark trap on the unit you should
shake the spark trap to remove any heavy
particulate that has been caught inside behind the
impinger plate.
(6) Reinstall the spark trap in the cover and place the
spark trap over the front of the cabinet making sure
that the cover is seated correctly on all edges of the
cabinet. Tighten the (2) latch catches.
(7) Plug the machine back into the wall receptacle and
turn the unit on. You are now ready to use the
Smoke Extractor again.
Charcoal Filters
If you have purchased the (2) optional charcoal filters it is a
very easy installation. To install them you have to remove
the spark trap then remove the EF100 and EF200 filters.
Install the 2 charcoal modules by butting them up against the
motor hole plates at back of the filter plate. Please note it is
vital that the flat portion of the charcoal cassette is facing the
filters. Otherwise the air does not get a chance to expand
before entering the motor and would only utilize a small
porting of the charcoal the size of the motor inlet hole. Re-
install the EF100 and the EF200 filter. Install the filter plate
and the spark trap.
The charcoal will have to be replaced when odors can be
detected coming out of the louvers on the 2 sides of the unit.
Electrical Service
The (2) electric motors are equipped with replaceable
brushes. Once they become worn the motor will
automatically stop, thus eliminating any potential damage to
the commutator. To replace the brushes be sure that the
power has been turned off and the power cord has been
removed from the wall outlet. Unscrew the four screws
located at the rear of the cabinet to allow access to the
motors. Remove the protective fan cap by lifting the metal
clips which are located on the sides of the cap. Remove the
hold down screw which secures the brush in place and pull
off the bayonet connector from the brush. Remove the old
brush from the motor and install the new brush by reversing
the above procedure. Replace the cap and screw the motor
housing plate back onto the back of the cabinet. The
ESE202A unit is now ready to operate.
