PRE-OPERATING INSTRUCTIONS
NOTE: The SC150 is shipped in two cartons. Carton 1 contains the
main unit w/ instructions. Carton 2 contains the arm (or arms)
assembly.
1. Upon receipt, remove the units from cartons. Inspect for any
freight damage that may have occured during shipping.
Report any damage to the freight company.
2. Remove filter access door by removing the two phillips head
screws as shown. Grasp the underside of the door offset
and lift slightly to remove. (FIG. 1)
FIG. 1
3. Looking inside the unit, remove the two (2) filter spring
retainers and pull out the foam prefilter, HEPA filter and
charcoal/ purasorb filter. REMOVE THE PLASTIC WRAP
THAT PROTECTS THE CHARCOAL/ PURASORB FILTER
DURING STORAGE.
4. Remove the arm assembly from the second carton consisting
of one or two flexible hoses and a black formed plastic
manifold. Taped to the underside of the manifold is a clear
bag containing four (4) black screws. Remove screws and
disgard bag.
5. Place the plastic manifold upon the large oval hole on the
SC150 cabinet, align the four pre-drilled holes on the
manifold to those on the cabinet.
6. Using a slot head screw driver, secure the plastic manifold
and hose assembly to the cabinet with the four (4) self
tapping black screws obtained from step 4. (FIG. 2)
FIG. 2
7. Re-install filters removed in step 2 and secure with filter
spring retainer. NOTE: Filters should be pressed firmly into
unit for positive seal resulting in no filter bypass. Replace
the filter access door.
NOTE: INSTALL CHARCOAL FILTER BEFORE HEPA
FILTER.
OPERATION
1. Before operating, simply plug the SC150 power cord into
any grounded electrical outlet rated at nameplate voltage.
2. Once the SC150 has been plugged in, turn the unit on.
Position inlet nozzle(s) approximately 6” from point of
containment to be captured.
IMPORTANT: TAKE CARE TO SEE THAT THE INLET
NOZZLE(S) DO NOT TOUCH HOT SURFACES SUCH
AS SOLDERING IRONS, WHICH WOULD BE RESULT
IN THE DEFORMATION OF THE PLASTIC NOZZLE.
3. The SC150 has a fan-cooled, thermally protected motor,
and is designed to operate for continuous duty if required.

NOTE: After some time,the flexible hose may not hold in a horizontal
position. This can be fixed by simply twisting the hose
counterclockwise thereby slightly reducing the hose diameter and
tightening the segmented joints.
OPTIONAL INSTALLATION APPLICATIONS
This section displays options available to the SC150 for specific
applications:
A. Table Bracket Mounting (See FIG. 3.)
1. This option is designed when the customer wishes to place
the unit on the floor and clamp the hose to a bracket on the
table. This clears space for the worker.
FIG. 3
B. Optional Wall Mount Assembly for Vertical
Installation. (See Fig. 4)
1. This installation allows the SC150 to be mounted on a
wall in a vertical position. The exhaust is then pointed
upward, and the arm (or arms) is at the bottom end,
close to the work area.

TO THE WALLBOARD, BE CERTAIN THAT SCREWS
ARE SECURED TO WALL BOARD VIA WALL JOISTS,
OR BY MEANS OF A THREADED INSERT. WALL
BOARD MATERIAL IS NOT INTENDED TO SOLELY
HOLD WEIGHT OF THE AIR CLEANER.
NOTE: Cord is 8 feet long; unit must be installed within
reach of an electrical outlet.
4.Once the wall bracket and unit bracket are in place, lift the
SC150 and mount to the wall bracket. (FIG. 4.)
C. Optional Wall Mount Assembly for Horizontal Installation.
(FIG. 6)
This installation provides wall brackets that allow the SC150 to be
mounted in a horizontal position.

CAUTION: WHEN MOUNTING WALL BRACKETS TO
WALLBOARD, BE CERTAIN THAT SCREWS ARE
SECURED TO WALL BOARD VIA WALL JOISTS, OR BY
MEANS OF A THREADED INSERT. WALLBOARD
MATERIAL IS NOT INTENDED TO SOLELY HOLD THE
WEIGHT OF THE AIR CLEANER.
NOTE: Cord is 8 feet long. Unit must be
installed within reach of an electrical outlet.
2. Set the SC150 upon wall brackets as shown, making sure
that brackets are located between plastic feet.
3. Once the SC150 is in position as shown, secure the unit to
the wall brackets using the No. 8 x 1/2” sheet metal screw
supplied with this unit.
IMPORTANT: INSTALL SCREW TO EXHAUST END SIDE
AS SHOWN.
MAINTENANCE
1. Normally the HEPA and Charcoal/purasorb filter will be
maintenance free with an average life of about 6 months.
A good indicator for HEPA filter replacement is when air flow is
noticably less than normal and unit has difficulty in capturing
contaminant.
FILTER REPLACEMENT
CAUTION: BE SURE UNIT IS OFF OR UNPLUGGED BEFORE
SERVICING.
1. Remove filter access door. (Refer to step 2, Pre-Operating
Instructions.)
2. Remove filter spring retainers and pull out foam mesh prefilter.
Wash prefilter in a mild detergent. Rinse thoroughly and press
excess water from filter using a towel or cloth.
3. When cleaning the prefilter, inspect the HEPA filter. If
necessary, replace with a new filter. (See parts list for filter part
number.)
4. After approximately 6 months of use, the charcoal purasorb
filter will need to be replaced. Remove the filter by grasping
the tabs attached to each side of the filter and pull out from
unit.
5. Whenever servicing filters, remember to press filter spring
retainers back into prefilter so that gasket of charcoal
purasorb filter is sealed against the cabinet flange. This will
insure total seal against filter to eliminate contaminated air
bypass.
