Operation and Maintenance
1. Place the Porta-Vac on a sturdy work surface.
2. Attach the power cord to the receptacle on the
unit and plug the other end into a power outlet
following the safety guidelines in this manual.
3. The power switch (shown at right) is located
at the top corner of the fan door turns on the fan
motor and LED light. The DC cable must be
plugged in to use the LED light.
4. Clean and wipe the polycarbonate glass shield
with a soft cloth or paper towel. A non-
ammoniated cleaner (such as soap and water)
will remove greasy polishing compound dust.
5. The Porta-Vac has been fitted with a fine pleated
HEPA WASHABLE filter. Periodically check the
filter condition. If it becomes clogged with debris
you can remove it by opening the rear door of
the fan housing. You can either tap it on its side
in a trash can to gently remove large particles
and return it to its original position in the
chamber or, if it is heavily clogged, replace the
filter with a new one. Please make sure that the
filter is inserted all the way into the
compartment. Filters can be saved and sent to
a refiner to recover precious metals. The pleated
filter (Part No. 550-F) should be replaced every
4-6 months under normal use and more often
under heavy use. Contact your distributor or
Handler Manufacturing LLC to request a
550-F pleated filter.
6. To clean and remove the dust which
accumulates inside the Porta-Vac, lift the shield
as shown on the right. Remove the tray, and
place tray over the trash and empty contents.
7. With use, the shield of the unit may become
cloudy looking or scratched by debris. When
this occurs Contact your distributor or Handler
Manufacturing LLC to request a replacement of
shield P550-04P
8. The Porta-Vac has a Bussman GMC-1A fuse that powers the fan and the light. The fuse and a spare fuse
are stored in the AC power cord receptacle near the rear of the chamber.
To check or change the fuse, follow these directions:
Remove the power cord from the AC receptacle to
expose the fuse holder drawer. Use the blade of
a small screwdriver in the slot of the fuse holder
and gently pry outward. The active fuse is in the
back of the drawer and a spare fuse is in the front
compartment. If the glass case of the active fuse is
darkened, the fuse is blown. From the underside of
the drawer, push out the blown fuse using a small
screwdriver.
Do not use a higher ampere fuse.
