Troubleshooting
No Power
(Vacuum pump does not
run)
Power switch located on right of control
panel may be off. Switch to “ON” position
(display will light up).
The sample is too large. Remove one or
more filler plates.
Power cord loose or
damaged.
Check to ensure wall outlet is working.
Plug in a different appliance to verify.
Power cord attached securely?
Check fuse on front panel. (pg. 43)
No Vacuum
(pump runs but lid does not
stay closed)
Check black seal gasket in the lid. It
should be seated evenly in the groove
and there should not be any cuts, gaps or
debris.
Vacuum ports are
blocked or clogged.
The sample bag is blocking the two
vacuum ports in the rear of the chamber.
Your bag may need to be repositioned.
Cut or disconnected
hose.
Hose accidentally cut or disconnected
during recent servicing or oil change.
Contact InstroTek.
Damaged or broken
seal wire.
Call for replacement seal bar or wire and
tape.
Check fuse on front panel. (pg. 43)
Inadequate Seal
(seal appears too light,
spotty, or inconsistent from
end to end)
Wrinkles in the bag or
debris in the sealing
area.
If the sealing surface in the bag is smooth,
clean and free of debris. If the sample is
too big for the bag, you may not be able
to lay the open end of the bag evenly
across the seal bar.
Make sure tape over the seal wire is
smooth and wrinkle free.
Center the bag evenly over the seal bar.
Make sure the bag width is not larger than
the seal bar width.
Punctures on the
sample edges
Make sure the sliding plate is used with the
smooth side down. Make sure the top of
the sample is not hitting the chamber
door. Remove one or more of the filler
plates. Make sure the bags are not
damaged by inspecting prior to use
Damaged or worn
silicone seal pad in lid
(above seal bar).
The silicone pad is not firmly seated in its
holder or it is cut, damaged or not smooth.
Replace if necessary.
Tape on seal bar is not
even or smooth.
Worn or frayed. Replace if necessary.
