AutoClean Setup

The CT-AC series of vacuums have the optional AutoClean
function. When enabled, the AutoClean function sends a
pulse of air backward through the main filter to dislodge
caked dust from the filter, as described on
The purpose of the AutoClean function is to circumvent the
frequent clogging of a normal filter bag when ultra-fine
dusts are collected. Therefore, the AutoClean function is
intended for use without a filter bag installed in the vacuum.
(Even though a bag could be installed, it would diminish
the effect of AutoClean.) To aid in emptying the collection
canister, a dust liner is recommended.
For AutoClean mode, it is recommended to use the CT
AC High-Performance filter (496 172). This filter is rated
for 1-micron filtration, instead of the 0.3-micron filtration
of a HEPA filter, and is designed for the AutoClean back-
flow pulses. A HEPA filter should be used only when the
AutoClean function is disabled.

Non-AutoClean Mode

The CT-AC vacuum may be used as a typical shop and
household vacuum by disabling the AutoClean feature and
installing a normal filter bag. To disable the automatic clean-
ing cycle, turn the frequency dial to the "0" (Off) position.

Manual AutoClean Mode

A manual cleaning cycle may be initiated by turning the
main power switch to either of the two "AC" (AutoClean)
positions momentarily. The vacuum will produce several
AutoClean pulses in succession. A manual AutoClean cycle
should be performed periodically to perform a deeper clean-
ing that the automatic AutoClean timing. It should also be
performed prior to emptying the collection canister.
Ideally, the vacuum inlet or hose inlet should be blocked
before the cleaning cycle to provide the deepest cleaning.
The optional VS-CT-AC blast gate allows you to block the
inlet without having to disconnect the hose or the tool.

1. Block the inlet to the vacuum or the end of the hose.
2. Momentarily rotate the power switch to either of the two
"AC" positions. The switch may be released to either the
"Man" or "Auto" positions, or it may be turned to the off
position.
3. After the vacuum has stopped pulsing, unblock the inlet.

Automatic AutoClean Mode

In automatic AutoClean mode, the vacuum will initiate
AutoClean cycles without interrupting the operation of the
vacuum, with only a brief reduction in suction at the hose.
The frequency of the AutoClean pulses is controlled by turn-
ing the frequency dial. Turning the dial clockwise increases
the frequency of the pulses, and turning the dial counter-
clockwise decreases the frequency. Turning the dial all the
way counterclockwise will disable the automatic AutoClean
system.

Using Dust Liners

Dust liners are not bags, but are open-faced to line the bot-
tom of the collection canister to make emptying the canister
easier. The liners have two vents on the side. These are not
for normal airflow, but instead, are to equalize the air that
would otherwise be trapped under the liner, and allow the
liner to lay flat in the bottom of the canister.
Changing the dust liner is similar to changing a collection
bag. Refer to "Changing Collection
additional details.
1. Place the liner in the bottom of the collection canister and
secure the flange to the vacuum inlet in the same man-
ner as a collection bag.
2. Wrap the edges of the liner around the lip of the collec-
tion canister, so that when the motor housing is replaced,
it holds the liner in place.
Make sure the 3 electrical contacts near the vacuum

inlet are not covered by the plastic liner. The center
electrical contact is the grounded connection for the
anti-static hose.
Make sure the two vent panels are inside the canister. If
►
the vent panels are not inside the canister, the dust liner
will balloon up when the vacuum is turned on.
3. When emptying the full liner, use the attached tie wrap to
seal the top of the liner.
