Wet-vac Setup

When using the CT-vac for damp or wet extraction, it is
important to configure the vacuum for wet collection. It is
also important to reconfigure the vacuum for dry extraction
afterward.
If the collection bag is not removed from the collection can-
ister, incoming moist air will cause the existing dust in the
collection bag to get wet and cake to the inside of the bag.
This will reduce the air flow through the bag and diminish
the suction of the vacuum. Likewise, if moist air reaches the
main filter, it will cause the filter to clog, and reduce suction.
When returning to dry collection, it is important to replace
the wet filter with the dry filter. The wet filter is not
designed to capture fine dusts, which would then pass
through the filter into the blower. It is also a good idea to
dry the interior of the vacuum and the collection hose so
that incoming dry dust does not adhere to the remaining
water inside the canister.
1. Remove the motor housing from the collection canister as
described on page 8.
2. Remove the dust collection bag. (Don't close the dust
gate unless you intend to dispose of the bag. However,
for a CT-Mini or CT-Midi, the dust flap can be closed and
reopened.)
3. Replace the dry filter with the wet filter as described in
the procedure to the left.
