Ensure that all T-fittings, hose cuffs, manifolds, supply
lines, and injectors are properly installed. Attach the ADS to
the DriForce. Plug in the DriForce and switch it on briefly,
checking all connections for air leakage. If needed, use a
hose clamp to seal off any air leakage where the vinyl prod-
ucts connect up to hose barbs, etc.
Drying Procedure
Phase 1: Air Extraction (Vacuum) Drying
Attach the ADS to the vacuum inlet of the DriForce
blower unit and switch unit on.
Use the air extraction (vacuum) mode to draw humid air
from structural cavities.
Operate Phase 1 until the humidity of the air being drawn
from the affected area is approximately the same as the
humidity in an unaffected area of the job. You can use a
hygrometer to compare RH readings between the outlet of
the DriForce and the surrounding area.
NOTE: Be sure to attach the vacuum hose to the DriForce
outlet and direct the exhaust air outside the structure. Do
not use the muffler-filter that is supplied with the DriForce in
the air extraction mode. This filter is not a HEPA-grade fil-
ter, and will not properly capture contaminants that may be
drawn into the DriForce. Use the muffler-filter only in the in-
jection (blower) mode, described below.
Phase 2: Air Injection (Blower) Drying
Attach the ADS from the vacuum to the pressure outlet
of the DriForce, install the muffler-filter on the air in-
take, and switch unit on.

Once the humidity inside the structural cavity equals the
humidity in the room, it is time to switch to the air injection
mode. Injecting room air into the structural cavities will help
continue the drying process. This is especially true if you
are dehumidifying the room air.
TIP: When drying inside walls, use an awl-punch or drill to
create a small vent holes placed just above the highest
moisture point on the wall. This will provide a vent and help
to speed up the drying process by allowing greater air flow
through the affected materials. A small hole can be easily
patched.
TIP: To maximize drying in walls that wainscoted, tile-cov-
ered, double-sheeted, or covered with vinyl wall paper or
impermeable paint, as well as lath and plaster walls, fire-
walls and insulated walls, place additional injectors per lin-
ear foot.
TIP: Accelerate drying with dehumidifiers. To increase
drying rates during Phase 2, use a dehumidifier to supply
dry air directly into the DriForce. Position the dry air outlet
of a dehumidifier near the DriForce air inlet, or duct the de-
humidifier outlet toward the DriForce inlet. Desiccant de-
humidifiers are especially useful for this purpose, as
the extremely dry air they produce can accelerate the dry-
ing of dense materials and assemblies.
NOTICE: Do NOT tape or seal the dehumidifier ducting to
the DriForce inlet, as this could unbalance the airflow
through the dehumidifier and possibly damage the dehu-
midifier.
Odor and Mold Control
If you suspect that mold and mildew may be growing inside
cavities, follow the appropriate industry
mold remediation procedures and
safety standards.
MAINTENANCE
WARNING: Always unplug
unit prior to servicing or
cleaning.
As needed
Check both the inlet and outlet of the
DriForce unit for obstructions or debris
after each use.
Inspect the muffler-filter, and clean as
needed by vacuuming or washing.
Check manifolds, tubing, injectors and
other ADS components, and replace if
needed.
Clean the exterior of the DriForce and
ADS components with a vinyl cleaner
and protectant.
