Making air access holes
Punch holes with a carpet awl or use a drill with a
3⁄16 in. bit. Create at least one hole between each set
of studs and about 2 in. above the floor. An electronic
stud finder can be used to locate studs and find the
center of the cavity.
Larger holes are more time-consuming to patch, and
may decrease efficiency by leaking air. Try to reduce
the need for later repairs by placing the holes behind
the rubber wainscoting or cove base, or behind trim
that is easily reinstalled over the holes.
Steel Studs
Steel studs are common in commercial building s.
They are set in a channel that can hold large volumes
of water. To access these areas, drill holes approximately ½ inch from the floor at a downward angle. Take
care, however, not to immerse the ends of the tubes in any
standing water that may be present.
Ceilings and Cabinets
The larger lumber sizes and structural cavitie s in ceilings
will require more air airflow to dry properly.
Moisture under and behind cabinets may be difficult to detect, but it is safest to assume that moisture is present if
water has flowed through these assemblies. Make sure to
provide as much airflow as possible. If you cannot properly
OPERATING INSTRUCTIONS
IMPORTANT: Extract standing water before attempting
to dry. Do NOT use the DriForce to extract standing
water of any kind.
Tools
Pencil, tape measure, razor knife, drywall taping knife,
small pry bar, nail puller, screw driver, a carpet awl, a drill
with a 3⁄16 in. bit. An electronic stud finder is also useful.
Preparing Walls, Cabinets and other Assemblies for Drying
Walls
Wall drying using an inter-air drying system can be accomplished with or without baseboards pres ent. A fter inspecting walls, insulation, and baseboards, and after evaluating
paint finish considerations, proceed in the manner that delivers the most value to the customer.
Remove baseboard or cove base. First, use a razor knife to
score along the top of the base where it meets the wall, to
reduce damage to the painted surfaces and make a professional re-installation easier. When prying base away
from the wall, protect the wall surface by inserting a drywall
knife between the pry bar and the wall. Pull remaining nails
out of the wall, or through the back of the baseboard. Write
a number on the wall and the corresponding base so you
will know where to reinstall it. However, drying success can
also be achieved by making the wall penetrations immediately above the top of baseboard and proceeding to dry
with the baseboards in place. This a necessary procedure
where there is a desire to save a wall with a tiled wall base,

The DriForce and the Air Drying System can deliver air to structural cavities in walls, ceilings, under and above cabinets, and
many other areas.
The ADS co nnects to the DriForce blower outlet and attaches
to a manifold with a standard hose cuff. Supply tubes run
from the manifold to injectors that are inserted into a wall o r
other structural cavity.

NOTICE: Do not use the DriForce to extract liquid water or

After determining the number and length of hose assemblies and manifolds, set up the ADS system. Preassembling the manifolds, tubing and injectors will save
considerable time.
Supply tube configuration
Two 200 ft. (60 m) lengths of of ⅜ in. (0.375 mm) ID ai r supply
are provided. This tubing can be cut to length with a
tubing

cutting following tubing lengths to create a setup suitable
for most standard wall-drying jobs:

lines running from a T-fitting. It also shows tubing layouts for
one or two injectors into each wall cavity.
DriForce Blower Setup
The DriForce Blower is equipped with a blower outlet, a
vacuum inlet, a power switch and a power cord. Plug in unit
to an appropriate grounded 115V outlet rated for 15 amps.
Attach vacuum hoses to the vacuum inlet and/or blower
outlet.
Set the DriForce blower out of high traffic areas to minimize
a trip-and-fall hazard from the blower and the ADS.
NOTE: The muffler/filter supplied with the DriForce should
only be installed when using the DriForce in the Air Injection (Blower) mode, described under Phase 2 below. Do
not use the muffler-filter w hen usin g with the DriForce in
the air extraction mode (Phase 1). The filter is not intended
to be used on the inlet (vacuum) side of the DriForce.
Switch power on and off with the toggle switch, found in the
base of the unit.
Air Drying System (ADS) Setup
Manifold configuration
Next, determine the number of manifolds needed for the
job. The following setup will deliver 25 to 30 air exchanges
per hour in each cavity, which is effective for most situations. Use a formula of one manifold (each manifo ld has 12
injectors) for each 14 feet of interior 2 × 4 framed wall. For
2 × 6 exterior framed walls, common walls in apartments
and condos, double-sheeted fire walls, and dense or waterresistant covered walls, use a formula of one manifold (12
injectors) for each 7 feet of wall.

To install the tubing, slide the one end of the tubing over
the manifold outlet nipple and insert an injector in the other
end.
Tightly seal off the last manifold on each run of ADS with
an end-cap plug. Now place the injectors into the holes you
have drilled or punched in the wall, cabinet or other assembly.
Ensure that all T-fittin gs, hos e cuff s, mani fold s, sup ply
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
products 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
filter, and will not properly capture contaminants that may
be drawn into the DriForce. Use the muffler-filter only in the
injection (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 intake, 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, tilecovered, double-sheeted, or covered with vinyl wall paper
or impermeable paint, as well as lath and plaster walls,
firewalls and insulated walls, place additional injectors per
linear 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
dehumidifier outlet toward the DriForce inlet. Desiccant
dehumidifiers are especially useful for this purpose, as
the extremely dry air they produce can accelerate the drying 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 dehumidifier.
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.
