BEFORE YOU BEGIN

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,
when value is added by avoiding the detachment of
wall baseboards.

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 buildings. They are
set in a channel that can hold large volumes of water. To
access these areas, drill holes approximately ½ inch from

Preparing Walls, Cabinets and other As­semblies for Drying

Walls

Wall drying using an inter-air drying system can be accom­plished with or without baseboards present. After 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 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 cavities 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
access all interior spaces, the cabinets may need to be re­moved.

NOTICE: Do not use the DriForce to extract liquid water or
debris of any kind. This may damage the unit and void the
warranty.

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 manifold 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.

After determining the number and length of hose assem­blies and manifolds, set up the ADS system. Pre-assem­bling the manifolds, tubing and injectors will save consider­able time.

Supply tube configuration

Two 200 ft. (60 m) lengths of ⅜ in. (0.375 mm) ID air supply
tubing are provided. This tubing can be cut to length with a
pair of sturdy scissors or a utility knife. We recommend the
cutting following tubing lengths to create a setup suitable
for most standard wall-drying jobs:

1. Set up THREE manifolds with the following lengths
of tubing:

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 when using 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.

07-00274K F211, F211-AK, F211-BU 3 Dri-Eaz Products, Inc.

2. Set up the remaining FIVE manifolds with the follow­ing lengths of tubing:

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-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 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, tile-cov­ered, 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 de-
humidifiers 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.

warranty information are available from
