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 07-00274L F211, F211-AK, F211-BU 2 Legend Brands, Inc.

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 is 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 12 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 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.

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.

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 water-resistant 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 38 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:

Manifold no.	Tubing quantity	Tubing length	Tubing locations on manifold outlets
1	4	4 ft. 1.2 m	Outlets 1, 2, 11 and 12
2	4	3 12 ft. 1 m	Outlets 3, 4, 9 and 10
3	4	1 ft. 30 cm	Outlets 5, 6, 7 and 8

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

Manifold no.	Tubing quantity	Tubing Length	Tubing locations on manifold outlets
4	2	712 ft. 2.3 m	Outlets 1 and 12
5	2	612 ft. 2.0 m	Outlets 2 and 11
6	2	512 ft. 1.7 m	Outlets 3 and 10
7	2	412 ft. 1.4 m	Outlets 4 and 9
8	2	212 ft. 0.8 m	Outlets 5 and 8
9	2	1 ft. 30 cm	Outlets 6 and 7

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 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.
