Wall Drying
Step #1 – Access Wall Cavity
1. Remove the base board from the wall. Remove the base board carefully, including cutting any caulk bead
at the top to prevent damage to the drywall. If not damaged, the base board can be re-installed after the
drying process is completed.
2. Locate the wall studs in the area to be dried.
3. Drill 1" diameter access holes through the wall. Locate the holes between the studs, just above the wall
base plate. Whenever possible place holes where they will be covered by the base board after drying is
completed.
4. Insert one Flexi Dry outlet barb or hose into each hole. Turn tube to point air flow in the desired
direction. Multiple Flexi Fry units can be connected together for larger areas.
Step #2 - Energy applied directly to the water (Temperature)
1. Insert the snout of the E-TES SD unit into the large opening of the Flexi Dry. Secure the Flexi Dry to the
E-TES SD snout with the Velcro strap and the carpet clamp. Seal the ends of the Flexi Dry to prevent air
leaking. When using multiple Flexi Dry units connected together, seal the Velcro strips on the other large
openings to prevent air from leaking out.
2. Insert a centrifugal air mover into the E-TES
SD box. Plug the air mover cord into a wall
outlet. Connect the two GFCI power cords to
the E-TES SD 120volt unit and plug the cords
into two different 120v circuit outlets.
3. Place remote sensors for air temperature,
surface temperature and moisture level as needed in desired locations. Connect the sensors to the E-TES
SD.
4. Turn on the E-TES SD unit and adjust the set points for each
of the remote sensors as required for your application.
5. Turn on the air mover.
6. In some cases the Flexi Dry may restrict the E-TES SD outlet
air flow enough to overheat and engage the E-TES snout
temperature sensor or the Safety Overtemp switches.
When using the FlexiDry, the Overtemp Light will often turn
ON & OFF as the snout overheats and cools off. The E-TES
SD will continue to operate and no adjustments are needed.
However if the air flow is restricted too much, the Heater
Safety Overtemp switches will engage, the unit will cycle ON & OFF a few times before it locks in the
OFF position and will not turn back ON until the E-TES power is turned OFF and back ON.
To prevent this, open one end of the Flexi Dry to increase the total airflow. Opening the end just a small
amount should increase the air flow enough to keep the E-TES SD operating. Opening the end too much
may reduce the flow through the outlet tubes and increase the drying time.
Step #3 - Airflow applied directly to the water (Evaporation)
1. We are getting air movement into the wall with the air mover / E-TES SD box and the Flexi Dry system.
We are heating the water to cause the evaporation, but the water vapor still needs to be removed from the
wall.
If the wall is wet top to bottom, air outlet holes may need to be drilled at the top of the wall between the
2.
studs to allow the water vapor to be removed from the wall cavity. If the wall is only wet at the bottom,
drill an outlet hole below the baseboard level to allow moist air to escape
