Installation into Existing Construction

Installing the Inlet Valves

1.Once the desired location of the inlet has been determined, drill a small pilot hole through the subfloor directly below the center of the inlet and as close to the wall as possible (Figure 15).

8.Align the inlet screw holes with the mounting plate holes and lightly press the inlet into place, guiding any extra wire back through the mounting plate as you go. Attach wall inlet to mounting plate with provided screws making sure mounting plate is properly seated in hole (Figure 12).

NOTE: Do not cement wall inlet to mounting plate, the built in mounting plate gasket will provide a positive seal.

Installing the Tubing

NOTE: When installing the tubing, start at the farthest inlet and work towards the power unit. Keep the tubing as straight as possible with the least amount of elbows and tees as possible to ensure maximum performance of your system. When installing tees or elbows, make sure the curve in the fitting is aligned so that the air flow is towards the power unit.

1.	Measure the length of tubing needed to connect into the main trunk line,
	adding approximately 3/4" of tubing for insertion into fittings.
2.	Cut the tubing, taking care to keep the straight square edge. The use of a
	miter box is recommended (Figure 6).
3.	Remove rough edges with a utility knife or coarse sand paper (Figure 7).
4.	Dry fit all pieces and ensure proper fit and alignment before cementing.
5.	When dry fitting tubing, run low voltage wire (18 gauge, two conductor) by

2.From below, locate the pilot hole and measure over approximately 2-1/4" (1/2" for the drywall + 1-3/4" to the center of a standard 2" x 4" sole plate). Add extra for any additional material such as baseboards, thicker drywall, etc. Using a 2-1/2" hole cutter, drill through flooring and sole plate. Using a flashlight, inspect the interior of the wall to confirm that there are no obstructions (Figure 16).

NOTE: Installation height will depend on personal preference, but generally the inlet is installed 18" above the finished floor.

3.After confirming that there are no obstructions within the wall, cut a 2-1/2" x 4-3/8" hole in the wall at the desired wall inlet location (Figure 17).

securing to tubing with tape. Allow approximately 6" of excess wire for

connection to each inlet (Figure 8).

NOTE: PVC solvent cement “welds” the fitting to the tubing through a chemical reaction to produce an air tight seal. It is important to make sure all surfaces are clean and free of burrs to ensure a proper seal.

6.Once all tubing has been cut, cleaned, and checked for fit, apply model CVFA35 PVC cement (not included) or equivalent cement to the outside of the tubing covering about 1". DO NOT allow any of the cement to enter the inside of the tubing (Figure 9).

7.Insert tubing with cement into fitting with a twisting motion to ensure the cement has been evenly spread. Check that the tubing is evenly seated in the fitting and is aligned properly with the rest of the line (Figure 10).

Installing the Power Unit

1.Determine a mounting location within 5 feet of a grounded electrical outlet and install the included mounting bracket (located inside of collection canister during shipping) using at least two appropriate screws (not included) for the wall material (Figure 21). The bracket must be level and mounted high enough to allow a minimum of 18" from the floor to the bottom of the collection canister.

Figure 17 Figure 18

4.Remove the perforated section of the mounting plate (Figure 18) and cement a model CVFE90S short 90° elbow to the mounting plate, facing the correct direction to make the connection to the tubing (Figure 19) (see step 7 in Installing the Tubing section for cementing instructions).

5.Tape the low voltage wire (minimum, solid 18 gauge, two conductor) to the end of a sufficiently long enough piece of tubing and pass it up through the previously drilled hole (Figure 8).

6.Remove the wire and pass it through the upper hole of the mounting plate and connect to the terminal screws on the rear of the wall inlet (Figure 11).

7.Angle the mounting plate and elbow into the previously cut hole in the wall and make the connection with the tubing (Figure 20).

2.Hang power unit on bracket so that it is properly seated between the two brackets of the power unit and tighten cross bolt (Figure 21).

3.Make tubing connections by cementing intake tubing (from the inlets) to the intake valve and connecting exhaust tubing to the exhaust valve. An optional model AKCVM1 sound muffler (not included) can be installed to the exhaust tubing to reduce the sound of the exhaust air (Figure 22).

NOTE: Exhaust should not be vented into a wall, ceiling, or concealed space within the home. It is best to exhaust to the outdoors.
