3-05 2 of 16 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. Cut a 2-1/2" diameter hole in the sole plate, header, or stud directly in line with the opening of the inlet fitting (Figure 5). 2-1/4" Figure 5 Figure 6 2.Measure the length of tubing needed to connect into the main trunk line, adding approximately 3/4" of tubing for insertion into fittings. 3.Cut the tubing, taking care to keep the straight square edge. The use of a miter box is recommended (Figure 6). 4.Remove rough edges with a utility knife or coarse sand paper (Figure 7). Tape Low VoltageWire Extra wire for inlet connection Figure 7 Figure 8 5. Dry fit all pieces and ensure proper fit and alignment before cementing. 6. When dry fitting tubing, run low voltage wire (minimum, solid 18 gauge, two conductor) by 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. 7. 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). Cement 1" Cement Applicator Figure 9 Figure 10 8. 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 Wall Inlet Models CVIV60A or CVIV60W CAUTION: INSTALLATION WORK AND ELECTRICAL WIRING MUST BE DONE BY QUALIFIED PERSON(S) IN ACCORDANCE WITH ALL APPLICABLE CODES AND STANDARDS, INCLUDING FIRE-RELATED CONSTRUCTION. CAUTION:MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE STARTING INSTALLATION. 1. Once the drywall has been completed, the wall inlets can be installed. Start by checking the mounting plate for any debris that might have been left from the drywall process and clean if necessary. 2. Connect the low voltage wire to the terminal screws on the rear of the wall inlet (Figure 11). Figure 11 Figure 12 3. Align the inlet screw holes with the mounting plate holes and 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 (Figure 12). Installing Electric Wall Inlet Models CVIV65A or CVIV65W CAUTION: INSTALLATION WORK AND ELECTRICAL WIRING MUST BE DONE BY QUALIFIED PERSON(S) IN ACCORDANCE WITH ALL APPLICABLE CODES AND STANDARDS, INCLUDING FIRE-RELATED CONSTRUCTION. CAUTION:MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE STARTING INSTALLATION. 1. Before the drywall is installed, run wire from a nearby electrical outlet box or junction box through the supplied strain relief and into the hole in the mounting plate, leaving about 10" of excess to make the connections to the inlet. Secure the wire in place by tightening the strain relief (Figure 13). Strain Relief SupplyWires from Electrical Box Wire Nut Low VoltageWire Figure 13 Figure 14 2. Cap the loose wires and tuck back inside of mounting plate. Once the drywall has been completed the wall inlets can be installed. Start by checking the mounting plate for any debris that might have been left from the drywall process and clean if necessary. 3. Connect the low voltage wire to the terminal screws on the rear of the wall inlet. Second connect the black wire from the supply to the black wire of the inlet, then connect the white wire from the supply to the white wire of the inlet. Use approved electrical wire nuts for all connections (Figure 14). 4. Align the inlet screw holes with the mounting plate holes and 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 (Figure 12). NOTE: The electrified wall inlet should be listed on the inspection report for building inspection purposes. 000000 Rev A. 3-05 3 of 16 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). Pilot Hole Sole Plate Drywall Baseboard 2-1/4" + Pilot Hole 2-1/2" Hole Figure 15 Figure 16 2. From below, locate the pilot hole and measure over approximately 2-1/4" (1/2" for the drywall + 1-3/4" to the ...
