The Model 8144NC Fresh Air Ventilator must be hard wired. An electrical disconnect switch can be installed as needed to comply with appropriate
codes or ordinances. The ON/OFF switch on the ventilator interrupts the 115VAC service to the blower of the ventilator, but does not disconnect the
power supply input to the unit.
1. Disconnect electrical service at the fuse or circuit breaker that will be
serving the ventilator.
2. Run electrical service to the ventilator. Install an electrical disconnect
switch located as required by national and local code and label it as
a "MECHANICAL VENTILATION" switch to differentiate it from other
switches. A label is provided inside the ventilator carton. See FIGURE 3.
3. Remove the motor speed adjustment knob and take off the cover by
removing the two retaining screws. Remove the cover insulation to
