control at the location shown in FIGURE 14 . Route
the connector wire through the channels in the
control and reattach the control to the mounting
plate . Restore power to the HVAC system and plug
in the ventilator when complete .
If the 8142 ventilator is ducted to the return

damper is installed (see FIGURE 6 on page 4),
an additional transformer (Aprilaire part number

transformer does not have enough capacity to
power a damper (10 VA required) .
1. Cut the plug off of the end of the control
connector (see FIGURE 11) and strip
approximately 1/4" of insulation off the end of
each of the orange wires .
2. Insert one of the orange wires into one of
the "VENT" terminals and use a wire nut to
connect the other wire to one side of the
added transformer (see FIGURE 15) .
3. Wire the damper motor and transformer as
shown in FIGURE 15 .
4. Restore power to the HVAC system and plug in
the ventilator when complete .
