WARNING
Warning: Do not allow the yellow lead from the Ultra-Aire
to contact the red lead or orange lead from the Ultra-Aire or
damage to the transformer will result.
The installer must supply the wiring between the Ultra-Aire and
the control panel. Be sure to safely route the control wires to
prevent damage during installation. Be careful not to cross wires
when connecting the Ultra-Aire and the remote control panel or
damage to the transformer may result.
IMPORTANT
The remote controls of the
Ultra-Aire are powered by a
low voltage circuit (24 VAC)
and must NEVER contact or be
connected to a high voltage
circuit.
Some of the control wires may
not be used with certain control
panels and should be left safely
disconnected with wire nuts
taped onto the stripped ends. Be
sure to consult the electrical
schematic in this manual
before making the control
connections.
