5.2B Wiring
WARNING:
DO NOT ALLOW THE YELLOW LEAD
FROM THE ULTRA-AIRE TO CONTACT THE RED OR WHITE LEADS
FROM THE ULTRA-AIRE OR DAMAGE TO THE TRANSFORMER
WILL RESULT
WARNING:
UNPLUG ULTRA-AIRE BASE UNIT
BEFORE WIRING CONTROL.
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
the wires when connecting the Ultra-Aire and the remote
control panel or damage to the transformer may result.
The remote control of the Ultra-Aire is 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
leaving the Ultra-Aire 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 or on the front panel of the Ultra-
Aire before making the control connections.
