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.
