UNDERSIDE COVER

Choose a suitable location to mount the OAS. The OAS can be configured to mount on an outside

air duct or an outside wall. If mounting on a wall, simply fasten the box to the outside wall

using the two 1/4” hex head self-tapping screws and wall anchors provided. The box should cover

the hole penetration made in the wall. Now route 2x18AWG field wire through the center hole and

into the box. Press the sensor into the brackets on the underside of the front cover. Use the

provided wire nuts to connect to the SAS sensor wires. Place the cover back on and secure it.

Connect the #18AWG field wires to the correct terminals on your Ultra-Zone control panel. The 1/4”

bracketed tube and rubber end cap are not used in this configuration. See Page 3 for duct

mounting configuration.
