C7232A,B SENSOR AND CONTROLLER
Location and Mounting
C7232 Sensors mount directly on the wall, sheet metal duct,
or a panel. When planning the installation, allow enough
clearance for maintenance and service. Mount the sensor in a
well-ventilated area.
NOTES: Do not install the sensor where it can be affected by:
— drafts or dead spots behind doors and in corners.
— air from ducts.
Wall Mounting
The C7232 Wall Mount models can be mounted using two or
four screws:
1. Remove C7232 cover.
2. Mount the subbase to the wall using washers and two or
four screws (not supplied) appropriate for the wall
material.
NOTE: When mounting on a junction box, see Fig. 4.
3. Replace the cover.
Duct Mounting (see Fig. 5)
1. Place gasket on aspiration tube.
IMPORTANT
Ensure largest tab at tube control end is at the top.
2. Insert tube into duct; attach using screws and washers.
IMPORTANT
Leakage into the duct or the C7232 box cover from
the room will skew the sensor readings. Ensure the
box cover and duct seal completely.
3. Place o-ring on tube end; mount the control to the tube.
