INSTALLATION INSTRUCTION:
(Reference Technical Bulletin ANA-Applications)
The Tox-CO/ANA is designed to allow mounting and wiring of the base prior to installation of sensor
electronics. The electronics are cabinet door mounted and when door is opened it may be slipped on/off
of the hinges, and the wiring harness may be unplugged from the cabinet base allowing for easy and
complete removal of the electronics assembly from the base. This unique design allows cabinet base
installation and wiring without subjecting the sensor to harsh construction dust, dirt or physical abuse.
With power wiring installed and checked out, the sensor(s) can then be mounted, connected, and in-
stalled.
1.) Open the door using the key provided. Disconnect the cable plugged into the electronics in the door
labeled J2. Next lift off the front door by sliding it up the pins of the hinges. Put it aside.
2.) Locate a mounting location away from drafts, away from direct fresh air intakes, and mount verti-
call on wall or support column approximately 5 to 6 feet above floor.
3.) Mount base with hinge pins along left side by using mounting holes (4 are available).
4.) A wiring access hole must be added to the base anywhere around the bottom, or right side. Do not
place an access hole on the hinge side of the base, since, if conduit is used, this may restrict the
opening of the door. If conduit is to be used, use a chassis punch to match the required fitting size.
5.) Remove any metal chips and/or burrs from enclosure.
