repeat cycle is provided, allowing time-based, as well as gas-
based fan activation. In both modes of fan control, the “on”
time is user-adjustable 1 to 8 minutes in one minute increments.
For optimum performance, install, burn-in, calibrate and check
out your TOXALERT exactly as instructed. If your
TOXALERT can’t be calibrated or fails checkout, please
contact your local representative or TOXALERT
International for servicing.
2. INSTALLATION
Refer to figures 1, 2 and 3, and install and connect the
TOXALERT sensors and control units as follows:
GVU-CO SENSING UNITS
1) Open the door using the key provided. 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 vertically 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 burrs from enclosure.
6) Place the cover onto the hinges of the base.
See separate data sheet for installation instructions of
GVU-CO2, GVU-NO2 and GVU-VOC.
