4.1 – RECEIVING AND INSPECTION
• Carefully remove the Vari-Green Probe(s) or Station,
and Transmitter from the shipping container and
inspect for any damage. If any damage has occurred
in transit, contact freight carrier.
• Review the Factory Set-Up Information Sheet provided
separately and verify the W.O. # and Serial # match
those on the Vari-Green. Verify that the configuration
recorded on the Factory Set-Up Information Sheet
is correct for your application. If not, contact the
Greenheck dampers at 1-800-717-6540 for further
guidance.
Note: The Vari-Green has been configured to customer
provided parameters (see "Factory Setup Information
Sheet" provided separately), and requires no field
calibration/verification prior to installation.
4.2 – LOCATION
• The standard version of the Vari-Green Transmitter is
a NEMA 1 enclosure suitable for most clean indoor
locations. If additional protection is required, mount
the Transmitter in an enclosure with adequate NEMA
rating.
• The ambient temperature of the selected mounting
location must be between -20ºF to 140ºF.
Consideration should be given to units exposed to
direct sunlight.
