1INTRODUCTION AND SCOPE
This Quick Installation Guide provides basic installation information for the instrument installer. Information includes physical
instrument installation, power and output cable connections as well as initial setup of the instrument. Model GF-N1000 provides
a non-isolated RS-485 BACnet MS/TP or Modbus RTU output related to airflow and temperature.
Models covered in this document are include all GF-N1000 options as follows:
xAluminum or stainless-steel probe material
xProbe length (4 through 10, 12, 14, 16-inch lengths)
2GF-N1000 INSTALLATION
The GF-N1000 instruments are designed for use in small ducts and in VAV terminal box applications in an environment between
-20°F to 120°F (-28.9°C to 48.9°C) where it will not be exposed to rain or snow. The GF-N1000 airflow measurement station
sensor probes are designed for insertion mounting through one side of the duct or VAV box sidewall. Mount the instrument in an
accessible location to permit set up. Locate the instrument so that the customer provided power and network cables will reach
the instrument.
CAUTION
The installed location of the GF-N1000 is critical for proper performance. Refer to the
GteenTrol Minimum Placement Guidelines to determine the exact location
recommended for the instrument.
The installed accuracy of the GF-N1000 is ensured in applications where the maximum
inside duct dimension is 16 inches or less. Applications in larger duct sizes may
degrade accuracy. Consult factory for these applications.
Ensure that adequate clearance exists around the duct to permit insertion of the probe,
and to allow clearance for the instrument enclosure.
Insulation that interferes with probe mounting should be temporarily removed prior to
installation. Mounting requires a 0.875 inches (22.2 mm) hole on the insertion side of
the duct or VAV terminal box.
1.Determine where the GF-N1000 airflow measuring station is to be located as indicated on the engineer's plans.
2.Carefully open the GF-N1000 package and inspect for damage. If damage is noted, immediately file a claim with carrier.
3.Locate and mark the point on the duct or VAV box where the probe will be inserted, using the GteenTrol Minimum
Placement Guidelines. Figures 1 and 2 show GF-N1000 installation detail, probe orientation and dimensions.
4.Using a 0.875 inches (22.2 mm) hole saw, drill the insertion side hole where marked.
5.Place the probe through the mounting hole, making sure that the gasket is seated firmly against the integral mounting
bracket. Ensure that the edge of the GF-N1000 mounting bracket is parallel to the edge of the duct or VAV terminal box,
and that the airflow arrow printed on it is oriented in the direction of actual airflow. Ensure that the gasket is firmly
seated against the bracket, and then fasten the mounting bracket at the four mounting holes using appropriate sheet
metal screws.
