Typical applications include:
- Make-up air systems
- Air cooling or heating processes
- Exhaust systems
The airflow switch includes a Type 3R (NEMA) enclosure with an integral mounting plate. A mounting plate gasket is supplied with each airflow switch.
The SPDT Pennswitch includes color coded terminals for ease of wiring. The airflow switch is factory set at approximately the minimum flow rate, see Table 1. Do not set the switch any lower than the factory setting, or it may fail to return to a no-flow off condition. To maintain a higher flow rate setting, turn the range adjusting screw clockwise.
Mount the F262 Series Airflow Switch on the top, side, or bottom of a duct in a horizontal position whenever possible. If you require vertical duct mounting and the flow is downward, you must readjust the airflow setting. If the flow is upward, see Table 1 for the minimum flow required to actuate the control.
The control is not designed for use where it is exposed to outside weather.
