F262 Series Airflow Switch Installation Instructions
Applications
The F262 Series Airflow Switch detects airflow or the absence of airflow by responding only to the velocity of air
movement within a duct. The switch can be wired to open one circuit and close a second circuit (SPDT) for either
signaling or interlock purposes.
Airflow failure during the normal operation of air handling systems may cause overheating, coil icing, or other
conditions that may be detrimental to the equipment.
Typical applications include:
• make-up air systems
• air cooling or heating processes
• exhaust systems
The switch has a Type 3R/IP43 enclosure with an integral mounting plate. A mounting plate gasket is supplied with
each control.
The enclosed SPDT PENN switch has color-coded terminals for ease of wiring. The control is factory set at
approximately the minimum flow rate. (See Table 1) It must not be any lower than the factory setting as this may
result in the control failing to return at a no-flow condition. If a higher flow rate setting is to be maintained, turn the
range adjusting screw clockwise.
The F262 switch can be mounted on the top, side, or bottom of a duct in a horizontal position whenever possible. If
vertical duct mounting is required and the flow is downward, the control setting must be readjusted. If the flow is
upward, refer to Table 1 for minimum flow required to actuate the control.
The switch is not designed for use where it is exposed to outside weather.
IMPORTANT: Use this F262 Series Airflow Switch only as an operating control. Where failure or malfunction of
the F262 switch could lead to personal injury or property damage to the controlled equipment or other property,
additional precautions must be designed into the control system. Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction
of the F262 switch.
IMPORTANT: Utiliser ce F262 Series Airflow Switch uniquement en tant que dispositif de régulation. Lorsqu'une
défaillance ou un dysfonctionnement du F262 switch l risque de provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs
de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que
des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction
d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du F262 switch.

Installation
Dimensions
Installation Procedure
Select the proper location. See Mounting.
1. Use the mounting plate gasket as a template and mark hole positions.
2. Drill or punch screw holes.
3. Cut the center hole large enough for the paddle to pass through.
4. Trim the paddle, if necessary (see Figure 2).
• The standard paddle fits into ducts of
3 in. × 8 in. (76 × 203 mm) minimum.

• The paddle may be trimmed for installing in ducts as small as 3 in. × 6 in.
(76 × 152 mm).
Mounting
The F262AA switch can be mounted on the top, side, or bottom of a duct.
• Mount the switch in a horizontal duct whenever possible. In a horizontal duct, the switch housing must be level,
and the paddle should be at approximately a right angle to the air flow.
• When mounting the switch in a horizontal duct that is not horizontally true, check with a level and place a shim
under the switch mounting plate. Do not mount the switch without a shim (see Figure 4).
IMPORTANT: Mount the switch so that the housing is level horizontally (or plumb vertically). Use a shim, if
necessary.

• When mounting the switch in a vertical duct where the airflow is upward (Figure 5), see Table 1 for the
minimum flow required to actuate the switch. The maximum air velocity should not exceed
2,000 FPM (10.16 m/s).
• When mounting the switch in a vertical duct where the airflow is downward (Figure 5), adjust the switch:
a. Turn the adjusting screw (Figure 6) clockwise until the switch closes the circuit between the red and blue
terminals when there is no air flow.
b. Turn the adjustment screw one additional turn clockwise.

Location Considerations
Do not use this switch where it is exposed to outdoor weather. The switch is designed specifically for indoor use.
Avoid locations close to elbows, dampers, fans, duct openings, or other areas where excessive turbulence occurs.
Mount the switch away from such areas at least five times the distance of the smallest duct dimension (Figure 7).
Example: On a 3 in. × 8 in. duct, mount the F261 at least 15 in. (381 mm) from the nearest bend.
IMPORTANT: Mount the switch so that the housing is level horizontally (or plumb vertically). Use a shim, if
necessary.

Wiring
The terminals are color coded. Red is common. See Figure 8 for switch action.
The circuit between the red and yellow terminals closes when the required airflow velocity is reached within the
duct where the switch is installed.
An indicator light or signal, when connected to the blue terminal, activates when the airflow decreases or ceases.
!
WARNING: Risk of electric shock
Disconnect the power supply before making electrical connections. The printed circuit board and its
components are at AC line voltage. Contact with components carrying hazardous voltage can cause
electric shock and may result in personal injury or death.
AVERTISSEMENT : Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout raccordement électrique. Le circuit imprimé et ses
composants présentent une tension CA. Tout contact avec des composants porteurs de tensions
dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire
mortelles.
IMPORTANT: Use the terminal screws provided (M4 x 8 crosshead). Substitution of other screws voids the
warranty and agency approvals.
IMPORTANT: Use copper conductors only. Make all wiring connections in accordance with local, national, and
regional regulations. Do not exceed the device’s electrical ratings.

Setup and Adjustments
To adjust the setting of the flow switch:
1. Disconnect the power supply before making any electrical connections.
2. Remove the enclosure cover.
3. Adjust the switch’s flow rate (Figure 9):
• Turn the adjustment screw counterclockwise to lower the flow rate required to activate the switch.
• Turn the adjustment screw clockwise to raise the flow rate required to activate the switch.
Note: Do not lower the flow rate required to activate the switch, unless the flow rate required to activate the
switch was raised from the factory-set flow rate.
4. Replace the enclosure cover and tighten the cover screws with 12 in•lb of torque.
!
CAUTION: Risk of property damage.
Do not set the switch lower than the factory setting. The switch is factory set at approximately the
minimum flow rate. A lower setting may result in the switch failing to return to a no-flow position which
may result in damage to the controlled equipment or other property.
MISE EN GARDE : Risque de dégâts matériels.
Ne pas régler le commutateur sur une valeur inférieure au paramètre d'usine. Le commutateur est réglé
en usine sur une valeur correspondant environ au débit minimum. Un réglage sur une valeur inférieure
risque d'empêcher le commutateur de revenir sur une position « aucun-débit », ce qui risque
d'endommager l'équipement contrôlé ou de provoquer d'autres dégâts matériels.
!
CAUTION: Risk of property damage.
Do not attempt to change sealed settings (screws marked with black paint). Attempted adjustment may
damage the switch or cause loss of calibration or other property damage.
MISE EN GARDE : Risque de dégâts matériels.
Ne pas essayer de modifier la position des éléments de réglage bloqués (vis identifiées par de la
peinture noire). Toute tentative de réglage risque d'endommager le dispositif de contrôle ou de
provoquer la perte des valeurs d'étalonnage ou d'autres dégâts matériels.

Table 1 shows airflow velocities in FPM required to activate the switch for any given duct size (horizontal or vertical
upward flow). The flow rate table is based on a standard air density of 0.075 lb/ft3[1.2 kg/m3].
Checkout Procedure
The circuit between the red and yellow terminals closes when air flows through the duct (where the switch is
located) at the required velocity. When connected to the red and blue terminals, the warning light or signal activates
when the air flow decreases or ceases.
Before leaving the installation, observe at least three complete operating cycles to be sure that all components are
functioning correctly.
