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 signalling 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 PENNswitch has color-coded
terminals for ease of wiring. The control is factory set at
approximately the minimum flow rate. (SeeTable 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 alevel and place
a shim under the switch mounting plate. Do not
mount the switch without a shim (see Figure 4).
• 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.
IMPORTANT: Mount the switch so that the housing
is level horizontally (or plumb vertically). Use a shim,
if necessary.

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.
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.
IMPORTANT: Mount the switch so that the housing
is level horizontally (or plumb vertically). Use a shim,
if necessary.

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 yellowterminals 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.

Repair Information
Do not make field repairs, except for replacement of
