F262 Series Airflow Switch Installation Guide
Applications
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 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.
The F262 Series Airflow Switch detects airflow or the
absence of airflow only in response to the velocity of air
movement within a duct. You can wire the switch to open
one circuit and close a second circuit, single-pole, double-
throw (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.
You must not set the control any lower than the factory
setting because the control may fail to return to a no-flow
condition. If you require a higher flow rate setting, turn
the range adjusting screw clockwise.
Mount the F262 switch 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, you
must readjust the control. 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.

Installation procedure
Before you begin:
Select the proper location. See Mounting.
1. Use the mounting plate gasket as a template and
mark the hole positions.
2. Drill or punch the 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 mm × 203 mm) minimum.
- You can trim the paddle for installation in
ducts as small as 3 in. × 6 in. (76 mm × 152
mm).

Mounting
Important: Mount the switch so that the housing is
level horizontally, or plumb vertically. Use a shim, if
necessary.
You can mount the F262AA switch on the top, side, or
bottom of a duct.
• Mount the switch in a horizontal duct whenever
possible. In a horizontal duct, make sure that the switch
housing is level and the paddle is at approximately a
right angle to the air flow.
Figure 3: Mounting the F262 Switch in a horizontal duct
• When you mount 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 the following figure.
Figure 4: Mounting the F262 Switch in an angled duct
• When you mount the switch in a vertical duct where
the airflow is upward as shown in the following figure,
see Table 1 for the minimum flow required to actuate
the switch. The maximum air velocity must not exceed
2,000 fpm (10.16 m/s).
Figure 5: Mounting the F262 control in a vertical duct
• When you mount the switch in a vertical duct where the
airflow is downward as shown in the previous figure,
adjust the switch:
a. Turn the adjustment screw clockwise until the
switch closes the circuit between the red and
blue terminals when there is no air flow. See the
following figure.
b. Turn the adjustment screw one additional turn
clockwise.
Figure 6: F262 Switch action
Location considerations
Important: Mount the switch so that the housing is
level horizontally or plumb vertically. Use a shim, if
necessary.
Do not use this switch where exposure to outdoor
weather occurs. Use the switch only for indoor situations.
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 as shown in
the following figure.
Example: On a 3 in. × 8 in. duct, mount the F261 at least
15 in. (381 mm) from the nearest bend.

Wiring
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 M4 x 8 crosshead terminal screws
provided. Substitution of other screws voids the
warranty and agency approvals.
• Use copper conductors only. Make all wiring
connections in accordance with local, national,
and regional regulations. Do not exceed the
device’s electrical ratings.
The terminals are color coded. Red is common. See the
following figure for switch action.
Figure 8: F262 control switch action
On an installed switch, the circuit between the red and
yellow terminals closes when the required airflow velocity
is present within the duct.
When you connect an indicator light or signal to the blue
terminal, the light or signal activates when the airflow
decreases or ceases.
Setup and adjustments
Before you begin:
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.
ATTENTION
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.
ATTENTION
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.

Note: Do not lower the flow rate required to
activate the switch unless it is set above the
factory set flow rate.
4. Replace the enclosure cover and tighten the cover
screws with 12 in•lb of torque.
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 you connect 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 make sure that all
components function correctly.
