F261 Series Flow Switches Installation Guide
Applications
Important:
• Do not install or use this F261 Series Flow Switch in
or near environments where corrosive substances
or vapors could be present. Exposure of the F261
Series Flow Switch to corrosive environments may
damage the device’s internal components and will
void the warranty.
• Do not use F261 Series Flow Switches where the
fluid in the pipes drops below the fluid’s freezing
point, causing an internal freeze-up.
Important: Use this F261 Series Flow Switch only as
an operating control. Where failure or malfunction
of the flow 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
flow switch.
Important: Utiliser ce F261 Series Flow Switch
uniquement en tant que dispositif de régulation.
Lorsqu'une défaillance ou un dysfonctionnement
du flow 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 flow switch.
WARNING
Risk
This product is made of a copper alloy, which contains
lead. The product is therefore not to be used on
drinking water.
The F261 Series Flow Switches respond to fluid flow in lines
carrying water, ethylene glycol, or other nonhazardous
fluids. These models also work in applications with
swimming pool water and lubricating oils.
F261 Series Standard Flow Switches use a variety of
paddle sizes to respond to fluid flow rates in applications
with 1 inch trade size (or greater) pipe.
F261 Series Low Flow Switches respond to low fluid flow
rates in applications with 1 inch trade size (or less) pipe.
A low-energy model with gold-plated contacts provides
improved electrical performance in low-voltage, low-
current circuits to operate small relays, solenoid valves,
and electronic control circuits.
Installation
F261 Series Standard Flow Switches come with 1 in., 2 in.,
3 in., and 6 in. stainless steel flow paddles, a paddle screw
and a lock washer. For replacement parts, see Table 2.

Installing the flow paddles
Before you begin:
WARNING
Risk of personal injury.
Shut off the liquid supply and relieve pressure in the
line before servicing the valve. Contents of liquid lines
could be under pressure and the release of liquid
under pressure may cause severe personal injury.
AVERTISSEMENT
Risque de blessure.
Couper l'arrivée de liquide et évacuer la pression
présente dans la conduite avant toute intervention
sur la vanne. Les liquides à l'intérieur des conduites
peuvent être sous pression et la libération soudaine
de liquide sous pression risque de provoquer des
blessures graves.
To install the flow paddles, complete the following steps:
1. Check if one of the flow paddles corresponds to the
pipe diameter. Leave a minimum clearance of 3/16
in. (5 mm) between the end of the flow paddle and
the pipe wall.
Important: Do not install the flow paddle
in such a way that it touches the pipe or any
restrictions in the pipe. If the flow paddle
touches the pipe or restrictions in the pipe, the
switch may not correctly detect changes in fluid
flow.
2. If necessary, trim a larger flow paddle at the arc
corresponding to the pipe diameter.
For trimming information, see Figure 3, Table 1,
and Figure 6.
3. Use the flow paddle screw to install all flow paddles
that fit. Remove flow paddles that are too large to
fit the pipe diameter.
For flow paddle installation information, see
Figure 4.

Mounting
Figure 5: Wrench usage
Important:
• Use only the wrench flats provided.
• To avoid damaging the switch, do not tighten
the switch to the tee by grasping the switch
enclosure.
To mount the F261 Series Flow Switches, observe the
following guidelines:
• Install the switch so that the enclosure and interior are
accessible.
• Mount the switch so that the flow of the fluid is in the
direction of the arrow on the enclosure.
• Use a pipe union on each side of the flow switch to
allow for easy removal or replacement.
• Do not allow the pipe to extend too far into the flow
switch casing.
• Use pipe thread sealer or Teflon® tape on the male
threads only.
• Do not remove the case-to-cover O-ring on Type 4/IP67
enclosures.
Figure 6: Trimming diagram for the large flow paddle
For standard 1 in. x 1 in. pipe installation, mount the F261
flow switch in a standard 1 in. x 1 in. x 1 in. tee. For larger
sizes of pipe, use a reducing tee to keep the flow switch
close to the pipe and provide adequate paddle length in
the flow stream.
Example: Use a 2 in. x 2 in. x 1 in. tee for a 2 in. pipe. If you
use a standard 2 in. x 2 in. x 2 in. tee, install a face or hex
bushing in the top opening to reduce the top opening to 1
in.
F261 Series Flow Switches Installation Guide4

Location considerations
Figure 7: Flow direction for vertical mounting
Important: Do not use the F261 flow switch in a
vertical pipeline with a downward flow.
Mount the F261 flow switch in a horizontal pipeline or a
vertical pipeline with upward fluid flow. When you mount
the switch in a vertical pipe with an upward flow, it trips at
a slightly higher flow than in Table 7 and Table 8, due to
the effect of gravity on the switch mechanism.
Mount the F261 flow switch in a section of pipe where
there is a straight run of at least five pipe diameters from
the nearest elbow, valve, or other pipe restriction. See
Figure 8.
Figure 8: Required piping distance

C Tee or welded half-coupling
When you mount the flow switch on a horizontal pipe,
mount the flow switch within 60 degrees of vertical. See
Figure 9.
Figure 9: Correct flow switch angle
Note: Do not subject the flow switches to water
hammer. Use a suitable water hammer arrester if
a fast-closing valve is located downstream of the
switch. See Figure 10.

Setup and adjustments
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. Attempted
adjustment may damage the control 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. 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.
To adjust the setting of the flow switch:
1. Disconnect the power supply before making any
electrical connections.
2. Remove the enclosure cover.
F261 Series Flow Switches Installation Guide6

3. Adjust the control’s flow rate. For more information,
see Figure 12.
- Turn the adjustment screw clockwise to raise
the flow rate required to activate the switch.
- Turn the adjustment screw counterclockwise
to lower the flow rate required to activate the
switch.
Figure 12: Flow Rate Adjustment

to activate the switch, unless the flow rate
required to activate the switch is above the
factory-set flow rate.
4. Replace the enclosure cover and tighten the cover
screws with 12 in•lb of torque.
To verify that the flow rate is set above the factory
minimum, depress the main lever multiple times. For
more information on the main lever, see Figure 13.
• If the lever clicks every time when returning to the
original position, then the control’s flow rate may be
set at or above the factory-set minimum value.
• If the lever fails to click every time when returning to
the original position, then the control’s flow rate is set
below the factory-set minimum value.
Turn the adjustment screw clockwise to raise the flow rate
required to activate the switch. See Figure 12.

Troubleshooting
Table 11: Troubleshooting
Symptom Solution
Condensate water
appears within the
enclosure.
If the control has a Type 3R/IP43
enclosure, inspect the grommet
in the field-installed cable gland
or conduit fitting, and replace the
grommet if it is defective.
If the control has a Type 4/
IP67 enclosure, inspect the
case-to-cover O-ring provided
on the flow switch. Ensure
that the O-ring is in place and
undamaged. Ensure that the
control uses a correct cable
gland or conduit fitting for Type
4/IP67 applications.
Fluid from the
tank leaks into the
enclosure due to a
rod seal failure.
Replace the flow switch.
The switch does
not activate due to
debris in the switch
mechanism.
Clear any debris from within
the switch mechanism. Test the
operation of the switch several
times for correct operation.
The control switch
action is reversed.
Ensure that the connections
follow the wiring diagrams.
Table 11: Troubleshooting
Symptom Solution
The control does not
switch.
Check the electrical connections.
The switch fails to
return to the no-flow
