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.

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.
Important: The flow paddle must not touch the pipe or any restrictions in the pipe. If the flow
paddle touches the pipe (or restrictions in the pipe), the switch may not be able to properly
detect changes in fluid flow.
Adjust the flow paddles to the size of the pipe used. Install the large flow paddle, if needed. Trim
the flow paddle at the arc corresponding to the pipe size. See Figure 3, Figure 4, Figure 6, and Table
1.

Mounting
Figure 5: Use Only the Wrench Flats Provided
Important: To avoid damaging the switch, do not tighten the switch to the tee by grasping the
switch enclosure. Use only the wrench flats provided.
Mount the F261 Series Flow Switches using 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.

For standard 1 in. x 1 in. pipe installation, mount the F61 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 a standard 2 in. x 2 in. x 2 in. tee is used,
install a face or hex bushing in the top opening to reduce the top opening to 1 in.
Location Considerations
Figure 7: Flow Direction for Vertical Mounting
F261 Series Flow Switches Installation Guide6

Important: Do not use 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 mounted in a vertical pipe with an upward flow, the switch trips at a slightly higher flow than
shown in Table 4 and Table 5, 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
When mounting the flow switch on horizontal pipe, mount the flow switch within 60 degrees of
vertical. See Figure 9.
Figure 9: Angle Allowed
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.

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 terminal screws provided (M4 x 8 crosshead). Substitution of other screws voids the
warranty and agency approvals.
• To prevent moisture from entering and condensate from forming inside the Type 3R/IP43
enclosure, do not block the drain hole provided.
• To prevent moisture from entering and condensate from forming inside the Type 4/IP67
enclosure, do not remove the case-to-cover O-ring provided on the flow switch.
• Use copper conductors only. Make all wiring in accordance with local, national, and regional
regulations.
• Do not exceed the control’s electrical ratings. Exceeding the control’s electrical ratings can
result in permanent damage to the control and void any warranty.
The F261 models have three color-coded terminals. Red is common. See Figure 11 and Table 3 for
switch action.

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.
9F261 Series Flow Switches Installation Guide

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.
3. Adjust the control’s flow rate (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
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.
To verify that the flow rate is set above the factory minimum, depress the main lever (see Figure 13)
multiple times:
• 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 8: Troubleshooting
Symptom Solution
Water (condensate) 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 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.
Switch does not activate due to
debris in switch mechanism.
Clear any debris from within the switch mechanism. Test the
operation of the switch several times for proper operation.
Control switch action is reversed. Ensure connections follow wiring diagrams.
Control does not switch. Check the electrical connections.
Switch fails to return to the no-flow
position.
The switch may be set lower than the factory setting. Increase the
setting.
On vertical pipes, ensure that the direction of flow is up. The arrow
on the switch enclosure must point in the direction of the flow.
Control does not switch on flow
increase.
Check for a cracked or broken paddle. Replace the paddle, if
necessary.
