Penn F261 Series Installation Manual

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.
F261 Series Flow Switches Installation Guide
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.
