Johnson Controls F61 Series Installation Instructions Manual

F61 Series Standard Flow Switches
Installation
IMPORTANT: All F61 Series Flow Switches are
intended to control equipment under normal
operating conditions. Where failure or malfunction of
an F61 Flow Switch could lead to an abnormal
operating condition that could cause personal injury
or damage to the equipment or other property, other
devices (limit or safety controls) or systems (alarm or
supervisory) intended to warn of, or protect against,
failure or malfunction of the F61 Flow Switch must
be incorporated into and maintained as part of the
control system.
Some models of the F61 Series Standard Flow
Switches require installation or adjustment of paddles
prior to mounting. See Installing the Flow Paddles.
Parts Included
Standard models of the F61 flow switch include an
installed three-piece flow paddle. Some models also
include a large flow paddle for large pipe sizes.

Installing the Flow Paddles
IMPORTANT: To allow the switch to detect changes
in the fluid flow, the flow paddle must not touch the
pipe or any restrictions in the pipe.
Adjust flow paddles to the size of the pipe used. If
needed, trim the large flow paddle at the arc
corresponding to pipe size (see Figure 1 and Figure 2)
and install.
