JD_ _F units are
custom built for
each application.
The minimum SG
of any unit is
specific to the
application and
final design, based
on the float, the
elevation of the
switch trip point,
and the switch
being used.

Switching Point Adjustment
Each switch mechanism is mounted on a bracket, which is secured on the pressure tube by a locking screw and lock nut.
These can be loosened, allowing the bracket, and therefore the switch trip point elevation, to be adjusted up or down as
required. Always ensure that the small pressure plate between the locking screw and the pressure tube is in place before
re-tightening the locking screw nut.
Each switch, unless otherwise ordered, is assembled with factory default switch trip points, for the minimum specific gravity
(SG) of the unit. Higher application SG’s will cause the switch to trip sooner, at a lower elevation. Any change made to the
factory default switch positions are done at the customers discretion, and should be tested in the application fluid to ensure
that each switch mechanism can be tripped and also reset.
