INSTALLATION PROCEDURE
*WARNING: EXPLOSION HAZARD – SUBSTITUTION OF COMPONENTS MAY
IMPAIR SUITABILITY FOR CLASS 1, DIVISION 1.
STEP 1: Choose a location for mounting the flow switch in the water supply line. The inlet
and outlet ports of the flow switch must be a minimum of 6 inches from any tees
or elbows in the water supply line. See attached installation drawing.
STEP 2: Mount the flow switch assembly in the water supply line. The switch body must
be in the vertical position with the water pipe horizontal. The water flow must be
in the direction marked by the arrow on the flow switch body. Use pipe sealing
compound on all water pipe connections.
STEP 3: Choose a location for mounting the alarm assembly. The alarm housing should
be positioned along a vertical axis at least 7 feet above ground for best visibility.
The alarm may be mounted directly to a water pipe using the supplied brackets.
The alarm can also be bolted to a flat surface such as a wall, using flanges with
appropriate fasteners (not supplied).
STEP 4: Using wire nuts, connect the flow switch to the alarm and power. The pink and
orange wires are connected to the second normally closed contact of the flow
switch and may be used for remote alarm activation. The signal from the pink
wire will be supply voltage, to be provided to orange wire by customer, when no
water is flowing and zero voltage when the flow switch and local alarm are
activated. If a remote alarm is not used, the pink and orange wires must be
insulated at their free ends. Power to be routed using rigid conduit and a seal
fitting or Class 1, Division1 rated armored cable and an appropriate gland fitting.
See Electrical Wiring Diagram provided on installation drawing. Follow all
instructions in installation drawing and NEC code when installing unit.
