WIRING
Use properly rated temperature supply wire for
the anticipated service temperature.
Make all electrical connections in accordance
with the National Electrical Code and local regu-
lations.
See Figs. 6A and 6B for diagrams illustrating
switch action.
ADJUSTMENT
Remove switch cover and turn the sensitivity
adjusting screw clockwise to increase the flow
rate required to actuate the switch. Turn the
sensitivity adjusting screw counter-clockwise to
decrease the flow rate required to actuate the
switch. (See Fig. 1.) Be sure to replace the
cover upon completion of the installation and
adjustment.
CAUTION:
Check the installation for "no-flow"
switch operation. Make appropriate adjustments
to the sensitivity adjustment screw to be sure the
switch restores fully at the desired flow rate.
NOTES:
1. Typical flow rates for 1" to 1 1/2" pipe sizes
are averages which may vary approximately
±1 GPM with the use of a bronze reducing
tee.
2. Typical flow rates for 2" to 8" pipe sizes are
averages which may vary ±10% with the use
of a 1" weldolet.
(*) Flow rates for these sizes are calculated.
