SECTION 6: PRESSURE SWITCH MOUNTING AND WIRING
For connection to a pump, locate the two pressure
switch mounting holes on the pump frame. If
replacing an old pressure switch, you may need to
drill two holes in the pump frame (7/32" dia.
approximately 13/16" apart).
FIGURE 7: Pressure Switch Mounting Holes
Using hardware included, mount the switch to the
pump frame. Thread the barbed fitting into the
threaded hole at the pump inlet. Cut the silicone
tube to the appropriate length to eliminate the
possibility of kinks and securely attach the hose to
the pressure switch and the barbed fitting.
