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