factory preset to 30 PSI. Reset the pressure to 18
PSI using a tire gauge. This is vital to the proper
operation of the system. Remove pressure gauge plug.

INSTALLATION

CAUTION: If you change pressure switch settings,
set the cut-off pressure low enough to shut off the
pump. The recommended pressure is 2 PSI below
your pump cut-off pressure. Example: if a 20-40 PSI
pressure switch is being used, tank pressure should
be 18 PSI. If a valve shuts off and the cut-off setting
is too high, the pump will run continuously without
water flow causing overheating and serious damage.
ed without pressure dropping to zero. If pressure falls
completely, retighten adjustment screw and re-adjust.
Steady pressure must not be less than 24 lbs. for the
R520 and 32 lbs. for the R100. If no pressure shows:
Stop motor, remove pressure gauge plug from pressure
regulator, add more water, and try again. Complete
installation should look like the drawing to the right.
Place a large bucket
beneath the pressure
regulator outlet. Start
motor. Turn regulator
adjustment screw down tight.
If pump is properly primed a
high pressure will immediately
show on the pressure gauge.
With pump operating at high
pressure, slowly unscrew reg-
ulator adjustment screw until
