Process C, continued.
17. Cement as many sections and couplings of rigid 3/4" PVC
pipe needed to connect the 3/4" PVC adapter in the
discharge tee to the 3/4" male adapter on the tank tee inlet.
Set pressure in the diaphragm pressure tank to
2 pounds less than the cut-in pressure of the pump. The
cut-in pressure of these pumps is factory preset to 30 PSI. If
this cut-in setting has not been changed, then the diaphragm
pressure tank should be set to 28 PSI. Total installation
should look like the drawing at right.
18. Open a faucet or two in
REGULATOR
the house. Turn regulator STEM
adjustment screw down N
tight. Start motor. If pump
is properly primed, a high
pressure will immediately
show on the pressure gauge.
With pump operating at high
pressure, slowly unscrew
regulator stem until maximum
water flow is obtained without
dropping to zero. If pressure falls completely, retighten stem
and readjust. Steady pressure must not be less than
24 PSI for the FP4205 and 32 PSI for the FP4210. If no
pressure shows, stop motor, remove pressure regulator from
pump, add more water, and try again.
If you install your pump with a 2" slngle-pipe
("Packer") jet, please follow the installation
instructions included with the Packer jet kit.
[_WARNING] Risk of explosion. [f you change pressure
switch settings, set the cut-off pressure low enough to
shut off the pump. If a valve shuts off and the cut-off
setting is too high, the pump will run continuously
without water flow, causing overheating and possible
explosion which can cause serious burns and damage.
