INSTALLATION & OPERATION
17. Cement as many sections and couplings of rigid 3/4"
PVC pipe needed to connect the 3/4" PVC adapter in the
pressure regulator to the 3/4" male adapter on the tank tee
inlet. Set pressure in the pre-charged pressure tank to 2
pounds less than the cut-in pressure of the pump. If the cut
in pressure is 30 PSI, then the correct tank pre-charge is
28 PSI. If the cut in pressure is 20 PSI, then the correct tank
pre-charge is 18 PSI. Total installation should look like the
drawing at right.
18. Open a faucet or two in the house. 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 regulator
stem until maximum water
flow is obtained without
dropping to 0 PSI. If pressure
falls completely, retighten
stem and readjust. Steady
pressure must not be less
than 24 PSI for the FP4542 and 32 PSI for the FP4562.
If pressure fails to build within five minutes: stop motor,
remove pressure regulator from pump, add more water,
and try again.
If you install your pump with a 2" single-pipe ("Packer") jet,
please follow the installation instructions included with the
Packer jet kit (See REPAIR PARTS KIT).
Risk of explosion. If 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.

PRIMING THE PUMP
1.
Open tank drain valve or a few faucets to relieve any water
pressure in system.
2.
Remove pressure gauge plug from discharge tee OR remove
pressure regulator.
3.
Put a garden hose into pump opening and fill pipes and
pump until water overflows from opening. This may take
several minutes.
4.
After wrapping threads with PTFE pipe thread sealant tape
tape, replace pressure gauge plug OR pressure regulator in
pump housing.
