Installation
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 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 123355 and 32 PSI for the 123353. 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" single-pipe
("Packer") jet, please follow the installation
instructions included with the Packer jet kit.
Notice: Plastic shipping base is attached to prevent movement in shipment only.
Do not return pump if shipping base becomes cracked in shipment,
For parts or assistance, call Master Plumber Customer Service at 1-800-628-9439
as pump performance will not be affected.
WARNING: 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.
** Requires FP520-100-P2 ejector (sold separately).
