INSTALLATION TIP
The pressure switch supplied with ½ HP Jet Pumps is preset
to 20-40 PSI (pump turns on when system pressure drops
to 20 PSI - pump turns off when system pressure reaches 40
PSI). ¾ HP and 1 HP Jet Pumps are preset at 30 - 50 PSI.
If adjustments are necessary to fit your system needs,
follow the adjustment instructions on the inside cover of the
pressure switch. If you are using a precharged pressure tank
with your system, be sure that the empty tank pressure is
2 PSI lower than the cut in pressure setting of your pressure
switch. (See Section 7 - page 10)

Red Jacket convertible jet pumps can be adapted to the fol-
lowing deep well systems: 1) horizontally to a 3" or 4" double
pipe well seal (Figure 5); 2) horizontally to a vertical 2" well
adapter (Figure 6).
INITIAL PIPING IN A DEEP WELL
Step 1. On a deep well system similar to Figure 5, a foot
valve should be attached to a tail pipe ( a 5' to 10' length of
pipe attached to the bottom of the injector). The suction pipe
is larger than the drive pipe and should be the same size
at the tapped opening in the jet pump (1¼"). On deep well
systems similar to Figure 6, a 2" single pipe injector is used.
In this installation the well casing serves as the drive pipe.

Step 2. Before installation, single pipe injectors, packers,
should be soaked in water for at least two hours so the leath-
ers seat properly. Special turned couplings, order no. 64655,
are required for 2" injectors.
