INSTALLATION STEPS
Step 1. FOR YOUR SAFETY turn off electrical
WARNING
power supply at the service entrance before connecting
or disconnecting any wiring to the pump to avoid any
possible electrical shock hazard.
Step 2. Drain the holding tank. Also disconnect the drive
pipe and the suction pipe, the service line, and if necessary,
the volume control line. Remove old pump.
Step 3. Place the jet pump on a level, solid foundation. If
you are also replacing the existing pressure tank, refer to
Section 7 in this manual.
Step 4. Connect the drive pipe and suction pipe, the
service line and, if necessary, the air volume control line.
Use either non-toxic pipe sealing compound or tape on
male thread joints of galvanized pipe (tape or cement on
plastic pipe) to facilitate making air tight joints.
Step 5. Wire the motor.
The Red Jacket convertible jet pump is wired to the
pressure switch. The pressure switch must be grounded in
compliance with the National Electrical Code and state and
local codes and ordinances. It is mandatory that a ground
connection be made using a conductor or appropriate
metal underground water pipe or a ground lead in the
service panel.

WARNING
grounding plug do not remove round grounding prong
since it must be plugged into a grounded receptacle to
assure proper grounding.
Direct wiring instructions can be found on the inside cover
of your pressure switch.
Step 6. Prime the Pump
A. Remove the manual regulator.
B. Pour water into the pump case until it flows freely out
of the priming hole without air bubbles.
C. Turn the regulator adjusting screw counter-clockwise
until stem travel stops, or regulator poppet is near
valve bushing end. Replace regulator.
D. Turn the adjusting screw in a clockwise direction until
it is all the way in.
E. Open faucets on the downstream side of the pressure
tank to bleed off air.
F. Turn power on. Start pump. The pump should start
showing pressure on the pressure gauge.
G. To adjust the regulator, slowly turn the adjusting
screw in a counter-clockwise direction until the
pressure gauge fluctuates rapidly or the pump
becomes noisy. At this point, turn the screw clockwise
until gauge pressure holds steady.
H. Close all faucets on the downstream side. Sufficient
pressure should build up and shut the pump off.
