Operation
Unit must be full of
fl uid before
operating. Do not run dry or against a
closed discharge. Do not pump dirty water
or abrasive liquids. To do so will cause the
pump failure and will void the warranty.
VALVES
The inlet and outlet isolation valves
should be in the full open position.
PRIMING
NOTE: Before starting the pump it
is absolutely necessary that both
the pump and the inlet pipe be
completely fi lled with water.
PRESSURE BOOST INSTALLATIONS
Priming is automatic when pump is
connected to a pressure source such as a
hydrant or city main. (See Figure 3).
1. Open valves or nozzle on inlet and
discharge side of pump.
2. Open a faucet nearest the booster
unit. Plug pump into outlet. When
the water fl ow from the faucet
reaches one gallon per minute, or
greater, the pump will automatically
start. Keep the faucet open for
approximately 30 seconds to relieve
trapped air in the line. When the
faucet is closed, the pump will
continue to run until pressure
reaches 60 psi.
The pressure switch
is factory set at 50
psi and must not be changed.
3. If you installed a pressure gauge at
the pump inlet, a reading of 2 psi
minimum should show whenever the
pump is in operation. This reading
ensures that there is an ample supply
of water into the pump inlet housing.
4. The controller, fl ow sensor and
pressure switch continuously
monitor water pressure and fl ow.
The system automatically turns the
unit off if pressure reaches 50 to
53 psi. The control package also
protects the unit from dry run by
shutting down if water usage drops
below 1 gallon per minute.
MOTOR/PUMP ROTATION
1. The motor rotates in a counter
clockwise rotation when facing the
pump end and cannot be reversed.
START-UP PROCEDURE
Once the preceding instructions have
been completed, the unit is ready for
normal operation.
1. During the fi rst few hours of
operation, inspect the pump, piping
and any auxiliary equipment used in
connection with the unit for leaks,
excessive vibration or unusual noises.
2. The booster unit will turn on and
off automatically, based on water
usage.
Maintenance
Disconnect power
and release all
pressure from the system before
attempting to install, service, relocate
or perform any maintenance. Lock the
power disconnect in the open position.
Tag the power disconnect to prevent
unexpected application of power.
Protect the pump
from freezing during
winter conditions.
DRAINING THE PUMP
Drain openings are provided on all
models. To drain the pump:
1. Remove drain plug and prime plug
to vent the system.
REMOVING OLD SHAFT SEAL
Turn disconnect switch
to “off” position.
1. Open a faucet nearest the tank and
allow all water to drain from the
tank.
2. Remove the four cap screws holding
the pump housing (volute) to the
motor (Figure 4).
