Installation
(Continued)
Do NoT use both
a check valve and
foot valve in your system. This CouLD
significantly reduce the performance of
the pump.
DRIlleD Well
1. Install a foot valve on the first
section of pipe (Figure 10).
2. lower the pipe into the well.
3. add pipe until the foot valve is 10
feet below the lowest anticipated
water level.
leaking joints or couplings will allow
air to leak into the pipe and cause poor
pump operation. Make sure to use pipe
joint compound or plumbers seal tape
on all pipe connections.
Locate foot valve at
least 2 feet from
the bottom of the well so sand or
sediment is NoT drawn into the system.
4. after proper depth is reached, install
a well seal or pitless adapter to
support the pipe.
5. Slope the horizontal pipe upward
toward the pump to eliminate
trapping air.

InStallatIon
1. Install a foot valve on the inlet pipe
and lower into the water.
Locate foot valve
at least 2 feet
from the bottom of the well so sand or
sediment is NoT drawn into the system.
NOTE: When a lake is used for the
water supply, make sure the suction
pipe is deep enough to be submerged
at all times. Slope the pipe upward
toward the pump to eliminate trapping
air. the pipe must be removed during
winter months or protected against
freezing.
Protect the pipe
!
WARNING
from damage by
swimmers and boaters.
Operation
PrIMING PUMP
Do NoT run pump
dry. Fill with water
before starting motor. Damage to pump
seals WILL result and void warranty.
after pump installation is complete, the
pump must be primed.
1. Remove the priming plug.
2. Fill pump and piping completely full
of water.
3. Replace the priming plug.
4. open faucet to vent system.
5. Start the motor. Water will be
pumped within a few minutes. If
pump does not deliver water within
5 minutes, shut off motor and return
to step 1.
6. let the system operate for several
minutes to flush out the pipes.
7. Close the faucet and allow pump
to build pressure in the tank. When
pressure reaches cut-out setting, the
motor will stop.
the system is now operating and will
cycle on demand.
If the pump does not operate after
repeated attempts, check the following:
1. Vertical distance of pump to water
must not exceed 25 feet.
2. Suction piping must be air tight.
3. Be sure valves are open if used in
discharge or suction piping.
NEvER run the
pump with a closed
or clogged discharge. The water inside
the pump CouLD boil and damage the
pump.
the use of a foot valve is strongly
recommended. this allows the suction
line to be filled during the priming
process, greatly decreasing priming
times.
Maintenance
Disconnect power supply
and release all pressure from
system before attempting
to install, service, relocate, or perform
any maintenance. Lock the power
disconnect in the open/off position.
Tag the power disconnect to prevent
unexpected application of power.
Serious injury or death CouLD result.
Maintain adequate ventilation for the
pump motor. the motor bearings are
permanently lubricated at the factory.
additional lubrication is not required.
DraINING PUMP
Drain openings are provided on all
models. to drain the pump:
1. Disconnect power to the pump
2. Remove the drain fitting and
priming plug.
3. Drain all piping to a point below the
frost line.
DraINING TaNK
Conventional tanks can be drained by
opening an outlet at the lowest point
in the system. Remove a plug or the air
volume control to vent the tank.
Pre-charged tanks force virtually all
of the water from the tank when the
system pressure is released. no draining
is necessary.
waTEr-lOGGED TaNKS
ConVentIonal tanKS
When a tank system has an inadequate
ratio of air and water, the pump will
start and stop often and erratically.
1. Disconnect electrical power to
pump.
2. open the lowest faucet in the
system to release all pressure.
3. Prime the pump.
4. Reconnect power.
as the pump refills the tank, the air
volume control supplies the tank with
the correct air to water ratio. the pump
will then shut off at desired pressure.
If tank water-logs again, examine air
volume control and replace if necessary.
