The foot valve strainer can be installed onto the bottom of
a 34’ long tail pipe, rather than the bottom of the packer,
to prevent over pumping of a low yield well. Soak the
packer assembly in warm water for 1 hour to make the
leathers soft and pliable. Lower or push the packer
assembly into the well on 1¼” suction piping. It should be
set at least 3’ below the lowest dynamic water level if you
are not using a tail pipe below the packer.The foot valve
strainer should be no closer than 3’ from the bottom of
the well.
WELL ADAPTER INSTALLATION
Packer systems require a well adapter (ordered
separately) at the top of the well. The well adapter
makes the transition from the vertical suction pipe and
well casing, to the horizontal suction and drive water
connections. The 1¼” suction pipe from the well must be
terminated with a 1¼” male NPT connection. Attach the
well adapter to this 1¼” male NPT fitting. Make sure the
OD of the well casing is smooth and clean. With the
gland bolts loosened, the rubber seal ring should slide
over the 2” well casing. With the well adapter in place,
tighten the 3 gland bolts uniformly to compress the seal
ring to the well casing OD. The Convertible VersaJet
pump can be attached directly to the well adapter using
the two 3/8”-16 x 1” bolts with flat washers supplied with
the well adapter kit, and the rubber gasket provided with
the suction flange kit. The pump may be separated from
the well adapter with horizontal offset suction and drive
water piping.
(see “HORIZONTAL OFFSET PIPING” above).
Priming will be easier if you fill the pipes with water
before attaching the pump. Make sure that all piping
slopes upward towards the pump and that no point is
above the pump suction. Connect the suction and drive
water pipes to the threaded connections on the pump
suction flange. Always double clamp barbed connectors.
Go to “DEEP WELL DISCHARGE PIPING” below
DEEP WELL DISCHARGE PIPING (FIGURE 5)
All deep well jet pumps require back pressure to properly
operate the jet assembly. To insure that you have the
required back pressure or drive water pressure, you must
provide a pressure control valve in the discharge line as
close to the pump as possible. Failure to install and adjust
a pressure control valve will result in loss of prime during
peak usage situations. Franklin Electric recommends the
use of a 1” control valve (Franklin Electric control valve
P/N 91980359) installed directly in the pump discharge
that has an alternate ¼” NPT pressure switch connection.
This alternate pressure switch connection allows the
switch to read the pressure on the outbound side of the
valve, rather than inside the pump case. Install the control
valve in the pump discharge. Remove the plastic tubing
from the quick connect fittings supplied on the pump.
Remove the quick connect fitting from the pump case and
move it to the ¼” NPT connection on the control valve.
Plug the ¼” NPT pump case hole with the plug provided
in the control valve kit. Install the new plastic hose
between the pressure switch and the control valve (cut it
to the proper length if necessary). Make sure you push
the plastic hose completely into the quick connect fittings
to insure a good water seal. See “ADJUSTING THE
CONTROL VALVE” below for adjustment procedures of
this valve.
The arrangement shown in
FIGURE 5 is typical and
suitable for any pipe material, but all components shown
are not required for proper use. The gate valves save
draining the entire system when servicing the pump or
pressure tank. There should be unions or other breakable
pipe connections close to the pump to allow for easy
accessibility when servicing. If the side discharge ports
in the pump case are used for discharge plumbing then
the top discharge port can be used for priming. If the top
port is used for discharge plumbing, priming can be done
through the top of the control valve installed in this port.
PRIMING THE PUMP
SHALLOW WELL PUMPS
Priming the pump means filling the pump and suction
piping with water. Priming is completed when you start
the pump, and all the air is removed from the piping
system, but before you energize the pump you must
manually fill the pump and suction piping with water. If
you used one of the side discharge connections on the
pump, you can easily fill the pump and piping with water
through the 1” top port. If you used the top port for
discharge plumbing, you may need to provide a priming
tee for filling with water. Please also remove the ¼” pipe
plug on top of the shallow well injector for venting
purposes while filling. Once this ¼” vent hole produces
only water, it should be plugged, and continue filling the
pump with water until full. All horizontal offset piping
should slope up from the well to the pump to ensue that it
is filled with water. Plug the filling hole and open slightly
a faucet close to the pump. Do not open it too much,
which will allow too much water to escape when you
