Splicing Wire To Motor Leads
Before installing the motor in the well, the drop cable must
be connected to the motor wires. Refer to the wire size
chart at the beginning of these instructions when selecting
wire size for the drop cable.
The underwater connection where the drop cable connects
to the motor wires must be done using the supplied
waterproof heat shrink kit. To make the connection, first
1
strip the wires
⁄
" and place the heat shrink tubes over the
2
wires. Then, connect the wires using the crimps. Finish by
shrinking the tubes over the crimps heating from the center
outward. The sealant in the tube will flow out the ends
making a watertight seal. If a heat shrink tube is burnt or
split, the connection will need to be remade. Vinyl
electrical tape is not acceptable for underwater splices
when using variable speed drives due to the high potential
for leakage to ground through taped joints. Failure to use
supplied heat shrink kit will void the warranty.
Tank and Pressure Sensor
EXPLODING TANK CAN INJURE OR
WARNING
KILL.
Refer to pump catalog or contact your
supplier for maximum discharge pressure
of pump. Ensure pressure rating of pipe is
greater than maximum discharge pressure
of pump.
It is likely that the pressure relief valve will
CAUTION
open sometime during the life of the system.
Plan ahead by running drain to a location where water will
not cause damage.
Locate the tank and pressure sensor in an area where
temperatures stay above 32°F (0°C).
The relief valve, pressure sensor and pressure gauge must
ALWAYS sense tank pressure. No valves, filters, or flow
control devices can be between the pressure sensor and the
tank.
The pressure sensor will be connected to the controller. See
"Wiring Pressure Sensor" when determining allowable
distance between sensor and controller.
To prevent the pressure sensor from filling with sediment,
it must not be mounted upside down. Any orientation
between horizontal and vertical is acceptable.
The minimum tank size required for any BF15 system is a
Goulds Pumps Hydro-Pro V6P , or equivalent 2 gallon
diaphragm style pressure tank. For application with pumps
above 20 GPM, we recommend a Goulds Pumps Hydro-
Pro V15P , or equivalent 5 gallon diaphragm style pressure
tank for best system performance.
The diaphragm style pressure tank used with this BF15
system MUST BE RECHARGED to 10 PSI below the
desired system set pressure. Please refer to the charging
instructions for your selected diaphragm style pressure
tank.
Controller
The controller is rated NEMA 3R (Raintight), so it may be
located outdoors if needed. It must be mounted vertically.
Locate the enclosure in an area where the temperature
stays within -30°F to +130°F (-34°C to +55°C).

Opening Controller Cover
Pins in slots at the top and a screw at the bottom hold on
the enclosure cover. To remove the cover, remove the
screw and unhook the pins at the top by sliding the cover
up and out.
Mounting Controller
Three screws are provided for mounting the enclosure
(Figure 1).
Figure 1: Mounting Holes
Using the enclosure as a guide, select a mounting location.
First install the top screw in the mounting surface leaving
the head of the screw approximately
Hang the enclosure on this screw. Finish by installing the
two bottom screws and tightening the top screw. Open the
flap cut into the protective cardboard cover to access the
top mounting screw (Figure 2). Close the flap when
finished.
Wiring Pressure Sensor
The pressure sensor cable is pre-wired at the factory. If
desired, the length of the cable can be changed. The cable
can also be put in conduit to protect against damage.
To change the length of the cable, loosen the terminal
screws where the cable attaches to the circuit board and
remove the wires. Lengthen or shorten the cable as
necessary by cutting or splicing. The cable length cannot
exceed 200 ft. Long cables may be affected by interference.
If pressure sensor cable is long, pressure control may
become erratic.
To put the sensor cable in conduit, do the following.
Disconnect the cable from the terminal block on circuit
board and remove the cable strain relief in the bottom of
the enclosure. Starting at the enclosure, run flexible or rigid
1
⁄
" conduit to where the sensor is located. The last few feet
2
of conduit adjacent to the sensor will need to be flexible.
The conduit must be well supported – NO stress can be
placed on the pressure sensor connector. Use a strain relief
bushing to seal around the pressure sensor connector.
After reconnecting the sensor wires to the

terminal block, tug on each wire individually
to ensure they are tight.
