8. Replace the cover. Do not over-tighten the screw.
9. Connect the other end of the pressure sensor cable
with the two spade terminals to the pressure sensor.
The connections are interchangeable.

A 10 foot section of cable is provided with the CP
WATER SD100 to connect to the pressure sensor.
Lengths of up to 100 feet can be used, provided the
appropriate shielded cabling is used. Consult the
factory for proper cable specification.
10. Set the pressure tank pre-charge to 70% of the
desired water pressure setting. To check the tank’s
pre-charge, de-pressurize the water system by
opening a tap. Measure the tank pre-charge with a
pressure gauge at its inflation valve and make the
necessary adjustments.
11. The pressure sensor communicates the system
pressure to the CP WATER SD100 controller. The
sensor is preset at the factory to 50 psi, but can
be adjusted by the installer using the following
procedure:
a. Remove the rubber end-cap.
b. Using a 7/32” Allen wrench (provided), turn the
adjusting screw clockwise to increase pressure
and counter-clockwise to decrease pressure. The
adjustment range is between 25 and 80 psi (1/4
turn = approximately 3 psi).
c. Replace the rubber end cap.
d. Reset the pressure tank pre-charge to the
appropriate pressure
12. Cover the pressure sensor terminals with the rubber
boot provided.
Start-Up Operation
Apply power to the controller. A steady green light
indicates that the CP WATER SUBDRIVE 100 has power
but the pump is not running. The green light will flash
continuously when the pump is running.
NOTE: Conventional private water systems intermittently
fill a pressure tank as commanded by a standard pressure
switch (e.g. 30 - 50 psi). The CP WATER SD100 maintains
a constant pressure at the pressure sensor up to the
maximum capability of the motor and pump. Although
the pressure is constant at the pressure sensor, pressure
drops may be noticeable in other areas of the home when
additional taps are opened. This is due to limitations in the
plumbing and will be more pronounced the further the taps
are from the pressure sensor. This would be true of any
system, and if observed, should not be interpreted as a
failure in the performance of the CP WATER SD100.
