IMPORTANT: Well seal and piping must be protected
from freezing.
2. On a pitless adapter installation, the connection to the
system supply line is made below ground. Install the
pitless adapter following the instructions included with
particular brand or design being used in the installation.
NOTE: Follow ALL applicable state and local plumbing
codes.
PRELIMINARY TEST RUN
1. When pump is at desired depth, install throttle valve
for preliminary test run. Test cable for continuity with
an ohmmeter.
2. With pump discharge throttled, run pump until water is
clear of sand or any other impurities. Gradually open
discharge.
Be sure you do not stop pump before
water runs clear. This may take several hours. If pump
stops with sand in it, it will lock.
3. If pump lowers water in the well far enough to lose
prime lower pump in the well.
CONTROLLER LOCATION SELECTION
The CP WATER Subdrive standard NEMA 1 controller
is intended for indoor use and for operation in ambient
temperatures up to 125° F (50° C) at rated input voltage.
For outdoor installations, a system with a NEMA 4
rated controller must be used. (Models with 8th and
9th characters of “N4”). To ensure maximum weather
protection, the unit must be mounted vertically with the
cover properly aligned and secured with all lid screws.
The following recommendations will help in selection of
the proper location of the CP WATER Subdrive 100 unit:
1. A tank tee is recommended for mounting the tank,
pressure sensor, pressure gauge, and pressure relief
valve at one junction. If a tank tee is not used, the
pressure sensor should be located within 6 ft. (1.8
meters) of the pressure tank to minimize pressure
fluctuations. There should be no elbows between the
tank and pressure sensor.
2. The unit should be mounted on a sturdy structure such
as a wall or supporting post.
Unit Weight

Subdrive 75 15.0 lbs. 24.14 lbs.
Subdrive 100 17.5 lbs. 28.32 lbs.
Subdrive 150 17.5 lbs. 28.32 lbs.
3. The electronics inside the CP WATER Subdrive are
air-cooled. Allow room for air flow when installing.
There should be at least six inches of
clearance on each side and below the unit to allow room for
airflow.
4. The CP WATER Subdrive should only be mounted
with the wiring end oriented downward. The
controller should not be placed in direct sunlight or
other locations subject to extreme temperatures or
condensation).

*Wire with 90°C insulation only.
Due to the inherent voltage changing
characteristics of variable frequency drives (VFD), there
is additional stress placed on the insulation of the wire
between the controller and the motor compared to a
standard pump system. Extra care must be taken when
using Unjacketed Flat Parallel Pump Cable to ensure that
the insulation on each of the separated wires is the same
thickness. Care must also be taken to ensure a proper
seal with shrink tubing on any splices. Failure to take
these precautions can lead to “wire burn through” that
will shut down the system. Under these circumstances,
no permanent damage usually occurs to the controller or
motor. For further details call Technical Support at
1-800-742-5044.
