Safety
MOTOR STORAGE AND INSTALLATION
1. The motor is filled at the factory with anti-freeze which
will protect it in temperatures down to –22ºF (-30ºC).
Do not install, transport or store the motor below these
temperatures if the motor is filled. If storage is necessary
at temperatures below –22ºF (-30ºC), drain the anti-
freeze from the motor.
2. Verify that the motor is full before installing. If not,
fill it with clean water (see below). Installing a motor
that is not filled with liquid will void the warranty.
Before installation, check all water fill and drain plugs,
mounting bolts, and cable connections for tightness.
Refill the motor with clean water as follows:
A. Stand the motor on end (vertically) and remove the
fill plug with a 5mm hexagonal screw driver.
B. Turn the motor shaft by hand while rocking the motor
back and forth (see Figure 2).
C. Pour in clean water until the motor is as full as
possible.
D. Repeat the turning/rocking procedure.
E. Check the liquid level. If necessary, add more clean
water.
F. When the motor is full, re-install the fill plug. Tighten
it with the 5mm hexagonal screw driver.
Support motor while rocking to prevent motor
from falling over.
A. Rock motor
while turning
shaft.
Figure 3: Rock Motor gently from side to side while turning
shaft by hand (A), then fill with clean water (B). Repeat until
full.
B. Fill motor;
repeat rocking
and filling until
motor is full.
NOTICE To avoid damaging the motor thrust bearing, do not
hammer on the shaft, coupling, or slinger. Check the motor
rotation by hand to make sure that it turns freely.
3. To avoid damage to the motor diaphragm, make sure that
the bottom of the motor does not touch the dirt or mud
at the bottom of the well. Install the motor at least 10'
above the well bottom.
4. To install the motor horizontally, lay it down with the
lead wires at 12 o'clock when you are facing the motor
shaft. To prevent any load on the shaft and bearings and
to avoid any damaging vibrations to the motor, mount
the motor solidly on the pump end and make sure that
the pump and motor are accurately aligned.
5. Install the motor so that during operation water flows
past all parts of it at a rate of at least 0.5 fps (0.15 mps).
If the well will not provide this flow, install a sleeve on
the motor to channel water past it (see Figure 3). Do not
try to operate the motor in mud or sand. To do so will
damage the motor and void the warranty.
6. Electrical connections: Connect the three motor leads
to the three hot motor leads (red/yellow/black or black,
brown, and blue) in the incoming cable. Connect the
ground wire (green or green and yellow) in accordance
with NEC or CEC requirements (as applicable) and
in accordance with all applicable local codes and
ordinances. Apply power momentarily to check rotation.
If the motor runs backwards, interchange any two power
leads to reverse direction of rotation.

or more
Figure 2: If flow past motor is less than .5 fps (0.15 mps), in-
stall a flow inducer sleeve as shown. Flow must be at least .5
fps (0.15 mps) for adequate motor cooling. The flow inducer
sleeve should not touch the side of the motor.
