MOTOR STORAGE AND INSTALLATION
1. The motor is filled at the factory with water / anti-freeze
mixture which will protect it in temperatures down to
–14ºF (-10ºC). Do not install, transport or store the motor
below these temperatures if the motor is filled. If storage
is necessary at temperatures below –14ºF (-10ºC), drain
the water / 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. Set the motor on its side (horizontally). Remove the
filling hole (1) and emptying hole (2) screws. Pour clean
water into the motor make sure there is no air left inside.
Replace the emtying hole (2) screw (see Figure 3).
B. Stand the motor up on its base (vertically). Fill the
motor the rest of the way through the filling hole (1).
Wait 2-3 minutes to make sure there is no air left in the
motor. Fill motor completely and close the filling hole
(see Figure 3).
NOTICE Running the motor without water can cause serious
injury and void warranty.
Support motor while rocking to prevent motor
from falling over.
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 shown in the Water Flow Rate
chart on Page 4. If the well will not provide this flow,
install a sleeve on the motor to channel water past it. 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 (black, brown, and blue) in
the incoming cable. Connect the ground wire (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.

the side of the motor.
