SECTION 6: Pentek
6.3 Storage and Drain/Fill Instructions
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.
1. 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.
2. 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.
3. 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.
4. 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.

Figure 3: If flow past motor is less than .5 fps (0.15 mps),
install 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.
