To insure correct rotation of three phase units, brace 
pump shell securely and apply power momentarily 
by snapping line switch quickly on and off. If rotation 
is correct, reaction of the shell will be clockwise 
when viewed from pump discharge (that is, pump 
shaft will rotate counter clockwise). Interchange any 
two leads at magnetic starter to reverse rotation.

5. Run pump and motor unit for a few seconds to 

ensure that it is in working order.

SUITABILITY OF WELL

Install the pump only in a well that has been properly 
developed. Water from an undeveloped well often 
contains an excessive amount of sand, dirt, and 
abrasives which can damage the pump. Check that 
the well is large enough to allow the pump to be set 
at the required depth. Don’t set the pump below the 
casing perforations or well screen unless you make 
arrangements to ensure an adequate fl ow of water 
over the motor for cooling purposes. Determine the 
correct pump setting from the driller’s record by taking 
into account the static water level and the drawdown 
at the proposed pumping rate. Keep the pump at least 
fi ve feet from the bottom of a drilled well.

SPLICING THE POWER CABLE

Follow the instructions enclosed in the cable splicing 
kit you purchase.

DROP PIPE

Galvanized pipe is recommended for suspending 
submersible pumps into the well. Plastic pipe may 
be used only when observing the plastic pipe 
manufacturer’s recommendations of depth and pressure. 
Give special consideration to:

1. A safety cable to prevent loss of pump if pipe should 

break.

2. Torque arrestor just above pump to prevent chafi ng 

the cable when pump and pipe twist during the starting 
and stopping cycle. (See Figure 1)

Schedule 40 galvanized pipe is suitable for settings to 
600 feet(180m). For deeper settings, use schedule 40 
pipe for the bottom 600 feet(180m), and schedule 80 for 
the remainder.

Take great care to keep pipes clean and free from 
pebbles, scale and thread chips. Make sound, air-tight 
connections at all fi ttings. Pipe sealant is recommended.

CHECK VALVES

Many pumps have a built-in or externally supplied check 
valve. For a pump without one, install a check valve 
immediately above the pump. Install an additional check 
valve above the ground. If the pump is more than 100 
feet (30m) below the wellhead, install another check 
valve in the drop pipe 100 feet (30m) above it. For pump 
settings deeper than 200 feet (60m), install additional 
check valves at intervals of 100 feet (30m).

REMOVABLE POPPET CHECK VALVE

4” submersible pumps with a 1-1/4” discharge are 
supplied with a spring-loaded REMOVABLE poppet style 
check valve assembly. The check valve can be removed 
from the pump discharge when the pump is installed in 
applications where drain back is desired.

 Fluid draining back through the pump 

can cause the pump to rotate backwards. If pump/
motor starts during this time; damage to the pump 
can occur.

The check valve can be removed with the use of the 
T-Handle Poppet Wrench(part no. 23498207). Ordered 
separately. Or, with standard needle nose pliers. The 
poppet assembly is left hand threaded and is removed 
by turning CLOCKWISE.

If reinstalling a Popppet Check Valve assembly, the 
assembly should be tightened to 15 inch-pounds.
