Never run the pump unless it is completely 

submerged in water. If run without water, the pump and 

motor could be damaged. Note also that air drawn into the 

pump can cause an airlock under certain conditions.

provide protection against only induced voltage surges on 

secondary power lines; they are not effective against direct 

hits.

6. Mount the control box in an area protected from rain, snow, 

direct sunlight, or other high temperatures as this may cause 

tripping of the overload protector. Also protect the control 

box from extreme cold (below 25

o

F/-32

o

C) as this may have 

adverse effects on the starting capacitor.

7. A two-wire pump does not require a motor control box; all 

electrical components are built inside the motor. Figure 2 

shows a typical wiring diagram for a two-wire installation.

8. Use an ohm meter to make continuity and insulation checks 

after the installation is completed.

9. Place the additional pump nameplate onto the submersible 

label and place both onto disconnect switch or circuit 

breaker box for future reference.

INSTALLATION IN LAKE OR STREAM

A submersible pump is usually isolated at the bottom of a well, 

where electrical leakage from its motor and cable presents no 

hazard to life. This natural protection is lost when it is installed 

it in a lake, pond, stream, or fountain because there is no way 

to stop people and animals from entering or touching the 

surrounding water. It is recommended that such an installation 

be done by a licensed electrician in conformance with all 

applicable national and local electrical codes. Grounding as 

described in this manual is a minimum requirement, and a 

ground fault circuit interrupter (GFCI) is advisable. But in the 

absence of explicit national or local regulations, ask the local 

electric utility for guidance. In any case, support the pump 

from the shore or bottom at a 15

o

 slant to assure proper motor 

bearing lubrication. Shield the pump from direct physical 

contact by people and animals. Protect and screen the pump 

intake to prevent blockage by leaves and weeds, but remember 

the need for adequate 

fl

 ow over the motor for cooling purposes. 

In addition, protect the entire underwater installation from water 

currents, ice, boats, anchors, debris, vandalism, and other 

hazards.
