ELECTRICAL
Hazardous Voltage. Can cause severe or
fatal electric shock. Pump is supplied with a grounding con-
ductor and grounding-type attachment plug. To reduce risk of
electric shock, be certain that it is connected only to a prop-
erly grounded, grounding type receptacle. Ground terminal
on pump cord plug is provided for your protection. DO NOT
REMOVE!
OPERATION / MAINTENANCE
Risk of electric shock. Before attempting to
check why unit has stopped operating, disconnect power
from unit. Do not handle pump with wet hands or when
standing on wet or damp surfaces, or in water.
Risk of flooding. If a flexible discharge hose
is used, pump may move when motor starts. If the switch hits
the side of the sump, the switch may stick and prevent the
pump from starting. Make sure the pump is secured so it
cannot move around in sump.
Risk of sudden starts. The pump motor is
equipped with automatic resetting thermal protector and
may restart unexpectedly.
1. If protector trips, motor may be overloading. Check for
the following problems:
A. Not enough back pressure in discharge pipe.
B. Voltage too high or too low.
C. Wires to motor too small.
D. Motor incorrectly connected to power supply wires.
E. Defective motor.
2. Shaft seal depends on water for lubrication and cooling.
Do not operate pump unless it is submerged in water as
seal may be damaged if allowed to run dry.
3. Motor is equipped with automatic reset thermal protector.
If temperature in motor should rise unduly, switch will cut
off all power before damage can be done to motor. When
motor has cooled sufficiently, switch will reset automati-
cally and restart motor. If protector trips repeatedly,
unplug the pump and remove it; check for cause of diffi-
culty. Low voltage, clogged impeller, very low head or lift,
etc., could cause cycling.
4. Pump will not remove all water. If manually operated
pump is operating and suddenly no water comes out dis-
charge hose, shut off unit immediately. Water level is
probably very low and unit has broken prime.
