7. If water is trapped in the discharge pipe and freezes, it
could cause damage to the pump. If the discharge pipe
will be exposed to sub-freezing temperatures, install the
pipe so that it will drain completely when the pump stops.
8. After the piping has been installed, the unit is ready for
operation.
9. Check the pump by filling the sump with water and
observing the pump's operation through one complete
cycle.
Failure to make this operational check
may lead to flooding and premature pump failure.
NOTICE: This unit is not designed for applications involving salt
water or brine! Use with salt water or brine will void warranty.
ELECTRICAL
hazardous Voltage. Can cause severe or
fatal electric shock. Pump is supplied with a grounding
conductor and grounding-type attachment plug. To reduce
risk of electric shock, be certain that it is connected only to
a properly 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 automatically and restart motor. If protector trips
repeatedly, unplug the pump and remove it; check for
cause of difficulty. 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
discharge hose, shut off unit immediately. Water level is
probably very low and unit has broken prime.
