Operating Instructions and Parts Manual
APPLICATION AND OPERATION
6. Plug the pump into a 120 volt GFCI protected outlet. The
pump will start pumping automatically when the water reaches
a depth of 1-3/4 inches. A priming delay of 2 seconds is
programmed into the control to allow time for air to escape
from the pumping chamber.
7. The pump will stop automatically once water has been
removed to a depth of approximately 3/8 of an inch above the
hard surface. The pump will not restart until the water depth
rises to 1-3/4 inches or greater.
8. The pump will not allow itself to run dry. Once the pump
detects that water is no longer being removed, it will shut down
automatically. The pump must remain upright at all times in order
for the water detection to function. Do not allow the pump to
operate on its side or inverted.
Do NOT alter the pump to override the
automatic water detector. The shaft seal depends on water for
lubrication. Overriding this pump feature can cause the pump to run
dry and may damage the shaft seal and cause pump failure and void
warranty.

MAINTENANCE

Pump starts automatically. Always disconnect
electric supply before attempting to install, service, relocate, or perform
any maintenance. Failure to do so could result in fatal
electrical shock.
La pompe démarre
automatiquement. Toujours couper le courant avant
d'essayer d'installer, de réparer, de déplacer ou d'effectuer toute
opération de maintenance. Le non-respect de ces instructions pourrait
entraîner un choc électrique mortel.
1. Periodic cleaning of pump is required to maintain performance
of the pump. Follow the cleaning steps listed below:
a. Unplug the power cord.
b. Remove the four (4) base screws (Figure 2).
c. Remove the base and impeller plate.
d. Remove the debris and make sure the impeller turns freely.
e. Reinstall impeller plate, base, and screws.
f. Use a pin or paperclip to clean the priming hole and air
escape channel.
PUMPING HEIGHT
When water is pumped to an elevated position, any volume that has not
reached the discharge outlet can flow back through the pump when
the pump shuts off. This back-flow can cause the water level in small
areas to rise enough to re-start the pump. A check valve [Check Valve Sold
Separately] is required in this situation. For proper operation, make certain
the check valve is oriented as instructed.
In small areas a check valve is required
to prevent backflow. Without a check valve the pump may cycle
continuously and potentially wear out the pump components.
