13. The float should be set so that
the primary pump starts before
the EWP10. Insert the float rod
through the “L” bracket hole.
Install a rubber grommet onto the
float rod, then insert the float rod
through the automatic control
valve arm and then install the
second rubber grommet on the
top of the float rod.
14. If necessary, adjust the length of
the connecting hose and attach
to the EWP10 pump with the
supplied hose clamp.
15. Turn on the water supply and
check the installation for joint
leaks and proper operation.
Simulate water activating the
water powered backup system
by raising the float to trip the
automatic control valve arm.
Hold the float in the up position
while checking the system for
leaks. Lower the float to turn off
the system and fix any leaks in
the water supply line. Retest if
necessary.
16. Fill the pit with water until the
float trips the automatic control
valve arm. The system will lower
the water level in the pit to the
shut off point of the EWP10.
Verify this on/off level of the
EWP10 is higher than the on level
of the main sump pump.
17. Reconnect power to the main
sump pump. The water level in
the pit should lower to the off
point of the main sump pump.
Test the system again to verify
that the main sump pump and
the EWP10 work together.
Operation
Always disconnect the power
source before attempting to
install, service, relocate or
maintain the pump. Never touch sump
pump, pump motor, water or discharge
piping when pump is connected to
electrical power. Never handle a pump
or pump motor with wet hands or when
standing on wet or damp surface or in
water. Fatal electrical shock could occur.
Risk of electrical shock! Use a
GFCI receptacle to reduce the
risk of fatal electrical shock.
Cutting the cord or plug will void
the warranty and make the pump
inoperable.
