If the basement has water
or moisture on the floor, do
not walk on wet area until all
power is turned off. If the shutoff box
is in the basement, call an electrician.
Remove pump and either repair or
replace. Failure to follow this warning
could result in fatal electrical shock.
A check
valve
must be used on the primary sump
pump discharge.
This
pump
must only be used to pump clear water.
This pump is not designed to handle
effluent, salt water, brine, laundry
discharge or any other application
which may contain caustic chemicals
and/or foreign materials. Pump damage
may occur if used in these applications
and will void warranty.
Installation
Installation of this unit may take
several hours. Before disabling your
main pump, have ready an appropriate
means of evacuating the sump.
1. Turn power to main pump off.
2. Pump must be installed using 1¼”
or 1½” rigid PVC pipe. Do not use
flexible drain hose.
Pump Installation
The EWP10 can be installed with a
separate dedicated discharge line
(Figure 1, Method 1) or tied into the
existing sump pump line (Figure 2,
Method 2).
Unplug
the
existing AC pump. Failure to follow this
warning could result in fatal electrical
shock.
3. Verify that the existing AC pump
is in good working order. If the
AC pump is questionable, it is
recommended that the unit be
replaced.
4. Remove any silt or accumulated
debris from the sump pit and
surrounding area.
5. Locate the EWP10 in an ideal
position in the sump pit. The
ideal position is approximately
2” from the bottom of the sump
pit and located so that it does
not interfere with any part of the
existing sump pump.
6.
Method 1 Installation:
(Figure 1) Cut and dry-fit rigid
PVC pipe to the discharge of the
water powered back-up pump.
Cement all fittings and discharge
pipe after all pipe has been cut
and dry-fit together.
The
discharge
line installation will vary depending on
individual circumstances. Using sound
plumbing practices, route the discharge
pipe to an exterior wall by the shortest
path. Keep turns to a minimum because
they reduce the flow output of the pump.
The pipe that exits the building structure
should be sealed and sloped downward
so the water will not freeze in the pipe.
Method 2 Installation:
(Figure 2) Cut the existing main
pump discharge line and cement
a “T” or “Y” fitting. Measure,
cut and dry-fit the pipe required
to connect the EWP10 to the
installed “T” or “Y” fitting.
Cement all fittings and pipe.
7. Shut off the municipal water
supply. Install a rigid water
supply line to the sump area.
Include a shut-off valve in the
supply line. Flush the supply line
of all debris before installing the
automatic valve.
8. Connect the automatic valve
assembly with brass vacuum
breaker to the supply line. Is
should be located about 6” above
the basement floor or sump pit
cover. The supply line needs to be
supported.
9. Attach the hose coupling and
washer to the brass vacuum
breaker of the automatic valve
assembly.
10. Attach the “L” bracket to the
automatic control valve using the
two screws supplied.
11. Install the float rod by threading
the two parts together. Using
the large coupler, secure the rod
connection by threading the top
screw to the top part and the
bottom screw to the bottom part.
12. Install a small coupler and the
float to the float rod by inserting
the float rod through the center
of the float. Insert a small coupler
about ½” above the bottom of
the float rod and tighten the
fastener. Tighten the first small
coupler installed.
