AC POWER REQUIREMENTS
The NexPump System Unit must be operated from 120 volt
household current from the AC outlet.
GROUNDING AND AC CORD INSTRUCTIONS
The NexPump System Unit should be plugged into
an outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
DANGER
Never alter the AC cord or plug provided – if it will not fit the
outlet, have a proper outlet installed by a qualified electrician.
Improper connection can result in a risk of an electric shock.
An adapter should not be used with this
NexPump System Unit.
Important Safe Guards:
Never allow other items that discharge into the sump pit
to be unsecured. Unsecured items such as garden
hoses, laundry hoses and other medium used to dis-
charge water may interfere with the NexPump pumps or
sensors. Be sure to secure all items that may be used to
discharge water into the sump pit and verify that
secured items will not interfere will any NexPump opera-
tions.

NSTALLATION PROCEDURES:
Installation of plumbing has many options depending on how
the plumbing is setup in the first place. The most common
method whether the NexPump is used as the
primary(Diagram A) or a backup(Diagram B) is to wye the
existing plumbing. If this is a new installation just one wye
will be needed to create two discharge paths for each pump.
Each pump can also have a separate discharge if this is
preferable. However in most cases the use of tees or wyes will
work fine. 2” PVC can be used to get the full dual pump dis-
charge rate. The 2” only needs to be installed from the wye
to the outside. Check valves must be installed when a com-
mon discharge is used. The check valves are designed to go
one way, verify the correct direction when installing the check
valve.
Note: If you are installing a single pump version, install using
Diagram A as a reference. The second pump would be your
installed electric pump.
PARTS NEEDED FOR INSTALLATION:
Check Valves,PVC pipe, PVC cement and primer,Nylon Wire
Ties
Install plumbing referring to the examples diagrams at that
end of this users manual. The diagrams and the following
assume 1-1/2" PVC pipe will be used. Arrange plumbing so
when the vertical pieces are connected, the pumps will fit into
the sump pit and each pump will sit on the bottom of the pit.
Note: For very narrow sump pits, pumps can be stacked
on top of each other. Pump 1 must be the lowest pump.
Connect the wye to the discharge pipe. Connect the 45
degree elbow(s) to the wye. To attach check valves cement
small pieces (approximately 2-1/2") of PCV pipe. This will
allow enough PVC for the check valves to attach securely.
Attach the check valves and securely tighten the hose
clamps to the upper part of the PVC.
Note: Tighten all the hose clamps on check valves, not
just the ones you are fitting.
Attach the Elbows to each Pump and tighten pump side
clamp securely. Place and position each pump into sump pit.
Measure from the Elbow of each pump to corresponding
check valve, add approximately 2-1/2” for insertion into check
valve and elbow. Cut PVC to measured length. Drill a 1/8-
inch vent hole approximately 3” from the end that will be
inserted into the Elbow. Do this for each piece of PVC piece.
IMPORTANT: When using a check valve a small 1/8” hole
must be drilled in the vertical discharge pipe of each
pump. DO NOT DRILL INTO THE PUMP OR THE ELBOW.
The hole should be drilled at a 45 degree downward
angle to prevent water spraying upwards and position
the hole about 2” above the Top of the Elbow.
Trim as necessary so each pump will sit on the bottom of the pit
as close to level as it can be.
