Note: Again for very narrow sump pits, pumps can be
stacked on top of each other. Pump 1 must be the lowest
pump.
Note: Make sure the RED filter screen is securely
attached to each pump.
Remove each pump and insert each vertical PVC piece into
the Elbow, tighten hose clamps securely. Place each pump
into pit again and insert PVC into the corresponding check
valve. Tighten hose clamps securely.

MPORTANT: REVIEW ALL SAFETY PRECAUTIONS AND
INSTRUCTIONS BEFORE PROCEEDING!
Finishing Installation
:
Step 1: POSITIONING THE SENSORS:
Sensor 1 is the main sensor and will turn on the pump(s) when
the water rises above the sensor. The Gray Sensor should be
used for Sensor 1. Sensor 2 does not operate exactly like
Sensor 1 however, functions as a backup and high water
alarm. (See Sensor Operations). The Black Sensor should be
used for Sensor 2. Attach the sensors to any discharge pipe
securely with the supplied stainless steel clamps (float side
down,sensor cable up, mounting bracket up, remove any ship-
ping tape). Float on each sensor should move freely up and
down.
Position the sensors as described below.
Sensor1 (Bottom Sensor Receptacle):
NexPump in Backup Mode:
Position Sensor 1 approximately 4 - 6 inches above the activation
level of the Main pump. If not, the NexPump may show the
pumps have been activated prematurely.
NexPump in Primary Mode (Only Sump Pump):
Position Sensor 1 approximately 2 - 4 inches above the pumps.
NexPump in Primary Mode (With Electric Sump Pump):
Position Sensor 1 above the level of the NexPump pumps
and below the level that the AC pump will turn on.
Sensor 2 (Top Sensor Receptacle):
Sensor 2 is used as a backup and alert for high water. When activat-
ed the NexPump will begin operation in a special emergency mode
and with ‘Auto Notification’ will alert immediately. Position sensor 2
about 6 inches above all other trigger points.
IMPORTANT : If a vent hole is drilled in the discharge pipe
make sure a sensor or sensor clamp does not block the vent
hole. Do not position the sensor on the side of the discharge
pipe facing the drain tile or any incoming rush of water.
Be sure the sensor is positioned vertically with the mount-
ing bracket at the top.Verify the sensor is not tilted in any
way.
Step 2: SECURE WIRES:
Secure the pump and sensor wires to discharge pipes with
nylon wire ties.
IMPORTANT : Make sure the wire ties or wires do not
interfere with the operation of the sensor.
Step 3: POSITION BATTERY AND NEXPUMP
SYSTEM UNIT:
Place the battery in a battery box (if used) on the floor or on
a secure shelf or ledge. Position the NexPump System Unit
in a secure place ideally above the floor. Two 8” shelf brack-
ets attached to the basement wall work fine to support the
NexPump. The pump wires and sensor wires should be long
enough to position the NexPump System Unit approximately
1-2 feet above the floor. Be sure the power cord will reach
the AC power socket. Secure the electrical power cord as
needed. Do not plug in at this time. Make sure battery
cables will reach battery. Do not connect battery cables at
this time.
Step 4: PUMP AND SENSOR CONNECTIONS:
Plug the pump connectors into the NexPump System Unit.
If both pumps are not on the bottom of the pit then
Pump 1 must be the lowest pump. Slightly pull back on
each connector to verify they are securely attached. Plug in
the Sensors. Primary Sensor (Sensor 1) to bottom recepta-
cle. Backup Sensor (Sensor 2) to top receptacle. The sensor
connectors plug in with the security latch to the right of the
NexPump System Unit. Verify the sensor connectors are
securely attached.
IMPORTANT:
To disconnect a pump connector, slightly depress the
security latch on the bottom of the connector and pull
out the connector.
To disconnect a sensor connector, slightly depress the
security latch on the right side of the connector and pull
out the connector.
Step 5: CONNECTING THE AC POWER CORD:
IMPORTANT: Make sure that the AC outlet is a grounded
outlet.
If you have an electric pump you still want to operate, you
should install a duplex receptacle (if you have a single outlet
receptacle). This will allow an outlet for the NexPump Unit
and your electric pump. A 20 amp receptacle should be used.
Note: Turn off the power to the outlet if replacing the
receptacle is necessary.
Plug in the AC power cord and verify a secure connection.
The NexPump Unit will turn on. The display will illuminate
and ‘Operating Status’ LED should be blinking. The NexPump
will display ‘NexPump, Inc.” and then the normal status mode.
