Never pull directly on any wiring connected to pumps, battery, AC power or sensors. Disconnect by pulling on connectors only.

Never force the connectors out of place, they should disconnect and connect easily. Some connectors have safety latches, so make sure they are depressed.

Never attempt any maintenance and/or cleaning with the NexPump powered up. Risk of electric shock may result.

WARNING - RISK OF EXPLOSIVE GASES WORKING IN THE VICINITY OF A LEAD-ACID BATTERY CAN BE

DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION.

FOR THIS REASON, IT IS OF THE UTMOST IMPORTANCE THAT EACH TIME BEFORE USING YOUR NEXPUMP

CONTROL UNIT YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY.

A SPARK NEAR THE BATTERY MAY CAUSE AN EXPLOSION.

Be sure the area around the battery is well ventilated.

Personal Precautions

If LEAD-ACID battery is used

Someone should be within range of your voice and/or close enough to come to your aid when you work near a lead-acid battery.

Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

Wear complete eye protection and clothing protection. Avoid touching your eyes while working near the battery.

If the battery acid contacts skin and/or clothing, wash immediately with soap and water. If acid enters the eye, immediately flood eye with running cold water for at least ten minutes and get medical attention immediately.

When the battery fluid level is low, add distilled water in each cell until the level reaches the indicator on each cell. Do not overfill.

Precautions for all Batteries

Page 4

NEVER smoke or allow a spark or flame in the vicinity of the battery.

Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or another electrical part that may cause an explosion.

Remove personal metal items such as rings, bracelets, necklaces and/or watches when working with a battery. A battery can produce a short circuit current high enough to weld a ring (or the like) to metal, causing a severe burn.

When cleaning the battery terminals be careful to keep corrosion from coming in contact with eyes.

Do not use the system unit for charging dry-cell batteries that are most commonly used with household appliances. These batteries may burst and cause injury to persons and damage to property.

NexPump Precautions

NexPump system unit location

Locate the NexPump system unit as far away from the battery as the DC cables permit.

Do not operate the NexPump system unit in an area with restricted ventilation.

Do not set a battery on top of the NexPump system unit.

Do not allow the NexPump system unit to sit on top of the battery.

Do not block the NexPump system unit ventilation in any way. Allow at least six inches of free space from the fan exhaust on the right side of the NexPump unit.

Do not install the NexPump system unit where temperatures will be below freezing (32 degrees Fahrenheit).

Do not install the NexPump system unit where it will be exposed to outside elements.

DC Connection Precautions

The NexPump unit requires a connected marine type deep-cycle battery for proper operation. You must assure the battery is connected while the NexPump unit is operating.

When attaching the battery cables to the battery posts, secure them to insure a good connection.

The BLACK wire from the NexPump system unit connects to the NEGATIVE (-) post of the battery. The RED wire from the NexPump system unit connects to the POSITIVE (+) post of the battery.

The ‘REVERSE POLARITY LED’ will illuminate if the battery connections are reversed.

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 the NexPump system

unit.

Important Safe Guards

Page 5

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 discharge 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 operations.

Installation Procedures

Installing the NexPump does require some plumbing expertise. You can use the installation diagrams at the end of this document as a reference for proper installation. For a Dual Pump NexPump System, separate discharges are recommended for maximum discharge rates and multiple output paths. If a Dual Pump NexPump System is installed as a backup, then you can use a WYE, however install one NexPump Pump on the straight through of the WYE and your normal electric pump on the 45 degree of the WYE. The remaining NexPump Pump should be installed as a separate discharge. You can install all the pumps in a multiple wye configuration, however this type of installation may reduce the total discharge capacity about fifteen (15%) percent at high discharge rates.

Points for Proper Installation

Tighten hose clamps on check valves if applicable.

Tighten pump adapters securely.

Install separate discharges for maximum discharge rate.

Make sure the RED filter screen is securely attached to each pump.

For very narrow sump pits, pumps can be stacked on top of each other. Pump 1 must be the lowest pump.

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.

IMPORTANT: Ai Turbo NexPump. Pump 1 must be the pump with the RED WIRE LOOM.

REVIEW ALL SAFETY PRECAUTIONS AND INSTRUCTIONS BEFORE PROCEEDING!

Finishing Installation

Step 1: Positioning the Sensors

Sensor 1 is the main sensor and will operate 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 white 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 shipping tape). Float on each sensor should move freely up and down.

Position the sensors as described below.

Sensor 1 (Left 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 (Right Sensor Receptacle) Sensor 2 is used as a backup and alert for high water. When activated the NexPump will begin operation in a special emergency mode and with the ‘Auto Notification’ feature will alert immediately. Position Sensor 2 about six inches above all other trigger

Page 6

points.

Be sure the sensor is positioned vertically with the mounting bracket at the top. Verify the sensor is not tilted in any way.

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.

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 System Unit

Place the battery in a battery box (if used) on the floor or on a secure shelf, rack or ledge. Position the NexPump system unit in a secure place ideally above the floor. The pump wires and sensor wires should be long enough to position the NexPump system unit approximately 3-4 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. Plug in the sensors. Primary sensor (Sensor 1) to left receptacle. Backup sensor (Sensor 2) to right 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: Ai Turbo NexPump. Pump 1 must be the pump with the RED WIRE LOOM.

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.

Plug in the NexPump's AC power cord and verify a secure connection. The display will illuminate and ‘Operating Status’ Green LED should be blinking.

Note: An alarm may sound at this time because the battery is not connected.

Step 6: Connect Battery

Attach the battery cables to the battery, the BLACK wire to the NEGATIVE (-) post, the RED wire to the POSITIVE (+) post and tighten securely.

IMPORTANT: Check the ‘Battery Reverse’ LED on the NexPump system unit and if it is illuminated the connections are

reversed.

Step 7: Check Your NexPump

All alarms should be off at this time. Set your preferred mode setting (see mode selection). The NexPump will schedule an automatic self-test approximately two minutes after power up. If there are any alerts they will be displayed on the LCD display and an alarm will sound.

Step 8: Secure Battery Boxes

If battery boxes are used, place each battery in the battery box.
