PRE-INSTALLATION

GENERAL INFORMATION
The Battery Backup Combo Kit is pre-plumbed up to the hose and clamp assembly. The system includes the primary sump pump (PSP), backup sump pump (BSP) assembly, and vertical float switch. The unit is equipped with two check valves – one for the primary pump and one for the backup pump.
The battery backup pump is not a substitute for your primary sump pump. It is designed to temporarily backup your primary sump pump during a power outage or other problem which prevents normal operation of the primary pump. Do not use this system to pump flammable liquids or chemicals. Pump clear sump water only with this pump. For residential use only.
Keep the battery charger dry and protected from damage. This system is designed to work with either a sealed leadacid AGM battery or a flooded lead- acid battery. Use of a true Gel Cell (often confused for AGM) or a standard automotive battery with this charger is not recommended. An automotive battery may require charging after only 1-2 hours of continuous use, and the repeated charging cycles may cause early plate failure in the battery.

SPECIFICATIONS

NOTICE: Do not reduce size of discharge pipe or hose below 1-1/2” diameter. If discharge is too small, pump will overheat and fail prematurely.
NOTICE: If a Carbon Monoxide (CO) sensor is installed, it must be at least 15 feet away from battery charger in order to avoid nuisance CO alarms. Please refer to your CO detector’s installation guidelines for more information.

APPLICATION

• This compact primary and backup pump system is designed for home sump applications. Use this pump only for pumping water.
• This unit is not designed as a waterfall or fountain pump, or for applications involving salt water or brine! Use with waterfalls, fountains, salt water or brine will void warranty.
• Do not use where water recirculates.
• Not designed for use as a swimming pool drainer.

NOTE: Do not reduce size of discharge pipe or hose below 1-1/2 in. diameter. If discharge is too small, pump will overheat and fail prematurely. This pump is designed for use in a residential sump only. Only pump water with this pump.

INSTALLATION

1. Drain the sump pit as far as possible without running the pump dry. Do this by:
   A. Piggyback switch: Unplug the pump and switch from the outlet, then unplug the pump from the piggyback switch. Reset the circuit breaker or reinstall the fuse and plug the pump directly into the outlet. The pump will start.
   Drain the pit and unplug the pump. OR
   B. No piggyback switch: Reset the circuit breaker or reinstall the fuse and use a non-conducting broom handle or stick to raise the float switch; the pump should start. Drain the pit and then release the switch. When the pit has drained, turn off (open) the circuit breaker or remove the fuse again to avoid electrical shock while working on the installation. Unplug existing sump pump and place power cord and piggyback switch out of the way of work and water.

2. Measure the height from sump bottom to sewage pipe joint, make sure to leave enough discharge pipe.

3. Use hacksaw to cut the drain pipe to the length meeting the installation requirement.
   NOTICE: Depending on where your current check valve is located, there may be excess water. Let the water drain/drip into the sump pit.

4. Remove old sump from sump pit.
   NOTICE: Remove all sand, clay, and gravel before installing.

5. Install the 1-1/2 in. PVC rigid pipe on the quick connector.
   NOTICE: The quick connector must be tightened.

6. Place Combo pump into sump pit. Make sure vertical float switches can operate freely inside sump pit, once the Combo pump is firmly seated in the base of the pit, then connect the pump discharge pipe to the sewer pipe with flexible coupling.

7. Place the battery (sold separately) into the control box. Wiring the leads from controller: Red+ to battery Red+; Black- to battery Black-. Note: Be sure the battery box ventilation holes are unobstructed. Battery control box must be set up in a well-ventilated area. Smoking and open flames are prohibited.
   NOTICE: If the leads are reversed, the pump will run backward and not pump water.

8. Battery and control box wiring and set-up

1. Plug the backup pump male connector into the female connector “PUMP” on the control box
   2). Plug the float switch male connector into the female connector “FLOAT” on the control box.
   3). Plug the 12 V adaptor outlet plug into the power connector “POWER” on the control box.

   4). Follow the on-screen instructions. Test the pump operation by lifting and holding the float.
   The “Pump Status” LED will continuously light and the buzzer will beep steadily. The pump should start. If the pump does not run, check all the connections and reconnect them as necessary.

9. Battery backup system testingSecure power cord around pipe with a cable tie. Plug the primary pump into a standard household 15 amp outlet.
   NOTICE: The circuit should be dedicated to the sump pump exclusively.
   Remember: Do not handle the pump while it is plugged in; whether it is running or not.
   To verify the system is operational, press “RESET” button 1–4 seconds. The system will complete a self-testing diagnostic. The DC pump will run for 3 seconds.
   Green light is on: The system is normal.
   Yellow light quickly flashes and alarm sounds: Battery disconnected or DC fuse blown. Connect the battery or replace the fuse.
   Yellow light slowly flashes and alarm sounds: Power off or power adaptor failed.
   Yellow light is on: Battery recharging.
   Red light is on and the alarm sounds: Battery backup pump working.
   Red light slowly flashes and alarm sounds: Pump wire connection problems or pump failed.
   NOTE: Do not reduce size of discharge pipe or hose below 1 1/4” (3.2 cm) diameter. If discharge is too small, pump will overheat and fail prematurely. This pump is designed for use as a residential sump only. Only pump water with this pump.

10. Once all wiring is complete, fill your pit with water and verify that the primary pump removes the water and the backup pump doesn’t run. Then, unplug your primary pump and refill your pit with water. Verify that the backup pump removes the water.

OPERATION

WARNING: Risk of electric shock. Can shock, burn or kill. Do not handle a pump or pump motor with wet hands or when standing on wet or damp surface, or in water.

1. Shaft seal depends on water for lubrication. Do not operate pump unless it is submerged in water as seal may be damaged if allowed to run dry.
2. Motor is equipped with automatic reset thermal protector. If temperature in motor should rise, switch will cut off all power before damage can be done to motor. When motor has cooled, switch will reset automatically and restart motor. If protector trips repeatedly, pump should be removed and checked. Low voltage, long extension cords, clogged impeller, very low head or lift, or a plugged or frozen discharge pipe, etc., could cause cycling.
3. Pump will not remove all water. If operating a pump manually and suddenly no water comes out of the discharge hose, shut off the unit immediately. The unit has broken prime due to a very low water level.
   WARNING: Risk of electric shock. Can shock, burn or kill. Before attempting to check why unit has stopped operating, disconnect power from unit.
