Safety Information
Read these warnings carefully. Know the application and limitations of this pump. Failure to follow these warnings could result in serious bodily injury and/or property damage.
DANGER  RISK OF ELECTRICAL SHOCK. Disconnect and lockout power supply before removing old pump or installing or servicing this pump.
DANGER This pump is designed to pump clear water. Do not use this pump to pump chemicals, flammable liquids, sewage, or corrosive liquids. You could injure yourself and the pump will fail. Pumping these types of liquids voids the warranty.
DANGER This system is designed for indoor use only. Keep all electrical connections away from wet and moist environments. Wet connections can cause electrical shock resulting in personal injury. Do not plug in or unplug the power supply cord(s) while standing on a wet floor or in water. If the floor is wet, disconnect power to the pump before walking on the floor.

WARNING   Battery acid is corrosive. Do not spill on skin, clothing, or parts of this system. Wear gloves and eye protection when handling the battery.

WARNING  DO NOT use the power cord to install or carry the pump. The cord may pull apart exposing bare wires which could cause a fire or electrical shock. Use the handle supplied with the pump for installing and transporting the pump.

WARNING Do not run the pump dry. This pump relies on water for cooling and lubrication. Running the pump dry can cause the pump to overheat and the possibility of burns to anyone that handles the pump. Running the pump dry will void the warranty.
WARNING This system is designed to be used in a residential backup sump pump application only. It is not designed to be used as a primary sump pump.
WARNING Make sure the sump basin is clear of rocks, sand, mud & debris. Debris can damage or clog the pump which could result in flooding.
WARNING The products can expose you to chemicals including vinyl chloride which is known to the state of California to cause cancer. For more information go to www.P65Warnings.ca.gov
CAUTION Do not use this pump for potable/drinking water. Use only in applications for which the pump is designed.

Battery Selection

This system is designed to work with 12 volt, lead-acid, deep cycle marine/RV, and AGM batteries. Either a flooded cell (serviceable or maintenance-free) or sealed AGM battery is acceptable It is recommended to choose a battery with a minimum 40 amp-hour rating. The higher the amp-hour rating on the battery, the longer the pump will run on battery power. Avoid using automobile batteries as these types of batteries are not intended to be charged/ discharged for extended periods of time.
The battery case will accommodate group 24 or 27 batteries.
During prolonged periods of power failure or in an emergency situation, your automobile battery may be used. Make sure to replace the deep cycle battery as soon as possible as the automobile battery will be quickly damaged by the continuous charge/discharge cycles.

General Information

This battery backup system is not intended to replace or be used without a primary sump pump. It is intended to provide temporary backup during power failures or malfunctions associated with the primary pump.
Carbon Monoxide (CO) Detectors
All backup pump systems that use lead-acid batteries, regardless of brand, give off gaseous by-products when the battery is charging. Some of these by- products can cause a carbon monoxide (CO) detector to give a false alarm. When installing this system, position the battery as far away from the CO detector as possible. DO NOT move or remove CO detectors from their original location. Always follow the instructions that accompany your CO detector.

If your CO detector alarm sounds, take the following actions.

1. Take immediate action for personal safety as outlined in the CO detector manual.
2. Contact the appropriate utility agency to determine if the CO is coming from your furnace, water heater, or other appliance that uses natural gas.

If it’s determined that a charging battery is causing the CO detector to activate, contact the battery manufacturer for recommendations on how to alleviate the problem.
Installation
WARNING Always disconnect the power source before attempting to install, service, or perform maintenance on the pump (primary or backup). Failure to do so may result in a fatal electric shock. If required, a qualified electrician must install all wiring.
WARNING This system is designed for indoor use only. Do not install outdoors or where the electronics could be exposed to wet conditions.

TOOLS & MATERIALS REQUIRED

• Pencil or marker
• Socket wrench with 10mm socket, 10mm nut driver, or adjustable wrench
• Hacksaw
• Pipe cleaner & cement
• Pliers
• Slip joint pliers
• Tape measure
• Deep cycle battery (see battery selection section)

NOTE: Install this system when the primary pump will not be required.

1. Start by finding the water level at which your primary pump turns on. Mark this point on the discharge pipe with a pencil or marker.

2. NOTE: If your existing discharge pipe is metal or flexible tubing it will need to be replaced with Schedule 40 PVC or ABS pipe.

3. Drain as much excess water from the sump basin as possible.

4. When the basin has been drained, turn off the power to the outlet/pump to avoid the risk of electrical shock.

5. Before removing the primary pump, make sure the discharge pipe is properly supported to prevent it from collapsing.

6. If your installation uses a flexible pipe coupling with hose clamps, simply disconnect the coupling and remove the pump. If a flexible coupling is not used, cut the pipe using a hacksaw as close to the floor level as possible and remove the pump from the basin. NOTE: BE PREPARED FOR WATER TO LEAK FROM THE PIPE WHEN CUTTING. Keep tools and components of this system away from the work area when cutting pipes. If any components get wet, make sure they are dry before installing.

7. . If your primary pump does not have a check valve in or near the pump discharge, install one at this time (sold separately). It is necessary to have a check valve installed on both the backup pump and on the primary pump. NOTE: The primary pump check valve must be located below the junction of where the backup and primary piping meet. This is to prevent backflow from the backup pump when it is running.

8. Attach the backup pump to the primary discharge pipe using two U-Bolts, Clamps, washers, and nuts (G). Position the backup pump so it is located near the water level that was marked in Step 1. Tighten the nuts using a 10mm socket or adjustable wrench. DO NOT overtighten. NOTE: Make sure the U-bolts are properly seated in the recessed channels on the pump mounting bracket. (The pump mounting bracket comes pre-attached to the pump).

9. Thread the check valve (C) onto the discharge of the backup pump

10. Plumb the backup pump to the primary pump piping using a 1-1/2″ Female Adapter (D), 45° Street Elbow (E), and a Wye fitting (F). It is highly recommended to do a “dry fit” before permanently gluing the pipe and fittings together. Place the assembly in the basin to make sure that it fits and that the primary float switch operates freely before permanently gluing the pipe and fittings together.

11. Remove the assembly from the basin and glue all fittings.

12. Secure the float switch to the discharge pipe using the provided mounting clamp and hose clamp. See figure 2 below for proper installation. DO NOT fully tighten the clamp at this time. Leave it a bit loose so you can adjust the position of the float in the next steps.

13. After the float switch has been attached to the discharge pipe, place the entire assembly in the basin. Make sure the primary pump float switch will operate freely and not contact the sides of the basin. Connect the pump assembly to the discharge pipe. Use either a flexible coupling with clamps or a solvent weld PVC or ABS coupling.

Vertical Switch Installation
Position the Vertical Float Switch on the discharge pipe so it will turn on when the water level rises above the start level of the primary pump. Make sure the “on” level does not exceed the top of the basin It is recommended to keep at least a 2″ clearance from the top of the basin. You can adjust the “off” level of the vertical float by moving the grommet up or down on the vertical float rod. Once positioned properly, completely tighten the float switch clamp.
NOTE: There are many different options for assembling this unit. The instructions above represent one of the most common installations. Your installation may vary. If you have a very shallow basin, mounting the backup pump above the primary pump may not be feasible. You may also position the pump on the bottom of the basin. Make sure the backup pump is positioned so that it won’t interfere with the primary pump operation. If you have any questions about your particular installation, please feel free to contact us at 1- 888-6-PROFLO (1-888-677-6356)

Wiring & Electrical Connections

1. If necessary, attach the provided battery terminals to the battery (battery is sold separately). Many deep cycle marine & AGM batteries come with a threaded post terminal built-in. NOTE The provided battery terminals are labeled (+) positive and (-) negative. Make sure the terminals are connected to the proper terminal on the battery. Place the battery in the battery box.
2. Connect the battery lead wires from the control panel to the corresponding terminals on the battery. Connect the red (+) positive lead to the positive battery terminal and securely tighten the nut. Connect the black (-) negative lead to the negative battery terminal and securely tighten the nut. Secure the battery box cover to the lower case.
3. Connect the backup pump power cord to the corresponding receptacle on the control panel. Make sure it is fully seated in the receptacle.
4. Connect the backup pump float switch plug to the corresponding receptacle on the control panel. Make sure it is fully seated in the receptacle.
5. Connect the control panel power cord to the side of the control panel. Make sure it is fully seated in the receptacle. Plug the power cord into the outlet.
6. Test the float switch and pump by lifting and holding the float. The alarm will sound and the “PUMP ACTIVATION” light on the control panel will illuminate. The “SYSTEM” light will also change from green to red. The pump should start after lifting the float. If it does not run, check your connections and retry.
7. Test the “MUTE” button when the alarm is sounding. Press once to mute the alarm, or press and hold for 5 seconds to silence the alarm. NOTE: When silencing the alarm press and hold the “MUTE/SILENCE” button until it beeps (approximately 5-6 seconds). This will indicate that the alarm is silenced. To re-activate the alarm, press and hold the TEST/RESET button until it beeps.
8. Secure the float switch and pump cords to the discharge pipe using the provided zip ties. This is to prevent the cords from obstructing the float switches during operation.
   

Installation – Testing installation

1. Once your installation and wiring connections are complete, unplug or disconnect the power to the primary pump.
2. Fill the basin using buckets or a hose. Observe the float switches to make sure they are positioned properly when the basin is filling. Fill the basin until the backup float activates the alarm. The pump should start and drain the basin.
3. Make any necessary adjustments to the float(s) and/or pumps at this lime.

Operation

1. When the power fails or when there is a problem with the primary pump, the backup pump will automatically start. The backup pump will operate for many hours intermittently on battery power. During prolonged periods of a power outage, the pump may stop pumping when the battery voltage drops below 10.8 volts. When this happens the alarm will sound signaling that the voltage is too low to operate the pump.
2. This unit is equipped with a 2 amp charger. It will charge a discharged battery at a rate of 2 Ah (Amp-hours). Once the battery reaches a full charge, the charger will gradually reduce the charge rate. It will also maintain a charged battery by periodically checking the voltage of the battery.
3. The charger is equipped with overcharge protection. It will not let the battery become overcharged.
