Introduction

The Basement Watchdog Emergency is a battery-operated backup sump pump system. It is designed as an emergency backup system to support your main AC sump pump, and will automatically begin pumping any time the float switch is activated by rising water. Should any malfunction or emergency occur that involves the sump pump, the battery, or the AC power, the Basement Watchdog system will sound an alarm. A light on the display panel of the control unit will indicate the cause of the alarm and the corrective action.
For added reliability, the float switch has not one but two floats. Should one float fail to operate, the second float automatically activates the pump.
The Basement Watchdog Emergency Sump Pump System includes:

A control unit with a dual float switch and battery cables
A pump with a 1½” PVC pipe adapter
Two (2) plastic wire ties for mounting the float switch and the control unit
A battery box
A battery charger
You will also need to supply:
A Basement Watchdog Maintenance Free (AGM) Standby Battery (BW-27AGM). The internal construction of some batteries may not be compatible with this system. Glentronics cannot guarantee the compatibility of other brands of batteries. The use of a Basement Watchdog battery is HIGHLY recommended. DO NOT use an automotive battery with this system. Save time and money by using the Basement Watchdog Quick Connect Pipe (BW-QCP), a preassembled pipe which may eliminate the need to purchase and use the first 3 bulleted items below.
11/2″ rigid PVC pipe and fittings
PVC cement and primer
A union with hose clamps or a wye connector and two (2) check valves, depending on the installation method you use
A surge protector (recommended) For narrow sump pits you will need some additional parts:
An “L” bracket at least six (6) inches long (preferably one that will not rust)
Two (2) stainlesssteel hose clamps
One (1) stainless-steel screw (#8-32 x ¾”), a matching washer and nut Using a Basement Watchdog Klunkless Check Valve™ (BW-CVK15) will provide quieter operation. (See back cover.)

Pump & Pipe Installation Instructions

There are two basic methods that can be used to install the pump: a direct discharge to the outside of the building or a connection to an existing discharge pipe. The same two options apply in very narrow sump pits where the backup pump must be mounted above the main pump. Use a pit that conforms to all local codes, and check the code to see if a gate valve or ball valve is required.
Whenever possible, install your Basement Watchdog backup pump with a direct discharge to the outdoors. By using this method, an outlet will always exist for the water from the sump. During periods of very heavy rain, many storm sewers fill up. If your pump is trying to discharge water into a full sewer, the water has nowhere to go. By discharging directly outdoors, an outlet always exists for the water that is pumped out of the sump pit. For this method, you will need to drill a hole through a floor joist or the foundation from the basement to the outside of the house.
If the direct discharge method is not possible or convenient, the Basement Watchdog pump can be connected to the same line as your main AC sump pump by installing a wye connector and two (2) check valves. In most cases, the backup pump will fit next to the main AC pump in the sump pit. In very narrow pits, the backup pump can be mounted above the main AC pump. Check to ensure there is enough room so that the backup pump and the main pump do not touch each other before connecting the backup pump.
Before starting the installation, clean the pit of all debris. Place the pump on a pump stand or brick next to the main AC pump, and ensure that both pumps are level and not touching each other.
The stand or brick is used to guard against debris buildup on the bottom of the pit; the pump’s strainer must be kept clear. Select the installation method that will best suit your needs from the diagrams at the right. Full instructions for each installation method are provided on pages 4-7.
Save time, money and make your installation easier by using the Basement Watchdog Quick Connect Pipe (BW-QCP), a preassembled discharge pipe.

Pump & Pipe Installation Instructions
INSTALLATION A:
DIRECT DISCHARGE TO THE OUTSIDE OF THE BUILDING (DIAGRAM A)
DANGER
Unplug the main AC pump when installing the backup pump to avoid electric shock. Failure to do so could cause serious injury or death. Save time and money by using the preassembled Basement Watchdog Quick Connect Pipe BWQCP). If not, follow the steps below:

Cut a piece of 1½” rigid PVC pipe long enough to reach from the bottom of the sump pit to one (1) foot above the floor. Prime and cement it to the 1½” pipe adapter, then screw the adapter into the pump.
Secure the pump wire so that the plug on the end will not fall into the sump. Attach the wire to the pipe with a piece of tape. 3. Clean the pit of all debris. Place the pump with the PVC pipe attachment on a pump stand or brick next to the main AC pump, NOT directly on the pit floor. This stand or brick is used to guard against debris buildup on the bottom of the pit. The pumps should not touch each other. Pump should be level.
Attach a union or a check valve to the top of the 1½” pipe. This will allow the pump to be removed easily if needed.

The path of the rest of the pipe and the details of each installation will vary. Using sound plumbing practices, route the discharge pipe to an exterior wall via the shortest path with the fewest turns. More turns will reduce the pumping capacity. The pipe section exiting the building should be on a downward slope so that the water in the pipe will exit outside instead of returning to the sump pit. Seal the hole in the wall where the pipe exits, and prime and cement or clamp all connections securely to prevent leaking. (Although a check valve is recommended, one is not required with this method of installation as long as you use less than 15 feet of pipe.)
CAUTION
If you use more than a total of 15 feet of pipe (including vertical and horizontal runs) in the installation, install a check valve in place of the union. Make sure it is installed with the arrow pointing

up (see photo at top right), or it will not prevent the backflow of water. When a check valve is used, a 3/16″ hole must be drilled in the PVC pipe above the Basement Watchdog pump. Drill the hole at a 45° angle upwards (see photo at far right) toward the bottom of the sump to avoid splashing water outside the sump pit. Make sure the hole is above the water line and below the check valve.
If a hole is not drilled above the pump, an air lock may prevent the pump from operating.

INSTALLATION B:
CONNECTION TO AN EXISTING DISCHARGE PIPE (DIAGRAM B)
Depending on your installation requirements, PVC pipe lengths will vary. Cut the pipes and assemble them as shown in photo #7. Do not cement them together until you are sure they are cut to the correct lengths. It is important to keep the discharge pipes on both pumps parallel to each other so that the pumps remain flat on the floor of the sump. More detailed instructions follow.
DANGER
Unplug the main AC pump when installing the backup pump to avoid electric shock. Failure to do so could cause serious injury or death.

Cut a piece of 1½” rigid PVC pipe long enough to reach from the bottom of the sump pit to one (1) foot above the floor. Prime and cement it to the 1½” pipe adapter, then screw the adapter into the pump.
Install a check valve on the top of the PVC pipe attached to the Basement Watchdog pump. Make sure it is installed with the arrow pointing up or it will not prevent the backflow of water.
CAUTION
When a check valve is used, a 3/16″ hole must be drilled in the PVC pipe above the Basement Watchdog pump. Make sure it is above the water line and below the check valve. Drill the hole at a 45° angle upward to avoid splashing water outside the sump pit. If a 3/16″ hole is not drilled in the pipe above the pump, an air lock may prevent the pump from operating.
If there is no check valve on the discharge pipe of the main AC pump below the tie-in point, one must be installed at this time. Cut the discharge pipe approximately one (1) foot above the floor. Install a check valve on the top of the pipe and tighten the bottom hose clamp. Now prime and cement a small piece of 1½” PVC pipe to the bottom of a wye connector. Prime and cement the top of the wye assembly to the discharge pipe with the wye extension facing down toward the backup pump. Next, connect the bottom of the assembly to the check valve and then tighten the hose clamp.
CAUTION Failure to install a check valve between the wye connector and the main AC pump will cause the main system to not operate properly. A 3/16″ hole must also be drilled in the PVC pipe above the pump. (See photo 3 at top right.)
Secure the pump wire so that the plug on the end will not fall into the sump. Attach the wire to the pipe with a piece of tape.
Clean the pit of all debris. Place the pump with the PVC pipe attachment on a pump stand or brick next to the main AC pump, NOT directly on the pit floor. This stand or brick is used to guard against debris buildup on the bottom of the pit. The pumps should not touch each other. Pump should be level.
Connect a piece of 1½” PVC pipe above the check valve of the Basement Watchdog pump, and attach a 45° elbow to that pipe. Extend another piece of pipe to reach from the 45° elbow to the wye connector on the other pipe.
Prime and cement all pipe connections securely to prevent leaking, and tighten all the hose clamps.

INSTALLATION C:
DIRECT DISCHARGE TO THE OUTSIDE OF THE BUILDING FOR NARROW SUMP PITS (DIAGRAM C)
DANGER
Unplug the main AC pump when installing the backup pump to avoid electric shock. Failure to do so could cause serious injury or death.

Attach an “L” bracket to the discharge pipe of the main AC pump with two (2) stainless-steel hose clamps. Position the bracket so the bottom of the “L” is just above the top of the main pump, and out of the way of any float switch on the main pump.
(a) Remove the black bottom strainer of the pump by pressing in the two tabs on the strainer and pushing down. There are holes suitable for mounting on the bottom of the strainer. (b) Using the #8-32 x ¾” stainless-steel screw, washer and nut, attach the strainer to the “L” bracket. (c) Once the strainer is attached, simply press the rest of the pump onto the mounted strainer.
Secure the pump wire so that the plug on the end will not fall into the sump. Attach the wire to the pipe with a piece of tape. Save time and money by using the Basement Watchdog Quick Connect Pipe (BW-QCP), a preassembled discharge pipe (see page 2). If not, continue the following steps:
Cut a piece of 1½” rigid PVC pipe long enough to reach from the elbow of the backup pump to one (1) foot above the floor. Prime and cement it to the 1½” pipe adapter, and then screw the adapter into the pump.
Attach a union or check valve to the top of the 1½” PVC pipe. This will allow the pump to be removed easily, should the need arise. The path of the rest of the pipe and the details of each installation will vary. Using sound plumbing practices, route the discharge pipe to an exterior wall via the shortest path with the fewest turns. More turns will reduce the pumping capacity. The pipe section exiting the building should be on a downward slope so that the water in the pipe will exit outside instead of returning to the sump pit. Be sure to seal the hole in the wall where the pipe exits, and prime and cement or clamp all connections securely to prevent leaking. (Although a check valve is recommended, one is not required with this method of installation as long as you use less than 15 feet of pipe.)

CAUTION
If you use more than a total of 15 feet of pipe (including vertical and horizontal runs) in the installation, install a check valve in place of the union. Make sure it is installed with the arrow pointing up or it will not prevent the backflow of water. When a check valve is used, a 3/16″ hole must be drilled in the PVC pipe above the Basement Watchdog pump. Drill the hole at a 45° angle upward to avoid splashing water outside the sump pit. Make sure the hole is above the water line, and below the check valve. If a hole is not drilled above the pump, an air lock may prevent the pump from operating.

INSTALLATION D:
CONNECTION TO EXISTING DISCHARGE PIPE FOR NARROW SUMP PITS (DIAGRAM D)
Depending on your installation requirements, PVC pipe lengths will vary. Cut the pipes and assemble them as shown in photo 8 below. Do not cement them together until you are sure they are cut to the correct lengths. It is important to keep the discharge pipes on both pumps parallel to each other, so that the pumps remain flat on the floor of the sump. More detailed instructions follow.
DANGER
Unplug the main AC pump when installing the backup pump to avoid electric shock. Failure to do so could cause serious injury or death.

Attach an “L” bracket to the discharge pipe of the main AC pump with two (2) stainless-
steel hose clamps. Position the bracket so the bottom of the “L” is just above the top of the main pump, and out of the way of any float switch on the main pump.
(a) Remove the black bottom strainer of the pump by pressing in the two tabs on the strainer and pushing down. On the bottom of the strainer are holes suitable for mounting. (b) Using the # 8-32 x ¾” stainless-steel screw, washer and nut, attach the strainer to the “L” bracket. (c) Once the strainer is attached, simply press the rest of the pump onto the mounted strainer.
Secure the pump wire so that the plug on the end will not fall into the sump. Attach the wire to the pipe with a piece of tape. Save time and money by using the Basement Watchdog Quick Connect Pipe (BW-QCP), a preassembled discharge pipe. (See page 2.) If not, continue the following steps:
Cut a piece of 1½” rigid PVC pipe long enough to reach from the elbow of the backup pump to one (1) foot above the floor. Prime and cement it to the 1½” pipe adapter, then screw the adapter into the pump.
Install a check valve on the top of the PVC pipe attached to the Basement Watchdog pump. Make sure it is installed with the arrow pointing up or it will not prevent the backflow of water.
CAUTION
When a check valve is used, a 3/16” hole must be drilled in the PVC pipe above the Basement Watchdog pump. Make sure it is above the water line and below the check valve. Drill the hole at a 45° angle upward to avoid splashing water outside the sump pit. If a 3/16″ hole is not drilled above the pump, an air lock may prevent the pump from operating.
If there is no check valve on the main AC pump discharge pipe, one must be installed at this time. Cut the discharge pipe approximately one (1) foot above the floor. Install a check valve on the pipe and tighten the bottom hose clamp. Now prime and cement a small piece of 1½” PVC pipe to the bottom of a wye connector. Prime and cement the top of the wye assembly to the discharge pipe with the wye extension facing down toward the backup pump. Now connect the bottom of the assembly to the check valve and tighten the hose clamp.
CAUTION
Failure to install a check valve between the wye connector and the main AC pump will cause the main system to not operate properly. A 3/16″hole must also be drilled in the PVC pipe above the pump (see photo 6).
Connect a piece of 1½” PVC pipe above the check valve of the Basement Watchdog pump, and attach a 45° elbow to that pipe. Extend another piece of pipe to reach from the 45° elbow to the wye connector on the other pipe.
Prime and cement all pipe connections securely to prevent leaking, and tighten every hose clamp.

Battery Instructions

The Basement Watchdog Maintenance Free (BW27AGM) Standby Battery has been designed to run this system for 80 hours, based on a 10% duty cycle. However, most of the time the pump will turn on and off, and the battery will run the pump intermittently for days. In addition, the unique materials in the battery enable it to last longer in standby service.
CAUTION

The use of automotive batteries is NOT recommended. Automotive batteries are not designed for this application. They will only run the pump for a short time and will have a shorter life than a standby battery.
The internal construction of some batteries may not be compatible with this system. The use of a Basement Watchdog battery is HIGHLY recommended.

Control Unit Connections
DANGER
Risk of electrical shock or battery explosion, which can cause serious injury or death. Unplug the main AC pump to avoid electrical shock. Wear eye protection. Work in a well-ventilated area. Do not smoke or allow a spark or flame in the vicinity of the battery. Avoid dropping metal tools on the battery. If battery acid contacts eyes, flush with water for 15 minutes and get prompt medical attention. Review the safety instructions on page 1.
When you position the control unit on the discharge pipe, be sure the charger cord will reach the AC power outlet (a surge protector is recommended), and the pump cable and float switch will reach the bottom of the sump. Position the unit in a well-ventilated area. (Diagram F) Do NOT place anything on top of the battery.

Mounting the control unit: (a) Thread one plastic wire tie through the two mounting brackets on the back of the control unit. (b) Secure the controller to the discharge pipe of the Basement Watchdog pump by wrapping the tie around the pipe and pulling it tight.
Positioning the dual float switch: (a) The float switch wire includes a connector that can be separated from the controller when the wire needs to be threaded through small openings such as a sump pit cover. Be sure the float switch wire connection is secure before final installation. (b) The float switch will activate the pump when the water raises either float, and it will remain running as long as the water is above the float. When the water drops below the float switch, an internal timer in the control unit will keep the pump running about 25 seconds to empty the sump pit. The switch should be mounted about six (6) inches above the water level line in the sump pit. Attach the float switch very securely to the discharge pipe with the plastic wire tie. Be sure the switch is positioned vertically with the mounting bracket at the top. Do not tilt the switch. Do not position the float switch on the side of the discharge pipe facing the drain tile or any incoming rush of water!
Connecting the pump: Remove the security tag from the pump and plug the pump wires into the pump connector on the back of the control unit. Keep the backup pump wire, the AC pump wire, and the float wire separate from each
other. Do not let them cross on the final installation.
Connecting the battery: Attach the battery cables to the battery—the Red wire to the POSITIVE (+) post and the BLACK wire to the NEGATIVE (-) post. Replace the battery bolts and tighten them.
Connecting the charger: Immediately plug the charger into the CHARGER port on the back of the control unit, then into an AC outlet on the wall. (You should provide additional protection for the control unit by using a surge protector).
If the pump alarm is sounding, press the RESET button to silence the alarm.
Secure the cover on the battery box by slipping the tabs through the fittings on the front and back of the box.
Check the pump operation by filling the sump with water and observing the pump through several full cycles.
BE SURE TO PLUG IN THE MAIN AC PUMP WHEN YOU COMPLETE THE INSTALLATION.

Understanding the Warnings & Alarms
The Basement Watchdog control unit features a series of warning lights that pinpoint potential problems. In addition, an alarm sounds to alert you to issues. In some cases the lights and alarm will go off automatically when the problem has been resolved. In others, the RESET button must be pushed to silence the alarm. Refer to the table (page 9) for a quick review of the features and their corresponding alarm status.

Warning| Alarm can be silenced before problem is corrected| Alarm shuts off automatically when the problem is corrected
---|---|---
Power Alarm| Yes| Yes
Pump Alarm| Yes| No, push the RESET button
System Light| No alarm| No alarm
Battery Alarm| No| Yes

SILENCING THE ALARM DURING AN EMERGENCY
The Basement Watchdog Emergency system is equipped with a switch that will silence the audible alarm during an extended emergency. The “Power” 1 and “Pump” 2 alarms can be silenced during a power outage or during heavy rains when the pump is activated repeatedly.
To silence both the “Power” and “Pump” alarms, slide the “Audible Alarm” switch to OFF. The “Power” and/or the “Pump” light will remain on, but the audible alarm will not sound. When the emergency has ended, slide the switch to the ON position to resume the full monitoring capability, or you will not be warned the next time an emergency occurs. The “Battery” 4 alarm cannot be silenced. It requires immediate attention.
Power There are several causes for power failure. The most common is a power outage by your electric company. During this emergency, the Basement Watchdog system will automatically switch to battery power and protect your basement from flooding.

You can silence the ”Power” alarm by sliding the “Audible Alarm” switch to OFF. The alarm will be silenced, but the light will stay on. The system will continue to operate while the power alarm is silenced. Be sure to slide the switch to the ON position when the power is restored to resume full monitoring capability.

If the power is on in the rest of the house, check the home circuit breaker or fuse box for failure, and correct the problem.
Check the charger. Make sure it is securely plugged into the wall outlet. Ensure the power outlet is working and the GFCI has not tripped.
Check the charger plug that fits into the rear panel of the control unit. Make sure it is securely plugged into the control unit.

The control unit must receive 115 volts AC +/- 5% from the AC outlet. Voltage lower than 110 volts will activate the “Power” alarm. Lower voltages can be caused by utility company brownouts or a heavy power draw from other appliances on the same circuit. Reduce the number of appliances on the circuit.
If all the connections are secure and the wall outlet is operating but the ”Power” warning light is still on, replace the charger unit with a new Basement Watchdog charger (part number 1015003). Contact Glentronics at 800-991-0466, option #3.
2 Pump
When the water rises in the sump pit and activates the float switch, the pump will begin pumping, and the “Pump” light and alarm will turn on. The alarm stays on to alert you to the fact that the standby system was used to empty water from the sump. Try to determine what caused the system to activate.

Check the main AC pump for failure. It may not be working, the float switch may be stuck, or it may be too small to handle the inflow of water.
Make sure the check valve is working and installed correctly.
Ensure the discharge pipe is not clogged or frozen.
If the power was out, the backup pump was automatically activated. You need to push the RESET button on the front of the control panel to reset the alarm.

During a power outage or times when the pump is activated repeatedly, you can temporarily silence the alarm by sliding the “Audible Alarm” switch to OFF. WHEN THE PRIMARY PUMP HAS RESUMED NORMAL OPERATION, AND THE BACKUP PUMP IS NO LONGER ACTIVATING REPEATEDLY, SLIDE THE

SWITCH TO THE ON POSITION TO RESUME THE FULL MONITORING CAPABILITY. The alarm and pump light will still be on. Push the RESET button on the front of the control panel to silence the alarm. REPLACING THE PUMP
DANGER
Unplug the main AC pump when installing or servicing the backup pump to avoid electric shock. Failure to do so could cause serious injury or death. Review the safety instructions on page 1.
REFER TO PHOTOS BELOW AND ON NEXT PAGE

Unplug the charger from the wall outlet.
Remove the cover of the battery box by pushing in the tabs on the front and back, then lifting up.
Fan the area around the top of the battery with a piece of cardboard (or another nonmetallic material) to remove any hydrogen or oxygen gas that may have been emitted from the battery.
Remove the battery cables from the battery.
Unplug the pump from the back of the control unit.
Release the union or check valve and remove the pump and the rigid PVC pipe section from the sump pit.
Unscrew the pipe and adapter from the old pump, and screw them into the new pump.
Clean the pit of all debris. Place the pump on a pump stand or brick next to the main AC pump, and ensure that both pumps are level and not touching each other. The stand or brick is used to guard against debris buildup on the bottom of the pit; the pump’s strainer must be kept clear. Pump should be level.
Lower the pump into the sump and reconnect the union or check valve.
Plug the pump wires into the back of the control unit.
Connect the battery cables to the battery— the RED wire to the POSITIVE (+) post and then the BLACK wire to the NEGATIVE (-) post. Tighten the battery bolts.
Replace the cover of the battery box.
Check the pump operation by filling the sump with water and observing the pump through several full cycles.
Plug the charger and the main AC pump back into the wall outlet. (You should provide additional protection for the controller by using a surge protector).
If any alarms are sounding, press the RESET button on the front of the control unit for one (1) second to silence them.

3 System
This green light should always be flashing. It indicates that the system is operating. It will flash when the system has power, either coming from the battery or the AC outlet.
4 Battery
This light and alarm will come on when the control unit detects there is less than ½ hour of continuous pumping power left in the battery, or that the battery is defective. The alarm cannot be silenced as action needs to be taken to protect your basement. If your battery is more than five ( 5 ) years old, replace it. If not, several situations could cause the pump to run the battery for an extended time and discharge the battery.
Check the following list before you replace the battery:

If the top light on the controller is also on, it means that the unit is not receiving AC power. Either the AC power is out, the circuit breaker has blown, or the outlet is bad. When the problem is corrected, the battery should recharge.
If the second light on the controller is also on, check your main pump for failure. The backup pump may have been activated repeatedly if your main AC pump is broken, or you are experiencing heavy rains and your main pump cannot keep up with the inflow of water. You may need to upgrade or replace your main pump. When the problem is corrected, the battery should recharge.
If no other lights are on, this means the terminals may be corroded, and the battery cannot charge properly. Unplug the charger from the wall outlet. Then check the battery cables and the battery terminals for corrosion. Clean and tighten as needed. This process is described to the right and on page 11.
If the battery terminals have been cleaned and the light is still on, the problem could be with the controller or battery. The best way to determine if the battery is the problem is to have it charged and load tested at any local auto supply, auto repair or battery store. If the battery is bad and less than one (1) year old, call Glentronics (receipt required). If the battery is good, also contact Glentronics’ service department for further instructions. The phone number is 800-991-0466, option #3.
If the battery alarm goes on while the pump is running and the power is out, you will have a minimum of one-half (½) hour of continuous pumping time to replace the battery. (In most cases, the pump does not run continuously, and therefore, you actually have a longer time to replace it.) You will not be able to silence the alarm. Left unattended, the basement will flood. In a severe emergency, if a replacement battery is not available, recharge this battery by connecting it to your car battery and turning the car on. Once the AC power is restored, the battery will recharge automatically, unless it is old or damaged. The alarm will turn off when the AC power is restored and the pumping energy reaches one-half (½) hour or more. In the event that your Basement Watchdog sump pump system has pumped for an extended period of time, the battery may be very depleted. In this condition, when the AC power is returned to the unit, a battery alarm will continue to sound. The battery may need 24 to 48 hours to recharge. For a faster recharge, an automotive or marine battery charger can be used to recharge the battery. Follow the manufacturer’s instructions and safety information included with the charger.

WARNING
When another charger is used, first disconnect the Basement Watchdog charger from the control unit, and then disconnect the control unit from the battery. Using another charger without disconnecting the control unit will destroy the control unit and void the warranty. HOW TO CLEAN THE BATTERY TERMINALS AND CABLES
DANGER
Risk of electrical shock or battery explosion, which can cause serious injury or death. Wear eye protection. Work in a well-ventilated area. Do not smoke or allow a spark or flame in the vicinity of the battery. Avoid dropping metal tools on the battery. If battery acid contacts eyes, flush with water for 15 minutes and get prompt medical attention. Review the safety instructions on page 1. REFER TO THE PHOTOS ON PAGE 11

Unplug the charger from the wall outlet.
Remove the cover of the battery box by pushing in the tabs on the front and back, then lifting up.
Fan the area around the top of the battery with a piece of cardboard (or another nonmetallic material) to remove any hydrogen or oxygen gas that may have been emitted from the battery.
Remove the battery cables.
Clean the battery bolts with a battery terminal cleaner or a wire brush.
Clean any corrosion off of the ring connectors on the ends of the battery wires. Use a stiff brush or sandpaper.
DO NOT apply corrosion-resisting sprays or pads to the terminal rings or posts after you have cleaned them, since this could prevent the battery from charging properly.
Replace the battery cables, RED to the POSITIVE (+) post and then BLACK to the NEGATIVE (-) post. Tighten the battery bolts.
Secure the cover on the battery box by slipping the tabs through the fittings on the front and back of the box.
Plug the charger back into the wall outlet. (You should provide additional protection for the control unit by using a surge protector.)
If any of the alarms are sounding, press the RESET button on the front of the control panel for one (1) second.

REPLACING THE BATTERY
DANGER

REFER TO THE PHOTOS AT RIGHT

Unplug the charger from the wall outlet.
Remove the cover of the battery box by pushing in the tabs on the front and back, then lifting up.
Fan the area around the top of the battery with a piece of cardboard (or another nonmetallic material) to remove any hydrogen or oxygen gas that may have been emitted from the battery.
Remove the battery cables.
Remove the old battery from the battery box and place the new battery in the box.
Clean any corrosion off of the ring connectors on the ends of the battery wires. Use a stiff brush or sandpaper. DO NOT apply corrosion-resisting sprays or pads to the terminal rings or posts after you have cleaned them, since this could prevent the battery from charging properly.
Replace the battery cables, RED to the POSITIVE (+) post and BLACK to the NEGATIVE (-) post. Tighten the battery bolts.

If any of the alarms are sounding, press the RESET button on the front of the control panel for one (1) second.

TEST/RESET BUTTON
The TEST button may be used to check the pump and system. Push the TEST button.
This will activate the pump for as long as you hold the button. It will stop as soon as you let go of the button.
While the pump is active, water will come out of the ³/₁₆” hole that was drilled into the PVC discharge pipe. This is normal. This hole is needed to prevent an air lock within the system. DO NOT obstruct the hole or an air lock may prevent the system form activating.
TESTING THE FLOAT SWITCH
It is important to manually test the float switch periodically or after any maintenance.
DANGER
Unplug the main AC pump when installing or servicing the backup pump to avoid electric shock. Failure to do so could cause serious injury or death. Review the safety instructions on page 1.

Lift the float up and let go. This will activate the pump. The control unit will run the pump for approximately 25 seconds so it can empty all the water in the sump pit. While the pump is active, water will come out of the ³/₁₆” hole that was drilled into the PVC discharge pipe. This is normal. The hole is needed to prevent an air lock within the system. DO NOT obstruct the hole or an air lock may prevent the system from removing water. If there is no water in the pit, the ump can run dry for this amount of time. The alarm will sound and the “Pump” light will go on. Push the RESET button on the front of the control panel to reset the alarm. BE SURE TO PLUG IN THE MAIN AC PUMP WHEN YOU HAVE COMPLETED THE TEST.

MAINTENANCE CHECKLIST

Maintenance should be performed 1-2 times per year.

Lift the float switch as described at left.
Remove all debris from the bottom of the pit and pump strainer.
Remove all debris from the water.
Remove all debris from the float switch.
Fill the pit with water. Make sure the pump turns on at the intended level.
While the pump is running, make sure the pump is evacuating water at a good pace and water is coming out of the ³/₁₆” air bleed hole.
Check and clean battery terminals.
