GENERAL INFORMATION

The battery back-up sump system is not a substitute for your primary sump pump. It is designed to temporarily back up your primary sump pump during a power outageor other problem which prevents normal operation of the primary pump. Do not use this system to pump flammable liquids or chemicals. Pump clear water only with this pump.

Keep battery charger dry and protected from damage. In an emergency (such as an extended power outage) which depletes the system deep cycle battery, your automobile battery may be temporarily substituted. Be sure to replace the system deep cycle battery as soon as possible. Use of an automobile battery instead of a deep cycle battery in this system will significantly reduce system total performance. Automobile batteries are not designed for this type of application and will be quickly ruined by the repeated charge/discharge cycling. Do not use GEL-type batteries or maintenance-free (sealed) batteries with this charger. GEL-type batteries require a lower voltage than the charger is designed for; they may  overcharge. Maintenance-free (sealed) batteries require ahigher voltage and may never reach full charge.
NOTICE: This unit is not designed for applications involving salt water or brine! Use with salt water or brine will void warranty

Installation

Warning: Personal injury and flood hazard. Do not turn the pump on until all the fittings are glued and the glue has dried. Loose fittings can explode off of pipes and cause personal injury and flooding.
Remove Primary Pump From Sump Pit:

  1. Locate the “on” water level of the primary sump pump. Mark this location on the discharge pipe with a pencil. See Figure 1.

  2. Drain the sump pit. The water level must be pumped down as low as possible before going on to the next step. To drain the sump pit follow either step “2A” or “2B” (below).
    2A. Raise the float on the float switch until the pump turns on. Use a wooden broom handle or a stick to do this.
    2B. If the sump pump has a piggy-back type power cord, remove the float switch power cord plug from the outlet and plug the pump power cord plug directly into the outlet. See Figure 2.
    Warning: Electrical shock hazard. Shock can burn or kill. Do not use metal or any other electrical conducting material to raise the float. Do not make contact with the water in the sump pit. Failure to follow this warning can result in personal injury or death.

  3. Drain the sump.
    NOTICE: Do not let the pump run dry. This will damage the pump.

  4. Unplug the pump.

    Figure 1 – Mark and cut pipe as show

  5. Unplug the “Piggy-back” float switch cord plug and the pump power cord plug from the grounded electrical outlet.

  6. Separate the float switch cord plug from the sump pump cord plug.

  7. Plug the pump power cord plug directly into the outlet.

    Figure 2 – To bypass the float switch

  8. To separate the primary pump from the discharge pipe:
    5A. For applications with hose couplings: remove the coupling clamps with a nut driver.
    5B. For applications without rubber couplings: cut the PVC discharge pipe with a hacksaw above the basement floor, at a comfortable level. New rubber couplings are included for reassembly. See Figure 1 on Page 4.
    NOTICE: The discharge pipe is filled with water. Drain the water from the discharge pipe assembly. Keep the work area dry.
    Caution Risk of pinching hands or fingers. To avoid a hand injury from a collapse of plumbing, support the pipe above the separation before cutting or disassembly. See Figure 1.

  9. Lift the primary pump and discharge pipe assembly out of the sump.
    Warning: Risk of electrical shock. Do not lift the pump by the electrical cord; lift pump only by the lifting ring, discharge pipe, or handle on the pump. Lifting by the cord can damage the cord.

Install Backup Pump

There are two ways to install the Battery Back-up Pump. Method A and Method B. See Figure 3 to determine which method to use. Both methods are acceptable.

Figure 3 – Choose an installation method

Method A
Method A suggests installing both of the pumps on the floor of the sump pit. See Figure 4. The minimum required sump basin diameter, at the bottom of the pit and the recommended depth of the sump basin is 18″. Some additional materials you will need are 2 1-1/4″ 90° elbows and 2 1-1/4″ close pipe nipples.

Backup Pump Installation
(Method A)

Figure 4 – Method A installation diagram

Figure 5 – Remove the pre-assembled check valve

  1. Make the second cut in the discharge pipe at the pencil mark as shown in Figure 1 on page 4, and in Figure 4, on Page 5. Clean the pipe ends with a cloth towel and set the cut-off piece of discharge pipe aside.

  2. Remove the check valve assembly (Key No. 4 on Page 15) from the battery back-up pump (Key No. 5) discharge and set it aside. See Figure 5. The check valve assembly will be used later, during assembly.

  3. Thread a 90° elbow (purchased locally) onto the discharge of the back-up pump.

  4. Wrap the threads of all 3 of the close pipe nipples (Key No. 3) with 2 turns of PTFE pipe thread sealant tape and thread one of them into the elbow. Set the other 2 aside.

  5. Thread the check valve assembly, removed back in step 2, onto the close pipe nipple.
    NOTICE: Make sure the check valve is installed in the correct direction. See the inset drawing in Figure 5.

  6. Thread a close pipe nipple into the other end of the check valve.

  7. Thread the second 90° elbow onto the pipe nipple.

  8. Thread the last pipe nipple into the elbow.

  9. Thread the tee onto the pipe nipple and set this assembly aside.

  10. Install a short length of pipe into the top of the check valve in the primary pump discharge. See Figure 6. NOTICE: There must be a check valve installed in the Primary Sump Pump discharge pipe between the tee and the Primary Sump Pump. This will prevent recirculation into the Primary Pump when the Backup Sump Pump comes on.

    Figure 6 – Back-up pump float switch tether length and discharge pipe

  11. Slip a reducer bushing (Key No. 2A) onto the end of the pipe coming from the primary pump discharge. Do not glue this connection yet. NOTICE: If your discharge pipe diameter is 1-1/4″,you will need to glue the reducer bushings into the tee first and then slip the cut off piece of discharge pipe into the bushing.

  12. Slip the tee and the back-up pump subassembly onto the reducer bushing.

  13. Glue the cut off piece of pipe into the top of the reducer bushing in the top of the tee.Mount the float switch assembly (KeyNo. 7) loosely to the discharge pipe with the cable ties (Key Nos. 7A & 7B). See Figure 6. Approximately 2.5” (63.5 mm) of cord length should be left between the float and the clamp. Do not tighten the cable ties. Adjustments may be needed later.

  14. Skip to the section “Cut the Discharge Pipe”, Page 7.

Method B
Method B suggests installing the back-up pump above the primary sump pump. See Figure 7. The minimum required sump basin diameter for this type of installations 13.5″ at the bottom of the pit, and the minimum recommended depth of the basin is 22″.

  1. Make a second cut in the discharge pipe at the pencil mark made in step 1, on Page 4, and set the cut-off piece of discharge pipe aside. See Figures 1 and 7.

    Figure 7 – Method B installation diagram

  2. Wrap the threads of the close nipple (Key No. 3 on Page 12) counterclockwise with 2 turns of PTFE pipe thread sealant tape and set aside.
    NOTICE: There must be a check valve installed in the Primary Sump Pump discharge pipe between the tee and the Primary Sump Pump. This will prevent recirculation into the Primary Pump when the Backup Sump Pump comes on.

  3. The backup pump (Key No. 6) and check valve assembly (Key Nos. 4 and 5) come preassembled. Thread the close pipe nipple into the check valve.

  4. To thread the tee (Key No. 2B – also included reducer bushings) into the close nipple:  Hold the check valve assembly with the channellocks, insert the screwdriver into the tee for leverage, and tighten the tee with the screwdriver. Finish with the tee in a straight up and down (vertical) position.

  5. Clean the pipe ends with the cloth towel.

  6. Glue the cut-off piece of discharge pipe into the top of the tee.
    NOTICE: If your pipe is 1-1/4″, you will need to glue the reducer bushings into the tee and glue the pipe into the bushing. Place the assembly onto the primary discharge pipe. Do not glue the tee onto the primary pump discharge pipe.

  7. Mount the back-up pump float switch assembly (Key No. 7) loosely to the discharge pipe with the cable ties (Key Nos. 7A & 7B). See Figure 6, on Page 6. Approximately 2.5″ (63.5 mm) of cord length should be left between the float and the clamp. Do not tighten the cable ties. Adjustments may be needed later.

Cut the Discharge Pipe:

  1. Put the double pump assembly into the sump pit.
    NOTICE: The discharge pipe now overlaps the discharge pipe that leads outside.

    Figure 8 – Make the third cut to remove the excess discharge pipe

  2. Mark the discharge pipe where it should be cut. Be sure to leave a 1/4″ air gap between the ends of the pipes. This gap will absorb the noise from vibration and allow for flexibility.

  3. Make the third cut. See Figure 8.

Trial Assembly of Double Pump Assembly in the sump pit:

  1. Connect the discharge pipe to the exterior discharge pipe with the rubber coupling and clamp kit (Key No. 1). Do not tighten the clamps until all the final adjustments are complete.
  2. Make the final adjustments. Make sure the pumps and the switches do not interfere with each other. Make sure there is plenty of room for the float switches to either swing or to move up and down from their “off” to their “on” positions.

Mark and Glue Assembly:

  1. Mark the pipe and the fittings at all the connections with a pencil. These marks will be used as a reassembly guide while gluing to be sure everything is still in the right place and nothing has moved.

  2. Loosen the rubber coupling and clamp connection.

  3. Carefully pull the double pump assembly back out of the pit.

  4. Take the tee assembly off of the primary discharge pipe. Do Not unscrew any of the PTFE pipe thread sealant taped pipe nipple connections.

  5. Clean all the PVC pipe ends with the PVC cleaner.
    Warning

  6. Hazardous fumes. Follow the cement and cleaner manufacturers instructions. Use the PVC cement in a well ventilated area away from fire or flames.

  7. Glue the PVC fittings where indicated by the pencil marks. Wait 10 minutes for the glue to cure.

Final Assembly:

  1. Put the double pump assembly back into the pit.
  2. Install and tighten the rubber coupling and clamp kit.
  3. Make the final float switch adjustments and tighten
    the cable ties.

CHARGER OPERATION

The backup pump will activate automatically when the backup sump water level rises far enough to trip the float switch.

If the power to the charger circuit is interrupted, the length of time that the backup pump will run depends on the Ampere-hour capacity of the battery used, the battery charge level, and the required vertical pumping distance. Extended periods of operation (for example, during an extended power outage) may exhaust the battery. The battery charger will begin charging the battery as long as the battery has a voltage differential of 3 Volts or more.

Recharge Time:
FG100-A1: Approximately 100+ hours to fully recharge a 27M battery in a “dead battery condition”. The approximate recharge time for a 24M battery is 75 hours. FG200-A1: Approximately 19 hours to fully recharge a 27M battery in a “dead battery condition”. The approximate recharge time for a 24M battery is 15 hours. Industrial standards define a “dead battery condition” as 9 Volts or less.

The 5 Stages of the Charging Process for Model Number FG100-A1:
Notice: The LED’s will only illuminate once the AC power has been applied. They will not light up if the charger is not plugged in.

  1. Yellow LED light flashing on and off indicates:
    Prequalification test stage is in progress. Normal duration of this stage ranges from 18 minutes to 27 hours. If a battery has been left in a state of discharge  for long periods this stage may require 27 hours to determine if the battery will even accept a charge.

  2. Yellow LED light continuously on indicates:
    Constant current charge stage. Charger is charging battery at the full rated output. This stage ends when the battery terminal voltage reaches the factory preset voltage level.

  3. Yellow LED light continuously on also indicates:
    Constant voltage charge stage. Battery cells are being equalized.

  4. Green LED light on indicates:
    Float charge stage. Battery is charged and ready for use. Charging has stopped. To maintain a full charge on the battery, the yellow and green LED may alternately turn back on. This means the charger is briefly turning back on to keep the battery voltage from falling below a preset voltage level.

  5. Recycle charge stage:
    The charger automatically initiates a charge cycle that begins with the prequalification test stage. This occurs once the battery has been in the float charge stage for 84 days.

The 5 Stages of the Charging Process for Model Number FG200-A1:
Notice:
The LED’s will only illuminate once the AC power has been applied. They will not light up if the charger is not plugged in.

  1. Yellow “charging”(bicolor) LED flashing slowly indicates:
    A. Prequalification test stage is in progress. The normal  duration of this stage is 20 seconds to 3 minutes. However, if a battery has been left in a state of discharge for long periods or if the initial voltage is less than 10.5 volts, this stage may require 5 hours  to determine if the battery will even accept a charge.

  2. Yellow (bicolor)“charging” LED continuously on indicates:
    Constant current charge stage. Charger is charging battery at full rated output.

  3. Yellow (bicolor)“charging” LED flashing quickly indicates:
    Constant voltage charge stage. Battery cells are being equalized. This could last up to 14.5 hours.

  4. Green (bicolor) “charging” LED indicates: Float charge stage. Battery terminal voltage is reduced to a regulated voltage and battery is being maintained at full charge.

Special Features:

  • The chargers are equipped with reverse battery, short circuit, and “run-away charge” protection.
  • A built-in safety timer starts when the charger enters the Constant Current/Constant Voltage Charge stage  (Yellow LED is continuously on). The FG100-A1system has a 90 hour safety timer and the FG200-A1 system has a 20.5 hour safety timer.
    NOTICE: To reset the charger unplug it from the 120V outlet for 10 seconds and then plug it back in.

BATTERY REQUIREMENTS

Warning Hazardous electrical current. Can cause severe burns and start a fire if battery terminals are short circuited. Install the battery in a battery box (See Key No. 8, Page 15). To prevent accidental shorting across battery terminals, strap cover securely (See Figure 13) on the battery box. Do not leave battery uncovered. Do not allow children to play around the battery backup system installation.

Your backup sump pump depends on the battery used with it for power. The better the battery, the better the performance of the pump. We recommend the use of a size 27M Marine Deep Cycle Battery or a size 24M Marine Deep Cycle Battery. They will perform as indicated in Table IX, on Page 13, and they stand up well to long periods of little or no use.
NOTICE: A 24M battery will provide the same performance as a 27M, but for a shorter length of time.  Use of a standard automobile battery, GEL type, or a   Maintenance Free (sealed) battery with this charger is not recommended. An automobile 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. GEL-type batteries require a lower voltage than the charger is designed for; they may overcharge. Maintenance-free (sealed) batteries require a higher voltage; they may never reach full charge Use only the recommended battery or one of the same
type and size so it will fit in the battery box (maximum size 12-5/8″ long, 7″ wide and 9-3/8″ high [320.7mm x 177.8mm x 238mm] including terminals) and supply enough voltage for full performance.

BATTERY MAINTENANCE

Warning
Severe burn hazard. A filled battery contains sulfuric acid. Avoid contact with skin, eyes or clothing.
NOTICE: To protect battery case from chipping and gouging, do not let battery sit on concrete floor. Install battery on a shelf or protective pad (plywood, 2x4s, etc.).  Always install battery in a dry location that is protected from flooding.
Follow the battery manufacturer’s recommendations for maintenance and safe use of battery.

TROUBLESHOOTING

Pump won’t run.

  1. Check all wiring connections.
  2. Check for low or defective battery.
  3. Check that automatic switch is free to swing up and down.
  4. Check for a blown fuse in the junction box of the FG100-A1 system or in the charger of the FG200-A1 system.

Motor hums but pump won’t run:

  1. Check for low or defective battery.

Pump runs but pumps very little or no water:

  1. Make sure a check valve is installed and functioning
    between primary pump discharge and Backup Sump Pump tee.

  2. Check for obstruction in discharge pipe.

  3. Discharge pipe length and/or height exceeds capacity of pump. See Table IX, Page 13, for pump capacity.

  4. Check for low or defective battery.

  5. Positive (+) and negative (–) wires are reversed.

Pump cycles too frequently:

  1. Tether length too short on automatic float switch. Make sure that tether is at least 2.5″ (63.5mm); see Figure 6, Page 6.
  2. Main check valve located between discharge of primary pump and the Backup Sump Pump tee is not installed or is not working properly. Install or repair as required.
