Carbon Monoxide Detectors

Whether you have an Aquanaut ® Battery Backup Sump Pump System or a competitive brand, all batteries give off gaseous by-products when charging. Some of these by-products can produce a rotten egg odor. Also,  some of these by-products can cause a CO detector to falsely activate. In order to help prevent false activation, Zoeller recommends moving the battery as far apart from the CO detector as possible or, if necessary, vent the battery to the exterior. Zoeller provides the previous statements only as guidelines to help prevent false activation of the CO detector. In no way are they meant to supersede the instructions that accompany the detector nor do they supersede advice from the CO  detector manufacturer.If the audible alarm associated with your CO detector is activated, we recommend the following actions:

  1. Take immediate action for personal safety as recommended in the CO detector literature.
  2. Contact the appropriate agency to determine if the CO is being produced by your furnace, water heater, or any other device which uses natural gas.
  3. If you are certain that no CO is being produced, then a charging battery may be producing gaseous by-products which are causing the CO detector to activate. Contact the manufacturer of the CO detector,  and ask for recommendations as to what can be done to prevent the alarm activation.

Ten Helpful Hints For Easy Installation

  1. Remove all debris from the pit before installation.
  2. Use a deep cycle battery only. Refer to battery descriptions on page 6.
  3. Be sure the pump is on a firm, level surface.
  4. Install a serviceable check valve in the discharge line.
  5. Test the unit immediately after installation. Refer to STEP 6.
  6. The battery & charger should be placed on a shelf.
  7. Check float On/Off levels per STEP 2 of instructions.
  8. Apply grease to the Positive and Negative terminals of the battery to prevent corrosion.
  9. Check the battery water level once a month and add distilled water as necessary.
  10. Obtain model number, date code, and installation instructions before calling the factory.

Do’s And Don’t’s For Installing A Unit

Note: Aquanaut ® II (Model 585) data was developed with the charger supplying DC power to the pump.

STEP 1: Placement of the Pump in the Pit

Note: If your pet has a cover, then it will have to be modified to accept the Aquanaut ®.

1.1)Inspect the pit for debris and clean as necessary

1.2) Place the pump in the pit making certain that it is on a stable level surface. Refer to Figure 1.1.IMPORTANT: If this pump is to be used as a backup to your primary pump, then make certain that there is no interference between the two pumps.The motor is not watertight. It should NEVER be below floor level.If necessary, bricks or similar materials can be placed under the Aquanaut ®.NOTICE: This product is meant to be used as a battery backup pump to your primary pump only. Consult the factory for advice before installing this unit as a primary pump.

STEP 2: Float Stop Adjustment

2.1) With the pump in the pit, measure the desired float stop on/off positions as shown in Fig. 2.1. These two dimensions will determine the on/off levels of the pump. The spacing between the upper and lower stops will determine the amount of water removed from the pit.Note: It may be necessary to raise the float rod guide to adjust the stops to the dimensions determined in Step 2.1.CAUTIONThe float rod guide should NEVER be between the upper and lower stop.2.2) Remove the pump from the pit and adjust the float stops as necessary. Tighten all screws.Note: If a brick or similar material has been used to raise the pump in the pit, it will be necessary to account for the thickness of the brick.

STEP 3: Installation of the Discharge Piping3.1) Assemble the discharge pipe into the pump as shown in Figure 3.1.IMPORTANT: In order for this installation to work properly, a check valve must be installed onto the discharge line.P/N 30-0100}P/N 30-0101}P/N 30-0102}P/N 30-0103}Recommend the following Zoeller check valves: Some local codes require union check with ball valve.

STEP 4: Electrical Connections for Model 5854.1) Complete electrical connections as shown in Figure 4.1.CAUTIONDo not place the battery or charger directly on the ground. If the battery or charger must be placed directly on the ground, then place a piece of wood between the units and the ground. Do not put the charger on top of the battery.

STEP 5: Testing of Pump Operation

6.1) Unplug the primary pump so that it does not start.6.2) fill the pit with water until the Aquanaut ® starts.6.3) Verify that the pump starts and stops at the desired on/off points.6.4) Verify that there are no leaks in the discharge line.6.5) If adjustment is necessary, raise or lower the appropriate stop(s) according to STEP 2.IMPORTANT: Spacing between upper and lower stops determines the amount of water removed from the pit.6.6) If the pump is not operating properly after following the above steps, refer to the Troubleshooting guide on page 8.6.7) When finished testing plug the primary pump back into the AC receptacle.

Operation of the Aquanaut ® Charger

The charger automatically monitors and charges your battery. In the event of a power outage, the pump will be powered by the battery. Once line power is restored, the charger will recharge the battery. If there is a failure of the primary pump, the charger will supply power to the pump through the battery if line power is present; otherwise, the battery will take over until the problem has been corrected.The lights on the front panel of the charger indicate the state of the system:The red light Indicates that AC line power is present.The green light indicates that the battery is charged to 12V DC*.During periods of an extended power outage, the charge on the battery may drop below 12V DC which would cause the green light to go out. This is normal. The green light will be illuminated once the charger restores the voltage level to 12V DC.The yellow light indicates that the battery is charged above 8V DC.If the yellow light is not illuminated, it indicates that the charge on the battery is below 8V DC. If the line power is out, the pump may have depleted the battery due to normal operation. If there has been no power outage and the primary pump is working properly, it may indicate that the battery is defective or that the controller is defective. Refer to the Troubleshooting guide on page 8 for further instructions.If the Green and Yellow lights flash intermittently, refer to Section G in the Trouble Shooting Guide on page 8.*Voltage is only one indicator of the state of the battery and does not reflect the true condition of the battery. Use a hydrometer to more accurately determine the condition of the battery.

Operation of the Audible Alarm

All Aquanot ® pump systems are equipped with an alarm that sounds when the pump is activated. The alarm will automatically silence when the pumping cycle is completed.Activation of the audible alarm indicates that the primary pump has failed or line power to the primary pump is not present. Whenever the alarm is activated the primary pump and outlet should be inspected.The On/Off switch, located on the side of the alarm enclosure, allows the audible alarm to be turned off, however, this practice is not recommended. Verify that the alarm switch is in the “on” position, by manually turning the pump “on”.

The Aquanaut ® Battery

There are millions of batteries manufactured each year, so it is impossible to guarantee consistent quality. A defective battery will never become fully charged and may damage the circuits of the charger. It is for this reason that Zoeller offers its own line of batteries. We offer two types of batteries; Water/Acid Deep-Cycle,  and AGM – both power the pump continuously for over 3-1/2 hours. These times are based on continuous pumping at 10’ of static head. Actual times will vary depending on the static head, the volume of water entering the pit, and the condition of the battery.Follow these recommendations:

  • Use a B.C.I. size 27, 29, or 31 deep-cycle battery, 175-minute reserve capacity, or larger.
  • Do NOT use a “maintenance-free” battery unless it is an AGM battery.
  • Replace your battery every 3 years.
  • Do not let corrosion build up on the battery terminals.
  • Do not place your battery on a concrete floor where it will discharge faster.
  • To check specific gravity, follow the instructions on a hydrometer (not applicable for AGM batteries).PROTECT YOUR WARRANTY:
  • The water level in batteries must be checked once a month (not applicable for AGM batteries).
