CARBON MONOXIDE DETECTORS
Whether you have a Zoeller Backup Pump System, or a competitive brand, all use batteries that 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 Company recommends moving the battery as far apart from the CO detector as possible or, if necessary,
vent the battery to the exterior. Zoeller Company 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 and ask for recommendations as to what can be done to prevent the alarm activation.

LCD DISPLAY AND KEYPAD FUNCTIONS
There are two buttons on the front of the charger:
• The scroll button is used to cycle through the information on the LCD screen.
• The alarm reset button:
° Can be pressed to clear alarm buzzer, light and/or display.
° Can be held for longer than 3 seconds to silence the buzzer for a 24-hour period.
The LCD screen will display information about the system by simply hitting the scroll button:
• The bottom line of the LCD will always display the battery voltage and current going to the battery, if charging.
• The alarm screen shows current alarms.
• The cycle counter screen shows how many times the DC float has been activated.
• The AC power loss counter screen shows how many times the AC power has been removed from the charger.
• Optional: a screen may also show the name and number of a service provider.
The 6 LED lights also display information about the charger at a glance:
• The red AC power light will be on if AC power is connected, and it will blink if AC power is not connected.
• The green charged light indicates a full battery, ready for operation.
• The yellow charging light indicates power going to the battery.
• The red low battery light blinks when the battery is below 10.8 volts and rapidly blinks when the battery is below 8.4 volts.
• The yellow pump cycled light will blink when the float is activated, and becomes solid after 3 seconds.
NOTE: The pump activates when float activates. Alarm is delayed to reduce nuisance alarms.
• The yellow alarm off light indicates the buzzer is currently silenced.
