General Information – All Models
The battery back-up sump pump system is not a substitute for your primary sump pump. It is designed to temporarily
back up your primary sump pump during a power outage or 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 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 a higher voltage and may never reach full charge.
•
Hazardous Voltage. Can cause severe or fatal electrical shock. Do not plug in or unplug the battery charger while
standing on a wet floor or in water. Be sure one hand is free when plugging in or unplugging the charger. If
basement floor is wet, disconnect power to basement before walking on floor.
•
DO NOT bypass grounding wires or remove ground prong from attachment plugs.
•
Risk of electric shock. Always disconnect the pump from the power source before handling or making
adjustments.
•
Battery acid is corrosive. Do not spill on skin, clothing, or battery charger. Wear eye and head protection when
working with the battery. Connect and disconnect DC output terminals only after removing the charger from the AC
outlet. Never allow the DC terminals to touch each other.
•
To avoid danger of fire or explosion, keep sparks and flame (pilot light) away from battery.
•
The electrical connections and wiring for a pump installation should only be made by qualified personnel.
•
This pump is supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of
electric shock, be certain that it is connected only to a properly grounded, grounding-type 15 Amp receptacle. A
ground fault circuit interrupter (GFCI) is recommended for use on any electrical appliance submerged in water.
•
DO NOT use an extension cord.
•
The electrical outlet shall be within the length limitations of the pump power cord, and at least 4 feet above floor
level to minimize possible hazards from flood conditions.
•
The installation must be in accordance with the National Electric Code, Uniform Plumbing Code, International
Plumbing Code, as well as all applicable local codes and ordinances.
•
Sump and sewage pumps often handle materials which could cause illness or disease. Wear adequate protective
clothing when working on a used pump or piping.
•
Keep clear of suction and discharge openings. To prevent injury, never insert fingers into pump while it is plugged
in.
•
DO NOT use this product for flammable or corrosive liquid.
•
DO NOT use this product in applications where human contact with the pumped fluid is common (such as
swimming pools, fountains, etc.)
•
NEVER dispose of materials such as paint thinner or other chemicals down drains, as they can chemically attack
and damage pump components, potentially causing product malfunction or failure.
• Use this system only for backup sump pump duty in a residential application. It is not designed as a primary sump
pump.
• Risk of flooding. DO NOT run pump dry. To do so will damage seals and can cause leaking and property damage.
• DO NOT use pumps in water over 140°F (60°C).
• DO NOT use pumps in mud, sand, cement, oil or chemicals.
