The DC emergency pump is designed as a backup to your primary sump pump during unexpected power outages or primary pump failure. The DC pump,
electronic controls and all the parts required for installation are included except the battery which is supplied by the user. The system is designed for
installation in sumps with minimum of 18" (457 mm) diameter and 24" (610 mm) deep. For 18" x 22" (457 mm x 559 mm) applications, consult factory.
DESCRIPTION
The DC emergency pump system requires a good quality, 12 volt battery to obtain maximum pumping time during a power outage. A deep-cycle, 12
volt, 105 amp-hour marine battery or larger is recommended and will provide approximately 7½ hours of continuous pumping time in a sump pump
installation with 8' (2.4 mm) of head pressure. In most installations the pump runs intermittently and the battery life is extended accordingly. Batteries
with top terminals are recommended for ease of installation. These batteries contain acid and proper precaution must be taken when handling to fit in
included battery box. Maximum battery size to fit inside battery box is 12½" (318 mm) Length x 7" (178 mm) Width x 9½" (241 mm) Height.
BATTERY SELECTION
1. Electrical wiring and protection must be in accordance with National
Electrical Code and any other applicable state and local electrical
requirements.
2. All installations require a basin cover to prevent debris from falling into
the basin and to prevent accidental injury.
3. Securely tape or clamp power cord to discharge pipe, clear of the float
mechanism(s).
4. Use a full-size discharge pipe.
5. Basin must be in accordance with applicable codes and specifications.
6. Pump must be level and float mechanism(s) clear of sides of basin
before starting pump. Float switch may be repositioned as needed.
7. Basin must be clean and free of debris after installation.
8. Gate valve or ball valve to be supplied by installer and installed
according to any and all codes.
9. Gas tight seals required to contain gases and odors.
10. Vent gases and odors to the atmosphere through vent pipe.
11. Install Zoeller Pump Stand (model 10-2421) under pump to
provide a settling basin.
RECOMMENDED INSTALLATION FOR ALL APPLICATIONS
EASY DO'S & DON'TS FOR INSTALLING A SUMP PUMP
1. DO read thoroughly all installation material provided with the system.
2. DO inspect system for any visible damage caused by shipping. Contact
dealer if system appears to be damaged.
3. DO clean all debris from the sump. Be sure that the pump will have a hard,
flat surface beneath it. DO NOT install on sand, gravel or dirt.
4. DO be sure that the sump is large enough to allow proper clearance for the
level control switch(es) to operate properly.
5. DO always disconnect pump from power source before handling.
DO always connect to a separately protected and properly grounded circuit.
DO NOT ever cut, splice, or damage power cord (Only splice in a watertight
junction box).
DO NOT carry or lift pump by its power cord.
DO NOT use an extension cord with a sump pump.
6. DO install a union in the discharge line.
DO NOT use a discharge pipe smaller than the pump discharge.
7. DO NOT use a sump pump as a trench or excavation pump, or for pumping
sewage, gasoline, or other hazardous liquids.
8. DO test system immediately after installation to be sure that the system is
working properly.
9. DO cover sump with an adequate sump cover.
10. DO review all applicable local and national codes and verify that the installation
conforms to each of them.
11. DO consult manufacturer for clarifications or questions.
12. DO inspect and test system for proper operations at least every three months.
The DC controller is equipped with a 10 amp charger for
maintaining the battery in a ready state and recharging
the battery after use when AC power is restored. Time for
recharge depends upon the amount of power consumed
by the pumping cycle during the AC power interruption.
The system may return to the charged LED position in a
very short period of time. A completely drained battery
may require up to 24 hours for full recharge.
