12 VOLT DC BATTERY BACKUP PUMP

INSTALLATION INSTRUCTIONS

PREINSTALLATION CHECKLIST

1. Inspect your pump. Occasionally, products are damaged during shipment. If the unit or any of the parts are damaged, contact your dealer before using.

2. Read all the installation instructions regarding installing and start up. Retain for future reference.

SEE BELOW FOR
LIST OF WARNINGS

1. Testing for Ground. As a safety measure each electrical outlet should
be checked for ground using an Underwriters Laboratory listed circuit
analyzer, which will indicate if the power, neutral and ground wires are

correctly connected to your outlet. If they are not, call a qualied, licensed

electrician.

2. For your protection always disconnect the power supply from its power
source before handling the components of your DC backup pump or the
primary pump.

3. Installation and checking of electrical circuits and hardware should be

performed by a qualied, licensed electrician.

4. All electrical and safety codes must be followed in addition to the National
Electrical Code and all applicable local codes.

5. It is the owner’s responsibility to check the battery and battery

connection at least once a month. Batteries contain acid and
caution must be taken when handling.

6. Risk of electric shock - These pumps have not been investigated
for use in swimming pool areas.

7. According to the state of California (Prop 65), this product contains
chemicals known to the state of California to cause cancer and birth
defects or other reproductive harm.

CAUTION

1. Make sure there is a properly grounded 115V receptacle available. Do
not use primary pump circuit. The location must be within 6' of the control
box and battery. The power supply for your DC control system plugs
directly into the 115V outlet. DO NOT USE AN EXTENSION CORD.

2. Make sure the 115V electrical supply circuit is equipped with fuses or
circuit breakers of proper capacity.

3. DC emergency pumps are designed for handling clear water. Do not use

in septic tanks to pump efuent or sewage pits to pump sewage.

4. Repair and service of your DC backup system should be performed by
an authorized service station.

5. The installation of DC automatic backup pumps requires the use of a

variable level oat switch for operation. It is the responsibility of the
installing party, to ensure that the oat switch will not hang up on the

pump apparatus or pit peculiarities and is secured so the pump will turn
“on” and “off”. It is recommended that the pit be 18" in diameter or larger
to accommodate both a primary and a DC backup pump.

Turbulence caused by high velocity incoming water

can cause the DC pump to airlock. If this condition exists, the

incoming water must be bafed to avoid excessive turbulence.

MAINTENANCE

1. Inspect and test the system for proper operations at least every 3 months.*
(a) Red power on indicator light should be “on” indicating AC power is

on.
(b) Unplug primary pump and the control charger from power supply.
(c) Fill sump with water to the “on” level for the DC pump. Allow pump

to run a few minutes.
(d) The alarm will sound approximately 3 seconds after the pump starts

to run.
(e) Push alarm reset switch. The alarm will go “off”.

(f) Pump will shut off after water level is lowered and the oat drops

to the off position.

2. Plug the control charger and the primary pump into the wall outlet.
(a) The primary pump will come on and lower the water to the

normal operating level and shut off.
(b) The “yellow” charging light should be on. The charger is replacing

the energy consumed during the test. The “green” light will come on
after the charger has replaced the energy consumed during the test.

*Wet cell batteries should be checked every month.

TROUBLESHOOTING INFORMATION

1. DC Pump won’t run.
(a) Check 30 amp fuse in line from pump to switch (see g. 3). If fuse

is blown, replace with 30 amp Littelfuse type 3AG, series 311.
(b) Check for proper connections.
(c) Check all wire terminal points. Clean if required.
(d) Check for low battery. Service battery if required.

2. Pump runs but pumps very little or no water.
(a) Check for low battery. Battery will recharge if Red power “on”

light indicates power has been restored and the oat switch is

in the off position.
(b) If immediate usage is required, remove and replace dead

battery with a full recharged battery.
(c) Due to varying conditions the pump may continue to run on a

low battery without sufcient power to remove water. Pump will

not stop running until battery is completely discharged.
(d)

not store sufcient energy for full service. A weak recharged

battery can only be detected by reduced pumping time or by

professional load testing equipment. If your emergency pump

system is used frequently the battery should be checked by a

qualied battery dealer.

3. Pump cycles too frequently.

(a) Check positions of rubber stops on oat rod.
(b) Adjust upper rubber oat stop as required. Recommended for

standard installation.

Weak batteries can be recharged but may

4. Float switch in “on” position. Pump won’t run.
(a) Remove pump. Check for obstruction in pump preventing

impeller from rotating.

5. Pump runs, but pumps water intermittently.

(a) Pump is air locking. Check ow of water incoming to sump. If

water is entering the sump at a high velocity creating a turbulent
condition, a mixture of air and water may cause a complete

or partial air lock and reduce or stop the ow of water in the

discharge pipe.

(b) Bafe the incoming stream of water to reduce turbulence.

Diverting water stream against wall of basin usually corrects an
air lock problem.

6. Water level stays high. DC Pump continues to run.
(a) Battery is low.
(b) If power has been restored and water in sump remains high check

primary pump. Service if required.

(c) After several hours the battery will be restored to full charge.

7. Alarm sounds during battery recharge cycle.
(a) To silence alarm if alarm will not reset, unplug the charger from

115V wall outlet, then disconnect the black lead from charger on
negative (-) battery post. Check battery. Replace if necessary.
Reconnect and refer to Installation (step 12).

Gal. per min.

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 pump may go
back to the ready run position in a very short period of time. A completely
drained battery may require up to 24 hours for full recharge. If battery does
not charge properly, the LCD will display BATFAIL and alarm will sound.

BATTERY SELECTION

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 6 hours of continuous pumping time in a sump pump installation
with 8' 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. "Wet" cell batteries contain acid and
proper precaution must be taken when handling. Maximum battery size 13½"
Length x 7" Width x 9½" Height.
