Model RBSU25 – Operating Instructions and Parts Manual
4. Test pump operation by filling the sump with water
while the main pump is unplugged. If the pump
operates properly, plug the transformer into the GFCI
protected outlet to begin charging the battery.
5. Protect electrical cord from sharp objects, hot surfaces,
oil and chemicals. Avoid kinking the cord and replace
damaged components immediately.
Operation
Always disconnect the power source
before attempting to install, service,
relocate or maintain the pump. nEVER touch
sump pump motor, water or discharge piping
when pump is connected to electrical power.
nEVER handle a pump or pump motor with
wet hands or when standing on wet or damp
surface or in water. Fatal electric shock CoULD occur.
Risk of electrical shock! Use
a GFCI receptacle to reduce
the risk of fatal electric shock. Cutting the cord
WILL void the warranty and make the pump
inoperable.
1. After installation, the back-up pump will start when
the water level rises above the depth that the primary
pump should start.
2. The control box has a DC charger designed to
shorten the recharging time of your battery, and to
prevent overcharging. In addition, the control box has
a time delay which keeps the pump from repeated,
short cycles when it shuts off. The time delay feature
will allow the pump to run 20-25 seconds after the
switch reaches the off position.
3. The control box contains multi-colored indicator
lights. When AC power is present, the lights will
indicate the charging state, and not reflect actual
battery voltage, particularly with a defective battery. In
order for the indicator light to provide an accurate
reading, steps "a" through "d" must be followed.
Unplug main AC pump and the
transformer. Risk of electrical shock!
a. After main pump and transformer are unplugged, a
power off alert tone will sound for 30 seconds.
b. Lift and release the float switch to activate the
back up pump.
c. When the pump stops, read the charge indicator
lights:
Green: Indicates the battery is fully charged.
Yellow: Indicates battery is partially charged, but
still operable.
Red: Battery is completely discharged or
defective
Red blinking: Battery discharged below level
where pumping can occur. Motor is locked out by
controller until battery is sufficiently charged to
run pump.
d. Plug in transformer and main AC pump.
4
When main AC power is out, and when pump has been
running, the lights will indicate battery status.
4. A chirping sound from the control box will accompany
the red light, indicating that the battery may require
attention or replacement. Voltage is only an indicator
of battery condition and may not reflect the true
condition of the battery. See maintenance for
instruction on assessing battery condition.
5. A single thirty (30) second tone will sound when
power to the system is interrupted and the power
failure light will illuminate. The unit will reset and the
light will go out automatically when power is
restored.
6. A three (3) second tone will sound every time the
pump starts.
Maintenance
install, service or relocate or perform any maintenance. If
the power source is out of sight, lock and tag in the open
(off) position to prevent unexpected power application.
Failure to do so CoULD result in fatal electric shock. only
qualified electricians should repair this unit. Improper
repair CoULD result in fatal electric shock.
follow steps listed below:
1. Unplug the transformer.
2. For batteries with top caps that can be removed,
the electrolyte level should be checked and
filled to manufacturer's specifications. The
charge for each cell should be checked with
a hydrometer. A gravity of 1.265 indicates
the battery is at full charge. If the specific
gravity of any of the cells varies more than
.050, the battery should be replaced.
NOTE: An inexpensive hydrometer can be purchased at an
automotive parts dealer.
3. Inspect the terminals and clamps for corrosion and
tightness. Clean and tighten as required.
4. Unplug the main pump and fill sump with water until
back-up pump turns on. Repeat process two times to
make sure pump is operating normally.
5. If pump operates normally, plug transformer into
wall outlet, turn on main pump. If pump fails to
operate normally, see Troubleshooting guide and
correct problem. Repeat step 5.
