cuit in main power panel “Backup sump pump power supply; do
not turn off”.
3. With charger properly connected and plugged in, the panel on
the front of the charger will appear as in one of the following:
A.
If battery is dead, charger will supply about 10 amps power
(see Figure 4A).
B.
If battery is near full charge, charger will deliver about 5
amps power (see Figure 4B).
C. If battery is fully charged, charging current will be 0 amps
and green LED lamp will be lighted (see Figure 4C).
4. The charger is equipped with a self-resetting circuit breaker
which protects it from temporary overloads. In case of an over-
load, the circuit breaker will open. It automatically resets after a
short cool-down period. In some conditions where the overload
is extended the breaker will
cycle, repeating the open/reset
process indefinitely. When this happens, normally the charger
will emit a clicking sound as the breaker opens and resets.
NOTICE: If the clicking sound continues for more than 30 min-
utes or so, check for reversed charger connections to the battery
and for shorted cells in the battery.
BATTERY MAINTENANCE
NOTICE: To protect battery case from chipping and gouging, do
not let battery sit on concrete floor. Install battery on a shelf or pro-
tective pad (plywood, 2x4s, etc.). Always install battery in a dry loca-
tion that is protected from flooding.
Every three months, check battery as follows to maintain battery in
best condition:
1. Unplug battery charger.
2. On batteries with removable top caps, measure specific gravity
of the electrolyte. Use a hydrometer (available at auto parts
stores). If the specific gravity of any cell is less than 1.225 or if
there is more than .050 variation between cells, replace the bat-
tery.
3. Check electrolyte level and refill as needed.
4. Check battery terminals and clamps for tightness and corrosion.
Clean and tighten as needed.
5. Plug in battery charger.
TROUBLESHOOTING
Pump won’t run.
1. Check all connections.
2. Check for low or defective battery.
3. Check that automatic switch is free to swing up and down.
4. Blown fuse in switch circuit. Unplug fuse holder in positive wire
to pump and check to see if impeller is free to turn. If impeller is
locked, remove the housing around the impeller and remove the
obstruction. Reassemble pump and reconnect. Replace fuse.
Motor hums but pump won’t run:
1. Check for low or defective battery.
Pump runs but pumps very little or no water:
1. Make sure a check valve is installed and functioning between
primary pump discharge and Backup Sump Pump tee.
2. Check for obstruction in discharge pipe.
3. Discharge pipe length and/or height exceeds capacity of pump.
See Table I, Page 2, for pump capacity.
4. Check for low or defective battery.
5. Positive (+) and negative (–) wires are reversed.
Pump cycles too frequently:
1. Tether length too short on automatic float switch. Make sure that
tether is at least 2" (51mm); see Figure 1.
2. Main check valve located between discharge of primary pump
and the Backup Sump Pump tee is not installed or is not working
properly. Install or repair as required.
Charging needle jumps to “CHARGING” and drops back
quickly:
1. This is normal and becomes less frequent over time.
