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 overload, 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 minutes or so, check for reversed charger con-
nections 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 protective pad (plywood, 2x4s, etc.).
Always install battery in a dry location 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 battery.
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 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 3, for pump capacity.
4. Check for low or defective battery.
Pump cycles too frequently:
1. Tether length too short on automatic float switch. Make
sure that tether is at least 2"; see Figure 2.
2. Main check valve located between discharge of primary
pump and the Backup Sump Pump tee or check valve
not installed or working properly. Install or repair as
required.
SWITCH REPLACEMENT
1. Unplug battery charger from wall outlet.
2. Disconnect both battery clamps from battery ter-
minals.
3. Unbolt black switch wire from battery clamp.
4. Unplug fuse holder in white wire; save fuse.
5. Make a note of tether length (see Figure 2) before
loosening cord clamp.
6. Remove cord clamp assembly (Key No. 3, Page 7)
from pump and slide mounting block off of steel band.
Loosen screw in block and pull switch cord out of
clamp. Pull new switch cord through clamp and
tighten screw. Make sure tether length is the same as
old switch’s tether.
7. Strip insulation off of white wire on new switch,
leaving 3/8" bare wire exposed at the wire end (see
Figure 5).
8. Insert stripped wire end in small end of fuse holder
half; crimp holder onto wire and check crimp for
tightness (Figure 6).
NOTICE: Be sure that fuse holder half which you are
installing will mate with fuse holder half on pump
wire.
9. Insert fuse into holder and snap halves of housing
together (Figure 7).
10. Remount block on band and cord clamp assembly on
pump.
11. Strip black switch wire back 3/8" from end of wire.
Crimp wire terminal onto end of wire and check for
tightness.
