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 au-
tomatically resets aRer 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 dick-
ing sound as the breaker opens and resets.
NOTICE:
If the clicking
sound
continues
for more
than
30 minutes
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 goug-
ing, do not let battery
sit on concrete
floor. Install battery on
a shelf or protective
pad (plywood,
2x4s, etc.). Always
in-
stall 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 cor-
rosion.
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
swRch
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 ob-
struction.
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
be-
tween
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 4, for pump
capacity.
4. Check for low or defective
battery.
Pump
cydes
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
terminals.
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 Hgure 2) before
Ioos-
euing cord clamp.
6. Remove
cord
from
cord
clamp
and replace
with
new
" cord.
Make
sure
tether
length
is the same
as the 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 in-
stalling will mate with fuse holder
half on pump
wire.
9. Insert
fuse into
holder
and
snap halves
of housing
to-
gether
(Figure
7).
lO.Remount
Mock 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.
12.Bolt
black switch
wire onto battery
terminal clamp.
13. Reinstall
battery
clamps:
A. Black switch wire damps
to positive
battery terminal.
B. Black pump
wire clamps to negative
battery
terminal.
NOTICE: DO NOT reverse
terminal connections.
14.Turn pump upside down;
unclip and remove screen. Do
not remove
screw-mounted
bottom
plate. Lift switch to
momentarily
"bump"
pump. Check for correct operation
and
rotation
(pump
must
rotate
counter-clockwise
when
looking
at end of shaft - Figure 8). If not, reverse
wires
to battery
and recheck.
