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" (51mm); see Figure 1.
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 Figure 1) 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" (9.5mm) bare wire exposed at the wire
end (see Figure 4).
8. Insert stripped wire end in small end of fuse holder
half; crimp holder onto wire and check crimp for
tightness (Figure 5).
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 6).
10. Remount block on band and cord clamp assembly on
pump.
11. Strip black switch wire back 3/8" (9.5mm) 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 clamps to positive battery
terminal.
B. White 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 7). If not, reverse wires to battery and recheck.
15. Replace screen.
16. Plug in charger to wall outlet.
17. Fill sump with water and check switch action. Adjust
tether if necessary.
DO NOT test run pump for more than 5
seconds without water in it. Running pump dry for
extended periods could damage pump and voids
warranty.
