SYSTEM OPERATION TESTING

Testing Automatic Pump Operation
1. The LG-SS100V automatic pump includes a remote vertical
switch with a piggyback plug on the switch cord. The pump
must be plugged into the piggyback plug on the switch cord for
automatic operation.
2. When these pumps are installed in a basin with a sealed cover,
switch operation cannot be observed. The basin cover will
usually have a spare hole that is plugged with a rubber plug.
This plug can be removed and switch operation can be observed.
3. Plug the power cord into a grounded receptacle with voltage
consistent with the pump voltage, as indicated on the pump
nameplate.
4. Be sure the gate valve in the discharge line is open.
5. Run water into the basin until the pump is activated.
a. Do not attempt to run the pump without water;
this could result in permanent damage to the pump.
6. Confirm that the pump and its control switch are functioning
as intended.
7. Confirm that the ON/OFF levels are within specification, and
confirm that no potential obstructions exist that could inhibit
switch operation.
8. Confirm that there are no leaks in the pump discharge plumbing
and main home drain pipe plumbing.
a. It is normal for a stream of water to spray from the air
bleed hole in the pump's plumbing. Confirm that this
spray is captured within the basin.
9. Allow the pump to operate through several on/off cycles.
If the pump does not operate properly, consult the "Troubleshooting"
table. If the solution still cannot be found, please contact the place of
purchase. They will assist you in replacement or repair, if required.
Do not let the unit run dry (without liquid). It is designed to be cooled
by pumping fluid. The seal may be damaged and the motor may fail if
the pump is allowed to run dry.
If the unit is going to be idle for a period of time, follow the cleaning
instructions outlined in the next section. Do not let the unit freeze.
This may cause cracking or distortion that may destroy the unit.

MAINTENANCE

CAUTION
!
switch, always unplug the pump power cord in addition to removing
the fuse or shutting off the circuit breaker.
This unit is permanently lubricated. Oiling is not required.
Do not, in any case, open the sealed portion of the unit or remove
housing screws.
s
NOTICE
!
Inspect and test the pump system
condition and operation every 3 months (more frequently in heavy-
use applications).
1. LET PUMP COOL FOR A MINIMUM OF 2 HOURS BEFORE ATTEMPTING
TO SERVICE.
a. Submersible pumps contain oil that becomes pressurized
and hot under normal operating conditions.
2. Check the power cords and electrical outlet for damage
or corrosion.
a. The power cord on these units cannot be replaced.
In case of damage, the whole unit must be replaced.
3. Check the pump system components (basin, pump, switch, etc.)
for any build-up (sludge, sediment, minerals, etc.) that would
inhibit functionality of the components.
a. If significant, remove build-up or replace
affected components.
4. Confirm that all flexible coupling hose clamps are fully engaged
with plumbing and fully tightened.
5. Test the operation of the pump system by following the
instructions in the "System Operation Testing" section
of this manual.
6. While the pump is running, make sure a stream of water is
escaping from the air bleed hole.
a. If not, clear the hole of any deposits or debris.
