SYSTEM OPERATION TESTING
Testing Automatic Pump Operation
1.  The RLCSS Series automatic pumps are equipped with an integral 
float-operated mechanical switch. Automatic operation is 
achieved through the pump cord.
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/o 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
s
!
CAUTION Before working on the pump or switch, 
always unplug the pump power cord in addition to removing the fuse 
or shutting o 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 
aected 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.
