Operation / Maintenance
Airlocks
When a pump airlocks, it runs but does not move any
water. An airlock will cause the pump to overheat and fail.
The discharge pipe is plumbed with a predrilled anti-air-
lock hole. Leakage from the anti-airlock hole is normal
during pump operation.
Operational Check
Vertical Float Switch (CSS-3V Only)
1. Fill the sump with the correct amount of water to
check the operation and tightness of the connections.
During the first automatic cycle, it may take 30 sec-
onds or more before the pump is primed and pumping.
The pump will start as indicated in the "Pump, Motor,
Switch and Cord Specifications" table on Page 2.
2. Check the turn-off position. The pump will stop
approximately as indicated in the "Pump, Motor,
Switch and Cord Specifications" table on Page 2.
3. If the pump does not operate, check the electrical
service.
The vertical float has a short range of motion along a
vertical rod, which helps prevent the float from sticking.
Diaphragm Pressure Switch (CSS-3D Only)
1. Fill the basin with enough water to cover the pump.
Water pressure increases as the water level rises,
engaging the switch and turning on the pump.
2. The switch will turn the pump off when the water level
drops.
WARNING
Risk of electrical shock.
Can burn or kill.
Do not lift pump by
power cord.

CORD LIFT WARNING
This mechanism should never stick because the diaphragm
switch has no float. The switch is also not easily triggered
by water rushing into the basin, which helps extend the life
of the switch.

MAINTENANCE
Hazardous voltage. Can shock, burn, or kill.
Before removing the pump from the basin for service,
always disconnect electrical power to the pump and the
control switch. Do not lift the pump by the power cord.
See the "Cord Lift Warning" below.
NOTICE: To prevent clogging the pump, clear basin
of any debris if you remove the cover during or after
installation. Unplug the pump first.
NOTICE: The pump should only be serviced by trained
personnel. There are no consumer serviceable parts inside
the pump.
Disconnect the discharge and vent pipes from the unit,
remove the four basin cover bolts, and then lift the pump
out of the basin using the pump handles.
DO NOT attempt to open the pump further than removing
the base and bottom plate.
The pump motor housing contains a special lubricating oil
which should be kept clean and free of water at all times.
The sump basin and cover, pump, and piping should be
protected from freezing temperatures.
1. Attempting to lift or support pump by power
cord can damage cord and cord connections.
2. Cord may pull apart, exposing bare wires
with possibility of fire or electrical shock.
3. Lifting or supporting pump by power cord
Lift by
handle
will void warranty.
4. Use lifting ring on top of pump for all lifting/
lowering of pump. Disconnect power to
pump before doing any work on pump or
attempting to remove pump from sump.
