Operation; Maintenance - DeWalt DXWP62383 Instruction Manual

ENGLISH

Operation

WARNING: The pump motor is thermally protected and
is not recommended for pumping liquids over 120° F (48.9°C).
The thermal overload protector will automatically shut down the
pump in an overheat situation. The motor will reset itself once it
cools down. This overload is designed as a safety device and it will
fail after repeated use. Normal operation is for fluids between 35°
F - 120° F (1.7°C - 48,9°C).
WARNING: Do not let the pump run dry. This pump relies
on water for lubrication and cooling. Operating the pump without
water may cause the motor to overheat or cause damage to seals
or internal parts. It may also shorten the life of your pump.
Automatic Operation:
1. Connect the piggy-back plug of the float switch into a
115 volt grounded GFCI receptacle. See Figure 2.
2. Connect the pump plug into the back of the piggy-back
float switch plug. See Figure 2.
3. Test your installation by filling the basin with water.
Observe the float switch through at least one complete
cycle to ensure it operates freely and does not contact
the sides of the basin. If necessary, adjust the float switch
or reposition the pump to ensure proper operation.
4. DeWalt sump pumps are equipped with an (A) anti-
airlock hole. A stream of water will emit from this hole
when the pump is operating. This is a normal feature
of this pump. The anti-airlock hole should be cleaned
periodically to prevent the pump from becoming air
locked. See Figure 3.

Manual Operation:
1. For manual operation or if the float switch has
malfunctioned, the pump can be operated manually by
bypassing the float switch. The pump power cord can be
disconnected from the piggy-back float switch plug and
connected directly to the receptacle. This will bypass the
float switch and the pump will run continuously. During
manual operation the pump should be monitored at
all times to ensure the pump does not run dry. When
pumping is complete disconnect from receptacle.

Maintenance

WARNING: Risk of electric shock. Always disconnect
the power supply before attempting to install, service or perform
maintenance on the pump.
WARNING: All repairs must be made by a qualified
technician.
CAUTION: This submersible pump contains oil which may
become pressurized and hot under normal operating conditions
– allow the pump to cool for 2-3 hours before servicing.
1. The pump motor is hermetically sealed in the housing
and does not require any service. Disassembly of the
motor housing or modification of the power cord voids
the warranty.
2. Periodically check the sump basin for accumulation of
mud, silt, sand and foreign objects. Clean the basin as
needed to prevent damage or clogging of the pump.
3. Periodically check the intake for obstructions. Clean if
necessary.
4. Periodically inspect and clean the anti-airlock hole.
5. Inspect the float switch for any accumulated sediment or
debris that may inhibit it from operating properly. Clean
if necessary.
6. Inspect the power cord for signs of damage or wear. Do
not operate the pump if the cord is damaged or worn.
7. In applications where the pump may not activate for
extended periods of time, it is recommended to cycle the
pump at least once per month to ensure the pumping
system is working properly when needed.
