Make sure that the electrical plug connection is placed in a flood-proof area and is protected
from moisture.
Disconnect the mains plug before the maintenance work.
Avoid exposing the diesel pump to direct water ets or rain.
The user is responsible for the compliance with location specific safety and installing regula-
tions. (Ask an electrician).
Consequential damage arising from flooded rooms caused by dysfunctions of the appliance
must be avoided by means of the appropriate measures. (installing an alarm system, reserve
pump).
In case of malfunction the repair work can be carried out only by a qualified electrician or the
WilTec-service.
The appliance must not run dry or with a completely closed intake port. The manufacturer’s
guarantee is no longer valid if the damage is caused by dry running.
WARNING:
Read carefully all the safety guidelines and the instructions.
Non-compliance with the safety rules and regulations can lead to an electric shock, fire and/or serious
in ury. Keep the instructions and the safety guidelines in a safe place in case you need them in the fu-
ture.

Electrical connection
The electrical connection takes place by means of a safety socket 230 V ~ 50 Hz. Fuse protection
at least 10 Ampere.
The pump is turned on and off by means of a built-in ON-/OFF switch. The indicator lamp inside
the switch lights up if the engine is started.
The engine is protected against overloading or blocking by means of a built-in motor protection. In
case of overheating the pump is turned off automatically due to the overheat protection and after
its cooling, the pump is automatically started.
Suction pipeline
Connect a suction hose (plastic hose minimum 3/4"with spiral reinforcement) directly or with a
threaded fitting to the suction connection (intake connection) of the pump (1" Inside thread) of the
pump.
The suction hose that is used should have a suction valve. In case the suction valve cannot be
used, a check valve should be installed in the suction line.
Position the suction line on a rising gradient from the removal point towards the pump. Avoid lay-
ing the suction line over the pump height, air bubbles in the suction line delay and prevent the
suction process.
Suction and pressure line must be placed in such a way so that they exert no mechanical pres-
sure on the pump.
The suction valve should lie deeply enough in the medium to be pumped. This way the drop in the
fluid level prevents the pump from dry running.
A leaking suction line prevents the suction of the pumped medium by sucking in air.
Avoid sucking foreign particles (sand etc.).
Commissioning
Set up the pump on a fixed, flat place, where the temperature does not exceed 40°C. The pump
has to be placed in a horizontal position, so that the bearings can function properly, screw the
pump tight to its bottom part.
Bring the suction line ready for operation. The suction hose should not be narrower than the suc-
tion connection. If the suction lift exceeds 4 m, use a suction line with a larger diameter.
Elektrischen Connection herstellen.
Fill up the pump with the diesel or heating oil at the pressure port.
During the suction process the shut-off devices (pump nozzle and valve) in the pressure line must
be completely open, so that the air existing in the suction line can escape freely.
Depending on the suction lift and air volume in the suction line the first suction operation can take
approx. 0,5 min - 5 min. By longer suction times the medium to be pumped should be refilled.
If the pump is removed after being used, it has to be newly refilled before it is connected and op-
erated again.

Ventilation of the Diesel Pump:
The filler hole (1 - see picture below) of the diesel pump must be removed from the pump
housing. After that you fill in this filler hole the medium to be pumped, by
using a funnel. In this way the suction hose is fully filled. Filling the
pump is completed, when the pump body is fully filled as well. After this
the filler hole has to be closed and the pump should now convey (pump)
again.
Cleaning
The heating oil pump must be cleaned only by using mild cleaning agents as well as a damp cloth and
soapy water. Damage caused by inappropriate cleaning agents is not covered by warranty.
Maintenance
The pump is maintenance free. For a long operation life we recommend regular checking and ser-
vicing.
Attention!
Before every maintenance work the pump must be switched off, pull out the plug from the power
socket.
After long non-operation periods check if a proper turning of the rotor takes place.

Malfunctions of the pump
Engine does not run
Cause Corrections of malfunctions
No supply power (voltage) Check voltage
Pump impeller is blocked– thermo controller is deactiv-
ated
Dismantle the pump and clean it
The engine does not run Consult a professional electrician
Pump does not suck in
Cause Corrections of malfunctions
Suction valve is not in the pumped medium Bring the suction valve in the pumped medium
Pump room without pump medium Fill in pump medium in the suction nozzle
Air in the suction line Check if the suction line is well sealed
Saugventil undicht Clean the suction valve
Suction strainer(suction valve is blocked Clean the suction strainer
Max. suction lift is exceeded Check the suction lift
Insufficient flow rate
Cause Corrections of malfunctions
Suction lift too high Check the suction lift
Suction strainer is dirty Clean the suction strainer
The level of the pumped medium drops rapidly Place the suction valve more deeply
Pump capacity is reduced because of harmful
substances
Clean the pump and replace the wearing part
Thermo switch shuts down the pump
Cause Corrections of malfunctions
Engine overloaded – excessive friction
through foreign particles
Dismantle the pump and clean it,
prevent suction of foreign particles
(Filter)
Attention!
The pump must not run dry.
