Thank you for purchasing this quality product. To minimize the risk of injury we urge that our clients take some basic safety precautions when using this device. Please read the operation instructions carefully and make sure you have understood its content. Keep these operation instructions safe.
Attention:
The device is not intended for use by persons (including children) with impaired or limited physical, sensory, and mental abilities or lack of experience and/or real knowledge unless they are supervised by a person responsible for their safety or you follow the instructions made by this person how to use the device correctly.
Children should be supervised to make sure that they do not play with the device.

Safety regulations

Run a visual inspection of the device before every use. Do not use the device if safety appliances are damaged or worn out. Never override safety regulations.
Use the device exclusively according to the intended purpose stated in the instructions for use.
You are responsible for the safety of the working environment.
If the cable or the plug is damaged due to external influences the cable must not be repaired! It must be replaced with a new one. This work can be carried out only by an electrician.
The voltage indicated on the type plate of the device of 230 V AC must correspond to the existent mains voltage.
Never lift, carry, or fix the device by using the power cable.
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 jets or rain.
The operator is responsible for compliance with location-specific safety and installation regulations. If necessary, ask a qualified electrician.
Consequential damage arising from flooded rooms caused by dysfunctions of the device must be avoided by means of appropriate measures (e.g., by installing an alarm system, a reserve pump).
In case of malfunction, the repair work can be carried out only by a qualified electrician.
The device 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 The manufacturer’s guarantee is no longer valid if the damage is caused by dry running.

Attention:
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 injury. Keep the instructions and the safety guidelines in a safe place in case you need them in the future.

Resistance

The temperature of the conveyed liquid should not exceed +35 ℃ in permanent operation.
The pump must not convey aggressive fluids (acids, alkali, etc.) or fluids with abrasive substances (sand). It must NOT pump water or easy flammable liquids (petrol).

Field of application
For conveying and transferring fuel oil (heating oil) or diesel fuel.

Electrical connection

The electrical connection takes place by means of a safety socket 230 V ~ 50 Hz. Fuse protection at least 10 A.
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 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 ¾″ with spiral reinforcement) directly or with a threaded fitting to the suction connection (intake connection) of the pump (1″ internal 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 laying the suction line over the pump height, air bubbles in the suction line delay and prevent the suction process.
The suction and pressure line must be placed in such a way so that they exert no mechanical pressure 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 (e.g., sand).

Commissioning

Set up the pump on a fixed, flat place, where the temperature does not exceed 40 ℃. The pump must 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 suction connection. If the suction lift exceeds 4 m, use a suction line with a larger diameter.
Plug the plug in an appropriate socket.
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 must be newly refilled before it is connected and operated again.

Ventilation of pump
The filler hole (part 1, see photograph below) of the diesel pump must be removed from the pump housing. After that, by using a funnel, fill the medium to be pumped into this filler hole. Thus, 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 must be closed and the pump should now convey (pump) again. wiltec 50588 Fuel Oil Pump and Diesel Pump -

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 a warranty.

Maintenance

Attention! Before every maintenance work, the pump must be switched off, pull out the plug from the power socket.

The pump is maintenance-free. However, for a long operation life, we recommend regular checking and servicing.
After long non-operation periods, check if the rotor turns properly.

Troubleshooting

The engine does not run

Causes	Solutions
No supply power (voltage).	Check voltage.
Pump impeller blocked – thermo controller has is deactivated pump	Disassemble

and clean pump.
Engine not running| Consult a professional electrician.

Pump does not suck in

Cause	Corrections of malfunctions
Suction valve not inside the pumped medium	Bring the suction valve in the

pumped medium.
Pump room without pump medium| Fill in pump medium in suction nozzle.
Air in suction line| Check if suction line is well sealed.
Suction valve untight| Clean suction valve.
Suction strainer/valve blocked| Clean suction strainer.
Max. suction lift exceeded| Check suction lift.

Insufficient flow rate

Cause	Corrections of malfunctions
Suction lift too high	Check suction lift.
Suction strainer is dirty	Clean suction strainer.
Level of pumped medium drops rapidly	Place suction valve more deeply.
Pump capacity reduced because of harmful sub-stances	Clean pump and replace

wearing parts.

Thermo switch shuts down pump

Cause	Corrections of malfunctions
Engine overloaded – excessive friction through foreign particles	Disassemble

and clean pump, prevent suction of foreign particles (filter).

Attention! The pump must not run dry.
