Frequently Asked Questions - KDE5-18 KOSPEL
What electrical connections are needed for the KDE5-18 boiler?
The boiler requires a three-phase 400 V supply with an appropriately sized cable (minimum 6 mm²). It is essential to follow the diagram provided in the manual and to call a qualified electrician.
How to bleed air from the heating circuit?
Open the automatic air vent located at the top of the boiler during filling. If the vent is manual, use a key to release air until water flows out. Then check the pressure.
What to do if the boiler does not heat?
First check the power supply (circuit breaker, fuses). Then check that the room thermostat is calling for heat and that the set temperature is sufficient. If nothing works, the safety thermostat may have tripped: reset it manually.
What water pressure should the circuit have?
The cold pressure should be between 1 and 2 bar. If it drops below 1 bar, refill the circuit via the filling valve to the recommended value. Excessive pressure can damage the valve.
How to maintain the KDE5-18 boiler?
Annual maintenance by a professional is recommended to check safety devices, clean heat exchangers, and inspect the heating element. External cleaning should be done with a dry, non-abrasive cloth. Do not use chemical products.
The boiler makes an abnormal noise, what to do?
A whistling noise may indicate air in the circuit: bleed. A banging noise may come from a scaled heating element: descale or replace. If the noise persists, contact a technician.
What is the average lifespan of this boiler?
With regular maintenance, the lifespan can reach 15 to 20 years. Wearing parts like the heating element may need replacement after about 10 years. Follow the maintenance intervals.
Can I install the boiler myself?
The electrical and hydraulic installation must be carried out by a qualified professional in accordance with current standards. Incorrect installation can lead to safety risks and void the warranty.
Where to find spare parts for the KDE5-18?
Original Kospel parts are available from authorized dealers and online. Identify the part with the reference in the manual. Common parts such as thermostats and heating elements are easy to find.
What does the red light permanently on mean?
A fixed red light generally indicates a fault. Consult the manual for the corresponding error code. Possible causes include overheating or a sensor fault. Unplug the appliance and contact customer service.
