Frequently Asked Questions - PPE4.B-15 KOSPEL

How do I install the Kospel PPE4.B-15 water heater?

Installation should be performed by a qualified technician. The heater must be wall-mounted using the provided brackets, connected to the water supply with a pressure relief valve, and wired to a 230V power source with appropriate circuit breaker.

What is the recommended temperature setting?

The recommended temperature is between 55°C and 60°C to prevent bacterial growth while avoiding scalding. Adjust via the thermostat knob.

How often should I descale the heater?

Descaling is recommended annually or more frequently in hard water areas. Use a descaling solution suitable for water heaters and follow the manual procedures.

What does the safety valve do?

The safety valve releases excess pressure to prevent tank rupture. It should be operated periodically to ensure it is not blocked.

Why is water not heating?

Possible causes: power failure, tripped circuit breaker, faulty thermostat, or damaged heating element. Check the power supply and reset the safety thermostat. If issue persists, contact a technician.

How do I replace the magnesium anode?

The magnesium anode protects the tank from corrosion. It should be checked every 2 years and replaced if worn. To replace: drain the tank, unscrew the old anode, install new one with sealing tape, and refill.

What is the maximum working pressure?

The maximum working pressure is typically 6 bar (600 kPa). Ensure your water supply pressure does not exceed this value.

Can I use an extension cord?

No, do not use an extension cord. The heater requires a dedicated circuit. Direct connection to a wall outlet or junction box is mandatory.
