The cold water connection of the instantaneous water heater is equipped with a strainer. Dirt
deposited in this strainer can reduce the hot water output. Clean or replace as follows.
1. Switch off the power supply to the instantaneous
water heater.
2. Close the shut-off valve in the inlet pipe.
3. Disconnect the water pipe from the water inlet. The
water inlet is indicated in blue on the rating plate
(under the cover). This can cause water leakage.
4. Lever the strainer out of the connection piece of the
instantaneous water heater and clean or replace it.
5. Insert the clean strainer into the connection piece and
connect the water pipe to the water inlet of the instan-
taneous water heater.
6. Purge the instantaneous water heater as described in
the chapter “Purging”.
7. Switch the power supply back on again.
Fig. 12: “Changing the strainer”
Each time it is emptied (for example after work on the plumbing system or following repair
work on the appliance), the instantaneous water heater must be purged before it is used
again.
1. Switch off the power supply to the instantaneous water heater.
2. To purge the instantaneous water heater, open the hot water tap and wait until the water
emerges free of air bubbles.
3. Switch the power supply back on again.
• Plastic surfaces and fittings should only be wiped with a damp cloth. Do not use abrasive or
chlorine-based cleaning agents or solvents.
• For a good water supply, the outlet fittings (e.g. jet regulators and shower heads) should be
unscrewed and cleaned at regular intervals. Every three years, the electrical and plumbing
components should be inspected by an authorised professional in order to ensure proper
functioning and operational safety at all times.
