3.3 Changing the strainer
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 heat-
er.
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 instantaneous water heater.
6. Purge the instantaneous water heater as described in the chapter
"Purging".
7. Switch the power supply back on again.
3.4 Purging
Each time it is emptied (for example after work on the plumbing system or following repair work on the appli-
ance), 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.
3.5 Cleaning and maintenance
• 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.
