4.1 Cleaning the Sololift2
The Sololift2 is normally kept clean through regular flushing of the
toilet.
If the Sololift2 is rarely used, we recommend occasional internal
cleaning which is performed as follows:
1. Disconnect the power supply.
2. Put detergent into the toilet bowl, cabinet shower or
washbasin. Flush the toilet or turn on the water.
3. Let the detergent work for approximately 5 minutes.
4. Switch on the power supply, and flush the toilet with clean
water, or turn on the water.
5. Flush the toilet with clean water, or turn on the water again
until the Sololift2 has pumped.
4.2 Cleaning the units connected
After cleaning the units connected, flush the toilet once more with
clean water, or turn on the water until the Sololift2 has pumped.
4.3 Periods of inactivity
If the Sololift2 is not to be used for a long period, we recommend
that you flush the toilet twice with clean water, or turn on the
water until the Sololift2 has pumped twice. Then disconnect the
water supply to all units connected.
If there is a risk of frost, drain the tank of water.
