WL600A is practically maintenance-free. However, regular use and cleaning will ensure faultless operation and a long operating life.

To prevent unnecessary pumping, it should be checked that the toilet cistern and possible water taps are tight.

WL600A is normally kept clean through regular flushing of the toilet.

For systems which are used rarely, occasional internal cleaning is recommended which is performed as follows:

1. Unplug the unit or switch off the power source.

2. Put detergent into the toilet bowl and flush.

3. Let the detergent work for approximately five minutes.

4. Plug in the unit or switch on the electricity supply and flush the toilet.

5. When WL600A has finished pumping ,flush once again .
