Maintenance - Grundfos Sololift+ PWC-3 Montage- Und Betriebsanleitung

5. Maintenance

Sololift+ PWC-3 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.
Before starting work on the pump,
make sure that the fuse has been
removed, the plug has been pulled out
of the socket or the electricity supply
has been switched off. Make sure that
the electricity supply cannot be
accidentally switched on.
All rotating parts must have stopped
moving.
Any repairs to the motor and electric
components must only be performed
by trained service personnel.
Cleaning the Sololift+ PWC-3
Sololift+ PWC-3 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. Switch off the electricity supply.
2. Put detergent into the toilet bowl and flush.
3. Let the detergent work for approx. five minutes.
4. Switch on the electricity supply and flush.
5. Flush once again when the Sololift+ PWC-3 has
pumped.
Cleaning the toilet, cabinet shower and
washbasin
After cleaning the units connected, flush the toilet
once more with clean water.
Periods of non-use
If the Sololift+ PWC-3 is not going to be used for a
long period, it is recommended to flush twice with
clean water and turn off the water supply to all units
connected.
Frost protection
It is advisable to make the lifting station frost-proof if
there is a risk of frost, e.g. in a weekend cottage
during the winter. Empty the tank, see Periods of
non-use or add antifreeze.
