Each type of water segregates and deposits incrustations and lime when high temperatures are given.
These deposit in the heating unit and have a negative impact on functioning and product life.
the reason why an antiliming unit should be placed before the circuit starts in case of hard water
conditions.
Therefore it is indispensable to decalcify the heating unit and heating element
from time to time.
Maintenance:
- Never use heating unit without water!
- Heating Unit has to bleed regularly once per month.
! Attention: hot water may escape!
- Heating unit has to be thoroughly cleaned and decalcified at least twice per year
If required several times per year : frequency depends on local water hardness and quality,
Proceedure:
1) Remove lime carefully from heating unit.
For cleaning purposes the heating unit has to be separated from mains current!
Put operating switch on "off"
Turn off water flow.
Drain water line (pos. 10) completely.
Remove pump.
2) Screw in plugs 1¼" (not delivered, on site).
3) Take out ventilation screw.
4) Fill in approx. 0,5 l of cleaner or decalcifier respectively, e.g. vinegar essence.
5) Let it sink in and work.
-> Residence time depends on type of cleaner and level of fouling.
6) Unscrew Closing Plug, collect cleaner and clean it up environmentally acceptable.
In case of tough dirt (minerals/rust/lime) clean heating tube with bottle brush.
Drain and scour heating unit with clear water.
7) Assemble the parts in reverse order.
Start-up of heating unit (see first start-up).
