MAINTENANCE
Regularly the user should perform a basic check to verify
if the appliance is functioning correctly, on the basis
of the following control points:
1. Check settings of electronic control panel.
2. Measure the contamination level before and behind
the appliance.
3. Check drain line from control valve; there
shouldn't be any water flow (unless appliance
is in regeneration).
4. Check drain line from cabinet overflow; there
shouldn't be any water flow.
5. Check appliance and surrounding area; there
shouldn't be any water leakages.
ROUTINE CHECKS
Occasionally it may be necessary to put the appliance
hydraulically in bypass, i.e. to isolate it from the water
distribution system; f.e.:
- in case of an urgent technical problem;
- when it is not necessary to supply treated
water to the house/application (refill
swimming pool, irrigation,...).
