Troubleshooting
Taste and/or Smell of Chlorine in Clean Water
Cause:
Concentration of chlorine in feed water is above the limit, which damaged the membrane. Pre-filter does
not work or does not remove chlorine from feed water.
Solution:
If the concentration of chlorine in feed water is above 2.0 ppm an additional pre-filtration stage should
be used. Replace the pre and post filters, membrane and flow restrictor.
Changed Smell and Taste of Clean Water
Cause:
Used post-filters. Used membrane. Storage tank contains unfiltered water.
Solution:
Replace the post-filter. If the smell and taste lingers, replace the membrane and flow restrictor. Disinfect
the whole system and storage tank.
Low System Capacity
Cause:
Pre-filters or membrane are clogged with sediments. Feed water does not comply with the standard
requirements.
Solution:
Replace the pre-filters. If the capacity does not improve, replace the post-filters, membrane and flow
restrictor. Increase water pressure, carry out additional filtration, etc. before doing the service.
Filtration Speed is Lower than Usual
Cause:
Water pressure in the storage tank is below 5-7 psi.
Solution:
Open the faucet valve and empty the tank completely. Check the pressure in the storage tank (keeping
the faucet valve open). If the pressure is low, increase it up to 0.4 bar (6 psi). Close the faucet in order to fill the
tank.
High TDS Value of Clean Water
Cause:
Feed water does not comply with the standard requirements. Used membrane.
Solution:
Increase water pressure, carry out additional filtration, etc. Replace the pre-filters, membrane and flow
restrictor.
Constant Water Flow to the Drain
Cause:
Shut-off valve is clogged.
Solution:
Clean or replace if necessary.
