6. REGULAR MAINTENANCE RECORDING FORM
Model: WTS Compact Serial number Date of fi rst start-up
Regular maintenance recording form
(to be fi lled in with a monthly interval)
Values to be measured on the spot
Conductivity at the inlet Conductivity at the outlet
Pump working pressure
(default from 5 to 10 bar)
Decay quantity Drain quantity
Recovery value
permeate / (pdrain) = about 40-60%
Expansion vessel
Stop pressure (default ≅ 4 bar) Air precharge pressure (default ≅ 1.8 bar)
To measure the precharge pressure, it is
advisable to drain the vessel and use a pressure
gauge to measure the air residual pressure
in the same vessel. It is advisable to perform
this operation every month, to guarantee the
hygiene of the stored water.
Start pressure (default
≅
2 bar)
Spare parts

fi lter
If pressure drop > 1 bar
IMMEDIATELY REPLACE THE FILTER or REPLACE EVERY YEAR
Date of last fi lter replacement:
Micrometric fi lter
Quantity of free chlo-
rine in the feed water
If < 0.1 replace 3 months
0.1< If < 0.2 replace 2 months
Date of last fi lter replacement:
Osmotic membrane
Replacement recommended when the conductivity value
of the permeate or the permeate fl ow rate value is not
satisfactory any more
Regular replacement recommended once every two years.
Date of last membrane replacement:
UV light
(optional)
The UV light should be replaced every 10000 hours of opera-
tion (about once a year).
Date of last UV light replacement:
The removal and cleaning of quartz is recommended ap-
proximately every 6 months
