Inlet tap water treatment recommendations (optional)
Water filtration to eliminate solid particles:
To avoid any trouble or leakage due to solid particles obstructing the inlet water valve we recommend the
use of water pre-filter.
Water filtration to eliminate microorganisms:
To reduce the inlet tap water microorganism quantity we recommend to use a water filter of 20 μm followed
by a water filter of 1 μm mesh size.
To prevent any biofilm contamination, we recommend the installation of a ceramic water filter of 0.5 μm mesh
size with silver ions.
To reduce the water microorganisms quantity after the last filtration, we recommend purging regularly the
inlet water circuit.
Microfiltration (0.5 μm)
to eliminate pathogenic or-
ganisms (bacteria, parasites,
cysts...)
Silver ions to avoid any internal
microbiological growth
45 l/min at 4 bar water pres-
sure.
Operative pressure: between 1
and 9 bar
Connections: 1” FF
Microfiltration (20
μm) to eliminate solid
particles.
Connections: 3/4” FF
Microfiltration (1 μm)
to eliminate solid
particles and bacte-
ria.
Connections: 3/4” FF
NOTES
- Water filters (cartridges and ancillaries) must comply with potable water standards applicable in your country
(example : KTW/W270, DVGW, ACS, NSF, etc.).
UV lamp water treatment utilisation is subject to the following rules:
- As UV lamp water treatment can increase the water temperature, we recommend to use this system with
a loop water system installation or with controlled inlet water purge (in order to maintain water temperature
below 20°C).
- UV lamp water treatment must be installed with minimum two water filtration stages (20 μm and 1 μm) to avoid
any shadow effect.
