Technical Data

WRO 300 H
Water Supply
Input Min. 3.0 l/min required
Feed Water Pressure During operation — there is an inlet
flow of water into the WRO unit.
0.15 to 0.3 MPa (22 to 45 PSI)
Maximum design pressure:
0.8 MPa (115 PSI)
If the feed water pressure exceeds 0.3
MPa (45 PSI), a flow regulator, order
number WTW522001001, should be
installed.
Feed Water Tempera-
ture
+5 to +30 °C
Feed Water Quality Potable water should be used.
Particle filtration shall be used (< 5m)
Carbon filtration shall be used if water
is chlorinated, see limits below.
Membrane life expectancy might be
reduced if the unit is operated outside
of the following limits. For example,
additional maintenance such as clean-
ing to remove scale from hard water
buildup may be required if the hard-
ness level is exceeded.
Hardness <0.3 °dH (6 ppm as CaCO
3
)
Iron <0.1 mg/l
Manganese <0.1 mg/l
Turbidity <1 JTU
Total dissolved salts
(TDS)
<1500 mg/l
Fouling index (silt den-
sity index)
<5
Chlorine (total) <0.1 mg/l
Drain
Drain output flow dur-
ing RUN mode
1.2 ±0.1 l/min
Height difference
between the drain hose
outlet and the WRO
300 H drain outlet.
Maximum 1.0 m
Drain (length of hose) Maximum 5 m
Drain flow capacity Minimum 3.0 l/min required
Max temperature 85 °C
