OPERATING AND INSTALLATION INSTRUCTIONS LBE 250 / LBE 500
PAGE 30
Only mains water that corresponds with
the local mains water ordinance may
be used for the water supply. For the
connection to the water supply, only
the original connecting hoses provided
in delivery may be used. The operating
pressure of a minimum of 0.35 MPa
and a maximum of 0.7 MPa and a water
temperature of a minimum of 8 °C and a
maximum of 30 °C may not be undershot
or exceeded, respectively.
In case of a
chlorine content
over 0.1
mg/l, the standard water filter (5 μm)
must be replaced by a dual filter (5
μm/carbon) (optionally available as an
accessory). If the
iron content
of the
mains water exceeds a value of 0.1 mg/l,
an iron filter should also be built into
the water inlet pipe upstream of the fine
filter. The device can be used for a maxi-
mum hardness of water of 26 °dH.
When this value is exceeded, the ser-
vice life of the reverse osmosis memb-
rane is considerably reduced!
Water connection set (accessory), con-
sisting of:
• 1 waste water connection pipe
• 2 connecting hoses, 1.5 m each 3/4“
• 2 plastic screw connections 3/4“
• 1 wall mounting bracket
• 1 safety valve/water stop 3/4“
• 1 filter housing
• 1 water filter
• 1 item test strip for determining the
water hardness
In case of a defect (leakage),
the safety valve/water stop
closes and the uncontrolled di-
scharge of water is prevented. To re- es-
tablish proper function: close the water
valve, remove the hose, unscrew the sa-
fety valve/water stop, and press the red
button on the output side of the valve.
The heater battery (feed line and return
line) is to be connected to the heating
system via a circulation pump and a
three-way motor mixer valve. The feed
line temperature should amount to at
least 50°C and must be available cons-
tantly during the heating period.
Pump/mixer connection set (optional
accessory), consisting of:
• 1 circulation pump 230 V
• 2 screw connections, R 1/2a / 15 mm
(brass)
• 1 three-way mixer valve with actuator
230 V, Rp1/2“, DN 15, runtime 120 se-
