CONNECTION
KWL Hygrobox KWL HB.. EH/WW
Only drinking water that corresponds
with the drinking water ordinance may
be used for the water supply. Only the
original connecting hoses provided in
delivery may be used for the connec-
tion to the water supply. 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.
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 ac-
cessory). If the iron content of the 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 de-
vice can be used for a maximum water
hardness of 26°dH.
If this value is exceeded, the service life
of the reverse osmosis membrane is
considerably reduced!
Water connection set (Accessories)
consisting of:
The heater battery (supply line and
return line) is to be connected to the
heating system via a circulation pump
and a 3-way motor mixer valve. The
supply line temperature should amount
to at least 50°C and must be available
constantly during the heating period.
Pumps/mixer connection set (optional
accessories) consisting of:
• 1 pc circulation pump 230 V
• 2 pcs screws, R 1/2a / 15 mm MS
(brass)
• 1 pc 3-way-mixer valve with actuator
230 V, Rp1/2", DN 15, run time 120 se-

• 1 pc waste water connection pipe
• 2 pcs connection hoses a.1.5 m 3/4"
• 2 pcs plastic screw connections 3/4"
• 1 pc wall mounting bracket
• 1 pc safety valve 3/4"
• 1 pc filter casing
• 1 pc water filter
• 1 pc test strip to determine the water
hardness
In case of a defect (leakage), the safe-
ty valve 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, and press the red button
on the output side of the valve.
NOTE: In case of connection to the drin-
king water network, the use of a system
separator is recommended.
