Installation and Operating Instructions
KWL Hygrobox KWL HB.. EH/WW
Device setup - installation
The device may only be installed in
frost-free, dry rooms. The room tempe-
rature must lie between +5 °C and max.
+40 °C.
Ventilation system air ducts, which are
not installed in heated areas, must be
designed with suitable heat insulation
(risk of temperature falling below the
dew point temperature), to prevent the
formation of condensation.
For components e.g. windows with heat
insulation properties or faulty structural
design, and in old buildings, condensa-
tion may form e.g. on window glass at
cold temperatures and in case of incre-
ased air humidity in living areas. The
surface temperature of the components
must lie above the dew point tempera-
ture of the indoor air (minimum approx.
+15 °C).
In normal operation, germs or mould
cannot form inside the device unit since
the humidification water is continuously
treated and disinfected during operation.
Mounting
The device is intended for horizontal
mounting. It may deviate a maximum of
+/-1° from the horizontal position and
must be mounted to a massive wall that
can bear the load. The intrinsic opera-
ting weight of the air humidification unit
must be taken into consideration for the
suspension. Shocks or jolts must not
affect the device. The national and local
regulations must be observed for moun-
ting and setup. The device may only be
installed in compliance with the national
installation regulations.
Electrical connection
The electrical connection of the
supply and sensor line should
be performed by an electrician accor-
ding to the local regulations. Before the
device is opened, the voltage supply
must be shut off at all poles and secu-
red against reactivation. If the mains
connecting line of the device is dama-
ged or defective, it must be repaired or
replaced immediately to prevent risks.

This work may only be performed by
authorised specialist personnel.
Water connections
The water, heating and waste water
connections must be established by
an expert. Only the original connecting
hoses provided in delivery may be used
for the connection to the water supply.
Pay attention to the seal tightness of the
lines. The maximum water pressure of
the drinking water connection of 0.7 MPa
and of the water heater battery of 1 MPa
may not be exceeded.
Water quality
Only drinking water that corresponds
with the drinking water ordinance may
be used for the water supply. The water
inlet pipe to the air humidification unit
should be established using optionally
available connection sets.
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). If the iron content of the drin-
king water exceeds a value of 0.1 mg/l,
an iron filter should also be built into the
water inlet pipe.
The device 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.
Operation of the device
Any operation that impairs the safety
of the device is prohibited. All warning
and safety devices should be regularly
checked for proper functioning. Safety
devices must not be disassembled or
decommissioned.
Installation, disassembly, maintenance
and servicing of the device
If maintenance work or repairs are
performed, the device should be isolated
from the power supply. The attachment
or installation of additional equipment
is not permitted. In this case, please
consult with the manufacturer.
