Mounting
The unit is intended for horizontal mounting. It must be mounted on a massive, load-bearing wall with a maximum permissible
deviation of +/- 1° from the horizontal position. The net operating weight of the humidification unit must be taken into consideration
for the suspension. It must be restored immediately to prevent hazards. These worksteps must only be performed by authorised
qualified professionals.
Water connections
The water, heating and sewage connections must be established by specialist personnel. For connection to the water supply, only the
original connection tubes supplied may be used. Ensure that the pipes are tight. The maximum water pressure of the drinking water
connection of 0.7 MPa and the water heater battery of 1 MPa must not be exceeded. The installation of a water stop valve is mandatory.
Water quality
Only drinking water complying with the Drinking Water Ordinance may be used for the water supply. The connection to the drinking
water pipeline is to be established using the connection set supplied. With a chlorine content of more than 0.1 mg/l, the standard wa-
ter filter (5 μm) must be replaced by a dual filter (5 μm / carbon). If the iron content of the drinking water exceeds a value of 0.1 mg/l,
an additional iron filter must be mounted in the water supply line.
The unit can be utilised for a maximum water hardness up to 26 °dH (German hardness). When this value is exceeded, the durability
of the osmosis membrane is significantly reduced.
Operation of the unit
Any work practices that could potentially impair the safety of the unit are prohibited. All warning and protective devices must be
checked for proper functioning at regular intervals. Safety devices must not be dismounted or deactivated.
Mounting, dismounting, maintenance and repair of the unit
If maintenance work or repairs are carried out, the unit must be switched to a de-energised, zero-potential state. No additional equip-
ment must be added on or installed. In this case, consult the manufacturer.
Electrical / electronic systems
Work on electrical system parts may only be carried out by persons trained in electrical engineering. If maintenance work or
repairs are carried out, the unit must be switched to a de-energised, zero-potential state. If faults occur in the electric power
supply, switch off the unit immediately. Only use original fuses with the specified amperage. The electrical equipment of the unit must
be checked at regular intervals. Identified defects such as loose connections or scorched wires must be removed immediately. After
carrying out electrical work or repairs, the protective measures must be tested (e.g. earthing resistor).
Requirements with regard to the place of installation
The air humidification unit may only be installed in rooms where a water drain is available. Furthermore, safety precautions must be
provided for in the room, safely and automatically shutting off the water supply to the air humidification unit in the event of a leakage
(water stop valve). The air humidification unit is designed with the IP20 degree of protection.
