Water drain
The drain connection has an outside diameter of 22.1 mm. A plastic hose can be connected to the drain connection
which can be routed out of the unit by means of the openings in the unit provided for this purpose.
When creating the drain, attention is to be paid to provision for cleaning.
As the water drain is depressurized, we recommend routing the drain hose passing through a syphon, as described in
the unit operating instructions under "syphon installation", into an open collector funnel to ensure free discharge.
The drainage pipe should be routed to the sewerage system with sufficient gradient (at least 5%) and should be located
approx. 30 cm below the humidifier. Attention is to be paid to temperature resistance when plastic pipes are used. If
copper pipe is used, it must be earthed. For the drainage pipe an inside diameter of at least 22 mm is required.
12.1.2 Supply connections
The steam humidifier is installed and electrically connected in the A/C unit. The local regulations of the water supply
company are to be complied with when making the hydraulic connection.
We recommend the installation of an Aqua-stop valve in the water supply of the humidifier. In ad
-
dition to this, the room, in which the A/C unit with the humidifier is installed, should be equipped
with a water detection system.
Water supply
The water connection is made from the cold water mains and is to be equipped with a shut-off valve. It is recom-
mended to install a filter to retain solid particles of pollution. The humidifier can be connected directly to the mains
by a threaded tenon of 3/4" when the water pressure is between 1 and 10 bar. The pipe should have a diameter of
at least 6 mm. In the factory a 680 mm hose with 3/4 inch nut on each side is mounted to simplify the connection to
the piping on site.
If the line pressure is more than 10 bar, the connection must be made via a pressure reducing valve (set to 4-6 bar).
In each case it is to be ensured that the manufactured water pipe upstream of the connection to the humidifier is
flushed properly. We recommend only using copper pipes. The water supply temperature must not exceed 40°C.

As the water drain is depressurized, we recommend routing the drain hose first into an open collector funnel and
then passing through a syphon to the drainage system to ensure free discharge.
