4. CABINET INSTALLATION
4.1 Positioning
As the pumping station is IP20, it must be located in a roofed technical
room, protected from rain, splashing, direct sunlight and any source
of heat. The temperature/humidity sensors required to control the
humidifi er must not be aff ected by misting and they must be placed
away from direct sunlight and any heat source.
The cabinet must be installed in an environment with a temperature
between 5 and 40°C.
Around 1 m clearance must be left in front of the cabinet to allow the
door to be opened and maintenance to be performed. At the sides, a free
space of about 0.5 m (on both sides) must be provided, in order to allow
for the hydraulic connections on the right and the electrical connections
on the left.

4.1.1 Wall mounting
The cabinets can be wall-mounted or fl oor-standing.
In the event of wall mounting, it is recommended to use the metal frames
and screws supplied. See the distances shown in the following image for
drilling the holes and fastening the brackets.

4.1.2 Floor-standing installation
For fl oor-standing installation, the unit needs to rest on a raised platform
so as to allow connection of the drain hose, located on the bottom of the
cabine (see par. "Cabinet drain connection").

4.2 Water connections
WARNING: electric shock hazard.
Before making the electrical connections, the appliance must be
disconnected from the mains power supply and must be prevented
from being powered on. Electrical disconnection must be verifi ed by
measurement.
NOTE: observe the local regulations for connecting the system to the
drinking water supply (see VDI/DVGW 6023, DIN EN 1717 and DIN 1988-100).
4.2.1 Feedwater line
An expansion vessel should always be installed upstream of the cabinet,
so as attenuate variations in pressure in the feedwater line. It is also
suggested to install a mechanical fi lter on the feedwater line to the
cabinet (P/N ECKVESS050 for the fi lter vessel and P/N ECKFILT050 for the
fi lter cartridge). Finally, an on-off ball valve should be installed on the line
upstream of the cabinet, so as to allow for any maintenance operations
on the water circuit downstream.

Fig. 4.d
A hose with a minimum diameter Ø=1/2” should be connected upstream
of the cabinet so as to ensure the right fl ow-rate and pressure to the
humidifi er. The humidifi er inlet connection is 3/4” GAS F. The required
humidifi er inlet pressure is at least 3 bars.
NOTICE: for the Australian market and to comply with Watermark
requirements, a watermarked approved dual check valve shall be installed
in the supply line to the humidifi er when connected to potable water.
Should on the other hand the humidifi er be fed with treated water from a
Carel reverse osmosis system connected to potable water, the dual check
valve shall be installed in the supply line to the reverse osmosis system.
