5 Installation
5.1 Safety instructions
5.2 Installation site requirements
– The air/water heat exchanger is to be mounted on an
enclosure and operated exclusively in accordance
with fig. 3 (vertical mounting, water connections at the
bottom).
– The ambient temperature must not 70°C.
– It must be possible to fit a condensate discharge (see
section 5.3.4 "Connecting the condensate water dis-
charge").
– It must be possible to fit a cooling water supply and re-
turn (see 5.4 "Connecting the water connection").
– The mains connection data as stated on the rating
plate of the unit must be guaranteed.
– The heat loss of the components installed in the enclo-
sure must not exceed the specific useful cooling out-
put of the air/water heat exchanger.
5.3 Assembly procedure
5.3.1 Assembly instructions
„
Check the packaging carefully for signs of damage.
Any packaging damage may be the cause of a subse-
quent functional failure.
– The enclosure must be sealed on all sides (IP 54). In-
creased condensation will occur if the enclosure is not
airtight.
– The air inlet and outlet must not be obstructed on the
inside of the enclosure.
„
When arranging the components inside the enclosure,
please ensure that the cold airflow from the air/water
heat exchanger is not directed at active components.
Fig. 3: Never direct the cold airflow at active components
„
Exercise particular caution with the airflow from the
blowers of built-in electronic components (fig. 3).
„
Never site the air/water heat exchanger directly adja-
cent to the mounting plate.
If such installation is unavoidable, appropriate meas-
ures must be taken to optimise the air routing.
„
It is important to ensure even air circulation inside the
enclosure.
Under no circumstances should air inlet and outlet
openings be obstructed, otherwise the cooling perfor-
mance of the unit will be reduced.
„
Ensure a suitable distance from electronic compo-
nents and other installed enclosures so that the re-
quired air circulation is not obstructed and prevented.

Warning!
Please note the maximum weights that
may be lifted by individuals. It may be
necessary to use lifting gear.
Work on electrical systems or equip-
ment may be performed only by an elec-
trician or by trained personnel under the
guidance and supervision of an electri-
cian. All work must be performed in ac-
cordance with electrical engineering
regulations.
The air/water heat exchanger may only
be connected after the aforementioned
personnel have read this information!
Use only insulated tools.
Follow the connection regulations of the
appropriate electrical power company.
The air/water heat exchanger must be
connected to the mains via an all-pin
disconnecting device to overvoltage
category III (IEC 61 058-1).
The air/water heat exchanger is not
deenergised until all of the voltage
sources have been disconnected!

Hygiene risk!
The unit must be installed such that, during
later operation, simple access to all surfaces,
the water connections and the condensate
drain of the air/water heat exchanger is en-
sured for the purposes of cleaning and main-
tenance.
