Warnung!

Bitte beachten Sie die maximal zulässi-
gen Hebegewichte für Personen. Ggf. 
ist eine Hebevorrichtung zu verwenden.
Arbeiten an elektrischen Anlagen oder 
Betriebsmitteln dürfen nur von einer 
Elektrofachkraft oder von unterwiese-
nem Personal unter Leitung und Auf-
sicht einer Elektrofachkraft den 
elektrotechnischen Regeln entspre-
chend vorgenommen werden.
Der Luft/Wasser-Wärmetauscher darf 
erst nach Lesen dieser Informationen 
von den o. g. Personen angeschlossen 
werden!
Es darf nur spannungsisoliertes Werk-
zeug benutzt werden.
Die Anschlussvorschriften des zuständi-
gen Stromversorgungsunternehmens 
sind zu beachten.
Der Luft/Wasser-Wärmetauscher muss 
über eine allpolige Trennvorrichtung 
nach Überspannungskategorie III (IEC 
61 058-1) an das Netz angeschlossen 
werden.

Der Luft/Wasser-Wärmetauscher ist 
erst nach Trennung von allen Span-
nungsquellen spannungsfrei!
Schalten Sie den Luft/Wasser-Wärme-
tauscher vor dem Öffnen der Elektro-
Anschlussbox und vor Arbeiten am 
Wasserkreislauf spannungsfrei und si-
chern Sie ihn gegen versehentliches 
Wiedereinschalten.
Die Spannungszuschaltung darf erst er-
folgen, wenn das Abdeckblech der 
Elektro-Anschlussbox ordnungsgemäß 
verschraubt ist.

Vorsicht!

Verwenden Sie niemals brennbare Flüs-
sigkeiten zur Reinigung des Luft/Was-
ser-Wärmetauschers.
An nicht vollständig entgrateten Boh-
rungen und Ausschnitten besteht 
Schnittgefahr, insbesondere bei der 
Montage des Luft/Wasser-Wärmetau-
schers.

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 only be carried out by an 
electrician or by trained personnel under 
the guidance and supervision of an 
electrician. All work must be carried out 
in accordance with electrical engineer-
ing regulations.
The air/water heat exchanger may only 
be connected after the above-men-
tioned personnel have read this informa-
tion!
Use only insulated tools.
Follow the connection regulations of the 
appropriate electrical supply company.
The air/water heat exchanger must be 
connected to the mains via an all-pin 
isolating device to overvoltage catego-
ry III (IEC 61 058-1).

The air/water heat exchanger is not de-
energised until all of the voltage sources 
have been disconnected!
Switch off the power supply to the air/
water heat exchanger before opening 
the electrical connection box and before 
working on the water circuit, and take 
suitable precautions against it being ac-
cidentally switched on again.
The power supply must not be switched 
back on until the cover plate of the elec-
trical connection box has been properly 
screw-fastened into position.

Caution!

Never use flammable liquids for cleaning 
the air/water heat exchanger.
There is a risk of cutting injury around all 
drill holes and cut-outs which have not 
been fully deburred, especially during 
mounting of the air/water heat exchang-
er.

Avertissement !

Veuillez tenir compte du poids de levage 
maximal autorisé pour les personnes et 
le cas échéant utilisez un appareil de le-
vage.
Seuls les électriciens spécialisés ou les 
personnes dûment instruites opérant 
sous la direction et la surveillance d'un 
électricien spécialisé, sont autorisés à 
pratiquer des interventions sur les instal-
lations ou appareils électriques, confor-
mément aux règles de l'électrotech-
nique.
Les personnes mentionnées ci-dessus 
ne sont autorisées à raccorder l'échan-
geur thermique air/eau qu'après avoir lu 
ces informations !
Utiliser exclusivement des outils isolés.
Respecter les directives de raccorde-
ment du fournisseur d'électricité com-
pétent.
L'échangeur thermique air/eau doit être 
raccordé au réseau par l'intermédiaire 
d'un dispositif de coupure monophasé 
de catégorie III de surtension (CEI 
61 058-1).

L'échangeur thermique air/eau est hors 
tension uniquement après avoir débran-
ché toutes les sources de tension !
Mettre l'échangeur thermique air/eau 
hors tension avant d'ouvrir le boîtier de 
raccordement électrique ou de travailler 
sur le circuit d'eau et prévenir toute re-
mise en circuit inopinée.
La mise sous tension doit avoir lieu uni-
quement lorsque la face avant en tôle 
du boîtier de raccordement électrique 
est correctement vissée.

Prudence !

Ne jamais utiliser de liquides inflam-
mables pour le nettoyage de l'échan-
geur thermique air/eau.
Il y a risque de coupures au niveau des 
perçages et découpes qui ne sont pas 
complètement ébavurés, en particulier 
lors du montage de l'échangeur ther-
mique air/eau.
