frost.

2.3 Test symbols

See type plate on the appliance.

3. Appliance description

The appliance switches on automatically as soon as you open the

hot water valve on the tap. When you close the tap, the appliance

switches off again automatically.

The appliance heats water as it ﬂows through it. The DHW outlet

temperature can be variably adjusted.

From a certain ﬂow rate, the control unit regulates the correct

heating output, subject to the temperature selected and the cur-

rent cold water temperature.

The electronically controlled compact instantaneous water heater

maintains a consistent outlet temperature. This is irrespective of

the inlet temperature, up to the maximum output of the appliance.

If the appliance is operated with preheated water and the inlet

temperature exceeds the chosen set temperature, the water is

not heated further.

DHW temperature

The DHW outlet temperature can be variably adjusted.

Heating system

The bare wire heating system is enclosed within a pressure-tested

plastic jacket. The heating system with its stainless steel heater

spiral is suitable for hard and soft water areas and is largely in-

susceptible to scale build-up. The heating system ensures rapid

and efﬁcient DHW provision.

Note

The appliance is equipped with an air detector that large-

ly prevents damage to the heating system. If, during op-

eration, air is drawn into the appliance, the appliance

shuts down heating operation for one minute to protect

the heating system.

Risque de brûlure à des températures de sortie supé-

rieures à 43°C.

ATTENTION Brûlure

En cas de fonctionnement avec de l’eau préchauffée, pro-

venant par exemple d’une installation solaire, la tempé-

rature de l’eau chaude peut différer de la température

de consigne préréglée.

!

AVERTISSEMENT Blessure

2.3 Label de conformité

Voir la plaque signalétique sur l’appareil.

3. Description de l’appareil

L’appareil se met en marche dès que vous ouvrez le robinet d’eau

chaude. Lorsque vous fermez le robinet, l’appareil s’éteint auto-

matiquement.

L’appareil chauffe l’eau pendant qu’elle circule dans l’appareil. Il

est possible de régler progressivement la température de sortie

de l’ECS.

Au-delà d’un certain débit, la puissance de chauffe nécessaire est

régulée en fonction du réglage de température et de la tempéra-

ture de l’arrivée d’eau froide.

Le chauffe-eau instantané compact à régulation électronique

maintient la température de sortie constante jusqu’à la puissance

maximale de l’appareil et indépendamment de la température

d’arrivée de l’eau.

Si l’appareil est alimenté avec de l’eau préchauffée et que la tem-

pérature d’arrivée d’eau dépasse la valeur de consigne prédéﬁnie,

l’eau n’est plus chauffée.

Température ECS

Il est possible de régler progressivement la température de sortie

de l’ECS.

Système de chauffe

Système de chauffe à ﬁl nu enveloppé sous une gaine plastique

résistant à la pression. Très résistant à l’entartrage, ce système

de chauffe avec serpentin en acier inoxydable convient indiffé-

remment à l’eau faiblement et fortement calcaire. Ce système de

chauffe permet une alimentation en eau chaude sanitaire rapide

et efﬁcace.

3.2 Réglages recommandés

Votre chauffe-eau instantané assure un maximum de précision et

de confort pour la production de l’eau chaude sanitaire. Si vous

utilisez quand même l’appareil avec une robinetterie thermosta-

tique, voici quelques recommandations:

 Réglez la consigne de température à plus de 50°C sur l’ap-

pareil. Réglez ensuite la température de consigne souhaitée

au niveau de la robinetterie thermostatique.

Économies d’énergie

Voici les réglages que nous préconisons pour une consommation

minimale d’énergie:

- 38°C pour les lavabos, douches, baignoires

- 55°C pour les éviers

Protection interne anti-ébouillantement (installateur)

Si l’utilisateur le désire, l’installateur peut régler une limitation

de température permanente, par exemple dans les maternelles,
