1. Function

The electrical tted heaters of the R series are the main heater for electrically heated hot water heaters. Under normal circumstances, they do not require any maintenance or other service intervention. However, if the lime concentration of the water is very high, it may be necessary to remove the boiler scale at certain intervals. The user sets the desired temperature using the control dial. During the heating interval determined by the relevant utility, the temperature controller automatically switches the heater on and off (when the selected water temperature for the storage tank is reached). When the water temperature drops, for instance when water is retrieved from the tank or as a result of natural cooling, the heater is switched on again until the actual water temperature in the storage tank coincides with the preselected water temperature again.

2. Saving energy

Selecting a low water temperature setting for the water in the storage tank saves a lot of energy. Consequently, it is advisable to set the innitely variable temperature controller to the lowest temperature setting required for your actual hot water consumption. This reduces your electricity consumption and the lime deposits in the tank.

3. Operation and temperature setting

With the innitely variable temperature controller, set the intank water temperature that suits your requirements, or select one of the three suggested settings. In this way, you can ensure that your tted heater works efciently without wasting energy. To help you select an appropriate setting, the temperature control dial of the electrical heater features 4 suggested settings marked as follows:

Setting:  Frost protection for the tank (30 °C) Setting:  approximately 40° C, hand-hot tank water

Setting: •• approximately 65° C, moderately hot tank water This setting is recommended to avoid accidental scalding with hot water. Furthermore, the heater uses energy very sparingly if this setting is selected. The heat losses are small and the formation of boiler scale is largely prevented.

Low active standby energy consumption

Setting: ••• approximately 85° C, hot tank water

Caution:

Turning the controller counter-clockwise until the limit stop does not set the unit to zero or switch the unit off. If the unit feeds on daytime electricity, do not select a temperature

setting higher than •• (approx. 65°C).

Due to the hysteresis of the temperature control (± 7K) and possible radiation losses (cooling-down of the pipelines), the temperature specications are subject to an accuracy of ± 10K.

REU - RDU - RDW - RSW - RUL

4. Operating conditions

Use tted heater exclusively in the conditions specied on the rating plate (operating pressure, heating time, supply voltage etc.). The electrical connection must be made according to

the wiring diagram on the inside of the protection cover.

Apart from the nationally acknowledged rules and regulations (ÖVE = Association of Austrian Electrical Engineers, VDE = Association of German Electrical Engineers, ÖNORM = Austrian standard and DIN = German standard, etc.), the connection conditions of the local power station and waterworks as well as the Operator’s Manual and Installation Instructions must also be observed. If the lime concentration of the water is very high, we recommend tting a commercially available decalcier upstream of the water tank. This tted heater is particularly suitable for the installation in freestanding enamelled tanks and units with twin envelope. However, due to its special design, the units can also be tted in third-party products with enamelled, plastic coated or hotdip galvanised boilers. A combination with CrNi (NIRO) boilers is problematic and not recommended (necessary measures: see item 5.4). For the installation in enamelled boilers, our tted heaters, screw-in heaters and tted gilledpipe heat exchangers are designed with insulated heating elements in connection with a protective current discharge resistor and therefore comply with the state of the art – in particular concerning the protection against corrosion of enamelled boilers. All built-in heating components are suitable for pressure- resisting operation and the heating of drinking or heating water up to a max. operating pressure of 10 bar (150 psi).

Built-in heating systems are not suitable for use in aggressive media (alcohol, glycol, oil, etc.)!

This device is not designed to be used by persons (including children) with physical, sensory or mental disabilities or lacking experience and/or lacking knowledge, unless these are supervised by a person who is responsible for their safety or have received instructions on how to use this device from any such person. Children should be supervised in order to ensure that they do not play with this device.

5. Assembly, installation and safety information

5.1 General installation and safety information

In operation, the heating element and the sensor protection tube must be surrounded on all sides by sufcient water. The water ow resulting from thermal inuences should not be impeded. The tted heater features a safety temperature limiter that switches off any further heating of the unit when the water temperature reaches max. 110° C (EN 60335 -2-21; ÖVE-EW41, Pt 2 (500) / 1971). Therefore, when selecting the connection components (con-nection pipes, safety valve combinations, etc.), it is necessary to ensure that the connection components will withstand temperatures of 110° C so that any consequential

damage in the event of a malfunction of the temperature controller is prevented.

The assembly and installation must be performed exclusively by authorised trade personnel.

Horizontal installation in a horizontal tank

The length of the ange tube must not exceed max. 130mm in order to ensure that the temperature sensor and the heating element extend far enough into the boiler. The heater must be tted as low in the boiler as possible so that the entire content of the boiler is heated evenly. It is not essential that the heating elements extend throughout the available installation depth. In front of the boiler ange, some mounting space is required (installed length + 100mm). Boiler scale affects the function of the heater. If the lime concentration of the water is very high, it is necessary to take appropriate measures, for instance lowering the temperature, installation of softening equipment, removal of the boiler scale.

5.3 Installation of the ttet heater

Apart from the legally acknowledged rules and regulations, the connection conditions of the local power station and waterworks must also be observed.

1. Remove protection cover, Pos. 1.

2. Install heating ange, Pos. 2, with gasket, Pos. 3, in the boiler. During installation, the sensor protection tube of the temperature controller must be above the tubular heating elements (refer to “Notes on Installation”).

3. Fasten heating ange, Pos. 2, with M 12 ange bolts (max. torque: 22 Nm). Tighten ange bolts (after tightening a bolt, proceed with the bolt in the diagonally opposite position). Check the screw connection of the heating elements and if required retighten to a torque of 2-3 Nm.

4. Make the electrical connection according to the wiring diagram (see Items 5/6).

Important – do not forget to connect the protective conductor!

5. Attach protection cover and fasten with nut, put on enclosed control dial, Pos. 4.

6. Do not operate until the tank is lled with water.

5.4 Notes about protection against corrosion

The tted heater is designed for installation in a tank with inside enamelling with a protection anode. As delivered, the type series R…18 –… (ange diameter: 180mm) is equipped with an anode with a diameter of 22 mm, length: 390 mm. For enamelled boilers (third-party products), it is necessary to integrate an appropriate anode protection in the boiler according to the manufacturer’s specications.

The protection anodes must be replaced when more than

/4 of the material has been consumed. After approximately 2 years of operation, the anode should be checked for the rst time. The degradation products of the magnesium anode can precipitate as dissolved matter in the bottom area of the tank and also be rinsed out from the tank during the water withdrawal.

The following measures are required in the event of a combination with CrNi (NIRO) tanks or CrNi heat exchangers and built-in components in plastic coated tanks:

a) Disconnection of the protective current discharge resistor in order to ensure an

insulated installation of the heating element.

b) Disconnection of the anode – earth connection cable if the relevant type is

equipped with an anode.

c) Replacement of the brass sensor tube for a sensor tube made of stainless steel.

If an external current anode is retrotted, the magnesium anode installed must be removed as otherwise the functioning of the external current anode will be impaired.

5.5 Connecting water to the tank

The assembly, connection and usage instructions of the hot water heater (boiler), as well as ÖNORM (Austrian standard) B2531 T1 or DIN (German standard) 1988, must be observed

at all times.

Pressure-resistant connection

Any warranty is voided if inappropriate or defective tank connection ttings are used and/or if the stated operating pressure is exceeded.To make the water connection, it is mandatory to use a type-approved diaphragm safety valve or a diaphragm safety valve combination – connection tting for pressureresistant tanks! A safety valve combination consists of shutoff valve, test valve, return ow valve, drain valve and safety valve with expansion water discharge. It is installed between the cold water supply line and the cold water inlet (blue) of the tank in the sequence shown below.

5.6 Electrical connection

The installation of the heating element and commissioning must be carried out by a skilled person who assumes the responsibility for the proper execution and conguration in his/her capacity as a professional. As a basic rule, the electrical connection should be made as indicated on the enclosed, type-specic wiring diagram! Make sure the supply voltage is correct! All accessible metal parts of the tank must be covered by the safety/protection measure.

An allpole disconnector with 3 mm contact gap width must be integrated in the power supply line. An automatic circuit-breaker may also be used as the disconnecting device. The connecting cable must be introduced into the connection space of the tted heater through the attachment bolting. A cable grip (strain relief device) must be used for protection against pulling and twisting.

Id.Nr.: 242782-2 | 13

REU - RDU - RDW - RSW - RUL

The connection with the power grid must be implemented in conformity with the applicable national regulations and standards, the relevant connecting requirements of the local power company and waterworks, as well as the standards of the Mounting and Operating Instructions, and must be performed exclusively by a licensed electrician. The stipulated protective measures must be executed carefully, so that no other power-supplied devices are affected thereby in the event of a malfunction or failure of the hot water tank’s power supply (e.g. freezer, rooms used for medical purposes, units for intensive care, etc.). In rooms with bathtubs or showers, the device must be installed in accordance with the national laws and regulations (e.g. of ÖVE-SEV or VDE). The technical connecting requirements (TAB) of the relevant energy supply company must absolutely be observed. A residual current circuit breaker with a tripping current I before the electric circuit. The device must only be connected with permanently laid lines. An allpole disconnecting unit with at least 3mm contact clearance must be connected in series before the device. This requirement is fullled e.g. by an automatic cutout. It is imperative that the hot water tank is lled with water prior to electrical startup. In accordance with the safety regulations, the hot water tank must be switched powerless, secured against being switched on again and checked for powerlessness prior to any intervention. Interventions to the electrics of the device must only be performed by a licensed electrician. As a rule, the electrical connection must be performed in accordance with the circuit diagram afxed inside the connecting area of the tank!

Version with contactor control –RSW types

ÖVE (Association of Austrian Electrical Engineers) or VDE (Association of German Electrical Engineers) tested control contactors tted outside the housing of the tted heater, for instance in a control cabinet of the xed installation, must be used for installations and control contactors. Separate control contactors must be used for the safety temperature limiter and the temperature controller. The contactors must bear an inscription/label indicating their safety function for the water heater. (TR and STB (security temperature limiter).

≤30mA must be connected in series

∆n

The output data for the choice of the contactors is given in the table (Section: Technical Data) in the »Switching group« column. The STB (security temperature limiter) contactor must be designed for the total output of the switching groups. When the installation has been completed, the function of the contactors must be checked to ensure they work properly.

5.7 Commissioning

Commissioning: before the unit is switched on electrically for the rst time, the tank must be lled with water. As the water heats up, the expansion water produced in the inner boiler must drip from the safety valve if the connection is pressureproof and from the overow combination set if the

connection is unpressurised.

Caution: The hot water discharge pipe and parts of the safety tting can get hot.

After the tank has heated up fully, the temperature setpoint, the actual temperature of the retrieved water and the hot water quantity display should coincide roughly.

Should a device, at the point of delivery, clearly display a malfunction, damage or other defect, this must not be tted, installed or used in the system. Subsequent complaints regarding devices with an obvious defect which have been connected and installed are expressly excluded under the warranty

and guarantee.

REU - RDU - RDW - RSW - RUL

6. Checking, maintenance, care

The boiler scale as well as the furring that forms in the internal boiler of the storage tank in the case of heavily calciferous water must be removed by an expert after one to two years of operation. The cleaning is performed through the ange opening – de-install the built-in heater, clean the storage tank, use a new seal when mounting the heating ange. The internal tank of the water heater with special enamelling must not get in contact with boiler scale solvents – do not use an antiliming pump. Finally, the device must be rinsed thoroughly and the heating process be observed in the same way as during the rst commissioning. In order to be entitled to any claims for warranty, as provided, the installed reactive anode requires documented inspection by an expert in intervals of maximum 2 years of operation. Practically, the external current anode has an unlimited service life. Its function must be monitored regularly by means of the control lamp. This indicates two operating conditions: Green: system ok

Red, ashing: malfunction - call customer service!

Pre-requisite for awless functioning is that the tank is lled with water. For proper functioning of the external current anode, a conductivity of the medium of >150μs/cm The guard circuit shunt resistor must not be damaged or removed during maintenance works. Do not use any abrasive cleaning agents and paint thinners (such as nitro, trichlor etc.) to

clean the device.

The best cleaning method is to use a damp cloth added with a few drops of a liquid household cleaner. In hospitals and other public buildings, the prevailing regulations for cleaning and disinfection must be observed. During servicing works, it is advisable to open the cleaning and servicing ange in order to inspect the tank for any foreign objects that may have been washed in as well as any contamination, and to remove any such, if applicable.

is required.

7. Malfunctions

If the water in the tank is not heated, please check whether the circuit-breaker (MCB) in the distributor or the fuse has tripped. Also check the setting of the temperature controller. Please do not attempt to repair the defect in any other case. Either contact a licensed electrician or call our customer service department. A skilled person can often repair the unit in no time at all. When you call us to notify us of a defect, please always quote the type name and fabrication number, which you can look up on the rating plate of your tted heater.

Warranty, Guarantee and Product Liability

Warranty is made according to the legal provisions of the Republic of Austria and the EU.

1. The prerequisite for honoring of warranty terms on the part of the manufacturer (hereinafter referred to as Manu-

facturer) is presentation of a paid invoice for the purchase of the appliance in question, whereby the identity of the appliance including model and fabrication number must be indicated on the invoice and presented by the claim applicant. The General Terms and Conditions, Terms and Conditions of Sale and Delivery of the manufacturer shall apply exclusively.

2. The assembly, installation, wiring and startup of the appliance in question must, to the extent that this is prescribed

legally or in the installation and operation guide, have been performed by an authorized electrical technician or installer who has followed all the required regulations. The hot water tank (excluding outer jacket or plastic cover) must be protected from exposure to direct sunlight to prevent discoloration of the polyurethane foam and possible cracking of plastic parts.

3. The area in which the appliance is operated must be kept from freezing. The unit must be installed in a location where

it can be easily accessed for maintenance, repair and possible replacement. The costs for any necessary changes to the structural conditions (e.g. doors and passages too narrow) are not governed by the guarantee and warranty declaration and therefore shall be rejected on the side of manufacturer. When erecting, installing and operating the water heater in unusual locations (e.g. attics, interior rooms with water-sensitive oors, closets, etc.), provision must be made for possible water leakage and means provided for catching the water with a corresponding drain to avoid secondary damage in the context of product liability.

4. Warranty claims will not be honored for: inappropriate transport, normal wear and tear, intentional or negligent damage, use of force of any kind or description,

mechanical damage or damage caused by frost or also by exceeding the operating pressure stated on the rating plate, even if only once, use of connection ttings that do not comply with the standard, use of defective tank connection ttings and unsuitable and defective service ttings. Breaking of glass and plastic components, possible colour dierences, damage due to improper use, in particular non-observance of the mounting and operating instructions (Operating and Mounting Instructions), damage by external inuence, connecting to incorrect voltage, corrosion damage as a consequence of aggressive waters (water not suitable for drinking) in accordance with the national regulations (e.g. Austrian ordinance on drinking water, TWV – Fed. Law Gazette II No. 304/2001), deviations between the actual drinking water temperature at the tank tting and the specied hot water temperature of up to 10K (hysteresis of the controller and possible cooling due to pipelines), Continued use, despite the occurrence of a defect, unauthorised modications to the device, installation of additional components that were not tested together with the device, improperly carried out repairs, Insucient water conductivity (min. 150 µs/cm) operational wear of the magnesium anode (wearing part), natural formation of boiler scale, lack of water, re, ood, lightning, overvoltage, power failure or other types of force majeure. Use of non-original and company-external components such as e.g. heating elements, reactive anode, thermostat, thermometer, ribbed tube heat exchanger, etc., Parts installed in an uninsulated condition with respect to the storage tank, ingress of foreign particles or electrochemical inuences (e.g. mixed installations), failure to observe the design documents, unpunctual and undocumented renewal of the installed protective anode, no or improper cleaning and operation, as well as any deviations from the standard that reduce the value or functionality of the device only slightly. Fundamental compliance with all regulations in ÖNORM B 2531, DIN 1988 (EN 806), DIN 1717, VDI 2035 or the corresponding national regulations and laws must be ensured.

5. A justied claim must be reported to the closest customer service location of the manufacturer. The latter reserves the

right to replace or repair a defective part or to decide whether a defective appliance shall be replaced with a working one of equal value. The manufacturer furthermore expressly reserves the right to require that the purchaser return the appliance in question. The time of a repair or a replacement is determined by the production.

6. Repairs made under warranty are to be performed only by persons authorized by the manufacturer. Replaced parts

become the property of the manufacturer. If any repairs to the water heater become necessary as part of necessary service work, these are charged at the cost of repair and prorated material cost.

7. Any work performed without our express order, even this is done by an authorized installer, will void the warranty.

Assumption of the costs for repairs performed by third parties presumes that the manufacturer was requested to eliminate the defect and did not or did not in timely fashion meet his obligation for replacement or repair.

8. The warranty period will not be renewed or extended as a result of a guarantee and warranty claim, service or mainte-

nance work.

Id.Nr.: 242782-2 | 17

REU - RDU - RDW - RSW - RUL

9. Transport damage will only be inspected and if appropriate recognized if it has been reported in writing to the manu-

facturer no later than the weekday following delivery.

10. Claims exceeding the terms of the warranty, in particular those for damage and consequential damages, are precluded

insofar as these are legally permissible. Pro rata work times for repairs as well as the costs for restoring the equipment to its original condition must be paid in full by the purchaser. The guarantee provided extends according to this guarantee declaration only to the repair or replacement of the appliance. The provisions of the Terms of Sales and Delivery of the manufacturer remain, insofar as they are not altered by these guarantee conditions, fully in eect.

11. There is a charge for services provided outside of the context of these guarantee conditions.

12 In order for a warranty claim to be honored by the manufacturer, the appliance must be paid for in full to the manufac-

turer and the claimant must have met all his obligations to his vendor in full.

13. The enamelled internal boiler for water heaters is warranted for the specied period from the delivery date provided all

warranty terms described under Points 1 to 12 are observed with in full. If the warranty terms have not been met, the legal warranty requirements of the respective country from which the appliance was shipped shall prevail.

14. Claim satisfaction according to prevailing Austrian Product Liability Law: Claims for compensation under the title of product liability are only justied if all prescribed measures and necessities

for fault-free and approved operation of the appliance have been met. This includes among other things the prescribed and documented anode replacement, connection to proper operating voltage, prevention of damage due to improper use, etc. From these conditions it can be concluded that if all requirements are met (norms, installation and operation guide, general guidelines, etc.), the device or product fault resulting in the secondary damages would not have occurred. Furthermore it is mandatory that for processing of the claim the necessary documentation such as the part number and manufacturing number of the water heater, the seller’s invoice and that of the executing license holder as well as a description of the malfunction for a laboratory study of the appliance in question (absolutely required, since a specialist will study the appliance and analyze the cause of failure) be provided. To prevent misidentication of the water heater during transport, it must be marked with a highly visible and legible marking (preferably including address and signature of the end customer). Corresponding pictorial documentation indicating the extent of the damage, the installation (cold water line, hot water outlet, heating outgoing and return, safety xtures, expansion tank if present) as well as the defect location on the water heater is also required. Furthermore the manufacturer reserves the express right to require that the purchaser provide all the documents and equipment and equipment parts necessary for clarication. The prerequisite for performing services under the title of product liability is that it is the claimant’s obligation to prove that the damage was caused by the manufacturer’s product. Damage compensation according to the Austrian Product Liability Law is subject to a 500 Euro deductible. Until the entire matter is claried and the circumstances as well as determination of the causal factors are established, the manufacturer is held faultless. Nonobservance of the operating and installation guide and/or the relevant norms is considered negligent and will result in a liability disclaimer within the scope of compensation for damages.

The illustrations and data are not binding and may be modied without notice when technical improvements are made. Subject to printing errors and technical changes.

1. Fonction

Comme chauffage principal de chauffe-eau électriques, les éléments chauffants électriques de la Série R ne requièrent aucun entretien. Uniquement en présence d’une eau très calcaire, il

peut s’avérer nécessaire de détartrer les corps de chauffe de temps en temps.

L’utilisateur peut sélectionner la température souhaitée via le bouton sélecteur. Pendant la durée de montée en température dénie par votre société d’électricité, le régulateur de température allume automatiquement l’élément chauffant puis l’éteint une fois la température de l’eau du cumulus atteinte. Lorsque la température de l’eau baisse, par ex. suite à la consommation d’eau ou au refroidissement naturel, le chauffage se déclenche et reste en marche jusqu’à ce que la température présélectionnée soit de nouveau atteinte dans le cumulus.

2. Economies d’énergie

Limiter la température de l’eau du cumulus s’avère particulièrement économique. Pour cette raison, il est conseillé de choisir une température, réglable graduellement, réellement nécessaire à votre consommation d’eau chaude. Vous économiserez ainsi de l’électricité et minimiserez les dépôts calcaires dans le ballon.

3. Maniement et réglage de la température

Vous pouvez régler la température de l’eau dans le ballon, en fonction de vos besoins en eau chaude, soit graduellement soit sur l’un des quatre niveaux principaux clairement identiés. Ceci vous permettra d’utiliser l’élément chauffant encastré avec une plus grande efcacité énergétique.

Pour faciliter le réglage, 4 niveaux principaux sont marqués sur le bouton du régulateur de

température, à savoir :

Position :  protection antigel du cumulus (30°C) Position :  environ 40 °C, eau tiède Position : •• environ 65 °C, eau modérément chaude

Ceci est le réglage recommandé pour éviter des brûlures par inadvertance avec de l’eau trop chaude. En outre, l’appareil fonctionnera de manière particulièrement économique à cette température. Les déperditions de chaleur sont faibles et la formation de tartre est largement évitée.

Faible consommation d’énergie en veille. Position : ••• environ 85 °C, eau très chaude

Attention :

Le réglage du bouton du régulateur en butée à gauche n’équivaut pas une position « zéro »

et n’entraîne pas la mise hors tension de l’élément chauffant.

En fonctionnement diurne, il est déconseillé de régler une température supérieure à

•• (env. 65 °C).

En raison de l’hystérèse du régulateur de température (±7K) et d’éventuelles dissipations (refroidissement des tuyauteries), les températures sont indiquées avec une tolérance de ±10K).

4. Conditions de fonctionnement

L’utilisation de l’élément de chauffage encastré implique impérativement le respect des conditions indiquées sur la plaque signalétique (pression de service, durée de la montée en température, tension d‘alimentation, etc.). Le branchement électrique devra être

conforme au schéma collé sur le côté intérieur du capot de protection.

En plus de la législation et des réglementations nationales en vigueur (telles ce que celles de la Fédération autrichienne d’ingénierie électrique ÖVE, de la Fédération allemand de l’électrotechnique, de l’électronique et de la technique d’information VDE, des instituts de normalisation autrichien et allemand ÖNORM et DIN, etc.), vous devez également respecter les conditions de raccordement de votre fournisseur local d’électricité et d’eau, ainsi que les

instructions de montage et d’utilisation. Si votre eau est très calcaire, nous vous conseillons d’installer un adoucisseur d’eau du commerce en amont.

Cet élément chauffant encastré convient particulièrement pour être installé dans des

cumulus émaillés sur pieds ou à double paroi. Leur conception spéciale permet toutefois d’installer ces dispositifs également dans des appareils d’autres fabricants à revêtement émaillé, synthétique ou galvanisé à chaud. L’association avec des ballons CrNi (NIRO)

en revanche s’avère problématique et donc déconseillée (mesures nécessaires, voir sous point 5.4). En vue de leur installation dans des ballons émaillés, nos éléments

chauffants encastrés, corps de chauffe à vis encastrés ou échangeurs de chaleur avec tuyau

à ailette encastrés sont construits, avec des éléments de chauffe de construction isolante

en combinaison avec une résistance de saignée et correspondent ainsi à l’état actuel de la technique - notamment en matière de protection de ballons émaillés contre la corrosion.

Tous les éléments chauffants encastrés sont dimensionnés pour fonctionner à l’épreuve de

la pression et chauffer l’eau potable ou de chauffage sans toutefois excéder une pression de service de 10 bars.

Le chauffage intégré n’a pas été conçu pour fonctionner dans des milieux agressifs (alcool, glycol, huile, etc.) !

Cet appareil n’est pas destiné à être utilisé ou commandé par des personnes (y compris des enfants) aux capacités physiques, sensorielles ou mentales réduites ou qui n’ont pas l’expérience et/ou les connaissances requises à cet effet, sauf si elles sont sous la surveillance d’une personne chargée de leur sécurité ou ont reçu l’instruction nécessaire pour utiliser cet appareil de cette personne. Il convient de surveiller les enfants pour s’assurer qu’ils ne jouent

pas avec l’appareil.

5. Instructions de montage et d‘installation, consignes de sécurité

5.1 Consignes générales d‘installation et de sécurité

Lors du fonctionnement, le corps de chauffe et la gaine de protection de la sonde doivent immergés dans l‘eau. Les courants d’eau entraînés par les variations de température ne doivent pas être entravés.

L‘élément chauffant encastré est équipé d’un limiteur de température de sécurité qui arrête l’appareil lorsque l‘eau atteint une température de 110 °C max. (EN 60335 -2-21; ÖVEEW41, Partie 2 (500) / 1971). Il convient par conséquent de choisir les composants de raccordement (tuyaux, groupe de sécurité, etc.) qui peuvent résister, en cas de dysfonctionnement du thermostat, à des températures de 110 °C pour éviter tout dommage consécutif.

Le montage et l’installation sont strictement réservés à des professionnels autorisés.
