Descriptions
1.1 Explanation of symbols
Warnings
The following keywords are defined and can be used in this document:
DANGER indicates a hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided,
could result in death or serious injury.

Important Information
Additional symbols
1.2 Safety instructions
Read all instructions before installing. Perform the steps in the indicated
sequence. Have the DHW tank inspected by a trained service technician
at least once every year. Failure to comply with these instructions can
result in severe, possibly fatal, personal injury as well as damage to
property and equipment.
Installation and servicing
Risk of fire from soldering and brazing!
Take appropriate protective measures when soldering and brazing as
the insulation is flammable, for example, cover the insulation.
Ensure that only a licensed contractor installs or services the DHW
tank.
Use installation material with adequate temperature stability.
Forbidden:
Connection of the potentiostat for an impressed current anode to the
magnesium anode installed in a storage tank is absolutely forbidden!
This would destroy the tank! The warranty would be voided.
Installation and commissioning
The electrical connection must be connected by a electrician.
The wiring diagram must be followed.
Do not install this device in rooms with a high moisture level
(e.g. bathrooms, saunas).
Function
To ensure that the tank functions properly, heed these installation
and maintenance instructions.
Never close the blow-off line of the T&P safety valve. For safety
reasons, water may escape during heating.
Danger from electric shock
Make sure that only certified electricians perform the electrical work.
Before performing electrical work, disconnect the power and secure
the unit against unintentional reconnection.
Ensure the system has been disconnected from the power supply.
Risk of scalding at the hot water draw-off point
When the DHW tank is in operation, temperatures in excess of 122 °F
(50 °C) can occur. To limit the temperature at the tap, install a
thermostatic DHW mixing valve.
Water heated for washing the laundry, dishes and for other cleaning
purposes can cause scalding and permanent injuries.
Children, elderly, and handicapped persons are more likely to be
permanently injured by hot water. Never leave such individuals in the
tub or shower unattended under any circumstances. Children must
not be allowed to operate hot water faucets themselves or to fill a
bathtub.
If the building has occupants in the above groups who operate hot
water faucets, or state laws / local ordinances stipulate specific
water temperatures, take the following precautions:
Use the lowest possible temperature setting.
To prevent scalding, install a tempering device, such as an
automatic mixing valve, at hot water tap or water heater. Select
and install the automatic mixing valve in accordance with the
valve manufacturer's recommendations and instructions.
Water exiting from drain valves can be extremely hot. To avoid
injuries:
Check that all connections are tight.
Direct exiting water away from people.
Measures must be taken to protect against excessive temperature
and pressure! Installation of a T&P safety valve is required.
The chart below shows the relationship between water temperature and
time until there is a risk of scalding. It can be used as the basis for
determining the safest water temperature for your application.
Warnings in this document are identified by a warning
triangle printed against a grey background.
Keywords at the start of a warning indicate the type and
seriousness of the ensuing risk if measures to prevent
the risk are not taken.
This symbol indicates important information where
there is no risk to people or property. It is separated by
horizontal lines above and below the text.

To protect against corrosion and ensure compliance with the rules for
electrical safety, observe the following points:
Use metal fittings for drinking water heating systems with plastic
piping.
Use only original accessories from the manufacturer.
When installation of the tank is complete, inspect the ground
conductor (including metal fittings).
Maintenance
Customers are advised to:
Sign a maintenance and inspection contract with an authorized
contractor. Inspect and maintain the DHW tank as necessary on a
yearly basis. Service as needed.
Use only original spare parts.
Flooding
After a flood, do not use the appliance if any part has been
submerged. Damage to appliances that have been submerged can be
quite severe and pose numerous safety risks.
An appliance that was subject to flooding must be replaced.
1.3 Instructions for the owner and operator
Explain the operation and handling of the heating system and DHW
tank, making a particular point of safety-relevant features.
Explain the function and how to check the T&P safety valve.
Hand all enclosed documents over to the owner/operator.
Recommendation for the user: Sign a maintenance and inspection
contract with a licensed contractor.
Highlight the following for the user:
Water may be discharged from the T&P safety valve during heat-
up.
The blow-off line on the T&P safety valve must always be kept
open.
Check that the T&P safety valve operates properly at least once
yearly.
The tank must be inspected annually and maintained as required.

Depressurize the heat exchanger.
Drain and blow out the heat exchanger.
To prevent corrosion, dry out the inner space and keep the
inspection port covers open.
7.2 Shutting down the heating system when there is a
risk of frost
Shut down the heating system and the DHW tank as shown in
Chapter 7.1.
8 Environmental protection/disposal
Environmental protection is one of the fundamental company policies of
the Bosch Group. We regard quality of performance, economy and
environmental protection as equal objectives.
Environmental protection laws and regulations are strictly adhered to.
To protect the environment, we use the best possible technology and
materials taking into account economic points of view.
Packaging
For the packaging, we participate in the country-specific recycling
systems, which guarantee optimal recycling. All packaging materials
used are environmentally-friendly and recyclable.
Old electrical and electronic appliances
Electrical or electronic devices that are no longer
serviceable must be collected separately and sent for
environmentally compatible recycling (in accordance
with the European Waste Electrical and Electronic
Equipment Directive).
To dispose of old electrical or electronic devices, you
should use the return and collection systems put in place
in the country concerned.
9 Maintenance
Allow the DHW tank to cool down sufficiently before performing any
maintenance.
Remedy all faults immediately.
Use original spare parts only!
The tank must be inspected annually and maintained as required.
Check the T&P safety valve annually.
9.1 Preparing the DHW tank for cleaning
Disconnect electrical power from the heating system.
Drain the DHW tank. To do so, close the shut-off valve for cold water
inlet and the open drain valve. To vent the system, open the air vent
valve or the highest faucet.
Remove the cleanout cover [6] shroud over the inspection port [1] in
the DHW tank.
NOTICE: Risk of equipment damage from excess
pressure! Excess pressure can cause stress cracking in
the enamel.
Never close the temperature and pressure safety
valve blow-off line.
Use only drinking water to check the DHW tank for leaks.
On the DHW side, the test pressure must not exceed
150 psi (10.3 bar) gauge pressure.
NOTICE: Risk of tank damage!
Residual moisture can result in corrosion.
Thoroughly dry out the inside (e. g. by means of hot
air) and leave the cleanout cover open.
WARNING: Risk of scalding from hot water!
Let the tank cool down sufficiently.
Drain the DHW tank completely, even the lower chamber
of the tank and the heat exchanger.
WARNING: Risk of scalding!
Hot water can cause scalding.
Prior to cleaning, allow the DHW tank to cool down

9.2 Descaling/cleaning the tank
Check the DHW tank interior for scale deposits (calcium).
Should limescale be discovered inside the DHW tank, proceed as
follows:
Hose down the inside of the DHW tank with a "high pressure"
(approx. 58 – 72.5 psi (4 – 5 bar) gauge pressure) stream of cold
water ( Fig. 20, page 16).
You can increase the cleaning effect by heating up the heat exchangers
in the drained DHW tank before cleaning. The thermal shock effect
releases scale deposits more easily from the coil-type heat exchanger.
Use a wet & dry vacuum cleaner with plastic suction hose to remove
the residues.
Extremely tough limescale inside the DHW tank can be removed by
chemical means. We recommend that you have a qualified contractor
carry out the chemical cleaning operation.
Fig. 20 Hosing down the interior of the DHW tank
9.3 Check the magnesium anodes
The purpose of the magnesium anode is to protect the storage tank
against corrosion.
Every year, check whether the magnesium anode must be replaced. The
surface of the magnesium anode must be free of deposits.
If the rod surface appears pitted, bumpy, rusty, deposits have built up on
the surface, or if the rod is less than 5/8" (15 mm) in diameter, then it
must be replaced.
Certain installations may require more frequent replacement of the
magnesium anode rod:
Recirculation connection
Poor water quality
Galvanic/electrolytic corrosion
High flow rate
In the event of poor water quality it is recommended that a water
treatment professional be consulted for water treatment options. The
DHW cylinder warranty is void if the magnesium anode is not correctly
maintained.
Checking the top magnesium anode
Remove PS top cover if not already removed.
Unscrew the magnesium anodes.
Check the magnesium anodes for degradation.
Replace the magnesium anode if the diameter has decreased to
approx. 5/8" (15 mm).
NOTICE: Risk of tank damage due to damaged enamel.
Never use hard objects or tools with sharp edges to
clean the interior of the tank.
6720 800 155-02.1ITL
The warranty is void if the magnesium anode is not
correctly maintained. Annual service records must be
kept in a safe location and submitted together with the
original purchase receipt in the event of a warranty
claim.
Never bring the magnesium anode surface into contact
with oil or grease.
Keep everything clean.

pect de ces consignes peut entraîner des accidents graves voire mortels
et/ou des dégâts matériels.
Montage et entretien
Risque d’incendie en raison des travaux de soudure !
L’isolation thermique étant inflammable, prendre des mesures de
sécurité appropriées pour effectuer tous les travaux de soudage, en
recouvrant l’isolation thermique par ex.
S’assurer que les travaux d’installation et de maintenance sont exclu-
sivement réalisés par un professionnel agréé.
Utiliser des matériaux suffisamment résistants aux températures éle-
vées.
Interdiction :
Il est formellement interdit de raccorder le potentiostat d'une anode
externe à l'anode au magnésium montée dans un ballon ! Le ballon serait
endommagé ! Le droit de garantie serait perdu.
Installation et mise en service
Le raccordement électrique doit être réalisé exclusivement par un
électricien. Respecter le schéma de connexion !
Ne pas monter cet appareil dans des pièces humides (par ex. salle de
bain, sauna).
Fonction
Respecter cette notice d’installation et d’entretien afin de garantir un
fonctionnement parfait.
Ne pas obturer la conduite de purge de la soupape de sécurité T&D.
Pendant le chauffage, de l’eau risque de s’écouler pour des raisons
de sécurité.
Risques d’électrocution
S’assurer que seuls des électriciens autorisés réalisent ces travaux
électriques.
Avant de commencer les travaux d’électricité, couper le courant du
câble d’alimentation sur tous les pôles et protéger l’installation
contre tout réenclenchement involontaire.
Vérifier que l’installation est hors tension.
Risques de brûlure aux points de puisage de l’eau chaude sanitaire
Les températures du ballon d’eau chaude sanitaire pendant son fonc-
tionnement peuvent dépasser 122 °F (50 °C). Pour limiter la tempé-
rature de puisage, installer un mélangeur thermostatique.
L’eau chauffée utilisée pour la lessive, la vaisselle et d’autres tâches
de nettoyage peut provoquer des brûlures et des blessures perma-
nentes.
Chez les enfants, les personnes âgées et sénile ou mentalement han-
dicapée, il existe un risque accru de blessure permanente à l’eau
chaude. Ne jamais laisser ces personnes sans surveillance dans la
baignoire ou sous la douche. Ne pas autoriser les jeunes enfants à
actionner eux-mêmes les robinets d’eau chaude ou de remplir une
baignoire.
Si dans un bâtiment les personnes comprises dans les catégories
précédemment citées actionnent des robinets d’eau chaude ou si les
directives locales imposent des températures précises pour les robi-
nets d’eau chaude, prendre les mesures spécifiques suivantes :
Utiliser le réglage de température le plus bas possible.
Installer une sécurité anti-brûlure, par ex. une vanne mélangeur
automatique, sur le robinet d’eau chaude ou le chauffe-eau. Choi-
sir et installer la vanne mélangeur automatique en fonction des
recommandations et consignes du fabricant de la vanne.
L’eau s’échappant des vannes de vidange peut être extrêmement
chaude. Pour éviter les blessures :
Assurer l’étanchéité des raccordements.
Eloigner les écoulements d’eau de toute personne.
Prendre des mesures de protection contre les températures et pres-
sions trop élevées ! Installer impérativement une soupape de sécu-
rité pour la température et la pression.
Le tableau suivant présente le rapport entre la température de l’eau et le
temps nécessaire à l’apparition de brûlures. Vous pouvez ainsi détermi-
ner les températures d’eau les plus sûres pour votre application.
Les avertissements sont indiqués dans le texte par un
triangle de signalisation.
En outre, les mots de signalement caractérisent le type
et l’importance des conséquences éventuelles si les me-
sures nécessaires pour éviter le danger ne sont pas res-
pectées.
Les informations importantes ne concernant pas de si-
tuations à risques pour l'homme ou le matériel sont si-
gnalées par le symbole ci-contre. Elles sont limitées par
des lignes dans la partie inrieure et supérieure du
texte.
