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.

▶ 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

sufficiently.

Maintenance

SM80/5, SM100/5 – 6 720 800 156 (2017/07)16

▶ Loosen the hex bolts [5] in the cleanout cover [4].

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.

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
