STIEBEL ELTRON SH 10 SLi Electric Water Heater Instruction Manual

STIEBEL ELTRON SH 10 SLi Electric Water Heater Instruction Manual

SPECIAL INFORMATION OPERATION

– The appliance may be used by children aged 8 and older and persons with reduced physical, sensory or mental capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised.
– When permanently connected to the power supply using a dedicated junction box, the appliance must be able to be isolated from the mains power supply by an isolator that disconnects all poles with at least 3 mm contact separation.
– The power cable may only be replaced (for example if damaged) by a qualified contractor authorised by the manufacturer, using an original spare part.
– Secure the appliance as described in chapter “Installation / Installation”.
– Observe the maximum permissible pressure (see chapter “Installation / Specification / Data table”).
– Drain the appliance as described in chapter “Installation / Maintenance / Draining the appliance”.
– The appliance is pressurised. During the heat-up process, expansion water will drip from the safety valve.
– Install the safety valve in the cold water supply line.
– Regularly activate the safety valve to prevent it from becoming blocked, e.g. by limescale deposits.
– Size the drain pipe so that water can drain off unimpeded when the safety valve is fully opened.
– Fit the drain pipe of the safety valve with a constant downward slope and in a room free from the risk of frost.
– The safety valve drain must remain open to the atmosphere.

2. Safety

2.1 Intended use

This sealed unvented (pressurised) appliance is intended for heating domestic hot water. You can use the appliance to supply one or several draw-off points. This appliance is intended for domestic use. It can be used safely by untrained persons. The appliance can also be used in a non-domestic environment, e.g. in a small business, as long as it is used in the same way. Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of instructions for any accessories used is also part of the correct use of this appliance.

2.2 Safety instructions

Where children or persons with limited physical, sensory or mental abilities are allowed to use this appliance, we recommend a permanent temperature limit. A qualified contractor can set this limit.

Material losses
If the drain pipe of the safety valve is blocked, expanding water can lead to water damage.
Never close the drain pipe.

Material losses The user should protect the appliance and its tap against frost.

2.3 Test symbols

See type plate on the appliance.

3. Appliance description

The appliance constantly keeps the water content available at the preselected temperature. The appliance switches on automatically as soon as its temperature falls below the set value.
Subject to season, varying cold water temperatures can result in different maximum mixed water and outlet volumes.

Note A qualified contractor can set a temperature limit on the appliance (see “Installation / Settings / Setting the temperature limit”).
Note The appliance is under mains water pressure. The water volume increases as the cylinder is being heated up. During this process, expansion water drips through the safety valve. This is a necessary and normal process.

3.1 Operation

You can set any required DHW outlet temperature variably at the temperature selector. The heat-up indicator illuminates during the heat-up process.

1. Temperature selector
2. Heat-up indicator

Depending on the system, the actual temperatures may vary from the set value.
°C = Cold. On this setting, the appliance is protected from frost. The tap and the water line are not protected.
Eco = Recommended energy saving setting (approx. 60 °C), minor scaling
82 = Highest selectable temperature

4. Cleaning, care and maintenance

▶ Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.
▶ Check the taps regularly. Limescale deposits at the tap outlets can be removed using commercially available descaling agents.
▶ Have the function of the safety assembly checked regularly by a qualified contractor.
▶ Have the protective anode checked by a qualified contractor after the first 2 years of operation. The qualified contractor will then determine the intervals at which repeat checks should be performed.

Almost every type of water will deposit limescale at high temperatures. This settles inside the appliance and affects both the performance and service life. The heating elements should therefore be descaled if necessary. A qualified contractor who is aware of the local water quality will tell you when the next descaling is due.

5. Troubleshooting

6. Safety

Only a qualified contractor should carry out installation, commissioning, maintenance and repair of the appliance.

6.1 General safety instructions

We guarantee trouble-free function and operational reliability only if original accessories and spare parts intended for the appliance are used.

6.2 Instructions, standards and regulations

Note Observe all applicable national and regional regulations and instructions.
