2.1 Intended use

The appliance is intended for domestic use. It can be used safely by untrained persons. The appliance can also be used in non-domestic environments, e.g. in small businesses, as long as it is used in the same way.
The appliance is intended for heating domestic hot water in conjunction with solar collectors and optionally with further heat sources for reheating the upper half of the cylinder.
Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of the instructions for any accessories used is also part of the correct use of this appliance.

2.2 Safety instructions
WARNING Burns
There is a risk of scalding at outlet temperatures in excess of 43 °C.

WARNING Injury
The appliance may be used by children aged 8 and up 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.

Material losses
The appliance is pressurized. During the heat-up process, expansion water will drip from the safety valve. If water continues to drip when heating is completed, please inform your qualified contractor.

Appliance description

The DHW is heated via two smooth tube internal indirect coils. In addition, a threaded immersion heater and a flanged immersion heater can be connected. You can use the appliance to supply one or more draw-off points. The appliance is equipped with an inspection flange and thermometer. The steel cylinder is coated on the inside with special directly applied “antic or ® ” enamel and equipped with a protective anode. This anode protects the inside of the cylinder from corrosion. The cylinder is surrounded by foam insulation and a painted sheet metal casing.

Cleaning, care, and maintenance

Have the function of the safety assembly and electrical safety of the fitted accessories regularly checked by a qualified contractor.
Have the protective anode checked by a qualified contractor after the first two years of use? The qualified contractor will then determine the intervals at which repeat checks should be performed.
Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.

4.1 Scaling

Almost every type of water will deposit limescale at high temperatures. This settles inside the appliance and affects both performance and service life. If a threaded immersion heater is installed, the heating elements must be descaled from time to time. A qualified contractor who knows the local water quality will tell you when the next service is due.

Check the taps regularly. Limescale deposits at the tap outlets can be removed using commercially available descaling agents.

Troubleshooting

Problem	Cause	Remedy
The flow rate is low.	The aerator in the tap or the shower head is scaled up or dirty.	Clean and/or descale the aerator or shower head.

If you cannot remedy the fault, notify your qualified contractor.
To facilitate and speed up your inquiry, please provide the serial number from the type plate (no. 000000-0000-000000):

Installation

9.1 Heat exchanger connection
Flush the indirect coils with water before the connection.
9.1.1 Water quality, solar circuit
A glycol/water mixture of up to 60 % is permitted for the indirect coil in the solar circuit, provided only dezincification-resistant metals, glycol-resistant gaskets, and diaphragm expansion vessels suitable for glycol are used throughout the system.

9.1.2 Oxygen diffusion
Material losses
Avoid open-vented solar thermal systems and plastic pipes which are permeable to oxygen.
With plastic pipes that are permeable to oxygen, oxygen diffusion can cause corrosion on the steel components of the solar thermal system (e.g. on the indirect coil of the DHW cylinder).
