Test symbols

See type plate on the appliance.

Appliance description

The DHW is heated via a smooth tube internal indirect coil. You can use the appliance to supply one or more draw-off points.
The appliance is equipped with an inspection flange and ther-mometer.
The steel cylinder is coated on the inside with special directly applied “anticor®” 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.

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 in-stalled, 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 out-lets can be removed using commercially available descaling agents.

Troubleshooting

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

Safety

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

General safety instructions

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

Instructions, standards and regulations

Note
Observe all applicable national and regional regulations and instructions.

Appliance description

Required accessories

Depending on the static pressure, safety assemblies and pressure reducing valves are available. These type-tested safety assemblies protect the appliance against unacceptable excess pressure.

Additional accessories

Flanged immersion heaters are available as accessories.
If it is not possible to insert a rod anode from above, install a segmented anode.

Preparation

Installation site

Always install the appliance in a room free from the risk of frost and near the draw-off point.

• Ensure the floor is level. Use the adjustable feet to compensate for any unevenness in the floor.
• Ensure the floor has a sufficient load bearing capacity (see chapter “Specification / Data table”).
• Observe the room height and height when tilted (see chapter “Specification / Data table”).

Minimum clearances
The minimum side clearances can be swapped between left and right.

• Maintain the minimum clearances.

Transport

For transportation, the appliance is secured to the pallet with metal brackets.

• Remove the screws from the pallet.
• Turn the metal brackets to the inside of the adjustable feet under the appliance.

Removing the appliance from the pallet

Material losses
Rolling the appliance off the pallet can damage the sheet metal casing.

• Tilt the appliance using the adjustable feet to remove it from the pallet.
• Set the appliance down on the floor on the adjustable feet.

Installation

Heat exchanger connection

Flush the indirect coil with water before connection.

Oxygen diffusion
Material losses
Avoid open vented heating systems and underfloor heating systems with plastic pipes that are permeable to oxygen.

In underfloor heating systems with plastic pipes that are permeable to oxygen and in open vented heating systems, oxygen diffusion may lead to corrosion on the steel components of the heating system (e.g. on the indirect coil of the DHW cylinder, on buffer cylinders, steel radiators or steel pipes).

Material losses
The products of corrosion (e.g. rusty sludge) can settle in the heating system components, which may result in a lower output or fault shutdowns due to reduced cross-sections.

Water connection and safety assembly

Safety instructions

Note
Carry out all water connection and installation work in accordance with regulations.

Cold water line
Steel or copper pipes, or plastic pipework, are approved materials.

Material losses
A safety valve is required.

DHW line
Copper or plastic are approved materials for pipework.

Material losses
For the combined use of a threaded immersion heater and plastic pipework systems, observe the maximum permissible temperature and the maximum permissible pressure specified in chapter “Specification / Data table”.
Operate the appliance only with pressure-tested taps.

Connection

• Flush the pipework thoroughly.
• Observe the information in the installation instructions of the safety assembly.
• Connect the DHW outlet and the cold water inlet lines with the safety assembly. Please note that, depending on the stat-ic pressure, you may also need a pressure reducing valve.
• Connect the hydraulic connections with flat gaskets.
• Size the drain so that water can drain off unimpeded when the safety valve is fully opened. The safety valve discharge aperture must remain open to the atmosphere.
• Install the discharge pipe of the safety assembly with a constant slope.

Temperature sensor

• Bend the springs of the DHW sensor.
• Insert the DHW temperature sensor as far as it will go into the sensor well for the heat pump sensor flow.
• Fit the sensors for the control units used according to the relevant installation instructions (for sensor wells, see chapter “Specification / Dimensions and connections”).
• Route the connecting cable/lead to the heat pump control unit.

Commissioning

If using a flanged immersion heater

Material losses
Boiling dry destroys the high limit safety cut-out of the flanged immersion heater and the controller-limiter com-bination must then be replaced.

Material losses
If an indirect coil is installed in the same cylinder, its maximum temperature must be limited. This prevents the temperature limiter of the threaded immersion heater from responding.

• Fill the system with water.
  Turn the temperature selector to maximum.

• Switch the power supply ON.

• Check the appliance function.

• Check the function of the safety assembly.

Initial start-up

• Open a downstream draw-off point until the appliance is full and the pipes are free of air.
• Vent the internal indirect coil.
• Fit the accessories and check them if necessary.
• Check the safety valve for correct function.
• Check that the DHW temperature displayed on the heat pump control unit is correct.
