4. Appliance description

The buffer cylinder and DHW cylinder with indirect coil are arranged one above the other and can be separated for easier handling.

The appliance has a plastic jacket with foam insulation and is equipped with a removable front casing. The appliance is connected hydraulically and electrically to the heat pump. All hydraulic connections are made at the top (heating) and rear (DHW).

In addition to the DHW cylinder and the buffer cylinder, further system components are integrated:

• Highly efficient circulation pump for a heating circuit without mixer
• 3/2-way diverter valve
• Cylinder charging pump (only in HSBC 300 cool)

DHW cylinders

The steel cylinder is coated on the inside with special direct enamel and is equipped with a signal anode. The anode with consumption indicator protects the cylinder interior from corrosion.

The heating water heated by the heat pump is pumped through an indirect coil inside the DHW cylinder. The heat channelled through the indirect coil is thus transferred to the domestic hot water.

Buffer cylinder

The steel cylinder provides hydraulic separation between the flow rates of heat pump and heating circuit. The heating water heated by the heat pump is transferred to the buffer cylinder by the cylinder charging pump (only in HSBC 300 cool). When a demand is issued, the integral heating circuit pump delivers the heating water to the heating circuit.

5. Cleaning, care and maintenance

▶ Have the electrical safety of the appliance and the function of the safety assembly regularly checked by a qualified contractor.
▶ Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.

Signal anode with consumption indicator

Material losses

If the consumption indicator changes colour from white to red, have the signal anode checked by a qualified contractor and if necessary replaced.

1 2 D0000080281

1 White = Anode OK
2 Red = Requires checking by qualified contractor

Scaling

Almost every type of water will deposit limescale at high temperatures. This settles inside the appliance and affects both performance and service life. 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.
▶ Regularly activate the safety valve to prevent it from becoming blocked, e.g. by limescale deposits.

6. Troubleshooting

10. Installation

10.1 Positioning the appliance

▶ When positioning the appliance, observe minimum clearances (see chapter "Preparations / Installation site").
▶ Use the adjustable feet to compensate for any unevenness in the floor.

10.2 Heating water connection and safety valve

10.2.1 Safety instructions

Material losses

The heating system to which the appliance is connected must be installed by a qualified contractor in accordance with the water installation drawings in the technical guides.

Material losses

When fitting additional shut-off valves, install a further safety valve in an accessible location on the heat generator itself or in the flow line in close proximity to the heat generator.

There must be no shut-off valve between the heat generator and the safety valve.

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.

Supply lines

The maximum permissible line length between the appliance and the heat pump will vary, depending on the version of the heating system (pressure drop). As a standard value,
assume a maximum line length of 10 m and a pipe diameter of 22-28 mm.
▶ Insulate the flow and return lines in accordance with regional regulations.
▶ Connect the hydraulic connections with flat gaskets.

Pressure hoses against structure-borne sound transmission:

The appliance and the heat pump are connected to each other hydraulically via pipes carrying heating water. To reduce the transmission of structure-borne sound on the water side, connect the appliance to the heat pump with pressure hoses if these are not already installed in the heat pump.

Pressure differential:

If the available external pressure difference is exceeded, the pressure drop in the heating system could result in a reduced heating output.

▶ When sizing the pipes, ensure that the available external pressure differential is not exceeded (see chapter "Specification / Data table").
▶ When calculating the pressure drop, take account of the flow and return lines and the pressure drop of the heat pump.
The pressure drop must be covered by the available pressure differential.

10.2.2 Fitting the pump assembly (accessory) if required

WARNING Electrocution

Before starting work on the appliance, disconnect all poles from the power supply and drain the heating circuit via the drain valve on the buffer cylinder.

To extend the appliance with a heating circuit with mixer, you can install pump assembly HSBC 3-HKM (available as an accessory).
