4. Appliance description

The buffer cylinder and DHW cylinder with indirect coil are ar-ranged one above the other and can be separated for easier han-dling.The appliance has a plastic jacket with foam insulation and is equipped with a removable front casing. The appliance is connect-ed 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 HSBC300cool)DHW cylindersThe steel cylinder is coated on the inside with special direct enam-el and is equipped with a signal anode. The anode with consump-tion 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 cylinderThe steel cylinder provides hydraulic separation between the flow rates of heat pump and heating circuit. The heating water heat-ed 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.OPERATION Cleaning, care and maintenance www.stiebel-eltron.com HSBC 300 cool | HSBC 300 L cool | 39 ENGLISH

When positioning the appliance, observe minimum clearanc- es (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

Material losses The heating system to which the appliance is connected must be installed by a qualified contractor in accord- ance 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 gen- erator itself or in the flow line in close proximity to the heat generator. There must be no shut-off valve between the heat gen- erator 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 per- meable 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 set- tle in the heating system components, which may re- sult in a lower output or fault shutdowns due to reduced cross-sections. Supply lines The maximum permissible line length between the appli- ance 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 10m and a pipe diameter of 22-28mm. 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 trans- mission 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 pres- sure 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 "Specifica- tion/ 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.INSTALLATION Installation www.stiebel-eltron.com HSBC 300 cool | HSBC 300 L cool | 47 ENGLISH

Material losses Observe the temperature application limits and the min- imum circulation volume on the heat consumer side (see chapter "Specification/ Data table").

Material losses Drain the system when there is a risk of frost and the heat pump is completely switched off (see chapter "Mainte- nance/ Draining the DHW cylinder"). If you take the system out of use, set the heat pump manager to standby so that the safety functions that protect the appli- ance (e.g. frost protection) remain active.

WARNING Electrocution Carry out all electrical connection and installation work in accordance with relevant regulations. WARNING Electrocution Before any work on the appliance, disconnect all poles of the appliance from the power supply. Draining the buffer cylinder D0000080425 Drain the buffer cylinder via the drain valve. Draining the DHW cylinder CAUTION Burns Hot water may escape during draining. Close the shut-off valve in the cold water inlet line. Open the hot water taps on all draw-off points. Empty the DHW cylinder via the "cold water inlet" connection. Cleaning and descaling the DHW cylinder

Material losses Never use descaling pumps or descaling agents to clean the cylinder. Clean the appliance through the inspection port. For the torque of the flange screws, see chapter "Specification/ Dimensions and connections". Replacing the signal anode Replace the signal anode if it becomes depleted.INSTALLATION Specication 60 | HSBC 300 cool | HSBC 300 L cool www.stiebel-eltron.com
