Children must never play with the appliance. Cleaning and user maintenance must not be carried out by children without supervision. WARNING Injury / ! \ For safety reasons, only operate the appliance with the front casing closed. Material losses The system's active frost protection is not guaranteed if the power supply is interrupted. ► Never interrupt the power supply even outside the heating season. Note The DHW cylinder is under supply pressure. During the heat-up process, expansion water will drip from the safe¬ ty valve. ► If water continues to drip when heating is complet¬ ed, please inform your qualified contractor.

The appliance can be operated in conjunction with the following air source heat pumps: - HPA-0 05.1-07.1 CS Premium - HPA-0 7-13 (C)(S) Premium - WPL-A 05-07 HK 230 Premium - WPL15-25 A(C)(S)

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: - Heat pump manager - Highly efficient circulation pump for a heating circuit without mixer - 3/2-way diverter valve - Cylinder primary pump DHW cylinder The 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. The integral heat pump manager regulates the DHW heating to the required temperature. 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 into the buffer cylinder by the cylinder charging pump. When a demand is issued, the integral heating circuit pump delivers the heating water to the heating circuit. Heat pump manager (WPM) The system is controlled by means of the integral heat pump man¬ ager. Note The heat pump manager has an automatic summer/win- ter changeover so you can leave the system switched on in summer. ► Please observe the instructions for the heat pump manager.

10.1 Positioning the appliance

► 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

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 not be a shut-off valve between the heat gen¬ erator and the safety valve. Oxygen diffusion Material losses Do not use open vented heating systems. Use oxygen diffusion-proof pipes in underfloor heating systems with plastic pipework. 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). ► With heating systems that are permeable to oxygen, separate the heating system between the heating circuit and the buff¬ er cylinder. 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 • 1 Note ■ijThe maximum permissible line length between the ap¬ pliance and the heat pump will vary, depending on the version of the heating system (pressure drop). As a stand¬ ard value, assume a maximum line length of 10 m and a pipe diameter of 22-28 mm. ► Thoroughly flush the pipes before connecting the heat pump. Foreign bodies (e.g. welding pearls, rust, sand, sealing material, etc.) can impair the operational reliability of the system. ► Install the heating water pipes (see chapter "Specification Dimensions and connections"). ► Protect the flow and return lines against frost with sufficient thermal insulation. ► Connect the hydraulic connections with flat gaskets. 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. 10.2.1 HSBC 3-HKM (optional) 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.

15. Shutting down the system

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 ► 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 supply 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 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. Material losses Never use descaling pumps or descaling agents to clean the cylinder. ► Clean the appliance through the inspection flange. 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. www.stiebel-eltron.com HSBC 300 cool I 51 ENGLISHINSTALLATION Specification
