66 Installation sequence Hydraulic connections For the arrangement of the hydraulic connections, see page 10. Connecting the primary circuit! Please note The components used must be resistant to the heat transfer medium. Never use zinc-plated/galvanised pipes. 1. Equip the primary circuit with an expansion vessel and safety valve (in accordance with DIN 4757). Note Expansion vessel must be approved to DIN Diaphragms of expansion vessel and safety valve must be suitable for the heat transfer medium. Blow-off and drain lines must exit into one container that can hold the maximum possible expansion volume of the heat transfer medium. 2. Ensure adequate thermal and sound insulation of all pipes routed through walls. 3. Connect primary lines to heat pump. Please note! To prevent equipment damage, connect on-site primary lines to the heat pump so that they are free of load and torque stresses. Please note! Make tight hydraulic connections on the primary side. In the case of hose outlets, ensure diaphragm grommets are seated correctly. If necessary, seal with sealing tape. 4. Insulate lines inside the building to provide protection from heat and vapour diffusion. 5. Fill the primary circuit with Viessmann heat transfer medium and vent. Note Viessmann heat transfer medium is a ready-mixed ethylene glycol-based medium, for down to 15 C, containing inhibitors for corrosion protection. Note For diaphragm grommets, see page

67 Installation sequence Hydraulic connections (cont.) Connecting the secondary circuit 1. Equip the secondary circuit on site with an expansion vessel and safety assembly (in accordance with DIN 4757). Fit the safety assembly to the on-site line in the heating water return. 2. Connect secondary lines to heat pump (7 28 mm). Please note! To prevent equipment damage, connect on-site secondary lines to the heat pump so that they are free of load and torque stresses. Please note! Make tight hydraulic connections on the secondary side. In the case of hose outlets, ensure diaphragm grommets are seated correctly. If necessary, seal with sealing tape. 3. Fill and vent secondary circuit. 4. Thermally insulate pipes inside the building. Note For diaphragm grommets, see page 104. In underfloor heating circuits, integrate a temperature limiter on site for limiting the maximum temperature of underfloor heating systems. Safeguard minimum flow rate, e.g. with overflow valve (see Specification on page 152). Installation 67

69 Installation sequence Electrical connections (cont.) Routing cables to the connection area Danger Damaged cable insulation can cause injury and damage to the appliance. Route cables so that they cannot touch very hot, vibrating or sharpedged components. When routing the on-site power cables, observe the location of the cable entries into the appliance via its back panel (see page 10). Danger Incorrectly routed wiring can lead to serious injury from electrical current and result in equipment damage. Route LV leads < 42 V and cables > 42 V/230 V~/400 V~ separately. Strip the insulation from the cables as close to the terminals as possible, and bundle tightly to the corresponding terminals. Secure cables with cable ties. This ensures that, should there be an error, for example when detaching a wire, the wires cannot drift into the adjacent voltage area. Installation 69

Power supply Isolators for non-earthed conductors The mains isolator (if installed) must simultaneously isolate all non-earthed conductors from the power supply with a minimum contact separation of 3 mm. We additionally recommend installing an AC/DC-sensitive RCD (RCD class B ) for DC (fault) currents that can occur with energy efficient equipment. If no mains isolator is installed, all nonearthed conductors must be isolated from the power supply by the upstream circuit breaker with at least 3 mm contact separation. Danger Incorrectly executed electrical installations can lead to injury from electrical current and result in equipment damage. Make the power supply connection and implement all protective measures (e.g. RCD circuit) in accordance with the following regulations: IEC VDE regulations Technical connection requirements specified by your local power supply utility Protect the power supply to the heat pump control unit with 16 A max. Danger An absence of component earthing in the system can lead to serious injury from electrical current if an electrical fault occurs. Connect the appliance and pipework to the equipotential bonding of the house in question. 94

95 Installation sequence Power supply (cont.) Danger Incorrect wire allocation can cause severe injury and damage the appliance. Never interchange wires "L" and "N". In negotiations with your power supply utility, different supply tariffs for the main power circuits may be offered. Observe the technical connection requirements of the power supply utility. If the compressor and/or instantaneous heating water heater (if installed) are operated at an economy tariff (power-off), provide an additional cable (e.g. 3 x 1.5 mm 2 ) for the power- OFF signal from the distribution board (meter box) to the heat pump control unit. The allocation of the power-off (for compressor and/or instantaneous heating water heater) is made via the type of connection and by setting parameters in the heat pump control unit. In Germany, the power supply can be cut off for up to 3 x 2 hours per day (24 h). The heat pump control unit/pcb must be supplied without blocking by the power supply utility; tariffs that are subject to possible shutdown must not be used here. The power supply to the heat pump control unit (3 x 1.5 mm 2 ) and the cable for the power-off signal can be combined in a 5-core cable. Protect the power supply to the heat pump control unit with 16 A max. For accessories and external components that are not to be connected to the heat pump control unit, make the power connection with the same phase as the heat pump control unit; we recommend using the same fuse/ MCB. Connection to the same fuse/mcb provides additional safety when the power is switched off. Observe the power consumption of the consumers connected. Information regarding the compressor power supply Please note! An incorrect phase sequence can cause damage to the appliance. Make the compressor power supply only in the phase sequence specified (see terminal) with a clockwise rotating field. Characteristics of the compressor power fuses: see "Specification".
