Simple, reliable efficient heat pump! Equipped with µconnect controller HFC R410A CERTITA CERTIFIED * Cooling capacity: 5 to 16.5 kw Heating capacity: 6 to 19 kw *except 75HT OPTION HEAT PUMP HEATING (30/35 C 40/45 C) Use The air-to-water heat pump is designed for heating and cooling applications in new and existing individual homes and small businesses. When installed alone, is compatible with low to medium temperature emitters (underfloor heating, fan coil units, water cassettes, radiators, mixed installations, etc.). is also compatible with medium to high temperature emitters for boiler backup operation. With the SANI300L option, the heat pump can produce domestic hot water for the home all year round. The heat pump is installed outside in an open area, ideally as close as possible to the boiler room. Each device is tested in the factory and delivered ready for operation. Ranges The range of reversible heat pumps comprises 8 single-phase and three-phase models from 6 to 19 kw. Operation in cooling mode with an outdoor temperature down to -10 C. Operation in heating mode with an outdoor temperature of -15 C to +43 C. n If the heat pump is the only source of heat: Below this temperature, heating must be provided by a separate heating source or an additional electrical supply. Conformity n BT 2006/95 EC n NF C15-100 n EMC 2004/108/EC n EN 60-335 and EN 378-2 n If the heat pump is used for backup operation: Operates down to the equilibrium point (temperature below which the heat pump can no longer keep up with heating needs). Below this point, the heat pump and boiler run either alternately (heat pump OR boiler) or at the same time (heat pump AND boiler) as per the programming n DEP 97/23/EC Category 1 n WEEE 2002/96/EC n RoHS 2002/95/EC 1

INSTALLATION RECOMMENDATIONS Location units are designed to be installed outdoors on a home deck/patio or in a garden, preferably near to the machine room. Choose the location for the unit with care. Choose a location compatible with the environmental conditions (avoid installing near bedrooms (including neighbours' bedrooms, and areas where noise could reverberate, etc.) Ensure the recommended minimum clearances around the unit to allow easy access for installation and maintenance and ensure proper operation of the heat pump. (see Dimensions and Free space) Nothing should obstruct the air intake or discharge. Electrical connections All the information needed to wire the system is provided on the wiring diagram supplied with the unit. The diagram should be followed to the letter. Hydraulic connections Hydraulic connections are to be made in accordance with good engineering practice. Hoses must be installed on the unit's inlet and outlet for hydraulic connection. The system's pipes must also be held clear of the wall using anti-vibration mounts in order to prevent the transmission of noise and vibrations. As heat pump exchangers are sensitive to clogging, flush the lines thoroughly before connecting them to the unit. Install a < 600 μm screen filter to prevent fouling of the heat exchangers. The following accessories are essential to any hydraulic system and must also be installed: System drain connection at low point, Air vents at pipe high points, Sufficient system water capacity (see Technical characteristics), Buffer capacity or additional expansion vessel if necessary, Wiring must be carried out in accordance with accepted engineering practices and conform to current standards. A cut-off switch or circuit breaker must be installed on the electrical supply's outgoing line by the fitter. Commissioning Follow the instructions given in our installation and maintenance manuals.
