NOTES:
• Product fiche according to Commission Delegated Regulation (EU) 811/2013
• Acoustic noise information:
– The maximum sound pressure level is less than 70 dB (A) for both hydraulic unit and outdoor unit.
– According to IEC 704-1 and ISO 3744.
• If the air to water heat pump is operated under higher temperature conditions than those listed, the built-in protection circuit may operate to prevent internal circuit damage. Also, during
cooling modes, if the unit is used under conditions of lower temperatures than those listed above, the heat exchanger may freeze, leading to water leakage and other damage.
• Do not use this unit for any purposes other than the Heating and Cooling.

NOTES:
• Product information according to Commission Delegated Regulation (EU) 811/2013
• Product information is based on the average climate condition.
• *1: When using an optional component, this function is available.
• *2: For heat pump space heaters and heat pump combination heaters, the rated heat output Prated is equal to the design load for heating Pdesignh, and the rated heat output of a supple-
mentary heater Psup is equal to the supplementary capacity for heating sup (Tj).
• *3: If Cdh is not determined by measurement then the default degradation coefficient is Cdh = 0.9.
