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.

• If the space is larger than stated above, the condition will be the same as when there is no ob-
stacle.
• Height above the floor level should be 50 mm or more.
• When installing the outdoor unit, be sure to open the front and left side to obtain better operation
efficiency.
CAUTION
• Do not install the outdoor unit in two-stage where the drain water could freeze. Otherwise the
drainage from the upper unit may form ice and cause a malfunction of the lower unit.
• If the unit is installed in a region that is exposed to high winds, freezing conditions, freezing rain,
snow fall or heavy snow accumulation, take appropriate measures to protect it from those ele-
ments.To ensure stable operation, the outdoor unit must be installed on a raised stand or rack,
at or above the anticipated snow depth for the region. The installation of snow hoods and drift
prevention fencing is recommended when blowing and drifting snow is common to the region.
