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.

• 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
• When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe and drain
cap. If the drain pipe and drain cap are used, the drain water in the pipe may freeze in extremely
cold climate. (For reverse cycle model only.)
• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it
might become difficult to get warm, and it is likely to cause product malfunction. Construct a
canopy and a pedestal, or place the unit on a high stand that is locally installed.

6. External input and output
With using external input and output functions, this product can be operated inter-connectedly with
an external device.
Connector Input Output Remarks
CN19 Low noise mode — See external input/output
settings for details.
Peak cut mode —
CN18 — Compressor status
6-1. External input
With using external input function, on/off status of “Low noise mode” and “Peak cut mode” can be
specified by the external signal.
¢Low noise mode
In following condition, the operating noise of the outdoor unit reduces comparing from the one in nor-
mal operating condition:
The air conditioner is set to the “Low noise mode” when closing the contact input of a commercial
timer or on/off switch to a connector on the control PCB of the outdoor unit.
NOTE: Product performance may drop depending on some conditions such as the outdoor temper-
ature.
