(1) PED unit category: excluded from scope of PED due to article 1, item 3.6 of 97/23/EC.
(2) Operation area is extended to lower flow rates only in case the unit operated with heat pump only. (Not in startup, no backup heater operation, no
defrost operation).
(3) Including piping + PHE + backup heater; excluding expansion vessel.
(4) DB/WB7°C/6°C – LWC 35°C (DT=5°C)
(5) The sound pressure level is measured in an anechoice room at 1m distance from the unit. It is a relative value, depending on the distance and
acoustic environment. The sound pressure level mentioned is maximum possible value inside operation range of unit.
(6) >50°CBSH only, no heat pump operation.
(7) Above mentioned power supply of the hydrobox is for the backup heater only. The switch box and the pump of the hydrobox are supplied via the
outdoor unit. The optional domestic hot water tank has a separate power supply.
(8) Select diameter and type according to national and local regulations.
(9) Select diameter and type according to national and local regulations. Equipment complying with EN/IEC61000-3-12: European/technical
standard setting the limits for harmonic currents produced by equipment connected to public low-voltage system with input >16A and ≤75A per
phase.
(10) Above mentioned power supply of the hydrobox is for the backup heater only. The switch box and the pump of the hydrobox are supplied via the
outdoor unit. The optional domestic hot water tank has a separate power supply.
(11) >50°Cbooster heater only, no heat pump operation.
