(1) Cooling: outdoor air temperature 35°C; in/out water temperature 12/7°C.
(2) Cooling: outdoor air temperature 35°C; in/out water temperature 23/18°C.
(3) Heating: outdoor air temperature 7°C db 6°C db; in/out water temp 30/35°C.
(4) Heating: outdoor air temperature 7°C db 6°C db; in/out water temp 40/45°C.
(5) Cooling: in/out water temperature 7/12°C.
(6) Heating: average climatic conditions; Tbiv=-7°C; in/out water temp 30/35°C.
(7) Indicative data subject to changes. For the correct value, always refer to the technical label on the unit.
(8) Sound power level: heating mode condition (3); value determined based on measurements made in accordance with standard UNI EN ISO 9614-2, compliant
with that required by the Eurovent certification.
(9) Sound pressure level: value calculated from the sound power level using ISO 3744:2010

N.B. performance data are indicative and are subject to change. Furthermore the performance declared in
points (1), (2), (3) and (4) is intended to refer to instantaneous power according to EN 14511. The value
declared in point (5) and (6) is determined according to UNI EN 14825.
CAUTION: The minimum temperature allowed for storing the units is 5°C.

OPERATING LIMITS
12.1 EVAPORATOR WATER FLOW RATE
The nominal water flow rate refers to a 5°C temperature difference between the evaporator inlet and outlet.
The maximum permitted flow rate features a 3°C temperature difference while the minimum one has an 8°C
temperature difference at the nominal conditions as shown in the technical sheet.
Insufficient water flow rates can cause excessively low evaporation temperatures causing the
safety devices to trigger and stopping the unit and, in some extreme cases, forming ice in the
evaporator and resulting in serious failures to the cooling circuit.
For greater details, we have attached a table below with the minimum flow rates for the plate heat
exchanger to guarantee proper operation according to the model (please note: the water flow switch is
applied to protect against failed triggering of the antifreeze probe due to the lack of flow but does not
guarantee the minimum water flow rate required for correct operation of the unit).
