6.3 Flow rates
(1) Heating mode with underground loop, indoor supply at 35°C, outdoor 0°C/-3°C
(2) Heating mode with ground water, indoor 30°C/35°C, outdoor 10°C/7°C
* If greater, install an additional or bigger expansion vessel
** in nominal mode 0/-3°C 30/35°C

Min. flow rates: these flow rates must be observed. Failure to do so may lead to destruction of the exchanger due to
freezing. CIAT shall not be held liable for damage from frost caused by flow rates below the minimum rates specified
below.
Nominal flow rates: these flow rates must be used to size all of the system's hydraulic components.
To keep your unit running at optimum performance, we recommend using the nominal flow rate.
6.2 Sound levels
Sound pressure level in HEATING mode at 5 metres, 1.5 metres from ground, in a free field, directivity 2.
