Important recommendations
To avoid death, injury, equipment or property damage, the following recommendations should be observed during
equipment operation:
1. The units are suitable for ambient air temperature between -20°C and +50°C and for air flow temperature
between -20°C and +40°C. Different conditions need written confirmation from the manufacturer.
2. The usual measure against frost in coils and protection against temperatures have to be secured by the user.
3. Components - Some OEM products have specific manufacturer's service instruction documents. These are
delivered with the Air Handling Unit. In this case, the indications in the OEM manual are valid and the service
handbook in hand has only general or complementary character for the relating components.
4. Liquid and gas storage -Maximum working pressure for all coils is 15bar. In case of coil connections to higher
working pressures, any warranty relating to coil tightness and personnel safety is excluded.
