5.1. Operating conditions
• The maximum operating temperature is +150 °C.
• The maximum operating pressure is 1.0 MPa.
CAUTION
The coils of large units have been split in two. The condensation water drain of the coil has
to be piped to the sewer, also from behind the unit. Make sure that the water traps and
piping have been mounted according to the instructions.
CAUTION
Due to the construction, the heat exchanger will never drain completely. If the cooling
medium used is water, the heat exchanger may freeze up and become damaged at
temperatures below 0 °C.
