Attention
Do not exceed permissible pressure range (see design data sheet).
To avoid freezing of the heating coil:
Add anti-freeze agent or install frost protection control on air, water or condensate side
depending on unit design.
To avoid any overheating damage to the unit, run steam coil only when fan is running
Provide air flow control or temperature limiter.

Inspection
Check inlet outlet connections for function (counter flow principle).
Charging
The system must be rinsed (removal of contaminations) according to VDI 2035 and should
be filled with the heat exchanger fluid named in the design data sheet to the correct
concentration. Water quality to VDI 2035. Too high a concentration of glycol leads to
reduced performance, too low a concentration of glycol can lead to frost damage.
