Condensation may occur in the system if the cooling unit is run at particular physical
operating parameters. This can be reduced by employing appropriate insulation or a
temperature-controlled regulation system.

The entire condenser is covered in a dirt-repellent, easy-to-clean special fin coating. In many applic
tions, therefore, the use of filter media is unnecessary, particularly with dry dusts.
To ensure the correct function of the cooling unit, the fins on the air-cooled condenser must be kept
clean. Cleaning must be undertaken at regular intervals of at least once a year; the frequency of
cleaning depends on the degree of soiling in the rooms where the unit is installed.
Risk of injury due to sharp-edged condenser fins! Use gloves as personal protection
The hot gas pipe inside the unit can reach a temperature of approx. 60°C. Wait
approx. 10 min. after you have switched off the unit to allow the pipe to cool down.
