How to use

Install the cooling unit according to enclosure manufacturer recommendations and Rittal mounting dimensions, ensuring proper sealing between the unit and cabinet panel. Connect to a 230 V AC supply using appropriate circuit protection and wiring practices. Set the internal thermostat or control to the desired temperature range for the protected equipment. Allow the unit to run continuously or according to load-driven on/off cycles; ensure filter elements and air paths remain unobstructed for efficient operation.

Recommendations

Place the unit where intake and exhaust airflow are not impeded, observe regular inspection and cleaning of filters and condensate paths, and verify electrical connections and protective devices during installation and periodic maintenance to maintain reliable cooling performance.
