MAINTENANCE
-
Air filtres: Clean air filters after 4 hours of system operation and every 3 months (or
depending on application). Filters can be cleaned by immersion in water and let dry or replace it.
-
Coaxial heat exchanger: One of the annual maintenance is to clean the coaxial exchanger. Should
be cleaned by circulating inside the heat exchanger countercurrent oxalic acid solution at 5% (95
parts water to 5 parts of oxalic acid), and check the pressure drop in the manometers to get proper
cleaning. After recovering the oxalic acid, washing the circuit, open the main keys and purge the
system before start up.
