MANTENANCE / COMPATIBLE FLUIDS
Cleaning water side
After having dismantled the exchanger, carry out the cleaning procedure by circulating de-greasing substance inside the radiator compatible with aluminium. Wash with hydraulic oil before reconnecting the cooler.
Cleaning air side
Carry out this procedure using water or compressed air. Make sure that the direction of the jet is parallel to the fins so that they are not damaged.
In order to obtain optimal results during this type of procedure we advise using a cleansing agent.
If the blockage of the exchanger is caused by build up of oil or grease, c1eaning can be carried out using a jet of steam or hot water.
During cleaning procedures the electric motor must be adequately protected.
During operation of heat exchangers observe following instructions:
