All preventative maintenance described over here is considered for operating under normal conditions. In case the conditions are largely requested and
there is a risk of environmental contamination, the frequency of actions must be more intense.

Install the manometers and register the pressures, temperatures and conditions of the suction line;
Check the refrigerant gas load;
Visually inspect if there are signs of wear out and deterioration on the tubes and hoses;
Change the dryer filter at least once a year or each time the system is opened;
Check the opening and closure pressure;
Check the compressor's efficiency;
