– The ventilation machinery and outlets are operating adequately and are not obstructed;
– If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for
the presence of refrigerant;
– Marking on equpment must alltime be visible and legible. Markings and signs that are
illegible need to be replaced.;
– The installation method for refrigeration pipe and components supports corrosion
protection against coolant. As long as material choice full on corrosion-protected
components (naturall sabsequently protection).
