1.1 What Is in This Chapter
Introduction As shown in the table below, we have grouped the maintenance in maintenance of the system and
standard checks.
Precautions Correct choices and decisions have to be made before any maintenance is done. Opening the
refrigerant circuit may cause a loss of refrigerant or lead to system contamination.
■ Avoid high gas concentrations.
While the heavy concentration of the refrigerant gas will remain on the floor level, good ventilation
is a must.
■ Avoid all contact with open fires or hot surfaces.
By high temperatures, the refrigerant gas R-134a may decompose into irritating and poisonous
gas. Avoid skin and hand contact with the liquid refrigerant and protect your eyes against liquid
splashes.
