Only charge refrigerant after performing a gas tightness test and vacuum drying.
Never charge more refrigerant than required as doing so can lead to liquid hammering.
Only use refrigerant R410A - charging with an unsuitable substance may cause explosions or accidents.
Use tools and equipment designed for use with R410A to ensure required pressure resistance and to prevent
foreign materials from entering the system.
Refrigerant must be treated in accordance with applicable legislation.
Always use protective gloves and protect your eyes when charging refrigerant.
Open refrigerant containers slowly.
Procedure
refrigerant
a tank of R410A refrigerant on a weighing scale. Turn the tank upside down to ensure refrigerant is
charged in a liquid state. (R410A is a blend of two different chemicals compounds. Charging gaseous R410A into
the system could mean that the refrigerant charged is not of the correct composition).
After vacuum drying (see Part 3, 4.9 D the blue and red pressure gauge hoses should still be
connected to the pressure gauge and to the master unit stop valves.
