Always check the refrigerant to be used.
Always use the specified refrigerant.
Prepare materials / tools matched to the refrigerant.
Air purging by refrigerant gas is strictly prohibited.
Use a special vacuum pump with reverse check mechanism.
Seal with nitrogen up to 4.2 MPa.
After 24 hours, check wether the pressure in piping has not 
descended.
Calculate the refrigerant additional charging amount, and 
charge a suitable amount. (Using a special R410A gauge
manifold and charging hose.)
Do not connect to the power source.
Use copper tube matching the specified material and 
thickness to meet endurance pressure of the pipe. (4.2 MPa)
Do not use pipes contaminated with dust and dirt during 
piping connection work.
