3.7.3 Precautions on Refrigerant Piping
Do not allow anything other than the designated refrigerant to get mixed into the freezing
cycle (air, moisture,... ). If any refrigerant gas leaks while working on the unit, ventilate the
room thoroughly immediately.
Use R-410A only when adding refrigerant.
Make sure all installation tools are designed for use on R-410A refrigerant to withstand the
pressure.
Vacuum pump. Use a 2-stage vacuum pump with a non-return valve. Make sure the pump
oil does not flow oppositely into the new system while the pump is not working. Use a
vacuum pump which can evacuate to -100.7 kPa (5 Torr, -755 mmHg).
Check welded connections for gas leaks, if the local piping has welded connections.
3.7.4 Notes for Twin, Triple and Double Twin
Main piping (L1) can be re-used, size up & size down is allowed (see further in this section
for restrictions).
Re-use of branch piping is not allowed.
Branch piping (L2~L7) can be re-used, but standard pipe size only.
3.7.5 Selection of Piping Material
Construction material: phosphoric acid deoxidized seamless copper for refrigerant.
Temper grade: use piping with temper grade in function of the pipe diameter as listed in
table below.
The pipe thickness of the refrigerant piping should comply with relevant local and national
regulations. The minimal pipe thickness for R-410A piping must be in accordance with the
table below.
