IS DESIGNED FOR
The refrigerant R-410A requires strict cautions for keeping
the system clean, dry and tight.
Clean and dry
Foreign materials (including mineral oils such as
SUNISO oil or moisture) should be prevented from
getting mixed into the system.
Tight
R-410A does not contain any chlorine, does not
destroy the ozone layer, and does not reduce the
earth's protection against harmful ultraviolet radiation.
R-410A can contribute slightly to the greenhouse
effect if it is released. Therefore we should take
special attention to check the tightness of the
installation.
Read "6. Refrigerant piping" on page 4 carefully and follow
these procedures correctly.
Since design pressure is 4.0 MPa or 40 bar (for R-407C
units: 3.3 MPa or 33 bar), pipes of larger wall thickness may
be required. Refer to paragraph "6.1. Selection of piping
material" on page 4.
