L∞p by Daikin is part of Daikin's wider commitment to reduce our
environmental footprint. With L∞p by Daikin we want to create a
circular economy for refrigerants. One of the actions to achieve this,
is the reuse of reclaimed refrigerant in units produced and sold in
Europe. For more information about the countries that are in scope,
visit: http://www.daikin.eu/loop-by-daikin.
The refrigerant R410A 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
R410A does not contain any chlorine, does not
destroy the ozone layer, and does not reduce the
earth's protection against harmful ultraviolet radiation.
R410A 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
these procedures correctly.
Since design pressure is 4.0 MPa or 40 bar, pipes of larger
wall thickness may be required. The wall thickness of
piping must be carefully selected, refer to paragraph
"6.2. Selection of piping material" on page 4
details.
Do NOT connect the system to DIII-net devices:
This could result in malfunction or breakdown of the total system.
