Refrigerant Piping
[REFRIGERANT]
This System use R-410A refrigerant.
Caution
This unit is already filled with a certain amount of R-410A.
Never open liquid and gas stop valve until the step Specified in “
CHECKS AFTER WORK
COMPLETION
”.
The refrigerant R-410A requires strict cautions for keeping the system clean, dry and tight.
Read the chapter “REFRIGERANT PIPING” carefully and follow these procedures correctly.
A. Clean and dry
Foreign materials (including mineral oils such as SUNISO oil or moisture) should be prevented
from getting mixed into the system.
B. Tight
Take care to keep the system tight when installing.
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.
Since R-410A is a mixed refrigerant, the required additional refrigerant must be charged in
its liquid state. If the refrigerant is charged in a state of gas, its composition changes and the
system will not work properly.
Be sure to perform refrigerant replenishment. Refer to
“
CHECKS AFTER WORK
COMPLETION
” and the label of instructions on refrigerant replenishment on the cover
surface of the control box,

Please fill in with indelible ink,
the factory refrigerant charge of the product,
the additional refrigerant amount charged in the field and
+
the total refrigerant charge amount
on the refrigerant charge label supplied with the product.
The filled out label must be adhered in the proximity of the product charging port (e.g. onto the
inside of the service cover).
[DESIGN PRESSURE]
Since design pressure is 3.8MPa or 38bar (for R-407C units: 3.3MPa or 33bar), the wall
thickness of pipes should be more carefully selected in accordance with the relevant local and
national regulations.
