Caution
C. Refrigerant R410A in the system must be kept clean, dry, and tight.
(a) Clean and Dry-Foreign materials (including mineral oils such as SUNISO oil,
moisture or air) should be prevented from getting into the system.
(b) 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 to the greenhouse effect if it is released. Therefore, take
proper measures to check for the tightness of the refrigerant piping installation.
D. Since R410A is a blend, the required additional refrigerant must be charge in its
liquid state. If the refrigerant is charged in a state of gas, its composition can change
and the system will not work properly.
E. During pump-down, stop the compressor before removing the refrigerant piping. If
the compressor ls still running and the stop valve is open during pump-down, air
will be sucked in when the refrigerant piping is remove, causing abnormally high
pressure which could lead to equipment damage or and personal injury.
F. If the system ahs a leak-detection system installed, it should be checked for leaks at
least every 12 months. Keeping a record of all leak checks for the lifetime of the unit
is strongly recommended.
1.5 Recycle:
A. Safely dispose of the packing materials
B. Refrigerant
1.6 Regulation:
A. In North America, installation must be performed in accordance with the
requirement of NEC and CEC (by authorized personnel only.) contact an authorized
service technician for repair or maintenance of the unit.
B. Dismantling the unit, treatment of the refrigerant, oil and additional parts must be
done in accordance with the relevant local state, and national regulations.
