E. SAFETY PREVENTION MEASURES
• Before disassembling and inspecting
the air-conditioning system, please
read and obey the following safety pre-
WARNING
vention measures. If a repair or re-
placement is needed, it is required to
hire the authorized air-conditioning
engineer and use the approved equip-
ment for repairing. It is prohibited to
try to disassemble the air-condition-
ing system because the refrigerant
may be emitted to cause severe frost-
bite and injury.
IMPORTANT:
• Do not emit the refrigerant outside the air.
• Care shall be taken to handle the refrigerant to avoid
the failure.
• The skin and eyes may be frozen by direct contact
with fluid refrigerant.
• The refrigerant case and air-conditioning system
shall be maintained apart from the fire or heat, and
if the pressure increases, the explosion of the case
and the system can be happened.
• Direct contact with the fire or the hot metal surface
may cause the resolution of refrigerant and the gen-
eration of poisonous or acid products.
• In order to avoid the danger and injury, you are re-
quested to follow the requirements and simple pre-
vention measures as follow:

- Never emit the refrigerant to the air. When checking
the air-conditioning equipment, the authorized en-
gineer should operate the authorized refrigerant
recovery device.
- When discharging the refrigerant to the system, you
should check whether the ventilation status is good
on the assumption that the air circulation is good
and the system is located apart from the fire.
- In case of charging or discharging the system, it is
required to wear the protection glasses and obey
the proper measures to protect the face and espe-
cially the eyes from the accidental leakage of cool-
ing fluid.
- Oil and refrigerant mixture are pressed inside the
air-conditioning system. Consequently, as far as the
system is not discharged correctly, it is not allowed
to loosen the components or change the line.
- Before disconnecting, it is required to protect the
relevant device with a cloth and wear the gloves
and protection glasses to protect the skin and eyes
from the contact of a refrigerant.
- In case of accident, conduct as follow:
If the refrigerant touches the eye, wash the eye with
a large amount of sterilized water immediately and
go to the hospital to take medical measurements.
If the refrigerant touches the skin, wash the skin
with cold water and go to the hospital to take medi-
cal measurements.
