8. INSTALL THE CONNECTING PIPE
WARNING
• All field piping must be completed by a licensed
technician and must comply with the local and
national regulations.
• When the air conditioner is installed in a small
room, measures must be taken to prevent the
refrigerant concentration in the room from exceeding
the safety limit in the event of
refrigerant leakage. If the refrigerant leaks and its
concentration exceeds its proper limit, hazards due to
lack of oxygen may result.
• When installing the refrigeration system, ensure that
air, dust, moisture or foreign substances do not enter
the refrigerant circuit. Contamination in the system
may cause poor operating capacity, high pressure in
the refrigeration cycle, explosion
or injury.
• Ventilate the area immediately if there is refrigerant
leakage during the installation. Leaked refrigerant gas
is both toxic and flammable. Ensure there is no
refrigerant leakage after completing the installation
work.
Ensure that the length of the refrigerant pipe, the number
of bends, and the drop height between the indoor and
outdoor units meets the requirements shown in Table 8.1:
