CAUTION
• Check that duct work does not exceed the range of external static pressure of equip-
ment.
• Make sure to insulate ducts to avoid the dew condensation.
• Make sure to insulate between ducts and walls if metal ducts are used.
•
Please explain handling and washing methods of locally purchased materials to the
customer.
• To prevent people from touching the parts inside the unit, be sure to install grilles on
the inlet and outlet ports. The grilles must be designed in such a way that cannot be
removed without tools.
• When connecting the duct to the outlet port of the indoor unit, be sure to insulate the
outlet port and the installation screws to prevent water from leaking around the port.
• Set the static pressure outside the unit to 90 Pa or less (the allowable range is be-
tween 0 and 90 Pa.)

• Be sure to install the air inlet grille and the air outlet grille for air circulation. The cor-
rect temperature cannot be detected.
• Grills must be fi xed so that man cannot touch indoor unit fan and exchanger, and
cannot be removed by only hand operation without tool.
• Be sure to install the air fi lter in the air inlet.
If the air fi lter is not installed, the heat exchanger may be clogged and its perfor-
mance may decrease.
