2-4 NOTE TO THE INSTALLER
Be sure to instruct customers how to properly operate (especially cleaning filters, operating different
functions, and adjusting the temperature) by having them carry out operations by themselves while reading
the manual literally.
3. SELECTING INSTALLATION SITE
Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
(1) Select an installation site where the following conditions are fulfilled and that meets with your cus-
tomer’s approval.
• Where optimum air distribution can be ensured.
• Where the floor is strong enough to withstand the
weight and vibration of the indoor unit.
• Make sure the floor is level. (Vibration and abnormal
noise may be generated.)
• Where nothing blocks the air inlet and outlet, and
where sufficient clearance for maintenance and
service can be ensured.
(Refer to Fig.2)
(If not ensured, the capacity may drop due to short circuit.)
• Where condensate can be properly drained.
• Where piping between indoor and outdoor units is
possible within the allowable limit. (Refer to the
installation manual for the outdoor unit.)
• Where there is no risk of flammable gas leakage.
(2) Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from
televisions or radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to elimi-
nate noise.)
(3) Investigate whether the installation location (such as the floor and wall) can withstand the weight
of the unit and, if necessary, reinforce the location with such as beams before installation. To
avoid vibration and abnormal noise, reinforce the location before installation.
(4) Pipework shall be protected from physical damage and shall not be installed in unventilated
space, if the space is smaller than the minimum size as defined in the table below (only for R32
refrigerant).
(5) Floor area where the indoor unit will be installed shall be higher than minimum required floor area
mentioned in table below (only for R32 refrigerant).
Minimum floor area for indoor unit.
