Selection of installation location
1) Avoid installation and use at those places listed below.
a) Places exposed to oil splashes or steam (e.g. kitchens and machine plants).
Installation and use at such places will incur deteriorations in the performance or corrosion with the heat exchanger or
damage in molded synthetic resin parts.
b) Places where corrosive gas (such as sulfurous acid gas) or inflammable gas (thinner, gasoline, etc.) is gnerated or
remains. Installation and use at such places will cause corrosion in the heat exchanger and damage in molded synthetic
resin parts.
c) Places adjacent to equipment generating electromagnetic waves or high-frequency waves such as in hospitals. Gener-
ated noise may cause malfunctioning of the controller.
2) Select places for installation satisfying the following conditions and, at the same time, obtain the consent on the part of
your client user,.
a) Places where chilled or heated air circulates freely. When the installation height exceeds 3m, warmed air stays close to
the ceiling. In such cases, suggest your client users to install air circulators.
b) Places where perfect drainage can be prepared and sufficient drainage gradient is available.
c) Places free from air disturbances to the return air port and supply hole of the indoor unit, places where the fire alarm
may not malfunction to short circuit.
d) Places with the environmental dew-point temperature is lower than 28˚C and the relative humidity is less than 80%.
( When installing at a place under a high humidity environment, pay sufficient attention to prevention of dewing such
as thermally insulating the unit properly.)
3) Check if the selected place for installation is rigid enough to stand the weight of thew unit.
Otherwise, apply reinforcement using boards and beams before starting the installation work.
