When the conditions as shown at
left cannot be met, following
alternative solution may be taken.
2)
Places where perfect drainage can be prepared and sufficient drainage gradient is available.
3)
Places free from air disturbances to the air inlet and outlet of the indoor unit.
4)
Places with the environmental dew-point temperature is lower than 28°C and the relative humidity is less than 80%.
This unit is tested under ISO installation conditions to make sure that there are no defects. However, if it is operated
under conditions of high humidity that exceed the conditions above, there is danger of condensate falling from
the unit. If there is a possibility that the unit will be used under such conditions, dress 10~20 mm of insulation on
the entire unit body, the piping and drain pipe.
5)
Do not place where the unit is exposed to oil splashes or steam (e.g. kitchens and machine plants).
(Installation and use at such places will cause the performance drop, corrosion in the heat exchanger and damage in molded
synthetic resin parts.)
6) Do not place where corrosive gas (such as sulfurous acid gas) or infl ammable gas (thinner, gasoline, etc.) is generated or
remains.
Installation and use at such places will cause corrosion in the heat exchanger and damage in molded synthetic resin parts.
7)
Do not place adjacent to equipment generating electromagnetic waves or high-frequency waves such as in hospitals, Gener-
ated noise may cause malfunctioning of the controller.
