* Due to continuing improvement, the above specifications may be subject to change without notice.
* Install the unit in an environment where the
wet bulb Temp. will not exceed 90°F (32°C).
* The unit is not designed for outside installations.
* Please don't use the steel material for the water piping material.
* The water circuit must use the closed circuit.
* Please do not use it as a drinking water.
* Please always make water circulate or add the brine to the circulation water when the ambient temperature becomes 32°F (0°C) or less.
* Please always make water circulate or pull out the circulation water completely when not using it.
* Please do not use groundwater and well water.
* The specification data is subject
to rounding variation.
