PART II-18
SAFETY
Intended use
The INDUSAIL SONIC plus and INDUSAIL SONIC air lighting sails are used for cooling indoor spaces. The unit is designed
for non-condensing operation. Consequently, the cold water supply temperature must be selected depending on the
temperature and humidity of the air drawn into the unit.
The supply air should not fall below the dew point temperature, to prevent condensation on the surfaces of the outdoor air
plenum box and/or sail. The INDUSAIL SONIC must not be used as a safety-related component or for performing any safety-
relevant function.
Observe the permissible operating and environmental conditions specified in section "Application area" (PART II-3). All
information contained in these operating and maintenance instructions is based on the currently applicable standards and
regulations, as well as the latest engineering standards. The manufacturer accepts no liability for damage caused by:
P
Incorrect use
P
Failure to observe these instructions
P
Installation and operation by untrained technical personnel
P
Technical changes to/manipulation of the unit
P
Failure to observe the maintenance intervals
P
Use of non-approved spare parts
Prevent condensation!
Condensation can occur on the heat exchanger if the cold
water temperature is below the dew point of the ambient
air. The Kiefer INDUSAIL SONIC plus is not designed for
condensing operation. Consequently, it must be ensured
that the setting for the supply water temperature prevents
it from falling below the dew point. If necessary, the water
temperature must be modulated according to the room air
humidity. The design engineer must take account of this as
early as the project planning stage.
The following instructions must be observed:
P
In the case of window ventilation or ventilation without dehumidification, outdoor air with high humidity can
enter the room when the window is opened, causing the temperature to fall below the dew point of the air.
It must be ensured that the central cold water controller induces a weather-dependent increase of the cold
water supply temperature.
P
It is important to ensure that water pipes and fittings are insulated.
Installation of an on-site dew point and condensation
monitoring system is recommended for hygiene and safety
reasons. It must be ensured that the temperature does not
fall below the dew point at any time.
