10. OPERATING LIMITS
If the appliance is supplied with chilled water, the condensation forming on the heat exchanger will
be drained via the condensation drain connection.
At very low chilled water temperature and very high humidity, condensation may form on compo-
nents other than the heat exchanger. This is not collected in the condensation drain, but might drip
from under the appliance.
To avoid this, a minimum permitted water temperature must be taken into account in function of the
relative humidity and temperature of the ambient air.

Mark the fastening points, using those on the unit or according to the dimensions specified on page 8 and 10 in this manual. Slightly
tilt towards the condensate drain to help the water drain. Respect the free space around the unit as shown on page 7-11. The type of
wall/ceiling determines what type of screw or plug should be used. For installation on drybottom: make sure that the holes line up with
supporting studs.
