OPERATING LIMITS
Note:
1 - In summer mode the unit can be started with
external air 46°C/114,8°F and water inlet
35°C/95°F. In winter mode the unit can be star-
ted with external air -15°C/5°F and water
inlet 20°C/68°F. Operate in such conditions is
permitted only for a short time and to bring the
system up to temperature. To reduce the time of
this operation, it is recommended to install
a three-way valve that allows bypassing water
from the system utilities, until the conditions
that allow the unit to work within the permitted
operation limits are achieved.
The devices in their standard configurations are not
suitable for installation in salty environments. For
the operating limits, refer to diagram, valid for
AHRI
standard conditions.
Wind breaks should be implemented if the unit is
installed in particularly windy areas, to prevent a
malfunction of the unit.
