8. OPERATIONAL
LIMITS
Note:
1 In SUMMER mode, the unit can be started with
external air 46°C and inlet water 35°C.
In WINTER AND RECOVERY MODE, the unit
can be started with external air -15°C and inlet
water 20°C.
In these conditions, operation is only allowed for
a short amount of time and to bring the system to
the proper temperature.
To shorten this operation, it is recommended to
install a three-way valve which makes it possible
to bypass the water from the utilities to the plant,
until achieving conditions which allow the unit to
work within the allowed operating limits.

ATTENTION
In windy areas, for correct operation
of DCPX it is recommended to install
a windbreak barrier.
It should be installed if wind velocity
is beyond 2.5 m/s.
