10.2 - Electrical data, units with options 5 and 6
The electrical data of 30XW units with options 5 and 6 are
the same as for 30XW heat units with option 150. Please
refer to chapter 9.2.
10.3 - Dimensions, clearances, units with option 5
and 6
The dimensions and clearances are the same as for 30XW
units. Please refer to chapter 3.

* The operating range with evaporator leaving temperatures above 3°C is
permitted, but the performances are not optimised.
** For lower condenser temperatures a water flow control valve must be installed
at the condenser (two-way or three-way). Please refer to option 152 to ensure
the correct condensing temperature.
*** Please refer to chapter 10.5 for the minimum recommended evaporator glycol
flow rate.
**** Depends on the conditions at the evaporator and the load conditions.
Note:
Ambient temperatures: During storage and transport of the 30XW units
(including by container) the minimum and maximum permissible temperatures are
-20°C and 72°C (and 65°C for option 200).
