(1) For applications requiring operation at less than 8°C, contact Carrier to select a unit using the
Carrier electronic catalogue.
(2) Use of antifreeze is obligatory if the water outlet temperature is below 5°C.
(3) For applications requiring operation at a water outlet temperature exceeding 20°C, contact Carrier
to select a unit using the Carrier electronic catalogue.
(4) For applications requiring operation from 0°C to -10°C, the unit must be equipped with options
28B-28C (winter operation). For operation from 0°C to -20°C, the unit must be equipped with
option 28 (winter operation). For both options, the unit must either be equipped with the evaporator
frost protection option (for units without hydraulic module option), or the evaporator and hydraulic
module frost protection option (for units with hydraulic module option), or the water loop must be
protected against frost by the installer, using an antifreeze solution.
(5) The maximum ambient temperature allowed for machines equipped with option 231 is +40°C.
Maximum ambient temperature: if storing and transporting 30RBM/30RBP units, the minimum
and maximum ambient temperatures to be respected are -20°C and +52°C. These temperature
limits shall be considered in case of container shipment and temperatures over 52°C.

NOTES
-
The evaporator is protected against frost down to -20°C (with frost protection option 41 or option 42A
if the hydraulic module or loop is protected by an antifreeze solution for outdoor temperatures < 0°C)
-
These operating ranges are guidelines only. Verify the operating range with the Carrier electronic
catalogue.
Key
30RBM or 30RBP standard unit operating range
Operating range for 30RBM unit equipped with options 28, 28B and 28C (winter operation).
Options 28B-28C (with two-speed lead fan for each circuit) allows operation down to -10 °C
outside temperature.
Extension of the operating range, 30RBM unit equipped with option 28. Option 28 (with variable-
speed lead fan for each circuit) allows operation down to -20°C outside temperature.
In addition to the options 28, 28B or 28C for 30RBM units, or for operation at an air temperature below
0°C for 30RBP, the unit must either be equipped with the evaporator frost protection option (for units
without hydraulic module option), or the evaporator and hydraulic module frost protection option (for
units with hydraulic module option), or the water loop must be protected by the installer by adding an
antifreeze solution.
NOTE:
Units equipped with variable speed drives
If the outside temperature is below -10°C and the unit has
been switched off for more than 4 hours, it is necessary to
wait two hours after the unit has been switched on again to
allow the variable drive to warm up.
Pure water operating range.
For operation with brine solution, see "Brine option (Options
5B and 6B)"
