(1) For applications requiring operation at less than 8°C, contact Carrier for unit selection using the
Carrier electronic catalogue.
(2) Use of antifreeze is obligatory if the leaving water temperature is below 5°C.
(3) For applications requiring operation exceeding 20°C leaving water temperature, contact Carrier
for unit selection 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 hydronic module option), or the evaporator and hydronic
module frost protection option (for units with hydronic module option), or the water loop must be
protected against frost by the installer, using an antifreeze solution.
(5) The maximum allowable ambient temperature allowed for units equipped with option 231 is +40°C.
Maximum ambient temperature: in case of 30RBM/30RBP units storage and transport, minimum
and maximum ambient temperatures to respect are -20°C and +52°C. These temperature limits
shall be considered in case of container shipment.

Option 231
-
The evaporator is protected against frost down to -20 °C (with frost protection option 41 or option
42A if the hydronic 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.
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 hydronic module option), or the evaporator and hydronic module frost protection option (for
units with hydronic module option), or the water loop must be protected by the installer by adding an
antifreeze solution.
NOTE:
Units equipped with speed regulators
If the air temperature is below -10°C and the unit has been
de-energized for more than 4 hours, it is necessary to wait
two hours after the unit has been switched on again to allow
the regulator to warm up.
Pure water operating range.
