For operation from 0°C to -20°C, the unit must be equipped withoption 28 (winter operation). For both options, the unit must either be equipped with the evaporatorfrost protection option (for units without hydronic module option), or the evaporator and hydronicmodule frost protection option (for units with hydronic module option), or the water loop must beprotected 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, minimumand maximum ambient temperatures to respect are -20°C and +52°C. These temperature limitsshall be considered in case of container shipment.Operating range 30RBM 160-520 units-30-20-10010203040504 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 214852Charge partielleCharge partielle avec l’Option 16Options 28B-28C pour taille 160Options 28B- 28COption 28Option 231Entering air temperature, °CWater type exchanger leaving water temperature (°C)Operating range 30RBP 160-520 unitsEntering air temperature, °CWater type exchanger leaving water temperature (°C)- 30- 20- 10010203040504 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 2148 Part loadOption 231NOTES- The evaporator is protected against frost down to -20 °C (with frost protection option 41 or option42A 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 electroniccatalogue.Legend30RBM or 30RBP standard unit operating rangeOperating 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 °Coutside 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 below0°C for 30RBP, the unit must either be equipped with the evaporator frost protection option (for unitswithout hydronic module option), or the evaporator and hydronic module frost protection option (forunits with hydronic module option), or the water loop must be protected by the installer by adding anantifreeze solution.NOTE:Units equipped with speed regulatorsIf the air temperature is below -10°C and the unit has beende-energized for more than 4 hours, it is necessary to waittwo hours after the unit has been switched on again to allowthe regulator to warm up.Pure water operating range.For operation with brine solution, see "Brine option (Options5B and 6B)"Option 231Option 231Partial loadOptions 28B-28C for size 160Options 28B-28COption 28Partial load with Option 16Partial load
