(1)  For an application requiring start-up at less than 8 °C, contact the manufacturer 
to select a unit using the electronic catalogue.
(2)  The  use  of  antifreeze  is  mandatory  if  the  water  outlet  temperature  is 
below 5 °C.
(3)  For applications requiring operation above a water outlet temperature of 20 °C, 
contact the manufacturer to select a unit using the electronic catalogue.
(4)  For operation at an ambient temperature below 0 °C, the unit must be equipped

module) or the hydraulic module and water exchanger frost protection option 
(for units with hydraulic module) or the water loop must be protected against 
frost by the installer with an antifreeze solution.
(5)  Partial load operation permitted below an outdoor temperature of -10 °C and 
above 46 °C. Contact the manufacturer to select a unit using the electronic
catalogue.
Ambient temperatures during shutdown: The storage and transportation
of 30RB/RBP and 30RQ/RQP units must be carried out at ambient
temperatures between -20 °C and +51 °C. These temperature limits shall
be considered in case of container shipment.

The hydraulic module and/or water type heat exchanger must be protected
against  frost  (option  41  or  42A  or  42B)  or  the  loop  must  be  protected  by  an 
antifreeze solution for outdoor temperatures < 0 °C.
The heat pump must be equipped with a coil defrost and condensate evacuation
kit (option 252) for outdoor temperatures < 0 °C.
These ranges are guidelines only. Verify the operating range with the electronic
catalogue.
Operating range at full load
Extension of the operating range, 30RQP unit: Frost protection required
(see note 2).
Potential load shedding before defrosting during the frosting cycle, depending
on the humidity conditions.
Please refer to the selection in the electronic catalogue.
Heating mode: part load at inlet air temperature between -10 and -15 °C.
Cooling mode: part load at inlet air temperature above 46 °C.
Inlet air temperature limitation at 42 °C for units with option 15LS.
