(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
with the water exchanger frost protection option (for units without hydraulic
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.

Notes:
1. Water type heat exchanger ∆T = 5K.
2. 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.
3. The heat pump must be equipped with a coil defrost and condensate evacuation
kit (option 252) for outdoor temperatures < 0 °C.
4. These ranges are guidelines only. Verify the operating range with the electronic
catalogue.
