(1) For applications requiring operation below 8°C, contact your Ciat retailer 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 your Ciat retailer to select a unit using the electronic catalogue.
(4) For operation from 0°C to -20°C, the unit must be equipped with the High
seasonal performance option (variable-speed fans) or Winter operation option
(down to -20°C).
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
option) or the water exchanger 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) Partial load operation authorised below -10°C and above 44°C for standard LD
units and outdoor air temperature of 48°C for LD units with the nominal
High performance or High outdoor temperature option.
Ambient temperatures during shutdown: LD units must be stored and
transported at ambient temperatures between -20°C and +51°C. These
temperature limits shall be considered in case of container shipment.

1. Water type heat exchanger ∆T = 5K
2. The water exchanger is protected against freezing down to -20°C (with the Water exchanger frost protection option or Hydraulic module (if present) and water exchanger
frost protection option or loop protected by an antifreeze solution for outdoor temperatures of less than 0°C)
3. Operating ranges are guidelines only. The operating range must be checked with the Selection software.
