(1) For an application requiring start-up at less than 8°C, contact the manufacturer to select a unit using the manufacturer's electronic catalogue.
(2) The use of antifreeze protection is required 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 manufacturer's electronic catalogue.
(4) For operation at an ambient temperature of 0°C down to -20°C (cooling mode), the unit must be a ILD ST unit equipped with option "Winter operation" or an ILD
HE unit.
(5) For operation at an ambient temperature of 0°C down to -10°C (heating mode), the unit must be equipped with the "Coil defrost heater" option
(6) For operation at an ambient temperature below 0°C (cooling mode and heating mode), the unit must either be equipped with the water heat exchanger frost
protection option (for units without hydraulic module option) or the water heat 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.
(7) The maximum allowable ambient temperature for machines equipped with the Power factor correction option is +40°C
(8) Operation with low-temperature glycol/water mix only for ILDHE 650/900/1000/1150
Maximum ambient temperature: AQUACIAT
POWER
ILD ST / ILD HE 602-2000 units must be stored and transported at ambient temperatures of between -20°C and
+52°C. These temperature limits shall be considered in case of container shipment.
