WORKING LIMITS EVAPORATOR: 5 ÷ 18°C Range of chilled fluid outlet temperature. CONDENSER: 20 ÷ 52°C Range of water outlet temperature. 49% Maximum concentration of antifreeze solution (Ethylene or Propylene Glycol) WARNING Please contact the RC GROUP Commercial Department in case of use of other antifreeze different from the ones listed. WORKING AREA WARNING The values are indicative. For further information and limit operation conditions, please contact the RC GROUP Commercial Department. ANTIFREEZE MIXTURES EVAPORATOR HYDRAULIC CIRCUIT Machines can work with antifreeze mixtures although not necessary, because the machines do not accept outlet temperature of the liquid cooled below 4°C. The use of glycol mixture is a generic antifreeze protection, for machines not in operation during the winter season. CONDENSER HYDRAULIC CIRCUIT In case of heat exhaustion through a close hydraulic circuit on a dry cooler, is mandatory to load the circuit with antifreeze mixture. The choice of glycol percentage may be based on the following table:

Freezing point [°C] % Ethylene glycol volume % Propylene glycol volume -10 24 27 -20 36 39 -30 46 49

_______________________________________________ STORING TEMPERATURE If the machine is not installed on receipt and is stored for a long time, store it in a protected place, at temperatures ranging between -30°C and 50°C in absence of superficial condensation and direct sun light.
