Notes (1) - Cooling: entering evaporator water temp. 12°C; leaving evaporator water temp. 7°C; ambient air temp. 35°C (1) - Cooling: entering evaporator water temp. 12°C; leaving evaporator water temp. 7°C; ambient air temp. 35°C
  (2) - Condition: Ta 35°C - LWE 7°C ( DT = 5°C) (2) - Condition: Ta 35°C - LWE 7°C ( DT = 5°C)
  (3) - Water can be used above 5°C. Between 0°C and 5°C a 30% glycol solution (propylene or ethylene) has to be used. Between 0°C and -10°C a 40% glycol solution (propylene or ethylene) has to be used (see installation manual and information related to OPZL option) (3) - Water can be used above 5°C.
