Ref 2 operation at ambient temperatures 10 c requires option 99a fan speed modulation or option 42 speedtroll 54
Ref 3 units with the reduced noise configuration can increase the sound level in this area 54
Ref 4 partial load operation operation at full load may require option 142a b c high ambient temperature kit 54
The above graphic represents a guideline about the operating limits of the range please refer to the latest unit selection software css for real operating limits working conditions for each size 54
The following tables indicate the minimum and maximum water flow allowed for each model the minimum flow indicated correspond to the minimum flow allowed at minimum load for the unit it is not intended as minimum flow allowed for unit full load operation for minimum flow allowed maximum deltat in full load operation refer to selection software the below values are referred to pure water in case of glycol mixture contact factory note the performances are certified at standard conditions and with the unit operating with the nominal water flow 54
The minimum and maximum allowed δt at full load conditioins are respectively 2 5 c and 10 c contact factory in case lower or higher δt are required minimum and maximum water side heat exchanger flows are to be respected withing the δt range above 54
The presence of glycol in the water system will affect unit performances refer to the selection software for details all machine protection systems such as antifreeze and low pressure protection will need to be set in accordance to the type and percentage of the glycol and plant requirements 54
