(1) Total unit flow rate and pressure drop are given
Caution: Minimum flow rates may only be used with brine solutions after reprogramming unit parameters.
(2) Table shows minimum water / brine volume of system
(3) Maximum ambient air temperature depends on coding:
Standard/Low Noise Units: ISPESL 43°C, SDM 40°C, TUV 40°C, SAQ 38°C, UDT 43°C
High Temperature units: ISPESL 45°C, SDM 43°C
