Note:
(1) For low-temperature applications, where the leaving water temperature is below 4°C, freeze protection switch will work unit
stop.
(2) If the temperature leaving the condenser is below 19°C,the unit will stop and warning
(3) Ambient temperatures: During storage and transport of the MWSC_A-FB3 units. Including by container) the minimum
and maximum permissible temperatures is -20°C ~ 46°C(R134a);
