Note:
(1) For low-temperature applications, where the leaving water temperature is below 4° C, the anti-freezing protection switch
will stop the unit stop from running.
(2) If the temperature leaving the condenser is below 19° C,the unit will stop and give a warning
(3) Ambient temperatures: During storage and transport of the LSBLG/MCF units. Including by container) the minimum
and maximum permissible temperatures are -20° C ~ 46° C(R134a);
