Outdoor Unit •To protect compressor from reverse rotation when there is a instantaneous power failure. 60 Secs. Forced Operation Control •Once the compressor is activated, it does not stop within the first 60 secs. However, it stops immediately with remote control stop signal. Overload Protector •2-Stage OLP to protect the compressor. Overload Protector will trip when – Temperature of compressor increases to 120°C. – High temperature or high current flows to compressor. (Refer circuit diagram for OLP characteristic) Compressor Reverse Rotation Protection Control Outdoor Fan Operation Control •Temperature Fuse. 5 CS-E719K CU-E7 19K / CS-E919K CU-E9 19K / CS-E1219K CU-E1219 K
