TAKE NOTE OF FUSE SPECIFICATIONS
• The air conditioner’s circuit board (PCB) is designed with a fuse to provide over-current protection.
Thespeci�cationsofthefuseareprintedonthecircuitboard,suchas:Indoorunit:T3.15AL/250VAC,
T5AL/250VAC,T3.15A/250VAC,T5A/250VAC,etc.Outdoorunit:T20A/250VAC(<=18000Btu/hunits),
T30A/250VAC(>18000Btu/hunits).
NOTE:
For the units with R32 or R290 refrigerant , only the blast-proof ceramic fuse can be used.
