Safety precautions
Electrical connection diagram
located on the panels of the
indoor and outdoor units.
•All wiring must be properly
arranged to ensure that the
control board cover can close
properly. If the control board
cover is not closed properly, it
can lead to corrosion and cause
the connection points on the
terminal to heat up, catch fire, or
cause electrical shock.
•If connecting power to fixed
wiring, an all-pole disconnection
device which has at least 3mm
clearances in all poles, and
have a leakage current that
may exceed 10mA, the residual
current device (RCD) having
a rated residual operating
current not exceeding 30mA,
and disconnection must be
incorporated in the fixed wiring
in accordance with the wiring
rules.
Split type air conditioner / User Manual
Take note of fuse
specifications
The air conditioner's circuit board
(PCB) is designed with a fuse to

The specifications of the fuse are
printed on the circuit board, such
as:
T3.15AL/250VAC,
T5AL/250VAC, T3.15A/250VAC,
T5A/250VAC, T20A/250VAC,
T30A/250VAC,etc.
