Ilectrical construction should be made with specific mains circuit by the qualified personnel according
to the installation instruction5 Ilectric shoc and fire may be caused if the capacity of power supply
is not sufficient5
Huring arranging the wiring layout3 specified cables should be used as the mains line3 which accords
with the local regulations on wiring5 Gonnecting and fastening should be performed reliably to avoid
the external force of cables from transmitting to the terminals5 Mmproper connection or fastness may
lead to burning or fire accidents5
Xhere must be the ground connection according to the criterion5 Ynreliable grounding may cause
electrical shoc s5 Ho not connect the grounding line to the gas pipe3 water pipe3 lightening rod and
telephone line5
Snly copper wire can be used5 Frea er for electric lea age should be provided3 or electric shoc
may occur5
Xhe wiring of the mains line is of ] type5 Xhe power plug P should be connected to the live wire
and plug R connected to null wire while should be connected to the ground wire5 Jor the type
with auxiliary electrically heating function3 the live wire and the null wire should not be misconnected3
or the surface of electrical heating body will be electrified5 Mf the power line is damaged3 replace it
by the professional personnel of the manufacturer or service center5
Xhe power line of indoor units should be arranged according to the installation instruction of indoor
units5
Xhe electrical wiring should be out of contact with the high4temperature sections of tubing as to avoid
melting the insulating layer of cables3 which may cause accidents5
Efter connected to the terminal tier3 the tubing should be curved into be a Y4type elbow and fastened
with the pressing clip5
Gontroller wiring and refrigerant tubing can be arranged and fixed together5
Xhe machine can}t be powered on before electrical operation5 Qaintenance should be done while
the power is shut down5
