service
CAUTION: Pay attention to the fan!
It is dangerous to inspect the unit while the fan is running.
Be sure to turn off the main switch before executing any
maintenance task.
CAUTION
Do NOT insert fingers, rods or other objects into the air
inlet or outlet. When the fan is rotating at high speed, it will
cause injury.
NOTICE
Never inspect or service the unit by yourself. Ask a
qualified service person to perform this work. However, as
end user, you may clean the air filter, suction grille, air
outlet and outside panels.
WARNING
Never replace a fuse with a fuse of a wrong ampere ratings
or other wires when a fuse blows out. Use of wire or
copper wire may cause the unit to break down or cause a
fire.
CAUTION
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in injury.
NOTICE
Do NOT wipe the controller operation panel with benzine,
thinner, chemical dust cloth, etc. The panel may get
discoloured or the coating peeled off. If it is heavily dirty,
soak a cloth in water-diluted neutral detergent, squeeze it
well and wipe the panel clean. Wipe it with another dry
cloth.
CAUTION
Before accessing terminal devices, make sure to interrupt
all power supply.
NOTICE
When cleaning the heat exchanger, make sure to remove
the switch box, fan motor, drain pump and float switch.
Water or detergent might deteriorate the insulation of
electronic components and result in burnout of these
components.
