10.1 Precautions for maintenance and service

FHA-A(9)
Split system air conditioner
4P708119-1 – 2022.11
NOTICE
Maintenance MUST be done by an authorised installer or service agent.
We recommend performing maintenance at least once a year. However, applicable
legislation might require shorter maintenance intervals.
CAUTION: Pay attention to the fan!
It is dangerous to inspect the unit while the fan is running.
Make 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
and the unit exterior.
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.
DANGER: RISK OF ELECTROCUTION
To clean the air conditioner or air filter, be sure to stop operation and turn all power
supplies OFF. Otherwise, an electrical shock and injury may result.
WARNING
Be careful with ladders when working in high places.
