6.1 Maintenance After the Unit Has
Been Shut Down for a Long
Period
When the fuse melts, do not use any
unspecified fuses or other wires to replace the
original fuse. The use of electrical wires or
copper wires may cause the unit to
malfunction or cause a fire.
Do not insert your fingers, sticks, or other
items into the air inlet or outlet. Do not remove
the fan mesh cover. When the fan rotates at a
high speed, it could cause bodily injury.
It is very dangerous to check the unit when the
fan is rotating.
Make sure you turn off the main switch before
any maintenance work begins.
Check the supporting and base structure of
the unit for any damages after a long period of
use. The unit could fall and cause personal
injury if there is any damage.
WARNING
For example, in early summer or winter.
Check for and remove all objects that could clog the
air inlets and outlets of the indoor and outdoor units.
Clean the air filter and external shell of the unit.
Please contact the installation or maintenance
personnel. The installation/operation manual of the
indoor unit includes maintenance tips and cleaning
procedures. Make sure that the clean air filter is
installed in its original position.
Turn on the main power supply 12 hours before
operating this unit to ensure that the unit runs
smoothly. The user interface is displayed once the
power is turned on.
6.2 Maintenance Before the Unit Is
Shut Down for a Long Period
The refrigerant in the air conditioner is
relatively safer and usually does not leak. If
the refrigerant leaks, and comes in contact
with an open flame, it will produce harmful
gases.
Shut down any heating devices which
produce flame, ventilate the room and
contact the agent of the unit immediately.
Do not use the air conditioner again until the
maintenance personnel has confirmed that
the refrigerant leakage has been sufficiently
resolved.
WARNING
Do not attempt to modify, dismantle, remove,
reinstall or repair this unit, as the improper
dismantling or installation may result in
electric shock or fire. Please contact an
agent.
If the refrigerant accidentally leaks, make
sure that there is no open flame around the
unit. The refrigerant itself is completely safe,
non-toxic and non-flammable, but it will
produce toxic gases when it accidentally
leaks and comes in contact with flames
generated by existing heaters, and burning
devices in the room. Request the assistance
of qualified maintenance personnel to verify
that the point of leakage has been repaired or
rectified before you restore the operations of
the unit.
WARNING
For example, at the end of winter and summer.
Run the indoor unit in the fan mode for about half a
day to dry the internal parts of the unit.
Turn off the power supply.
Clean the air filter and external shell of the unit.
Contact the installation or maintenance personnel to
clean the air filter and external shell of the indoor unit.
The installation/operation manual of the specialized
indoor unit includes maintenance tips and cleaning
procedures. Make sure that the clean air filter is
installed in its original position.
