MAINTENANCE
IMPORTANT!
NO USER SERVICEABLE PARTS ARE INSIDE THE AIR
CONDITIONER. DO NOT REMOVE ANY ACCESS PANELS OR
FIXED COVERS.
• Before cleaning the air conditioner, be sure to stop operation, and turn
the power switch off. Otherwise, an electric shock and injury may result.
• Do not wash the indoor unit with water. Doing so may result in an
electric shock. Be careful erecting scaffolding. Caution must be
exercised when working at a height.
CLEANING THE AIR FILTER(s)
• Be sure to always clean the air filter(s) before use at the beginning of
summer and winter. (Dirt and dust caught in the air filter causes a drop
in airflow, which leads to a decline in performance.)
• When using the unit in a location where dirt may easily accumulate,
clean the filter(s) more frequently. Once every 2 weeks is
recommended.
NOTE
The air filter(s) and the suction grille(s) are supplied by your dealer. Ask
your DAIKIN dealer how to clean them.
HOW TO CLEAN AIR OUTLET GRILLE
Clean with soft cloth.
When it is difficult to remove stains, use water or neutral detergent.
NOTE
• Do not use gasoline, benzene, thinner, polishing powder, liquid
insecticide. It may cause discolouring or warping.
• Do not let the indoor unit get wet. It may cause an electric shock or a
fire.
Ducted Air Conditioners
START UP AFTER A LONG STOP
Confirm the following
Check that the air inlet and outlet are not blocked. Remove any
obstacle.
Clean the air filter(s)
After cleaning the air filter, make sure to reattach it.
Turn on the main power supply switch
The display on the remote controller will be shown when the power is
turned on. To protect the unit, turn on the main power switch at least 6
hours before operation.
WHAT TO DO WHEN STOPPING THE SYSTEM FOR A LONG
PERIOD Turn on FAN OPERATION for a half day and dry the unit.
Refer to fan setting or fan speed button on pages 4 & 6 of the
installation manual.
Cut off the power supply.
• When the main power switch is turned on, some power is being used
even if the system is not operating. Turn off the main power supply
switch for saving energy.
• The display on the remote controller will vanish when the main power
switch is turned off.
Ensure the drain piping from the indoor unit is free of blockage.
During cooling operation, water should drip from the outlet of the indoor
unit's drain piping. If there is no evidence of water from the drain outlet
after several hours of cooling it may be that the drain is blocked or the
relative humidity is low. If you think the drain is blocked stop the air
conditioner and contact your installer.
SELF DIAGNOSIS
• In the unlikely event that a fault develops with the air conditioner the
microprocessor in the indoor and outdoor units will diagnose the fault
(where possible), Aunique 2 digit fault code will display on the LCD
screen. eg.E0
• If this occurs write down the fault code and then switch off the unit and
contact your installer. This code will indicate to the installer / repairer
what the problem may be.
