Maintenance and disposal
Warning!
• The appliance must be maintained and cleaned internally only by qualified person-
nel.
• Always disconnect the appliance from the mains supply before starting any main-
tenance work and before accessing any internal components.
Perform the various cleaning and maintenance operations at the intervals specified in the
following table.
Table II: Scheduled maintenance
Indoor unit Every month Every 4 months Every year
Clean the air filter (1) √
Clean the condensate drain pipe (1) √
Change the batteries in the
infra-red remote control (if present) √
Perform the above maintenance operations at least at the intervals specified to keep the
appliance functioning efficiently.
Maintenance intervals should obviously be adapted to the conditions of each installation,
e.g. the amount of dust in the atmosphere etc..
(1) These operations must be performed only by qualified personnel. See the relevant
“Installation Manual”.
Trouble-shooting (any subsequent maintenance must be performed
only by qualified personnel)
The air conditioner fails to start:
• The main switch is turned off. Turn the
switch ON.
• The fuses in the main switch have burned
out. Change the fuses.
• Wait three minutes. The compressor
start-up delay has not finished.
• The temperature setting is higher than the
actual room temperature in cooling mode,
or lower than it in heating mode (so the
thermostat does not request functioning).
• Check that the condensate pump (if fit-
ted) is not in alarm state and that the level
of water in the condensate bowl is not too
high.
