Air cleaning system, optimum comfort
and lowest consumption, correct cleaning
42PQV
Air cleaning system
Ensure that the air distribution in the room is uniform by properly
adjusting the air flow direction.
Standard air filters: they eliminate dust and lint.
Standard electrostatic filter + photocatalytic filter : this
effectively eliminates microscopic dust and cigarette smoke in
the room air.
Electrostatic filter + Active carbon filter : this is particularly
effective in eliminating odor and microscopic dust.
Correct cleaning
• Turn the unit off and switch the mains supply off.
Optimum comfort and lowest consumption
Keep room temperature at comfort levels.
Do not open doors and windows more frequently than necessary.
Use only a clean, damp and soapy cloth. Do not pour any liquids on
the unit. Do not use flammable liquids, solvents or abrasive
powders.
When cooling, avoid direct sun in the room: if possible, shut
curtains or shades.
Keep heat sources away from the unit and do not place anything
hot on it; panels may be damaged.
The remote control should only be cleaned with a dry cloth.
Do not obstruct the air intake or outlet of the unit. Obstructions will
cause a reduction of the air quantity and the conditioning effect,
resulting in unit malfunction.
Occasionally clean the area around the outdoor (leaves etc.) to
avoid reduced air circulation.

Standard filter cleaning
Cleaning unit coil:
It is recommended to clean the coil at least at the beginning of each
cooling season or when necessary; turn the unit off first.
• Use a vacuum cleaner or a long-bristle brush to avoid damage to
the coil fins.
• Watch the fin edges to avoid injury.
• Damage to the fins may cause reduced coil efficiency resulting in
increased running costs. Use of flames, liquid or aerosol solvents
must be avoided. Use of these substances will cause serious
damage to the panels and electric parts.
Before a long shutdown period
Vacuum clean or rinse under running water after using a month.
Put the filters back in the correct position.
Cleaning of optional filters
Clean filters and reposition them in the unit.
• Clean photocatalytic filters by washing them under running water
(without any detergent) and regenerate them by exposing ithem
to sunlight for 6 hours.
• Clean active carbon filter by washing with neutral detergent,
rinsing and drying under sunlight.
• Replace active carbon and photocatalytic filters every two years.
• Replace electrostatic filters every three months.
• Replace active carbon filter every two years.
Keep the unit in operation for half a day in ventilation (fan only)
mode in order to dry all the internal parts.
Washing the front panel
Switch the electric mains supply off.
Take the batteries out of the controller.

• If the unit operates beyond max. temperature conditions for a
long time, system diagnostics may detect a malfunction and the
unit will not operate properly.
• If the unit operates for a long time under abnormal conditions
with extremely high humidity, condensed water may drip from the
unit.
Time delay
• If you start operation after the power is turned off, there will be a
3 minute time delay until the compressor turns on.
• When heating operation starts, hot air delivery might be delayed
due to a warm-up period.
RESET THE CIRCUIT BREAKER OR REPLACE THE FUSE WITH THE SPECIFIED
REPLACEMENT FUSE.
• Has there been a power failure?
RESTART OPERATION WHEN THE POWER IS RESTORED.
• Does the green light or the orange light flash on and off?
CALL YOUR SERVICE REPRESENTATIVE.
• Is the voltage too low?
CONFIRM THE AVAILABLE VOLTAGE.
Cooling is abnormally low:
Minimum operation time
• In normal operation, there is a minimum operation time of 5~7
minutes between the compressor turning on and turning back off.
Heating features
• If the unit starts in heating mode, there will be a preheating period
before the unit is ready to deliver warm air.
• If the outdoor temperature is low, heating capacity will be
reduced. If the room air is not warm enough during severe winter
conditions, use additional heating devices.
Defrost operation
• Is the filter blocked with dust?
