9. APPENDIX
■ Care and Cleaning
WARNING
● For safety, be sure to turn the air conditioner off
and also to disconnect the power before cleaning or
maintenance.
● Do not pour water on the indoor unit to clean it. This will
damage the internal components and cause an electric
shock hazard.
Maintenance interval
The maintenance of the units should be carried out before the
heating period, to ensure correct functioning of the air curtain.
The fans or motors are low maintenance. All motors are long-
term lubricated and do not need special maintenance. Only
check that the fans run freely and are securely fixed.
Cleaning interval
The cleaning of the inlet grilles depends on the contamination
of the unit. It is recommended to clean it every 3 to 6 weeks.
CAUTION
● Never use solvents or harsh chemicals when cleaning
the indoor unit. Do not wipe plastic parts using very hot
water.
● Some metal edges and the fins are sharp and may
cause injury if handled improperly; be especially careful
when you clean these parts.
● The internal coil and other components of outdoor
unit must be cleaned regularly. Consult your dealer or
service center.
Casing
External staining on the unit has no impact on the functioning of
the air curtain. For esthetical reasons we recommend to clean
the casing with a damp cloth an a mild cleaning detergent.
Inlet grille (filter)
The units are designed for easy cleaning and servicing. It is not
necessary to disassemble the unit to clean the inlet grille. All
dust can be removed with a hoover and a brush. A damp cloth
can also be used for cleaning.
Let the inlet grille dry before restarting the unit.
Heat exchanger
To open the inspection cover, remove the inlet grille first by
opening the clip fixings with a flat-tip screw driver. Security
ropes prevent the grille from falling down. The inspection cover
is fixed with a security screw that can only be removed after the
inlet grille has been detached. The cover is attached with clip
fixings which can be opened with a flat-tip screw driver.
The heat exchanger must be cleaned with a hoover and a
brush behind the inlet grille.
Electrical units should only be cleaned on the outside. The
inside and the controls of the air curtain must be checked by an
authorised electrician, if necessary.
CAUTION
● Certain metal edges and the condenser fins are sharp
and may cause injury if handled improperly; special
care should be taken when you clean these parts.
● Periodically check the outdoor unit to see if the air
outlet or air intake is clogged with dirt or soot.
● The internal coil and other components must also be
cleaned periodically. Consult your dealer or service
center.
Care: After a prolonged idle period
Check the indoor and outdoor unit air intakes and outlets for
blockage; if there is a blockage, remove it.
Care: Before a prolonged idle period
Operate the fan for half a day to dry out the inside.
●
Disconnect the power supply and also turn off the circuit
●
breaker.
Clean the air filter and replace it in its original position.
●
Outdoor unit internal components must be checked and
●

service.
