Evacuation Of Condensation Water In Case Of Emergency; Periodical Maintenance - mundoclima MU-UNIC Serie Manual De Instalación. Instrucciones Para El Uso

The machine is set in the factory without correction of
the temperature.
In addition to the self-test (that can be made under any
conditions of room temperature) we recommend that you
also test the product in the various operating modes
accessible to the user (see the user manual). One
important test you should make concerns regular
evacuation of condensation water on the models with heat
pump. To check this, keep the machine running for at
least 4-5 hours in the heating mode. If the water does not
drain, there should be an "overflow" alarm.

To enable the air conditioner to work temporarily until the
service personnel arrives, you can drain the water out by
following these simple instructions:
- Grasp the rubber cap on the bottom centre of the air
conditioner behind the edge of the frame facing the wall
between your thumb and forefinger.
- Pull the rubber tube closed by the cap out by a few
centimetres.
- Remove the cap after placing a bucket or other container
underneath it (at least five litter capacity) to collect the
water (see fig. 23).
- After eliminating the malfunction the service personnel
will take care of closing the evacuation tube.

PERIODICAL MAINTENANCE

Air conditioners of this type do not require any particular
routine maintenance except:
- Cleaning or washing the room air filter when the red
led lights up (see user manual).
- Cleaning of "external air" battery, to be done as needed,
depending on the amount of dirt in the external air,
once or twice a year. To do this, you must, of course,
open the air conditioner by removing its casing and
the noise insulation on the inside.
- Cleaning can be done using a vacuum cleaner or soft
brush, taking particular care not to damage the
aluminium heat exchanger baffles. It may be necessary
to use water and detergents to remove heavily
encrusted dirt.
Note: after cleaning the battery replace the noise
insulation carefully matching the edges and gaskets
with their reference markings.
Before you leave the site of installation you should gather
up all packing material and use a damp cloth to remove
any traces of dust that may have deposited on the
machine during assembly (fig. 24).
These operations, though certainly not essential, have a
beneficial effect as they enhance the professional image
of the installer in the eyes of the client.
To prevent unnecessary calls by the user, before you leave
the site of installation it is also a good idea to:
- Explain the contents of the Instruction Manual to the user.
- Show him how to clean the filter.
- Explain when and how he should contact the Service
