Periodical Maintenance - Lennox Compact Pro Installation Operating & Maintenance Manual

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
Department
