Practical and Useful Information

3

Do not overcool your room. This may cause
health issues, and also it causes excessive
power consumption.

Prevent direct sunlight entering the room and
keep the blinds and curtains closed when the air
conditioner is operated.

Ensure that the room temperature and air flow
is distributed homogeneously inside the room by
adjusting the directions of the vertical and hori­zontal flaps of your air conditioner.

Using air curtains on wide and large areas that
the doors are kept open all the time, for example
in cafeterias, patisseries etc., will allow using
your air conditioner more efficiently by reducing
the electric consumption. Then, the room shall
reach the desired temperature more quickly.

Keep all doors and windows closed whenever
possible to keep the cool air inside the room.

Clean the air filters regularly. Blockage in the air
filter decreases air flow, cooling and dehumidifi­cation. If you do not clean air filters regularly,
cooling capacity will be lowered and some of the
energy you use will be wasted.

Ventilate the room by opening the windows as
possible, since the windows are kept closed
during the operation of your air conditioner.

If you will not use air conditioner for a long time,
operate it in the fan position for 2 to 3 hours; this
will remove the humidity inside the air condi­tioner. Then turn the A/C off with the fuse.

What to do for Comfortable Use and Energy Saving?

5

1. Make sure that the capacity of your air condi-

tioner is proper for your space.

2. An air conditioner with cooling capacity lower

than the required capacity for the space will not
provide efficient cooling; and it shall be forced to
operate the compressor continuously and energy
consumption will be increased.

3. An air conditioner with cooling capacity higher

than the required capacity for the space will cool
the room too quickly; and it turn the compressor
on and off frequently. This will increase the energy
consumption of your air conditioner. The room
will be over-cooled and this will cause discomfort
instead of comfort. Also, noise in the room
smaller with respect to the capacity of the air
conditioner will disturb you as the air conditioners
with higher cooling capacity have higher noise
levels.

4. The heat insulation of the room that you used the

air conditioner will increase your comfort and de­crease the energy consumption; thus proper in­sulation of the heat loss gain points of the room
is important. Moreover, the doors and windows
of the room shall always be closed during the op­eration of the air conditioner. If the doors shall be
kept open (as in shops or stores), use equipment
that prevent hot or cold air flow from the outside
as air curtains.

5. Using blinds, curtains or shades at the hours that

the sunlight directly enters the room may prevent
increase in your energy consumption for cooling.

6. Protecting the outer unit from direct sunlight with

a tent or canopy etc. (without preventing air flow
for the outer unit) when the outer unit is exposed
to direct sunlight may prevent increase in your
energy consumption for cooling.

7. It is important to follow placement guidelines for

the inner and outer units during installation. It is
especially important that there are no factors to
prevent air flow in front of the air inlet/outlet ducts
and blowing vents.

8. Adjusting your air conditioner to lower tempera­ture setting than you need shall increase your en­ergy consumption besides decreasing your
comfort level. You may use your air conditioner
with higher temperature settings as per your
needs instead of the lowest temperature setting.

9. Clean the dust prevention filters of your air con­ditioner regularly. As the blockage of the filters
over time may prevent air flow, it will prevent you
from obtaining the best performance from your
air conditioner. This will also increase your energy
consumption as it will constrain your air condi­tioner.

10. Cleaning of the heat exchanger elements on the

inner and outer units of the air conditioner is very
important. When the heat exchanger elements
get dirty, your air conditioner will operate more
to provide the required cooing/heating, thus
your energy consumption will be increased.
Therefore, we advise you to have your air con­ditioner maintained at least once a year. (Annual
maintenance is out of warranty coverage.)

11. You may lower your energy consumption by

using the programming function of air condi­tioner. You may set the air conditioner to shut­down when you will not use the room, and to
re-open when you will use the room.

12. We advise you to set the air directing flaps so

that they will not disturb the occupants of the
room.
