Air Conditioner Operations And Performance; Adjusting Air Flow Direction - EAS Electric VRV Installation And Owner's Manual

11. Air Conditioner Operations and Performance

The operating temperature range under which the unit runs stably are
given in below table.
Mode Indoor temperature
Cooling If the indoor humidity is abov e 80%, condensation
may f orm on the surf aceof the unit.
Heating
Caution
• The unit performs stably in the temperature range given in
above table. If the indoor temperature is outside the unit's
normal operating range, it may stop running and display an
error code.
To ensure the desired temperature is achieved efficiently, ensure that:
All windows and doors are closed.

 The airflow direction is adjusted to work in running mode.
The air filter is clean.
Please note how you can best save energy and achieve the best
cooling/heating effect.
Regularly clean air filters inside indoor units.

Check
regularly
Avoid too much outdoor air coming into air-conditioned spaces.

Note that outlet air is cooler or heater than set room temperature.

Avoid direct exposure to outlet air as it may be too cool or hot.

Maintain a proper air distribution. Air outlet louvers should be

used to adjust the direction of outlet airflow, as doing so might
ensure more efficient operation.

12. Adjusting Air Flow Direction

Since warmer air rises and cooler air falls, the distribution of
warmed/cooled air around a room can be improved by positioning the
unit's louvers. The louver angle can be adjusted by pressing the
[SWING] button on the remote controller.
Caution
• During heating operation, horizontal airflow will aggravate the
uneven distribution of room temperature.
• The louver direction: horizontal airflow is recommended
during cooling operation. Note the downward airflow will
cause condensation on the air outlet and louver surface.
Adjust the air direction up and down

a. Auto-swing: Press SWING for the louver to swing up and down.
b. Manual swing: Adjust the louver to improve the cooling or
heating effect.
c. When cooling adjust the louver horizontally.
d. When heating adjust the louver downward.
