7 Energy saving and optimum operation
Observe the following precautions to ensure the system operates properly.
▪
Adjust the room temperature properly for a comfortable environment.
▪
Adjust the evaporating temperature for refrigeration properly in the settings of
the outdoor unit.
▪
Prevent direct sunlight from entering a room during refrigeration operation.
▪
Ventilate often. Extended use requires special attention to ventilation.
▪
Keep doors and windows closed. If the doors and windows remain open, air will
flow out of your room causing a decrease in the refrigeration effect.
▪
Be careful NOT to refrigerate too much. To save energy, keep the temperature
setting at a moderate level.
▪
NEVER place objects near the air inlet or the air outlet of the unit. Doing so may
cause a reduced refrigeration effect or stop operation.
▪
Turn off the main power supply switch to the unit when the unit is not used for
longer periods of time. If the switch is on, it consumes electricity. Before
restarting the unit, turn on the main power supply switch 6 hours before
operation to ensure smooth running. (Refer to "Maintenance" in the indoor unit
manual.)
