●Clean the air filter every week for higher
efficiency.
●Close windows and doors while operating the
unit to prevent leakage of cooled air to save
energy.
●Draw close curtains or close glass windows
when cooling to prevent heat load from sun
light which may cause more electricity cost.
●In case of ineffective ventilation, open the
window to ventilate the room air once in a
while but not too long since cooled air will be
uselessly drained out.
●The temperature should not be set lower than
what you need. This would result to increase
energy cost.
●To distribute cool air through out the room,
adjust air flow direction as shown by the
arrows (see picture) to diffuse cool air.
