Before Operation

2.1 Efficient Use of Indoor Unit
● Do not leave a window or a door open.
The operating efficiency will be decreased.
It may cause dew condensation of the indoor unit. (Ventilate a room sufficiently too.)
● Attach a curtain or a blind to a window.
Direct sunlight is prevented and the cooling efficiency will be increased.
● Do not use heating appliances during the cooling operation as possible.
The cooling efficiency will be decreased. It may cause dew condensation and dropping dew.
● Use a circulator if warm air stays around ceiling.
The comfortability will be increased. Contact your distributor for the detail.
● Turn OFF the main power source if the indoor unit is not used for a long time.
If not, the standby electricity charges will have to be paid even if the indoor unit is unused.
2.2 Efficient Use of Cooling and Heating
(1) Air Flow Direction
The appropriate air outlet angle is approx. 10
If the cooling is not sufficient, change the air flow
direction.

Air Outlet Angle
(Refer to the item 4.3 on the operation manual
of PC-ARF1.)
(2) Air Flow Volume
"MED" should be usually used. If the air flow volume
is set as "HIGH", the air flow will be spread wider than
"MED".
(3) Temperature
The recommended set temperature is 27 to 29
If the cooling is not sufficient, set the lower
temperature.
< About SET FREE Series >
When the number of indoor unit or the operating mode is changed, the air outlet temperature may be
changed and the indoor temperature is changed. In this case, set as follows.
● During Cooling: Lower slightly the temperature setting.
● During Heating: Raise slightly the temperature setting.
