3. Before Operation
Power is turned on. Apply power to the outdoor unit(s) at least 12 hours prior to operation of the
system for preheating of the compressor oil. Make sure that the outdoor unit is not covered with
snow or ice. If it is, remove it by using hot water that is approximately 122
o
F (50
o
C).
If the water temperature is higher than 122
o
F (50
o
C), it will cause damage to plastic parts.
● Turn OFF the main power switch when the system is stopped for a long period of time.
If the main switch is not turned OFF, electricity is consumed because the oil heater is always energized
during compressor stopping.
● When the system is started after a shutdown longer than approximately 3 months, it is recommended that
the system be checked by your service contractor.
NOTICE
3.2 Efcient Use of Indoor Unit
● Do not leave a window or a door open.
The operating efciency is decreased.
It may cause condensation of the indoor unit. Ventilate a room sufciently.
● Attach a curtain or a blind to a window.
Blocking direct sunlight into a room will increase efciency.
● Do not use heat equipment during the cooling operation as much as possible.
The cooling efciency is decreased. It may cause condensation and dew drops.
● Use a circulator if warm air stays around the ceiling.
Comfort increases. Contact your distributor for details for using a circulator.
● Turn OFF the main power source if the indoor unit is not to be used for a long period.
The standby electricity charges will have to be paid even if the indoor unit is unused.
