OPERATING TIPS

Operation and Performance
About priority state and standby state
● Multiple indoor units can be connected within the same system. De-
pending on the system, choice of operating mode are limited.
Cooling priority state:
When the other indoor units within the same system operate in cooling
or dry mode, heating cannot be selected at the same time.
Heating priority state:
When the other indoor units within the same system operate in heating
mode, cooling and dry mode cannot be selected at the same time.
Standby state:
The standby state activates when 2 or more indoor units start up at the
same time in different mode. Any indoor unit other than priority mode
will wait in standby state until priority mode changes (operation starts
as soon as priority is switched).
At this time, the OPERATION indicator lamp (green) lights up and the
TIMER indicator lamp (orange) fl ashes.
Low ambient cooling
● When the outdoor temperature drops, the outdoor unit's fans may
switch to Low Speed, or one of the fans may stop intermittently.
Heating performance
● Heating mode operates on the heat-pump principle, absorbing heat
from outdoor air and transferring that heat indoors. As a result, the
operating performance is reduced as outdoor air temperature drops.
If you feel that insuffi cient heating performance is being produced, we
recommend you use this air conditioner in conjunction with another
type of heating appliance.
● Heating mode heat your entire room by recirculating air throughout the
room, with the result that some time may be required after fi rst starting
the air conditioner until the room is heated.
Microcomputer-controlled automatic defrosting
● When using the Heating mode under conditions of low outdoor air
temperature high humidity, frost may form on the outdoor unit, result-
ing in reduced operating performance. In order to prevent this kind of
reduced performance, this unit is equipped with a Microcomputer-con-
trolled automatic defrosting function. If frost forms, the air conditioner
will temporarily stop, and the defrosting circuit will operate briefl y (for
about 4 to 15 minutes).
During Automatic Defrosting operation, the OPERATION indicator
lamp (green) will fl ash.
Oil recovery operation
● Periodically, the oil recovery operation is performed in order to return
compressor oil to the outdoor unit. During oil recovery operation, the
OPERATION indicator lamp (green) will fl ash (for about 10 minutes).
