En-4
Heat*
• Use to warm your room.
• When Heating mode is selected, the air conditioner will
operate at very low fan speed for about 3 to 5 minutes,
after which it will switch to the selected fan setting. This
period of time is provided to allow the indoor unit to warm
up before beginning full operation.
• When the room temperature is very low, frost may form
on the outdoor unit, and its performance may be re-
duced. In order to remove such frost, the unit will auto-
matically enter the defrost cycle from time to time. During
Automatic defrosting operation, the Heating operation
will be interrupted.
• After the start of Heating operation, it takes sometime
before the room gets warmer.
Cool
Use to cool your room.
Dry
• Use for gently cooling while dehumidifying your room.
• You cannot heat the room during Dry mode.
• During Dry mode, the unit will operate at low speed; in
order to adjust room humidity, the indoor unit’s fan may
stop from time to time. Also, the fan may operate at very
low speed when adjusting room humidity.
• The fan speed cannot be changed manually when Dry
mode has been selected.
Fan
Use to circulate the air throughout your room.
NOTES
*During Heating mode:
Set the thermostat to a temperature setting that is higher
than the current room temperature. The Heating mode will
not operate if the thermostat is set lower than the actual
room temperature.
During Cooling/Dry mode:
Set the thermostat to a temperature setting that is lower than
the current room temperature. The Cooling and Dry modes will
not operate if the thermostat is set higher than the actual room
temperature (in Cooling mode, the fan alone will operate).
During Fan mode:
You cannot use the unit to heat or cool your room.
Economy operation
At the maximum outlet, Economy operation is approximately
70 % of normal air conditioner operation for cooling and
heating.
If the room is not cooled (or heated), well during Economy
operation, select normal operation.
Fan speed
Controls the fan speed.
AUTO
HIGH
QUIET
MED
LOW
When AUTO is selected, the fan speed is automatically ad-
justed according to the operation mode.
Heating*: The fan will operate at very low speed when the
temperature of the air issued from the indoor unit
is low.
Cooling: As the room temperature approaches that of the
set temperature, the fan speed becomes slower.
Fan:
The fan runs at medium fan speed.
Auto restart
In Event of Power Interruption
• Should the power supply to the air conditioner be inter-
rupted by a power failure, the air conditioner will restart
automatically in the previously selected mode once the
power is restored.
• Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the
air conditioner to malfunction. In this event, temporarily
disconnect the power supply, reconnect it, and then use
the remote controller to resume operation.
Multiple remote controller (optional)
An additional remote controller can be added up to the
maximum of two remote controllers. Either remote controller
can control the air conditioner. However, the timer functions
cannot be used at the secondary unit.
Group control
One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same settings.
Notices
*
• During use of the Heating mode, the outdoor unit will
occasionally commence the defrost operation for brief
periods. During the defrosting operation, if the user sets
the indoor unit for heating again, the defrosting mode
will continue, and the Heating operation will begin after
completion of defrosting, with the result that some time
may be required before warm air is emitted.
*
• During use of the Heating mode, the top of the indoor
unit may become warm, but this is due to the fact that
coolant is circulated through the indoor unit even when it
is stopped; it is not a malfunction.
