OPERATION DETAILS
Please read and understand the following details regarding this air conditioner.
Operation and Performance
Heating Performance
●
This air conditioner uses a heat pump which absorbs
heat from outside air and brings it indoors. As a result, its
heating performance is reduced as the temperature of
outside air drops. If you find that insufficient room heat
is produced, we recommend that you use the air
conditioner together with other heating appliances.
●
Heat-pump type air conditioners use warm-air recircula-
tion to warm your entire room. As a result, some time
will be required after starting operation until your entire
room becomes warm.
Microcomputer-controlled Automatic
Defrosting
When outside air temperatures are low and humidity is high,
using the Heating mode may result in the creation of frost
inside the outdoor unit, lowering its heating performance.
A built-in microcomputer is used to monitor this condition
and when necessary, the defrosting mode operates, result-
ing in a temporary interruption of the Heating mode (both
indoor and outside fans will stop). About 7 to 15 minutes
will be required for normal operation to be resumed.
Temperature and Humidity Range
Permissible ranges of temperature and humidity are as
follows:
Outdoor temperature:
About 21°C to 43°C
Indoor temperature:
About 21°C to 32°C
Indoor humidity:
About 80% or less. If the unit is used for
long periods under conditions of high
humidity, water may condense on and drip
from the surface of the unit.
Outdoor temperature:
About 0°C to 21°C
Indoor temperature:
About 30°C or less
If the unit is used under higher temperature conditions
than those noted here, the automatic protection circuit may
operate, interrupting the operation. If the unit is used under
lower temperature conditions than those noted here, the heat
exchanger may freeze, causing water leakage or other
malfunction.
●
Do not use the air conditioner for any purpose other
than room cooling or room heating.
