* If the unit is operated for long periods of time out of
temperature or operational humidity range, safety
devices may cause the unit to not operate, and water
may leak from the unit due to dew condensation.
2-3 OPTIMUM OPERATION
• Do not operate the unit in Bypass mode when
the room air is heated in winter or when the
outside temperature is 25°C or higher.
This may cause condensation to form on the main
unit or on the indoor air outlet.
• Do not install the remote control where the
indoor temperature and humidity, respectively,
is out of the range of 0-35°C and RH 40-80%.
This may cause malfunction.
• Do not change operations suddenly.
It can result not only in malfunction but also failure
of switches and relays in the remote control.
• Clean the air filter frequently.
If the unit is used with a clogged air filter, it may
lead to lower operation efficiency and failure.
Refer to Page 6 and 7
• Keep the indoor unit and the remote control at
least 1 m away from televisions, radios, stereos,
and other similar equipment.
This may cause distorted picture or noise.
• Turn off the main power supply when it is not
used for long periods of time.
When the main power switch is turned on, some
watts of electricity is being consumed even if the
system is not operating.
• Do not install the remote controller where direct
sunlight may fall on it.
This may cause discoloration or deformation.
