5. AIR CLEANSING FILTERS (SPX-CFH15)
• When installing the air cleansing filters, remove the air filters and attach
them onto the hooks of the front cover frame.
• The cooling capacity is slightly weakened and the cooling speed becomes
slower when the air cleansing filters are used. So, set the fan speed to
"HIGH" when using it in this condition.
• The air cleansing filters can be used for 2 years.
INFORMATION
CAPABILITIES
Heating Capability
• This room air conditioner utilizes a heat pump system that absorbs
exterior heat and brings it into a room to be heated. As the ambient
temperature gets lower, heating capability will also lower. In such a
situation, the PAM and inverter work to increase compressor rpm to keep
the unit's heating capability from decreasing. If the unit's heating
performance is still unsatisfactory, other heating appliances should be
used to augment this unit's performance.
• The air conditioner is designed to heat an entire room so that it may take some time before you feel warm. Timer
operation is recommended for effective preheating ahead of the desired time.
Cooling and Dehumidifying Capabilities
• If the heat present in a room exceeds the unit's cooling capacity (for example, if there are many people in the room
or other heating appliances are used), the preset room temperature may not be reached.
VARIOUS FUNCTIONS
• When fan speed, room temperature are set with the remote controller before starting manual operation and
the buttons are released, the indication of settings will go off in 10 seconds and only the operation mode will
be displayed.
• Pressing the button while the unit is in operation will let the protective circuit work so that the unit will
not operate for approximately 3 minutes.
• During heating operation, the indoor unit's color indicator lamp may flash with no air emitted for a while.
• If you feel cold wind during warming operation with the
quieter after the room is heated, use of
• With the (SILENT) setting, the unit's cooling capability will lower slightly.
TIMER PROGRAMMING/SLEEP TIMER OPERATION
• When the timer has been programmed, the unit will not operate even if the set time is reached unless the unit
receives a signal from the remote controller. Confirm that timer programming is complete (beep) and the
TIMER lamp of the indoor unit lights.
• If the (SLEEP) button is pressed while the ON/OFF timer is programmed, the sleep timer takes priority.
• During sleep timer operation, the fan speed sets to
