Optimum Operation - Daikin RZVF50 Installation Manual

■
CHARACTERISTICS OF THE PROGRAM
DRY OPERATION
• This operation lowers the humidity without
lowering the indoor temperature. The indoor
temperature when the operation button is pressed
will be the set temperature. At this time, the fan
speed and temperature are set automatically,
so the remote controller does not display the fan
speed and set temperature.
To efficiently lower the indoor temperature and
humidity, first use the COOLING OPERATION
to lower the indoor temperature, and then use
the PROGRAM DRY OPERATION. When the
indoor temperature is lowered, airfl w from the air
conditioner may stop.
• If the PROGRAM DRY OPERATION is used
when the indoor temperature is low, frost forms
the heat exchanger of the indoor unit. In this case,
the air conditioner automatically switches to the
DEFROS T OPERATION for a while.
The low fan speed or a gentle wind is used to
prevent the discharge of melt water.

conditioner operates.
• Prevent direct sunlight from the window by using
curtains or blinds during the COOLING
OPERATION.
• Keep doors and windows closed. If the doors and
windows remain open, room air will fl w out and
decrease the effect of cooling and heating.
• Never place objects near the air inlet and the air
outlet of the air conditioner. It may decrease the
effect or stop the operation.
• Set the airflow of the air discharge grille
horizontally not to obstruct the wind.
Otherwise, the wind will not come out and a
failure may result.
