Optimum Operation; Maintenance (For Service Personnel) - Daikin FFQ25BV1B Operation Manual

7. OPTIMUM OPERATION

Observe the following precautions to ensure the
system operates.
• Adjust the room temperature properly for a com-
fortable environment. Avoid excessive heating or
cooling.
• Prevent direct sunlight from entering a room dur-
ing cooling operation by using curtains or blinds.
• Ventilate the room regularly.
Using the unit for long periods of time requires
attentive ventilation of the room.
• Do not place items that might be damaged by
water under the indoor unit.
Water may condensate and drip if the humidity
reaches 80% or if the drain exit gets clogged.
• Keep doors and windows closed. If the doors and
windows remain open, room air will flow out and
cause to decrease the effect of cooling and heat-
ing.
• Do not place other heaters directly below the
indoor unit.
They may deform due to the heat.
• Never place objects near the air inlet and the air
outlet of the unit. It may cause deterioration in the
effect or stop in the operation.
• Turn off the main power supply switch when it is
not used for long periods of time. When the main
power switch is turned on, some watts of electric-
ity is being used even if the system is not operat-
ing. Turn off the main power supply switch for
saving energy. When reoperating, turn on the
main power supply switch 6hours before opera-
tion for smooth running (Refer to MAINTE-
NANCE).
• When the display shows "
CLEAN AIR FILTER), ask a qualified service per-
son to clean the filters (Refer to MAINTE-
NANCE).
• Fully use the function of air flow direction adjust.
Cold air gathers on the floor, and warm air gath-
ers in the ceiling.
Set the air flow direction parallel during cooling or
dry operation, and set it downwards during heat-
ing operation.
Do not let the air blow directly to a person.
• It takes time for the room temperature to reach
the set temperature.
We recommend starting the operation in advance
using timer operation.
