OPERATION
Observe the following precautions to ensure the system operates
properly.
■
Fully use the function of air flow direction adjustment.
As cold air gathers on the floor and warm air gathers against the
ceiling, it is recommended to set the air flow direction during
cooling or dry operation parallel to the ceiling and to set it
downwards during heating operation.
Beware on the other hand, to avoid direct air flow to room
inhabitants.
■
Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling.
Notice that it may take some time for the room temperature to
reach the set temperature. Consider therefore to take advantage
of the timer setting possibilities.
■
Prevent direct sunlight from entering a room during 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 operate the air conditioner when using a room
fumigation-type insecticide.
Failure to observe this could cause the chemicals to become
deposited in the unit, which could endanger the health of those
who are hypersensitive to chemicals.
■
Keep doors and windows closed. If the doors and windows
remain open, room air will flow out and decrease the effect of
cooling and heating.
■
Never place objects near the air inlet and the air outlet of the
unit. It may retard effectiveness or cause operation to stop.
■
Turn off the main power supply switch when not using for long
periods of time. Electricity is consumed as long as the switch is
on. Turn off the main power supply switch in order to save
energy. Turn on the main power supply switch 6 hours before
restarting operation in order to ensure smooth operation. (Refer

under
Do not use the air conditioner for other purposes.
In order to avoid any quality deterioration, do not use the
unit for cooling precision instruments, food, plants, animals
or works of art.
CAUTION
■
Only a qualified service person is allowed to perform
maintenance.
■
Before obtaining access to terminal devices, all power
supply circuits must be interrupted.
■
To clean the air conditioner or air filter, be sure to stop
operation and turn all power supplies off.
Otherwise, an electric shock and injury may result.
■
Do not wash the air conditioner with water.
Doing so may result in an electric shock.
■
Be careful with scaffoldings.
Caution must be exercised when working in high
places.
■
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and cause
injury.
■
Do not touch the heat exchanger fins.
The fins are sharp and could result in cutting injuries.
■
When cleaning the heat exchanger, be sure to remove
the control box, fan motor, drain pump and float
switch. Water or detergent may deteriorate the
insulation of electronic components and result in burn-
out of these components.
Caution for drain socket
Do not remove the drain pipe plug. Water might leak out.
The drain outlet is only used to discharge water if the drain
pump is not used or before maintenance. Gently put in and
out the drain plug. Excessive force may deform the drain
socket of the drain pan.
■
Pulling out the plug
Do not wiggle the plug up and down
■
