3. Operation
About the operation method, please refer to the operation manual that comes
■
with each remote controller.
3.1. Turning ON/OFF
Note:
Even if you press the ON/OFF button immediately after shutting down the operation is progress, the air conditioner will not start for about 3 minutes. This
is to prevent the internal components from being damaged.
3.2. Operation mode select
Cool/ Dry/ Fan/ Heat/ Automatic (cool/ heat)/ ventilation mode are available.
Note:
Heat and Automatic modes can not be available for cooling only units.
●
Ventilation mode: only indicated on the following condition. Wired remote
●
controller is used and LOSSNAY is connected.
Information for multi system air conditioner (Outdoor unit: MXZ series)
► Multi system air conditioner (Outdoor unit: MXZ series) can connect two or
more indoor units with one outdoor unit. According to the capacity, two or
more units can operate simultaneously.
When you try to operate two or more indoor units with one outdoor unit simulta-
•
neously, one for the cooling and the other for heating, the operation mode of the
indoor unit that operates earlier is selected. The other indoor units that will start
the operation later cannot operate, indicating an operation state in flashing.
In this case, please set all the indoor units to the same operation mode.
There might be a case that the indoor unit, which is operating in
•
mode. Cannot change over to the operating mode (COOL ↔ HEAT) and be-
comes a state of standby.
• When indoor unit starts the operation while the defrosting of outdoor unit is being
done, it takes a few minutes (max. about 15 minutes) to blow out the warm air.
• In the heating operation, though indoor unit that does not operate may get warm
or the sound of refrigerant flowing may be heard, they are not malfunction. The
reason is that the refrigerant continuously flows into it.
Automatic operation
According to a set temperature, cooling operation starts if the room temperature
■
is too hot and heating operation starts if the room temperature is too cold.
During automatic operation, if the room temperature changes and remains 2 °C, 4 °F
■
or more above the set temperature for 15 minutes, the air conditioner switches
to cooling mode. In the same way, if the room temperature remains 2 °C, 4 °F or
more below the set temperature for 15 minutes, the air conditioner switches to
heating mode.
(AUTO)
Because the room temperature is automatically adjusted in order to maintain
■
a fixed effective temperature, cooling operation is performed a few degrees
warmer and heating operation is performed a few degrees cooler than the set
room temperature once the temperature is reached (automatic energy-saving
operation).
3.3. Fan speed setting
Note:
The number of available fan speeds depends on the type of unit connected.
●
In the following cases, the actual fan speed generated by the unit will differ
●
from the speed shown the remote controller display.
1. When the unit is in “STAND BY” or “DEFROST” states.
2. When the temperature of the heat exchanger is low in the heating mode.
(e.g. immediately after heating operation starts)
3. In HEAT mode, when room temperature is higher than the temperature
setting.
4. When the unit is in DRY mode.
3.4. Airflow direction setting
Note:
During swing operation, the directional indication on the screen does not
●
change in sync with the directional vanes on the unit.
Available directions depend on the type of unit connected.
●
In the following cases, the actual air direction will differ from the direction
●
indicated on the remote controller display.
1. When the unit is in “STAND BY” or “DEFROST” states.
2. Immediately after starting heater mode (while the system is waiting for
the mode change to take effect).
3. In heat mode, when room temperature is higher than the temperature
setting.
3.5. Ventilation
For LOSSNAY combination
The following 2 patterns of operation is available.
●
• Run the ventilator together with the indoor unit.
• Run the ventilator independently.
Note (for RF thermostat):
Running the ventilator independently is not available.

5. Care and Cleaning
Following indication shows that the filter needs cleaning.
■
• Wired remote controller: “FILTER”
• RF thermostat: “Clean Filter”
Ask authorized people to clean the filter.
When resetting “FILTER” or “Clean Filter” display.
■
Resetting the indication, refer to the operation manual of each remote controller.
Note:
When 2 or more different types of indoor unit are controlled, the cleaning
●
period differs with the type of filter. When the master unit cleaning period
arrives, “FILTER” is displayed. When the filter display goes off, the cumulative time is reset. (Only for wired remote controller.)
“FILTER” or “Clean Filter” indicates the cleaning period when the air
●
conditioner was used under general indoor air conditions by criteria time.
Since the degree of dirtiness depends on the environmental conditions,
clean the filter accordingly.
The filter cleaning period cumulative time differs with the model.
●
► Cleaning the filters
• Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner,
tap the filters against a solid object to knock off dirt and dust.
• If the filters are especially dirty, wash them in lukewarm water. Take care to rinse
off any detergent thoroughly and allow the filters to dry completely before putting
them back into the unit.
Caution:
• Do not dry the filters in direct sunlight or by using a heat source, such as
an electric heater: this may warp them.
• Do not wash the filters in hot water (above 122°F), as this may warp them.
• Make sure that the air filters are always installed. Operating the unit with
out air filters can cause malfunction.
• Before you start cleaning, stop operation and turn OFF the power supply.
• Indoor units are equipped with filters to remove the dust of sucked-in air.
Clean the filters using the methods shown in the following sketches.
► Filter removal
Caution:
• In removing the filter, precautions must be taken to protect your eyes from
dust. Also, if you have to climb up on a stool to do the job, be careful not
to fall.
• When the filter is removed, do not touch the metallic parts inside the indoor unit, otherwise injury may result.

6. Trouble Shooting
Having trouble? Here is the solution. (Unit is operating normally.)
Air conditioner does not heat or cool well.
When heating operation starts, warm air does not blow from the indoor
unit soon.
During heating mode, the air conditioner stops before the set room temperature is reached.
When dry mode starts, the set temperature changes.
Clean the filter. (Airflow is reduced when the filter is dirty or clogged.)
■
Check the temperature adjustment and adjust the set temperature.
■
Make sure that there is plenty of space around the outdoor unit. Is the
■
indoor unit air intake or outlet blocked?
Has a door or window been left open?
■
Warm air does not blow until the indoor unit has sufficiently warmed
■
up.
When the outdoor temperature is low and the humidity is high, frost
■
may form on the outdoor unit. If this occurs, the outdoor unit performs
a defrosting operation. Normal operation should begin after approximately 10 minutes.
When dry mode starts, the set temperature automatically changes to
■
the optimum initial set temperature.

During cooling mode, the vanes automatically move to the horizontal
■
(down) position after 1 hour when the down (horizontal) airflow direction is selected. This is to prevent water from forming and dripping
from the vanes.
During heating mode, the vanes automatically move to the horizontal
■
airflow direction when the airflow temperature is low or during defrosting mode.
When the airflow direction is changed, the vanes move to the set po-
■
sition after detecting the base position.
These sounds can be heard when refrigerant is flowing in the air con-
■
ditioner or when the refrigerant flow is changing.
These sounds can be heard when parts rub against each due to ex-
■
pansion and contraction from temperature changes.
The indoor unit draws in air that contains gases produced from the
■
walls, carpeting, and furniture as well as odors trapped in clothing,
and then blows this air back into the room.
If the indoor temperature and the humidity are high, this condition
■
may occur when operation starts.
During defrosting mode, cool airflow may blow down and appear like
■
a mist.
During cooling mode, water may form and drip from the cool pipes
■
and joints.
