EMERGENCY
OPERATION
PROTECTION FUNCTION
Auto Restart Function
• The unit will automatically restart after loss of the electrical power supply. When power is
restored; the unit operation will restart according to all parameters set before the loss of
power.
ANTI-ICE and ANTI-OVERHEAT
• This feature is used to prevent the indoor unit from freezing during cool or dry operation
and overheating in heat mode. During execution of anti-ice operation and anti-overheating,
the compressor will stop operating and the fan will continue to run until the coil temperature
reaches predetermined set points, at which time the unit will resume normal operation.
Low Voltage
• The feature is used to protect against any damage to the unit caused by fl uctuation of voltage.
If voltage is lower than the lower limit for approximately 10 seconds or longer, compressor
operation will be temporarily stopped. Normal operation will resume when the voltage returns
above the set limit for a minimum of 10 seconds. If the time elapsed is less than 3 minutes
then the compressor start up will be delayed until 3 minutes has passed.
Filter Care and Filter Alarm
• Replace Air Purifying fi lter if fi tted.
• The fi lters should be cleaned regularly, i.e, once a month, or more frequently depending on
conditions. The control is equipped with a fi lter alarm; After a certain numbers of hours of
operation, fl ashing lights will indicate that it is time to clean the fi lter. The alarm is reset by
pressing the fi lter button or the transmitter.
MAINTENANCE
The units are designed to operate for long periods of time with a minimum of maintenance.
However, the following operation must be performed regularly.
* This operation must be carried out by quali fi ed personnel only.
BEFORE MAINTENANCE
S Turn off the main breaker or disconnect the main power supply.
Notes
• Don’t spill water : There is a danger of electric shock.
• Don’t used petrol, paint thinner, benzene or polishing agents
: They may deform or scratch the unit.
CLEANING THE UNIT
Wipe the unit with a soft dry cloth only.
If the unit is very dirty, wipe it with a cloth soaked
in warm water (Not more than 40
°
C).
CLEANING THE AIR FILTER
1. Remove the air fi lter.
Open front grille
and pull
fi llter
outward front grille.
3. Drying
Drying the air fi lter by hair
drying or direct sunlight.
2. Cleaning
If the fi llter is very dirty,
clean it with water
(approx 30
° C).
4. Reinstall the air fi lter.
Approx 30
°
C
NORMAL FUNCTION OF THE AIR CONDITIONER
The following symptoms do not indicate air conditioner malfunction.
1. The system does not operate
• The system does not restart immediately
after the ON/OFF button is pressed.
If the OPERATION lamp lights, the system is
in normal condition.
The safety device operates to prevent overload of the system.
After 3 minutes, the system will turn on again automatically.
• The system does not restart immediately when
TEMPERATURE SETTING changed.
If the OPERATION lamp lights, the system is in normal condition.
If the timer light is fl ashing operation is being delayed by the safety
device. It does not restart immediately because the compressor
has been stopped and requested to start within the delay period.
A safety device operates to prevent overload of the system.
After 3 minutes, the system will turn on again automatically.
• The system does not start immediately after the power supply is turned on.
Wait one minute until the microcomputer is prepared for operation.
1.1 White mist comes out of a unit
• When humidity is high during cooling operation.
(In dusty locations or after construction work)
If the inside of an indoor unit is contaminated,
the temperature distribution inside a room may
become uneven. It is necessary to clean the inside
of the indoor unit. The unit should be cleaned by
a quali fi ed service person familiar with the unit.
• When the system is changed over to HEATING OPERATION
or after DEFROST OPERATION. Moisture generated on
the coil by the DEFROST becomes vapour and exists.
1.2 Noise of air conditioners
• A continuous fl ow “Shuh” sound is heard when the systems is in COOLING
or DEFROST OPERATION. This is the sound of refrigerant
gas fl owing through both indoor and outdoor units.
• A “Shuh” sound which is heard at the start or
immediately after operation. It may also be heard
at the start or immediately after a DEFROST OPERATION.
This is the noise of refrigerant caused by the start and stop of the fl ow.
• A “Pishi-pishi” squeaking sound is heard when the system is in
operation or just after operation. Expansion and contraction of plastic
parts caused by temperature change makes this noise.
1.3 Dust from the units
• Dust may blow out from the unit when starting after long off cycles.
Dust absorbed by the unit blows out.
• The units give off odours. The unit absorbs the smell of rooms,
furniture, cigarettes, etc., and then emits them.
EMERGENCY OPERATION
• Units are equipped with a switch to run
emergency operation mode. Pushing the
emergency switch turns the unit on;
pushing it again turns if off (toggle action).
During emergency operation, the remote
controller cannot be used and the power
LED light will fl ash at intervals, while the
other LED lights will indicate the operation
of the Diagnostic Codes.
In Emergency Operation and cooling units
the temperature will be set at 24 ° C and the fan on Auto.
Heating units will switch to auto mode at a temperature set
point of 24
°
C and the fan will run on auto mode.
• After a power failure the unit restarts automatically in the same
mode as before the failure, when power is resumed.
