• This air conditioning system contains refrigerant under pressure, rotating
parts and electrical connection which may be dangerous and can cause
injury. Installation and maintenance of this air conditioning system should
only be carried out by trained and qualified personnel.
• After unpacking, please check the unit carefully for possible damage.
• Before undertaking any work on the unit, make sure that the power supply
has been disconnected.

The drain pipe of indoor unit must be heat insulated, or it will condense dew,
as well as the connections of the indoor unit.
Hard PVC binder must be used for pipe connection, and make sure there is no
leakage.
With the connection part to the indoor unit, please be noted not to impose
pressure on the side of indoor unit pipes.
When the declivity of the drain pipe downwards is over 1/100, there should not
be any winding.

NORMAL FUNCTION OF THE AIR CONDITIONER
PROTECTION FUNCTION
Auto Restart Function
The following symptoms do not indicate air conditioner malfunction.
•
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.
1. The system does not operate
•
The system does not restart immediately
after the ON/OFF button is pressed.
ANTI-ICE and ANTI-OVERHEAT
•
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.
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.
•
The system does not restart immediately when
TEMPERATURE SETTING changed.
Low Voltage
•
The feature is used to protect against any damage to the unit caused by fluctuation 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.
If the OPERATION lamp lights, the system is in normal condition.
If the timer light is flashing 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.
Filter Care and Filter Alarm
•
•
Replace Air Purifying filter if fitted.
•
The system does not start immediately after the power supply is turned on.
Wait one minute until the microcomputer is prepared for operation.
The filters should be cleaned regularly, i.e, once a month, or more frequently depending on
conditions. The control is equipped with a filter alarm; After a certain numbers of hours of
operation, flashing lights will indicate that it is time to clean the filter. The alarm is reset by
pressing the filter button or the transmitter.
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 qualified service person familiar with the unit.
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.
Maintenance Operations
Recommended Frequency
•
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.
Air filter
Clean
Every month or more often if necessary
Every month or more often if necessary
Each season before start up*
Unit casing
Clean
Drain pan and evacuation piping
Indoor/outdoor coils
Compressor
Clean and check for obstructions
1.2 Noise of air conditioners
Clean
Each season before start up*
•
A continuous flow “Shuh” sound is heard when the systems is in COOLING
or DEFROST OPERATION. This is the sound of refrigerant
gas flowing through both indoor and outdoor units.
No need
* This operation must be carried out by qualified personnel only.
•
A “Shuh” sound which is heard at the start or
immediately after operation. It may also be heard
BEFORE MAINTENANCE
at the start or immediately after a DEFROST OPERATION.
This is the noise of refrigerant caused by the start and stop of the flow.
S
Turn off the main breaker or disconnect the main power supply.
Notes
•
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.
•
•
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.
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.
CLEANING THE UNIT
•
The units give off odours. The unit absorbs the smell of rooms,
furniture, cigarettes, etc., and then emits them.
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).
Not more than
40°C
EMERGENCY OPERATION
•
Units are equipped with a switch to run
emergency operation mode. Pushing the
emergency switch turns the unit on;
CLEANING THE AIR FILTER
pushing it again turns if off (toggle action).
During emergency operation, the remote
controller cannot be used and the power
LED light will flash at intervals, while the
other LED lights will indicate the operation
of the Diagnostic Codes.
EMERGENCY
OPERATION
1. Remove the air filter.
Open front grille
and pull fillter
3. Drying
Drying the air filter by hair
drying or direct sunlight.
outward front grille.
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.
2. Cleaning
4. Reinstall the air filter.
If the fillter is very dirty,
clean it with water
(approx 30°C).
Approx 30 °C

DE - COMMISSIONING DISMANTLING & DISPOSAL
This product contains refrigerant under pressure, rotating parts, and electrical connections which may be a danger and cause injury!
All work must only be carried out by competent persons using suitable protective clothing and safety precautions.
Read the Manual
Risk of electric shock
Unit is remotely controlled and
may start without warning
1. Isolate all sources of electrical supply to the unit including any control system supplies switched by the unit. Ensure that all points of electrical and gas isolation are secured in the OFF position. The supply
cables and gas pipework may then be disconnected and removed. For points of connection refer to unit installation instructions.
2. Remove all refrigerant from each system of the unit into a suitable container using a refrigerant reclaim or recovery unit. This refrigerant may then be reused, if appropriate, or returned to the manufacturer
for disposal. Under No circumstances should refrigerant be vented to atmosphere. Where appropriate, drain the refrigerant oil from each system into a suitable container and dispose of according to
local laws and regulations governing disposal of oily wastes.
3. Packaged unit can generally be removed in one piece after disconnection as above. Any fixing down bolts should be removed and then unit lifted from position using the points provided and equipment of
adequate lifting capacity. Reference MUST be made to the unit installation instructions for unit weight and correct methods of lifting. Note that any residual or spilt refrigerant oil should be mopped up and
disposed of as described above.
4. After removal from position the unit parts may be disposed of according to local laws and regulations.
