1.3 System Operating Principles
* The Air Conditioning System uses both mains electrical power and solar thermal energy. The Air
Conditioning System always requires mains electrical power to operate fans and electric control
components.
* The Air Conditioning System uses solar thermal energy as an energy source to help maintain the
refrigeration process which in turn reduces the amount of electrical energy required to run the compressor.
* The Air Conditioning System operates under the same principles as a Conventional Air Conditioning
System where refrigeration takes place as a result of the phase transition of the refrigerant.
* The difference between theAir Conditioning System and a Conventional System is how the vapour is
changed back into a liquid state in the refrigeration cycle.
* Conventional System uses a compressor to increase the pressure of the refrigerant when it’s in a vapour
state so that when it enters the condenser coil the combination of pressure and cooling from ambient air
condenses it into a liquid in the coil. The change of state of refrigerant begins to take place approximately
two thirds of the way down the condenser. The Air Conditioning System improves on this basic method
by using solar thermal energy collected in a solar collector to add thermal energy to the refrigerant vapour.
By using this method it reduces the amount of compression required to achieve the refrigeration cycle,
as well as utilising more of the cooling face of the condenser coil.
* By reducing the amount of compression required to achieve the refrigeration process the Air Conditioning
System can use less power in comparison to a conventional system. Similarly if enough solar thermal
energy is being collected and utilised the compressor will runs less often in the Air Conditioning System than
a Conventional System.
* The Air Conditioning System incorporates off centre fan blade technology, insulated foam ducts and
high performance brand name compressors to achieve optimum performance at a minimum level of noise.
The Air Conditioning System typically creates 10dBA less noise than a Conventional System.

3.4 Trouble Shooting
NOTICE
If the actual pressure is higher than shown, the system is most likely over-charged, and charge should
be removed. If the actual pressure is lower than shown, the system is most likely undercharged, and
charge should be added.
PUMP DOWN
This is performed when the unit is relocated or the refrigerant circuit is serviced.
Pump Down means collecting all refrigerant into the outdoor unit without the loss of refrigerant.
CAUTION
Be sure to perform Pump Down procedure in the cooling mode.
Pump Down Procedure
1. Connect a low-pressure gauge manifold hose to the charge port on the gas side service valve
2. Open the gas side service valve halfway and purge the air in the manifold hose using the refrigerant
3. Close the liquid side service valve(all the way)
4. Turn on the unit's operating switch and start the cooling operation.
5. When the low-pressure gauge reading becomes 1 to 0.5kg/cm2 G (14.2 to 7.1 P.S.I.G.), fully close the
gas side valve and then quickly turn off the unit. Now Pump Down procedure is completed, and all
refrigerant is collected into the outdoor unit.

Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle)
WARNING!
In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the Power
Supply Plug or turn off the circuit breaker, and consult authorized service personnel. Merely turning off
the unit’s power switch will not completely disconnect the unit from the power source. Always be sure
to turn off your circuit breaker to ensure that power is completely off.
Before requesting service, perform the following checks
Symptom Problem
NORMAL Doesn’t operate
FUNCTION immediately: If the unit is stopped and then immediately started again, the compressor
will not operate for about 3 minutes, in order to prevent fuse blowouts.
Whenever the power supply plug is disconnected and then
reconnected to a power outlet, the protection circuit will operate for
about 3 minutes, preventing unit operation during that period.
Noise is heard: During operation and immediately after stopping the unit, the sound of
water flowing in the air conditioner’s piping may be heard.Also, noise
may be particularly noticeable for about 2 to 3 minutes after starting
operation (sound of coolant flowing).
During operation, a slight squeaking sound may be heard. This is the
result of minute expansion and contraction of the front cover due to
temperature changes.
* During Heating operation, a sizzling sound may be heard occasionally.
This sound is produced by the Automatic Defrosting operation.
Smells: Some smell may be emitted from the indoor unit. This smell is the result
of room smells (furniture, tobacco, etc) which have taken into the air
conditioner.
Mist or steam
are emitted: During Cooling or Dry operation, a thin mist may be seen emitted from the indoor unit. This results from the sudden Cooling of room air by the air
emitted from the air conditioner, resulting in condensation and misting.
* During Heating operation, the outdoor units fan may stop, and steam may
be seen rising from the unit. This is due toAutomatic Defrosting operation.
Airflow is weak
or stops: * When Heating operation is started, fan speed is temporarily very low, to
allow internal parts to warm up..
* During Heating operation, if the room temperature rises above the
thermostat setting, the outdoor unit will stop, and the indoor unit will
operate at very low fan speed. If you wish to warm the room further, set
the thermostat to a higher setting.
* During Heating operation, the unit will temporarily stop operating
(between 7 and 15 minutes) as the Automatic Defrosting mode operates.
The fan may operate at very low speed during Dry operation or when the
unit is monitoring the room’s temperature.
In the monitor AUTO operation, the fan will operate at very low speed..

Operating Tips
Auto Restart
In event of power interruption
If the air conditioner power has been interrupted by a power failure The air conditioner will then restart
automatically in its previous mode when the power is restored.
If a power failure occurs during TIMER operation, the timer will be reset and the unit will begin (or
stop) operation at the new time setting.
Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter
may cause the air conditioner to malfunction. In this event, temporarily disconnect the Power Supply
Plug, reconnect it, and then use the remote control unit to resume operation.
