Safety Information
Safety Warnings:
The Koolsola Solar Air Conditioning system should only be installed repaired and maintained by
a qualified, licensed air conditioning installer.
Please switch off the power to the system in the event of an electrical storm in order to prevent
damage to the system.
Please switch off the power to the system when it is not in use for long periods of time.
Please switch off the power to the system before conducting any cleaning of or maintenance of
the system.
Never clean the system with liquid detergents liquefied cleaning agents or corrosive cleaning
agents. Never allow the indoor unit to come into contact with liquid. Any of these actions may
cause damage to the plastic accessories and casings or cause damage to the electrical
components.
Never insert your hands or any other object into the air outlet of the indoor and outdoor units
to ensure that there is no damage to the high-speed fan or the object being inserted.
Never allow children to play the system.
Never remove any of the coverings of the system.
Never allow moisture to get into the remote control.
Never put or use any combustible liquid or substance such as hair spray, paint or petrol near the
machine to prevent the possibility of fire.
If any unusual circumstances occur, including but not limited to; strange noises or smells,
smoke, abnormal temperature increases or changes to appearance of components please
switch off the power immediately and contact your local distributor of the Koolsola Solar Air
Conditioning System. Do not attempt to repair the system yourself.
Pre-checking before operation:
Please refer to the Section 2.3 – Routine Maintenance to establish the correct method for
cleaning the air filter and checking/filling the solar collector with water.
If the system has been switched off/idle for a long period of time please clean the air filter
before turning the system back on.
If the system has been switched off/idle for a long period of time please check the level of the
water in the solar collector and add water if required.
In normal operating conditions please clean the air filter every 2 weeks.
In normal operating conditions please check the level of the water in the solar collector every 3
months and add water if required.

1.2 System Operating Principles
The Koolsola Solar Air Conditioning System uses both mains electrical power and solar thermal
energy. The Koolsola Solar Air Conditioning System always requires mains electrical power to
operate fans and electrical control components.
The Koolsola Solar 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 Koolsola Solar 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 a Koolsola Solar Air Conditioning System and a Conventional System is
how the vapour is changed back into a liquid state in the refrigeration cycle.
A 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 Koolsola
Solar 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
Koolsola Solar Air Conditioning System can use an undersized compressor in comparison to a
Conventional System. Similarly if enough solar thermal energy is being collected and utilised the
compressor will run less often in a Koolsola Solar Air Conditioning System than a Conventional
System.
The Koolsola Solar 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 Koolsola Solar Air Conditioning System typically
creates 10dBA less noise than a Conventional System.
