The Performance Characteristics of Solar Air Conditioners
The Koolsola product uses solar thermal energy to improve the operation of the condenser thus
reducing the amount of electrical energy required for operation
Once stability is reached, the compressor is only required infrequently. Service life is therefore
extended.
The condenser is 10dBA quieter than conventional. The fan head uses an advanced off-center blade
fan and foam air duct. This results in higher performance and lower noise.
The reverse cycle function enables economical heating on cold days
The design is elegant and graceful while practical.
It uses microprocessor control. The operation is convenient and simple. The solar air conditioner is also
provided with an automatic detection display system. You will feel comfortable and socially responsible with
our solar air conditioner.

Common Faults Diagnosis and Elimination
Non-failure Conditions
1. When you turn on or turn off the solar air conditioner, sometimes you will hear sizzle sound,
which is the flowing sound of the cooling agent, and is not a malfunction.
2. The solar air conditioner cannot restart at once after it stops, even though it is switched on.
Within 3 minutes, the compressor will not run in cooling, dehumidifying or heating modes.
3. Sometimes, the solar air conditioner absorbs stale air. This collects in the filters. Under such
conditions, there is no problem with the solar air conditioner. The filter screen needs cleaning.
4. When heating, the indoor machine and the outdoor machine may stop simultaneously, but the
compressor still runs. It is on defrosting mode. The heating performance will continue after
defrosting has finished.
5. When heating, the outdoor machine may generate condensation. This is a result of defrosting
and thawing, and is not a malfunction.
How to Save Energy:
Never block the air inlet and the air outlet of the solar air conditioner. The air conditioner will not
run normally and may be damaged if the outlets are obstructed. When cooling, please avoid
direct sun radiation into the room. Please pull curtains or shutters. If the walls and ceiling of the
room are not insulated the cost of cooling will be greater. Please keep the air filter clean.
Blocking of the filter screen will greatly reduce the efficiency of the air conditioner. Keep the
window, door and any openings closed, so as to avoid cooling air escaping.
