When replacing the fan, please wear gloves and other protective equipment.
→Contact with parts inside the product such as evaporator (aluminum fan) may cause injury.
Use the specified filter for replacement. Use of fine filters will cause efficiency loss in heat releasing which leads
to reduced cooling performance and/or breakdown of the unit.
Cleaning and user maintenance shall not be made by children.
The appliance shall not be cleaned with a water jet.
The cooling circuit of Compressor Cooler has been filled with a required
amount of refrigerant, tested for leaks and subject to a trial run before
delivery.
Therefore, there is no need of maintenance for the circuit.
The durability of Compressor Cooler is generally 30,000 operating hours,
provided that its filter is kept clean. Depending on the environmental
condition at the site of use, check and clean the filter, if used, at least once a
week.
Clogging on filter may lead to deterioration in cooling performance, or at
worst, may cause shutdown of the unit due to overloading on the compressor.
