 Replacing the compressor must be carried out by professional personnel, if necessary, please contact
Emerson technical support engineer.
 The damage to the compressor components due to improper way of cleaning is classified in the warranty
agreement as improper usage of the product, thus is not covered by the warranty.
When the compressor is entirely burned, you need to replace the filter drier together with the compressor. In addition,
check the expansion valve. If the valve is faulty, replace it too. Before the replacement, you must clean the system. If
you are unsure about the cleaning method, please consult with Emerson service personnel.
