Check the following at least once a year:
▪ Heat exchanger
▪ Water filter
Heat exchanger
The heat exchanger of the outdoor unit can get blocked up due to dust, dirt,
leaves, etc. It is recommended to clean the heat exchanger yearly. A blocked heat
exchanger can lead to too low pressure or too high pressure leading to worse
performance.
Water filter
Close the valve. Clean and rinse the water filter.
NOTICE
Handle the filter with care. To prevent damage to the mesh of the filter, do NOT use
excessive force when you reinsert it.
