Maintenance
(1).It is to be noted to change the water while the cooler is in work to avoid incrustation.
(2).The filter pads should be cleaned more often to keep the cooling efficient. Do not use water above 40℃. Banister brush can be used softly to scrub away the dust on the pads.
(3)The water supply should be shut off to avoid bacteria as well as cold weather. It is also recommended covering to protect the cooler in some dusty and snowy cities.
(4).We recommend to clean the pad every month to keep the cooler under best condition.
