2 Weekly Air Filter Maintenance

Be sure to wash the air filter with water at 40˚C or lower temperature every two weeks.

If the air filter is clogged with dust, the wind volume reduces, resulting in capacity deterioration. Also, the compressor’s protection device is activated, hindering smooth operation. Furthermore, it causes power consumption increase.

Operating the unit without the air filter causes a fault.

To remove the air filter, hold the bottom of the filter with both hands, and push it up while warping it forward.

NOTE! If the air filter is clogged, the cooling capacity deteriorates, resulting in excess power consumption. Clean the air filter periodically to save power consumption.
