the beginning of summer and winter. (Dirt and dust
caught in the air filter causes a drop in airflow, which
leads to a decline in performance.)

When using the unit in a location where dirt may easily
accumulate, clean the filter(s) more frequently. Once
every 2 weeks is recommended.

may be cleaned by spraying the fins with low pressure
water in a downwards direction (ie. simulating heavy
