* Based on 27°C db/19°C wb indoor air temperature, 35°C outdoor air temperature and nominal air flow.
** Based on 20°C db indoor air temperature, 6°C outdoor air temperature and nominal air flow.
*** The required filter sizes shown are based on the larger of the rated cooling air flows or the heating air flow velocity of 1.5 m/s for throwaway type filters or 2.3 m/s for
high-capacity type filters. Air filter pressure drop for non-standard filters must not exceed 20 Pa.
