DUCTWORK
Duct systems and register sizes must be properly designed for the C.F.M. and external static pressure rating of the unit. Ductwork should be designed in accordance with the recommended methods of Air Conditioning Contractors of America Manual D (Residential) or Manual Q (Commercial). All ductwork exposed to the outdoors must include a weatherproof barrier and adequate insulation.
A duct system should be installed in accordance with Standards of the National Board of Fire Underwriters for the Installation of Air Con- ditioning, Warm Air Heating and Ventilating Systems. Pamphlets No. 90A and 90B.
The warm air supply duct from the unit through a wall fabricated of combustible material may be installed without clearance. However, minimum clearances for the unit must be observed (see appendix in back of manual).
The outlet duct should be provided with an access panel.
For vertical airflow, the ductwork should be attached to the roof curb prior to installing the unit. Ductwork dimensions are shown in the Amana ® PRC roof curb installation manual.
If desired, supply and return duct connections to the unit may be made with flexible connections to reduce possible unit operating sound transmission.

1Based on a face velocity of 300 f t./min. 2Based on a f ace velocity of 600 ft./min.
If using the Over/Under Transition Kit, the filter(s) may be located in the return air duct(s) or return air filter grille(s). Filters installed exter- nal to the unit should be sized in accordance with their manufacturer recommendations. A throwaway filter must be sized for a maximum face velocity of 300 feet per minute.
