UCTWORK
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.

ONNECTION
An external condensate drain trap is required with this unit. See
your distributor for details. For proper unit operation, the trap must
be filled either before a cooling startup or during a unit “cycle-off”
after 20 minutes of running on first cycle. This drain can be ex-
tended using 3/4” PVC piping.
*NOTE: Please contact your distributor or our website for the applicable product data book referred to in this manual.
