8. Installation

PAA unit shipment contains the following items:
1. Cased coil (includes pre-installed, TH2 / TH5 pipe thermistor assembly)
2. Control box
3. Accessories bag
4. L-bracket
PAA units are shipped factory installed with internal vertical and horizontal drain pans, which can be
configured for vertical / downflow, horizontal right or horizontal left configurations. Internal horizontal drain
pan is not required for vertical configurations.
In vertical / downflow configurations, aluminum foil tape must be applied to seal the top edge of the
insulation to the cabinet. This tape will prevent the possibility of the insulation delaminating and blocking
airflow. Coil should be level or pitched slightly toward the drain connection.
