• Rheem
®
Indoor Coils are designed for use with Rheem outdoor units and are available for vertical upflow or downflow,
and horizontal left or horizontal right airflow. When matched
with Rheem outdoor units, the coils provide a nominal capacity range from 18,000 BTU/HR [5.24 kW] to 48,000 BTU/HR
[14.06 kW].
• Constructed of aluminum fins bonded to internally grooved
copper tubing.
• Tin plated copper tubing in the finned area for superior corro-
sion resistance in harsh environments.
• Coils are tested at the factory with an extensive refrigerant
leak check.
• Coils have sweat refrigerant connections.
• Ideally suited for new installations or add on air conditioning.
• Feature two sets of
3
/4" [14.1 mm] N.P.T. Condensate drain
connections for ease of connection.
• Coils are AHRI certified for system application with variety of
Rheem outdoor units.
• Condensate drain pan is constructed of high grade, heat
resistant, corrosion free thermal-set material.
• Compatible with Germicidal Light System (UV resistant)
• Bi-Directional airflow eliminates the need to switch any inter-
nal components from horizontal left to right.
• Unique drain pan design maximizes application flexibility and
condensate removal.
• Universal Duct Flanges are included with all coil models.
