- Horizontal-right configuration requires relocation of the drain pan.
- Allow at least 24 inches in front of the air handler for service access.
- When installed above a finished ceiling, place an emergency drain pan directly below the unit as required by local and state codes.
- Elevate the air handler on sturdy, non-porous material where it may become wet.
- Use a protective barrier where the air handler may be exposed to physical damage.
- Designed for a complete supply-and-return ductwork system.
Important: This is an individual indoor air-handler listing. A compatible outdoor condenser, refrigerant piping, electrical work and commissioning are required for a complete system.
