Comfort Plus
*
The return air plenum is factory supplied only with the 3100 series system. It can be ordered as an optional piece with
the 4100 series systems. The dimensions listed are those that the factory supplied return air plenum can accommodate.
For larger coils, the return air plenum must be installer supplied. If using an air conditioning or heat pump system with
the Comfort Plus, the Comfort Plus does not include the indoor coil or the outdoor compressor system as standard
equipment.
** The Comfort Plus system can accommodate most heat pump or air conditioner indoor coils provided the heat pump or air
conditioner is sized in accordance to supply air delivery rates of the Comfort Plus system. Equipment modifications are
required to fit larger coils.
