J4AH4E Installation Manual

NOTES: Airflow based upon cooling performance at 230V with no electric heat and no filter.Airflow at 208V is approximately the same as 230V
because the mult-tap ECM motor is a constant torque motor. The torque doesn’t drop off at the speeds in which the motor operates.
The air distribution system has the greatest effect on airflow. The duct system is totally controlled by the contractor. For this reason, the contractor
should use only industry-recognized procedures.
Heat pump systems require a specified airflow for electric heat operating. Each ton of cooling requires between 350 and 450 cubic feet of air per
minute (CFM), or 400 CFM nominally.
Duct design and construction should be carefully done. System performance can be lowered dramatically through bad planning or workmanship.
Air supply diffusers must be selected and located carefully. They must be sized and positioned to deliver treated air along the perimeter of the
space. If they are too small for their intended airflow, they become noisy. If they are not located properly, they cause drafts. Return air grilles must
be properly sized to carry air back to the blower. If they are too small, they also cause noise.
The installers should balance the air distribution system to ensure proper quiet airflow to all rooms in the home. This ensures a comfortable living
space.
An air velocity meter or airflow hood can be used to balance and verify branch and system airflow (CFM).
--- Shaded boxes represent airflow outside the required 300-450 cfm/ton.
