Typical Downflow Installation
Important: Ensure EEV sensor and motor wiring
are taut and wire-tied to the distributor tube to pre-
vent damage during electric heat operation.
Important: For the 5 ton air handler model, tap 5
should not be used in the downflow or horizontal
orientations. Using Tap 5 could result in water
blowing off the coil.
