The external static pressure cannot exceed 0.60 in. WG for any position installation when an electric heat kit is installed on
the Multi-Position air handler
.
The static pressure setting for any PVFY-A·NAMU models are set to 0.50 in. WG from the factory. If an electric heat kit is
installed and the static pressure exceeds 0.50 in. WG, it is extremely important that SWA is set to the “3” position.
0.6 in. WG
(150 Pa)
Notes:
For Installation above 0.50 in. WG External Static Pressure
Switch A will be in the “3” position
