MVZ-A·AA4(7), SVZ-KP-NA and PVA-A·AA4(7) models:
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 MVZ-A·AA4(7), SVZ-KP-NA and PVA-A·AA4(7) 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 Mode/
Function 08/108 is set to “3”.
The table below explains the proper settings for Mode/Function 08/108 and 10/110 for Vertical, Horizontal Left and
Horizontal Right installations.
0.6 in. WG (150 Pa)
Notes:
For Installation above 0.50 in. WG
External Static Pressure
MVZ-A·AA4(7) and PVA-A·AA4(7) models:
For downflow installations, the following table explains the proper settings for Mode/Function 08/108 and 10/110. Again,
the external static pressure in the downflow configuration cannot exceed 0.60 in WG.
0.6 in. WG (150 Pa)
Notes:
For Installation above 0.50 in. WG
