The RAVTRANS4 transition kit is required when replacing your older AZ90 and AZ91 Series VTACs with the newer AZ95 units. The RAVTRANS4 kit is to be used when replacing AZ90 and AZ91 series units with an existing RAVWPT14 wall plenum.
Differences in chassis designs between the AZ90/AZ91 series and AZ95 series require careful installation and planning. Changes in drain exit locations and drain routing, electrical connections, platform height, and conditioned air duct locations are all items that need to be considered when replacing an AZ90/ AZ91 series unit with an AZ95 series unit.
The kit includes the transition plenum with air divider, front bracket and screws. It is 33-7/10"h x 23-7/10"w x 12-1/8"d.
If you are replacing an AZ75 or AZ85 with an AZ90/91 you will need a RAVTRANS. If you are replacing it with an AZ95 you will need a RAVTRANS2. If you are replacing an AZ90/91 with an AZ95 you will need a RAVTRANS3 or RAVTRANS4.
