If you are replacing an existing AZ75 or AZ85 VTAC and installing the new AZ90 or AZ91, the RAVTRANS Kit is required. It is a transition piece that adapts the new vertical air conditioner systems to fit the older wall plenums. It will add about 2.5" to the depth (front to back). It is to be used with:
- RAVWP6 - for installations with walls up to 6" thick
- RAVWP8 - for installations with walls up to 8" thick
- RAVWP12 - for installations with walls up to 12" thick
- RAVWP15 - for installations with walls up to 15" thick
The kit includes the transition plenum, 4 pieces of insulation (top, bottom and 2 side pieces), drain pan and 6 screws.
NOTE: Although the installation instructions state that this transition will not work with the Large Chassis 18000 BTU heat pump models, a few minor field adjustments to the RAVDP18 Drain Pan (cutting off a corner and adding bit of silicon) will allow it to be used.
