Dometic RTX 2000 Patent Pending adapter matches the contour of the Nissan full size OEM roof so the air conditioner mounts to a flat surface. Prevents distorting the roof sheet metal and can be used as an aid for locating the AC. They are CNC machined out of UV and fire resistant expanded PVC. This same adapter will work with the RTX 1000 unit. Each of the options are sold separately.
AC Adapter Install procedure: We recommend 3m Window-weld adhesive which you can get at Napa. Locate and cut the hole. You can use the adapter as a guide to mark the hole. Stay clear of roof supports, obviously. Make a tape line 1/4" beyond the adapter perimeter. De-gloss the area with a Scotch- brite pad. No need to scuff. Just dull the paint. Clean with isopropyl alcohol and let dry thoroughly. Blow dryer if it's wet and/or cold out. Apply a good amount of the Window-weld on the face of the adapter. Then press the adapter down onto the roof until the adhesive oozes out the sides. It's not necessary to clamp. If you do, use a lot of lightly set clamps and spread out the clamp force over the whole surface area. Using the adhesive that oozes out, make a fillet around the adapter with a double gloved finger. Pull the tape within 15 minutes. Cure is fast on outside. Let cure overnight and then proceed with the AC install per the AC instruction. Seal the adapter and onto the roof about 1/2" with brush on bed-liner or Flexseal from the TV guy works well. Good idea to check the integrity and reapply the sealant every so often. Dicor self leveling sealant also works but looks a little messy.
Due to our process the 1" spacer is closer to 7/8", the .75" spacer is closer to 5/8" and the 1/2" spacer is closer to 7/16" .
If ordered, the support strips are for the interior of the van. They are glued in with the 3M Window Weld.
Watch Hein's youtube video about this product and the choices.
Many customers ask what to glue the adapter and spacers and seal down with. We recommend:
Sikaflex 221 between the van roof and the adapter,
Sikaflex 221 between the adapter and the spacer,
3M 90 spray between the spacer and the foam seal,
Bead of silicone between the Unit and the foam seal,
Dicor or the like around edges and on to the roof a couple inches.
