DIYvan's patent pending Dometic RTX 2000 AC Adapter ensures a secure and level installation of your air conditioner by matching the contour of the OEM roof. This prevents distortion of the sheet metal and aids in precise AC placement. CNC-machined from UV- and fire-resistant expanded PVC, this durable adapter is also compatible with the Dometic RTX 1000. Each of the options are sold separately.
The measurement for the outside adapter is determined by taking a measurement from the center of the large plug on the rear of the van to the back edge of the hole you will cut. See picture below.
Installation Guide for Dometic RTX 2000 Air Conditioner Adapter
Recommended Adhesives:
Sikaflex 221 – Ideal for bonding between the van roof & adapter and the adapter & spacer.
3M 90 Spray Adhesive – Best for securing the spacer to the foam seal.
A Bead of Silicone – Applied between the AC unit and the foam seal.
Dicor or similar adhesive – Around edges and on to the roof a couple inches.
Installation Steps:
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. Dicor self leveling sealant also works but looks a little messy.
** It is a good idea to check the integrity and reapply the sealant every so often.
Spacer Thickness Adjustments
Due to the manufacturing process, spacer dimensions may slightly vary:
1" spacer → ~7/8"
0.75" spacer → ~5/8"
0.5" spacer → ~7/16"
