Installation & Product Tips

  • Drill the wall hole at a slight downward angle toward the outside to promote drainage
  • The sleeve should fit snugly in the hole — use foam sealant around the sleeve for an airtight seal
  • Install the decorative cap on the exterior side for a finished, professional appearance
  • Seal the interior side with foam sealant or caulk to prevent air infiltration and pest entry
  • Use a 3-inch hole saw for standard MRCOOL DIY line set bundles
