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
