💡 What steps stop condensation when mounting a wall bracket for indoor minisplit tubes?
I recommend clearing debris from the old masonry cutout first so the gasket sits flush against stable framing. Here is how to secure it properly:
- Cut a precise circle matching the appliance tubing diameter to prevent cold air leakage through unsealed gaps.
- Press the rubber washer firmly into place before snapping the outer shell together so moisture stays locked out of sheetrock.
- Apply expanding spray foam behind the frame for a handy upgrade that adds a solid rodent barrier.
