Installation & Product Tips
- Ceiling Access Required: Each OuttaSight unit requires above-ceiling access for mounting, line set routing, and condensate drain connection. Plan your installation carefully before ordering.
- Condensate Drain: Each cassette unit requires a condensate drain line. Route to a floor drain or use a condensate pump if gravity drainage is not available.
- Ceiling Grid Compatibility: The OuttaSight mounts in a standard 2×2 ft suspended ceiling grid. For drywall ceilings, a custom framed opening is required.
- Line Set Length: Each zone requires its own line set. Maximum line set length is 75 ft per zone. Order the correct length for each zone separately.
- Register Your Warranty: Register all components at mrcool.com within 30 days of installation to activate the 7-year compressor and 5-year parts warranty.
