Installation & Product Tips

• Verify compatibility with your specific MRCOOL DIY model before ordering — not all DIY models use No-Vac line sets
• Do not cut, modify, or extend the precharged line set — order the correct length for your installation
• Route carefully to avoid kinks — use a tube bender for turns greater than 45 degrees
• Coil any excess line set near the outdoor unit without restricting airflow
• The quick-connect fittings are self-sealing — no brazing or vacuum pump required
