How to Install a VRF System — Step-by-Step Guide
Installing a VRF (Variable Refrigerant Flow) system requires expert planning and precision. At SNOVAC, we ensure every project follows strict design and safety standards to deliver long-lasting performance.
→ 1. Planning: Review HVAC layout, select ideal indoor and outdoor unit locations, and confirm power, drain, and pipe routes.
→ 2. Outdoor Unit Installation: Mount on a solid base with anti-vibration pads and ensure proper airflow clearance.
→ 3. Indoor Unit Installation: Fix cassette or ducted units as per design, maintain correct slope for drain, and ensure insulation.
→ 4. Refrigerant Piping: Use seamless copper pipes, braze under nitrogen, test with dry nitrogen (550 psi), and vacuum below 500 microns before charging refrigerant.
→ 5. Electrical Work: Provide dedicated supply, correct cable size, and communication wiring.
→ 6. Drain Line: Maintain slope and test for leakage.
→ 7. Testing & Commissioning: Verify cooling, pressure, and temperature; record performance readings.
Proper VRF installation ensures higher efficiency, lower running cost, and longer system life.
