The regulator controls the outlet pressure from the nitrogen cylinder to the specified test pressure — typically 40–42 bar for R410A and R32 systems. Never use refrigerant gas for pressure testing.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat test pressure should I use for R32 systems?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eR32 systems are typically pressure tested to 40 bar (high side) in accordance with the system manufacturer's commissioning instructions and BS EN 378.
