Why R410A Requires Special Manifolds?

R410A operates at significantly higher pressures than older refrigerants like R22. Whilst this manifold set can be used with R410A, you'll need R410A-specific adapters (90413) to connect to R410A service ports, which use larger 5/16" fittings with 1/2"-20 UNF threads instead of standard 1/4" SAE fittings. The manifold itself is built to handle R410A's higher operating pressures safely.

R410A System Characteristics:

• Higher Operating Pressures – Up to 50% higher than R22
• 5/16" Service Ports – Requires adapters for connection
• 1/2"-20 UNF Thread – Different from standard SAE threads
• Colour Coding – Often pink/rose colour for identification
• POE Oil Required – Not compatible with mineral oil

Why Choose 90cm (36") Hoses?

• Standard Length – Ideal for most residential and light commercial applications
• Portable – Easy to transport and store
• Versatile – Suitable for most service situations
• Cost-Effective – Good balance of reach and affordability
• Easy to Manage – Not too long to be cumbersome

Free-Floating Piston Valve Advantage:

Unlike traditional twisting piston valves, Mastercool's free-floating piston valves move straight in and out, resulting in less wear and tear, longer service life, and more reliable sealing over time.

Benefits:

• R410A Ready – Designed for modern refrigerant systems
• Professional Quality – Forged brass construction ensures durability
• Large Gauges – 63mm dials are easy to read
• Multi-Refrigerant – Works with R410A, R507, R404A, R22
• Complete Kit – Everything needed to start servicing
• Free-Floating Valves – Longer service life, better sealing
• Professional Accuracy – 1.6 gauge class for precise readings
• Standard Hose Length – 90cm suits most applications

How to Use:

1. Connect R410A adapters (90413) to hose ends if servicing R410A systems
2. Connect blue hose to low-side (suction) service port
3. Connect red hose to high-side (discharge) service port
4. Connect yellow hose to refrigerant cylinder or vacuum pump
5. Open manifold valves as needed for charging or recovery
6. Monitor pressures on gauges during operation
7. Close valves when service is complete
8. Disconnect hoses and store manifold in case

Maintenance:

• Inspect hoses regularly for cracks or damage
• Check gauge accuracy annually
• Replace O-rings if leaks develop
• Keep valves clean and free from debris
• Store in protective case when not in use
• Avoid over-tightening connections

Replacement Parts:

• 85215 — O-Rings (4 pieces)
• 85216 — Seal and Seat Assembly (2 pieces)
