💡 Pro Tip: Managing Line Length

If your 25ft lineset is longer than your route, do not shorten or cut the lines. Simply coil the excess into a large horizontal loop and store it flat behind the outdoor unit. This ensures optimal R-454B refrigerant flow and prevents oil traps that can damage the compressor.

📋 Setup & Verification Checklist

Check Compatibility: Confirm both the air handler and condenser are 5th Gen R-454B.

Tighten Properly: Hand-tighten Quick Connect fittings first, then torque until secure.

Leak Test: Use soapy water on connections after opening valves to verify a total seal.

Pro Cable Wiring: Carefully match wires 1, 2, 3, and Ground to their specific terminals.
