Installation Guidelines
Best practices for optimal performance and longevity
Do's
- ✓Select manifold outlets based precisely on the number of hot and cold water tops in each circuit.
- ✓Ensure all PEX installations follow the mobile installation method for maximum radiator efficiency.
- ✓Reference DIN 16893 working condition tables to determine permissible pressure for specific operating temperatures.
- ✓Use dedicated Red and Blue protective sleeves to clearly differentiate hot and cold water lines.
Don'ts
- ✗Do not exceed the maximum permissible working pressure for peak temperature service (e.g., 5.5 bar at 95°C for PN 12.5).
- ✗Avoid utilizing PEX piping that does not meet the general quality requirements of DIN 16892.
- ✗Do not ignore mandatory cooling times or rotate joints during associated fusion welding for fitting connections.
- ✗Don't overlook elongation calculations caused by temperature differences between installation and operation.
