Installation Instructions
- Preparation and Mounting: Aluminium pipes require specific installation techniques to accommodate expansion. Avoid constraining pipes at both ends to prevent stress and buckling. Start by attaching horizontal pipe clips, then vertical ones after slight pressure application.
- Spacing Requirements: Maintain about 10cm distance from walls and columns, and at least 400mm between pipe fittings and clips.
- Expansion Management: Utilize expansion bends for long runs to handle thermal expansion.
- Air Quality Control: Use filters and John Guest Water Trap Tees to ensure clean, dry air in the system, improving equipment life and performance.
- Pipe Sizing: Choose pipe size based on the flow rate and pressure drop requirements. Consult the flow rates for both nylon and aluminium pipes to make an informed decision.
