3. Installation Guide

3.1 Preparation Steps

1. Measure and mark pipe lengths accurately

2. Use dedicated PPR pipe cutter for clean, square cuts

3. Remove all burrs and clean connection surfaces

4. Mark insertion depth on pipe (typically 1.1-1.5 times pipe diameter)

3.2 Heat Fusion Process

1. Set welding machine to 260°C (±5°C)

2. Simultaneously heat pipe end and elbow socket

3. Recommended heating times:

   • DN20-32: 5-8 seconds

   • DN40-63: 8-12 seconds

   • DN75-110: 12-20 seconds

4. Join components quickly and maintain firm pressure

5. Allow cooling time (minimum 2-5 minutes depending on size)
