Daily Maintenance Guide for PPR Fusion Machines

I. Post-Use Daily Procedures

  1. Cleaning Heating Molds
    • Wait until temperature drops below 80°C, wipe off plastic residues with pure cotton cloth
      (Strictly prohibit metal brushes or chemical solvents)
    • Remove stubborn carbon deposits with wooden scrapers gently to avoid damaging PTFE coating
  2. Inspecting Power Cords & Plugs
    • Check for exposed copper wires, scorch marks, or deformation
    • Immediately stop use and replace with genuine parts if abnormalities are found

II. Periodic Component Maintenance

ComponentMaintenance IntervalKey Procedures
Heating MoldsEvery 3 monthsCheck coating integrity after disassembly; replace if peeling area >5mm²
Temp SensorsEvery 6 monthsClean probes with anhydrous alcohol; recalibrate (return if error >±3°C)
Fan FiltersMonthlyRemove dust with vacuum; wash with water and dry thoroughly (clogging causes overheating)

III. Long-Term Storage Protocol

  1. Apply high-temperature anti-rust grease on mold surfaces, wrap with grease-proof paper
  2. Store in environment with humidity <60%, avoid temperatures below -15°C

*Notes:

  • PTFE = Polytetrafluoroethylene
  • All measurements strictly follow original specifications*
