  • Temperature and pressure relationship is for operational purposes andnot failure pressure.
  • Don't use MANIFLOW in continuously circulating hot water loops of above 60°C without expert consultation.
  • Always install MANIFLOW to AS/NZS3500 National Plumbing Code standards.
  • Keep it shielded or painted to protect it from UV light if you're fitting orstoring it externally for extended periods.
  • Avoid exposing MANIFLOW to petroleum solvents.
  • Insulate MANIFLOW in areas where freezing is possible.
