3030226 Rev. D 1-9 General Information
1.6.4 Water Purity
Plumbing materials can significantly contribute to the contamination of the water.
Metallic pipes (with the exception of 316 stainless steel) must be eliminated once the
purification process has begun. Schedule 40 or 80 PVC pipes, polypropylene, PVDF, and
other FDA recommended materials are suitable for most grades of purified water. Care
must also be exercised in the choice of a thread sealant.
1.6.5 Temperature
The RO is normally connected to a cold water supply. The performance specifications of
the RO are based on 77°F (25°C) RO feed water temperature. The Millenium HX
contains a VFD motor that will increase the pump speed when operating on cold water
helping to increasing the amount of product water produced.
