Plumbing Installation must conform to Local and National Codes.
Any installation work must be carried out by suitably qualified personnel.
CAUTION: This unit produces high quality water which can cause corrosion or leaching of
the plumbing following the system.
Use only plumbing components of inert material that are compatible with the application.
Copper plumbing cannot be used.
Plumbing materials can significantly contribute to the contamination of the water. Care must be exercised over the choice
of thread sealants. Teflon tape is suitable for all threaded connections in this system. Pipe dope can leach objectionable
impurities into the water and must be avoided.
Feed Water Connection
Connect the raw water supply to the inlet of the solenoid valve (P.O.C), observing the following:
•
The line size shall be 3/4” or larger to minimize pressure loss.
•
A manual valve may be installed on this line to shut off the water supply if it will ever be needed. Be sure that this
valve in no way restricts the water flow when it is fully open.
•
Water supply minimum pressure 40 P.S.I., maximum pressure 100 P.S.I. A pressure regulator may be required.
