Plumbing
Refer to the P&ID on page 31 for further information.
Note:
All plumbing is to be done in accordance with state and local codes.
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 min pressure 40 P.S.I. Max pressure 100 P.S.I. A
pressure regulator may be required.
View of the side of the system. Please note these points
may vary from system to system.
Concentrate/Reject Connection
Connect a line to the concentrate connection point on the skid (refer to
picture). The drain must have a minimum capacity which meets or
exceeds the concentrate output of your system. Check the Design
Specification (pages 3-4) for your model.
Permeate/Product Water Connection
Connect the product water line to the product connection point on the
system (refer to picture). Run this line to your storage tank or other
downstream equipment, observing the following:
Run this line in such a manner as to minimize static head
pressure in the product line.
A check valve is recommended to prevent back flow to the RO
membranes. This check valve should be installed on the output
of the product connection point.
View of the back of the control panel. Please note these
points may vary from system to system.
The product line should have no restrictions to the product flow.
Connect the product line to a bulkhead fitting at the top of the storage tank.
Caution:
RO Membranes will fail immediately if the product water is allowed to flow backward into the
elements. Use a check valve and ensure that there are no restrictions on the product flow to prevent
backflow.
Caution:
The highest point of the tubing should not be higher than four feet above the top of the RO
modules, or the elements may be damaged.
