M-Series Water Purification Machines
1238160 Rev. D 2 - 3 Installation Guidelines and Instructions
2.1 Mounting
M-Series machines are equipped with a frame that supports the machine. Allow
at least 45 inches (114 cm) of space at the top of the sepralator housing(s) for
removal and loading of sepralators. If 45 inches (114 cm) are not available, the
entire membrane element housing may have to be removed for element
changes. At least 6 inches (15.2 cm) are required at the end of each sepralator
housing if the entire sepralator housing will be removed to replace sepralators.
2.2 Plumbing
2.2.1 Inlet Plumbing
The feedwater source is plumbed to the inlet using ¾-inch NPT fittings. A 1-inch
FNPT cleaning port is installed in the inlet plumbing. A pressure regulator is
installed between the permeate outlet and the membrane elements, so that if the
pressure exceeds 60 psig the regulator will allieviate the excess pressure.
2.2.2 Valves Required for (CIP) (Not Factory Installed)
A pipe tee is installed in the inlet line. Install a valve on the inlet and on the
cleaning port to facilitate cleaning the RO. Install a tee with 2 two-way valves or
a single three-way valve on the permeate and concentrate outlets to allow flow
back to the cleaning tank. Never operate the machine with the concentrate or
permeate lines blocked. Severe damage to the unit may result. (Refer to Figure
3 for representative system flow schmatic.)
2.2.3 Concentrate Outlet Connection
Install the CIP valve on the concentrate outlet and connect a ¾-inch hose or pipe
and run it to an open drain. The concentrate outlet plumbing should be placed at
a height at least equal to the height of the machine to avoid drainage from the
machine during non-operation. A siphon break may also be installed in the
concentrate line for added protection. The concentrate outlet hose can be any
length, and the diameter should match the outlet on the machine. [Maximum
back pressure is 60 psig (4.1bar).]
2.2.4 Permeate Outlet Connection
Install the CIP valve on the permeate outlet. The pure water (permeate) should
be transported to the point-of-use via non-corroding type tubing, pipe, or hose.
Examples are: food-grade flexible nylon tubing, stainless steel tubing, or PVC
hose. The permeate outlet is ¾-inch FNPT for all M-series RO’s.
