2.0INSTALLATION

The following installation guidelines will help you install your new E-CE RO machine.

2.1Feed Water Requirements

The following feed water requirements must be met before installing your new E-CE RO machine to ensure quality permeate and extended membrane element life.

Table 2.4

Feed Water Requirements

Temperature Typical: 10 - 29°C (50° - 85°F)

Inlet Pressure	Minimum: 2.1 barg (30 psig)
	Maximum: 4.1 barg (60 psig)
Chlorine (continuous feed)	0 ppm
Feed Water	For soft water [less than 1 grain per gallon
	(gpg) or 17 mg/L hardness]
	acceptable pH: 3.0 - 11.0
	For unsoftened water (contact factory for
	water analysis), acceptable pH: 5.0 - 6.0
	For short-term (i.e., cleaning) acceptable
	SDI range: 2 - 12

Silt Density Index	Less than or equal to 4 to minimize mem-
(SDI)	brane element fouling and extend cleaning
	intervals. Refer to ASTM Standard
	D4189

2.2Mounting

E-CE Series machines are equipped with a stand-alone frame, which supports the machine. At least 114 cm (45-inches) of space should be allowed on each end of the
