psig (4.1bar) or fluctuates by more than 5 psig (0.4 bar), a pressure regulator should
be installed ahead of the CIP tee.

Valves Required for CIP, ECN Models Only

IMPORTANT NOTE: GE has installed a plugged pipe tee in the inlet line of the E4H
units. This plug, when removed, will facilitate cleaning of the unit. A tee with (two)
two-way valves or a single three-way valve should also be installed 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.
2.2.3.

Concentrate Outlet Connection

Install the CIP valve on the concentrate outlet tee, connect a 1-inch hose or pipe, and
run it to an open drain. To avoid drainage from the machine while not in use, the
concentrate outlet piping should be placed at a height at least equal to the height of
the machine. 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 backpressure is 60 psig (4.1 bar).]
2.2.4.

Permeate Outlet Connection

Install the CIP valve on the permeate outlet tee. 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 1-inch FNPT.

2.3. Electrical

The DLX and ECN E-Series models are supplied with a single-phase, 110 VAC 60 Hz or
220 VAC 50 Hz control circuit and 8-foot cord which plugs into a three-prong
grounded receptacle. For 220 VAC, 50 Hz units, plug must be customer-supplied. A 20
amp dedicated service circuit is required for proper operation.
For each model, the motor is wired at the factory to an overload protection magnetic
motor starter, which is controlled by a panel-mounted manual switch.
The electrical system control circuit is separate from the motor voltage. Therefore,
two supply voltages are required for electrical wiring in the field, the control circuit
voltage and a separate three-phase motor voltage. All field wiring must comply with
applicable local and national electric codes.
2.3.1.

ECN Electrical System

• Connect the control circuit power cord to 115 VAC, 60 Hz, or 220 VAC, 50 Hz, single-
phase power.
• Connect the magnetic motor starter 230/460 VAC or 220/380 VAC, three-phase
power to match the motor voltage and phase. Check the tag (located on the motor
