Machine Start-Up Preparation; Machine Start-Up - GE E4-2200 Operation And Maintenance Manual

The water analysis will provide information on what type of pretreatment may be
required and what recovery the machine can be run at on the feed water provided. If
the machine is moved to a different water source, a new water analysis should be
taken before operating the machine.
Your RO is designed to operate on tap feed water with an SDI of 5 or less. The pH
should be in a range of 5.5 - 8.5. Exposure to any levels of chlorine may cause
irreversible damage to the thin-layer composite (TLC) polyamide (PA) membrane
elements in your machine. Daily water checks are recommended to ensure the
integrity of your pretreatment and RO system.

3.2. Machine Start-Up Preparation

Check the function and integrity of your pretreatment equipment. Ensure that your
water softener and activated carbon filters have been leaked checked and properly
flushed, before starting up your RO machine.
CAUTION: Improperly flushed pretreatment may cause serious RO machine problems
at start-up.

3.3. Machine Start-Up

Turn the feed water supply ON, while checking for leaks in the pretreatment and inlet
feed water lines.
Check to ensure power to the motor is de-energized and the ON/OFF button on the
machine is in the OFF position.
Plug in the factory-supplied power for the control voltage.
For initial start-up, redirect the permeate and concentrate lines to the drain.
Open the concentrate and recycle flow control valves two complete turns. These
valves are positioned on the flow control plumbing in the top right rear section of the
machine.
Turn the ON/OFF button on the machine ON. System will open allowing water to flow
through the machine to the drain through the permeate and concentrate CIP valves.
Let the machine run to drain for 5 - 10 minutes. This provides a wet start-up of the
pump and removes any air in the system.
Turn the ON/OFF button on the machine to the OFF position.
Re-energize the pump power and trigger the ON/OFF button on the machine to check
rotation of the pump motor. Observing from the back of the pump motor, pump
rotation should be clockwise. If rotation is wrong, de-energize the pump voltage from
the source and switch any two of the three-phase wires coming in on top of the
