IONPURE

4 Getting Started

4.1 Initial Startup

The startup sequence depends on the design of the CEDI system. Please consult the Operation
Manual for the CEDI system.
The following startup procedure is only an example for a typical single module CEDI system:
1. Close the main disconnect switch (or circuit breaker) for the CEDI system.
2. Open the appropriate valves and start the pretreatment equipment, such as the reverse
osmosis (RO) system, upstream of the CEDI system.
3. Adjust the flow rates of the dilute and concentrate streams through the module.
4. For each operating channel on the G2 display, enter the RUN submenu and adjust "A
DC out" to set the DC output current to the value calculated by the Ionpure Performance
Projection Program (Current Startup Calculator). The power controller will maintain the
current at that setting if the required voltage to drive the current is lower than the
maximum DC voltage available.
5. Verify that the DC output is removed when the CEDI module flow is interrupted.
Operation with DC power on and insufficient water flow can cause
irreparable damage to the CEDI module(s) and system.

4.2 Output Current Adjustment

The DC output current may need to be adjusted if there is a change in feed water conditions and/or
flow rate.
