GE EZ2 Series - Manual (Page 8)

Your RO is designed to operate on softened 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 chlo-
rine may cause irreversible damage to the Thin-layer composite (TLC) polyamide
(PA) membrane elements in your machine. Daily water checks are recommend-
ed to ensure the integrity of your pretreatment and RO system. Refer to
Table 2.2 (E2/EZ2-Series Feed Water Requirements).
2.8.2 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.
WARNING: IMPROPERLY FLUSHED PRETREATMENT MAY
CAUSE SERIOUS RO MACHINES PROBLEMS AT
START-UP.
WARNING: NEVER OPERATE THE MACHINE WITH THE CON-
CENTRATE OR PERMEATE LINES BLOCKED.
SEVERE DAMAGE TO THE UNIT MAY RESULT.
2.9 Machine Start-Up
STEPS
1. Turn the feed water supply to the machine ON, while checking for leaks in the
pretreatment and inlet feed water lines.
2. Check to ensure power to the motor is de-energized and the ON/OFF button, on
the machine, is in the ON position.
3. Plug in the factory-supplied power cord.
NOTE: Fifty (50) Hertz models require customer supplied plug compatible
with existing outlet.
4. For initial start-up, redirect the permeate and concentrate lines to the drain for
start-up flush.
5. Open the concentrate and recycle flow control valves two (2) complete turns.
These valves are positioned on the flow control plumbing (Figure 2.1, Flow
Control Center).
WARNING: ONCE MACHINE IS OPERATING, FLUSH CONCEN-
TRATE AND PERMEATE TO THE DRAIN FOR
20 - 30 MINUTES. FLUSHING ENSURES ALL BIOCIDES
AND CONTAMINATES ARE REMOVED FROM THE
MEMBRANE ELEMENTS.
