System Startup And Flushing Process; Prefilter And Mineral Addition Flush And Tank Fill - Pentair EVERPURE EZ-RO 200/2G Installation & Operation Manual

SYSTEM STARTUP AND FLUSHING PROCESS

PREFILTER AND MINERAL ADDITION FLUSH AND
TANK FILL
1. Install prefilter into far left position and mineral
addition cartridge in middle position. Align cartridge
lugs with heads in bracket. Press up and twist a
quarter turn.
2. Make sure the membrane plug is installed.
The processor comes with a pre-installed standard
reject flow restrictor (white). Water conditions and RO
membrane filter size will determine what color flow
restrictor may be required to have your EZ-RO system
operating the most efficiently.
Record the feed water conditions of incoming TDS (total
dissolved solids) measured in ppm (parts per million)
and the incoming water pressure measured in psi.
Then see the "Reject Flow Restrictor Chart" on page 10.
Follow chart per system size EZ-200 or EZ-375.
If the chart recommends using the white flow restrictor,
skip steps 3 through 6.
3. The reject flow restrictor that will need to be
replaced is located on the left side of the 1/4" Tee
fitting on the top of the processor connected to the
black tubing.
4. Press the gray collet into the fitting and pull the left
black tube away from the 1/4" Tee fitting. Pull out
the white capillary flow restrictor. This task may
require small pliers.
5. After reviewing the "Reject Flow Restrictor Chart"
on page 10, choose from the bag located with the
manual the color of flow restrictor that best fits
your water requirements. Colors included: green,
blue, gray. (White is pre-installed.)
6. Insert the selected flow restrictor into the 1/4"
black tubing. Firmly insert black tubing into 1/4" Tee
fitting. (Reference "Using Push-to-Connect Fittings"
on Page 7.)
7. On tank, close valve to shutoff position.
8. Open the reject flush valve.
It's the side middle blue handle.
Open = pointing down.
9. Check to make sure the permeate sample port valve
is in closed position.
It's the side bottom blue handle.
Closed = pointing left.
10. Turn the front handles to the following positions:
Inlet valve—top black handle pointed down (open).
Outlet valve—bottom black handle pointed to right
(closed).
