PREPARING UNIT FOR STORAGE OR SHIPMENT

Prior to shipping or storing your system, the system should be cleaned with an

appropriate cleaner, flushed with water, and protected from biological attack with an

appropriate solution for membrane elements. The membrane housing(s) and plumbing

lines of the system must be completely drained. Any water remaining in the plumbing of

a system may freeze, causing serious damage.

Preparing system for storage:

1. Totally immerse the elements in the membrane housing in a solution of 2 %

Memstor, venting the air outside of the pressure vessels. Use the overflow

technique: circulate the Memstor solution in such a way that the remaining air in

the system is minimized after the recirculation is completed. After the pressure

vessel is filled, the Memstor solution should be allowed to overflow through an

opening located higher than the upper end of the highest pressure vessel being

filled.

2. Separate the preservation solution from the air outside. Any contact with oxygen

will oxidize the Memstor.

3. Check the pH once a week. When the pH becomes 3 or lower, change the

preservation solution.

4. Repeat this process at least once a month.

During the shutdown period, the plant must be kept frost-free, or the temperature must

not exceed 113°F (45°C).

Preparing unit for shipment:

5. Disconnect the inlet, concentrate, pre-filter, and permeate plumbing.

6. Drain all water from the pre-filter cartridge housings by unscrewing the housings,

removing the pre-filter cartridges, and drain the water from the housings.

7. Disconnect the tubing from the connectors on the permeate and concentrate

inlets and outlets.

8. Allow the system to drain for a minimum of eight hours or until the opened ports

quit dripping.

9. After draining is complete, reconnect all of the plumbing.
