FLUSHING THE SYSTEM
The system should be flushed weekly to remove sediment from the surface of the membranes. To
manually flush the system, follow the preceding steps:
1.
The system must be operating during the flush procedure.
2.
Fully open the concentrate valve. (Figure 1B, Page. 16)
3.
Allow the system to run for 10 to 20 minutes.
4.
After 10 to 20 minutes, close the concentrate valve to its previous setting. Ensure the proper
concentrate flow rate is going to the drain.
5.
The system is now ready to operate.
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.
Fully immerse the elements in the membrane housing in a solution of 2% M-100, venting the air
outside of the pressure vessels. Use the overflow technique: circulate the M-100 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 M-100 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 by closing all valves.
3.
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:
1.
Disconnect the inlet, concentrate, pre-filter, and permeate plumbing.
2.
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.
3.
Disconnect the tubing from the connectors on the permeate and concentrate inlets and outlets.
4.
Fully open the concentrate valve.
5.
Drain the flow meters.
6.
Allow the system to drain for a minimum of eight hours or until the opened ports quit dripping.
7.
After draining is complete, reconnect all of the plumbing.
