PREPARING UNIT FOR STORAGE OR SHIPMENT
Prior to shipping or storing the 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 re-
maining in the plumbing of a system may freeze, causing serious damage.
Preparing system for storage:
1. Totally fill membrane elements in the membrane housing with 2 % M-100 solution,
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.
2. Check the pH once a week. When the pH becomes 3 or lower, change the preser-
vation solution.
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:
4. Disconnect the inlet, concentrate, pre-filter, and permeate plumbing.
5. Drain all water from the pre-filter cartridge housings by unscrewing the hous-
ings, removing the pre-filter cartridges, and drain the water from the housings.
6. Disconnect the tubing from the connectors on the permeate and concentrate inlets
and outlets.
Allow the system to drain for a minimum of eight hours or until the opened ports quit
dripping.
After draining is complete, reconnect all of the plumbing.
