3. Remove the tubing connections on the inlets and outlets of the membrane element
housings.
4. Open the concentrate valve.
5. Remove the drain plugs from all PVC manifolds.
6. Be sure the flow meters are drained by disconnecting the bottom fitting of each
flow meter.
7. Allow the machine to drain for a minimum of eight hours or until the opened ports
quit dripping.
8. After draining is complete, reconnect all of the piping.
4.6 Membrane Element Installation
NOTE: For machines with membrane elements not loaded at the factory, the fol-
lowing steps are to be used for installation.
CAUTION: The membrane element is packaged in a small amount of bactericide solu-
tion to prevent biological growth; provide adequate ventilation when han-
dling. The membrane element must be kept moist at all times in order to
prevent possible damage to the membrane element material.
STEPS
1. Remove the membrane element bag containing the membrane element from the
shipping tube.
2. Cut the bag open as close as possible to the seal at the end of the bag, so that the
bag may be re-used if necessary.
3. Remove the membrane element from the bag and remove the foam protectors from
each end of the membrane element.
4. Remove the parts from the parts container (if included) and inspect. Make sure that
all parts are clean and free from dirt. Examine the O-rings, brine seal, and perme-
ate tube for nicks or cuts. Replace the O-rings or brine seal if damaged. Set the
membrane element aside in a clean space and continue on to Step 5.
5. Remove the end caps from both ends of all membrane element housings on your
machine. This is done by loosening the clamp bolts at each end cap closure
assembly.
6. Determine the direction of fluid flow in the membrane element housing. (Be cer-
tain to look at the “Direction of Flow” arrow for each membrane element housing.
Direction of flow may vary within a given machine.)
