6. With a smooth and constant motion, push the membrane element into the housing so the brine
seal enters the housing without coming out of the brine seal groove.
7. Re-install the end plugs by gently twisting the end cap while pushing it onto the housing.
8. Ensure that you do not pinch or fatigue any O-rings while re-installing the end plug. Push the
end plug on until it is seated on the membrane and the top surface is flush with the grooved
rings.
9. Reinstall the two retaining plates by pushing them in against the hub and then sliding them
outwards until they seat in the grooved ring and are lined up with the tapped holes.
10. Reinstall the two M6x1.0x10 bolts that secure the retainer plates in place with a 5mm Allen head
wrench.
11. Reconnect any fittings that may have been disconnected when the membrane pressure vessels
were disassembled.
12. To Start-Up the system, please refer to the Initial Start-Up section of this manual on pg. 32
WARNING
THE BRINE SEAL MUST BE IN THE SAME POSITION FOR EACH MEMBRANE
ELEMENT HOUSING. THE BRINE SEAL IS A RUBBER SEAL THAT PROTRUDES ON
ONE SIDE OF THE MEMBRANE AND IS ALWAYS ON THE FEED SIDE OF THE
MEMBRANE ELEMENT.
CAUTION
Wet membranes are shipped in a preservative solution. The membranes must be flushed for at least
30 minutes prior to use to remove the preservative from the membrane. Discard all the permeate and
concentrate which is produced during the flush period.
NOTE
As time progresses, the efficiency of the membrane will be reduced. The permeate flow
rate will begin to decline slightly after approximately 1000 hours of operation but can be
extended with diligent flushing and cleaning of the system. A high pH and/or precipitation
of hardness can cause premature loss in rejection of membrane elements in the system.
NOTE To get best results from the system change the membranes every 1,000 hours.
