6.4 CHECK/REPLACEMENT OF OSMOTIC MEMBRANES
A decay of performance rating of 10% per year is considered normal wear for osmotic
membranes. Special conditions of entry water and/or high consumption may accelerate
the clogging of the membranes.
Close the mixing valve completely.
Supply water and verify permeate flow and conductivity with a reference tool.
If the capacity is reduced more than 50% of the initial conditions and/or the conductivity
is greater than 80μS/cm2, replace the osmotic membrane as follows.
Disconnect the pipes from the fittings of the vessel containing the membrane.
Remove the vessel from the machine and unscrew the caps.
Remove the membranes clogged and replace with new ones of the same type.
Clean the vessel on the inside by removing all traces of dirt and scale.
The new membrane must be unpacked immediately before their installation and handle
them using sterile protective gloves.
Before installing the membrane in the vessel, lubricate the o-ring and the upper seal.
Install the vessel with reverse procedure.
Supply water for at least 15 minutes, then check permeate flow and quality.

1) Per le dimensioni nominali minori di 0.5 [mm], gli scostamenti devono essere indicati vicino alle dimensioni nominali
1) If the nominal dimension is less 0.5 [mm] the limit of tollerance must be written near the nominal dimension
