technicians. Incorrect and / or careless execution of these steps can lead to irreparable damage to the
membranes.
4.14 REPLACE MEMBRANES
1. Turn off the reverse osmosis and pull the plug out of the wall socket
2. Make sure the entire system is pressureless. Then disconnect the pipes at the entrance and the outlet
of the membranes.
3. Carefully remove the end caps.
4. Pull the membrane out of the membrane holder. You may also need to remove the end cap at the
bottom to be able to push against the membrane from below.
