Ro Membrane Installation - A.O. Smith LOTUS-75M User Manual

• RO Membrane installation

-Installation of the regular RO Membrane:
First take the water purifier out of its package. Open the water purifier's
outer cover. Unscrew the membrane shell cover inlet water connection
and take out the inlet water pipe. Then use the membrane shell wrench
to unscrew the membrane shell cover. Take the RO membrane out from
its package. Place the end of the membrane with the O-ring into
Waste water
• Membrane Installation Warnings:
• The package of the reverse osmosis membrane contains a small amount
of protective solution in order to prevent microbiological contamination
of membrane components during storage and transportation.
• You should pay attention to the direction of the RO membrane during
installation.
• When installing the RO membrane; you should first make sure that one
end of the membrane has an O-ring;
• During installation, be sure to put the end with the O-ring into the end
of the membrane shell with the pure water connection. If you install
the reverse osmosis membrane correctly, you will only need a little force
to mount it into the membrane shell. If you encounter too much
resistance, please do not force the reverse osmosis membrane into
the membrane shell. Doing so may cause permanent damage to the
membrane shell or membrane components (the membrane
manufacturer does not assume responsibility for returned components
due to damages incurred during installation).
• Damage to the membrane shell and reverse osmosis membrane
components inflicted as a result of the abovementioned reasons is not
covered under the water purifier's warranty.
• Do not cut or try to disassemble the replaced membrane. RO membrane
can filter microorganisms and cutting or harming RO membrane may risk
on you and your environments health.

the reverse osmosis membrane shell (See Diagram 9) and push it in.
Finally, screw the membrane shell cover back on and use the membrane
shell wrench to tighten the membrane shell cover. Connect the inlet water
pipe into the inlet water connector on the membrane shell and screw in
the nut. Place the membrane shell card into the large single clip available
and attach the water purifier cover back on.

• Installation of the pipes
- Before installing the pipes, make sure that the surface of the pipes is
smooth. Cut the pipe on the front-end perpendicular with the length
of the tube with scissors and then make the cut section round before
inserting inside (see diagram 10 for the correct way of cutting);
If the pipe is not round, but still elliptical and then is inserted inside,
it will damage the O-ring and cause water leakage.
- While installing the water pipe, it will get stuck at the first bayonet
before the pipe is completely seized by the connectors. Push it hard
until the pipe reaches the end. If the pipe cannot be inserted into the
deepest end, it probably breaks away when transferring the pressure.
(see diagram 11)
- When removing the water pipe, push in the jack catch first and then
pull out the pipe (see diagram 12).
- After the water pipes have been connected, safety clips should be
installed on the quick fittings to avoid the fittings to break away.
