4. ASSEMBLING INSTRUCTIONS
4.1. ASSEMBLING OF MODULES:
The sequence for the assembling of modules is described below:
STEP DESCRIPTION GRAFICAL SCHEME
1
Screw in completely the assembling supplements,
by the M6 end, in the upper plate of the module.
Upper plate of the module: with the module in
vertical position, upper part with respect to the
identification label
(Orange pieces)
2
Install the back-plate which has the holereductions, turned over 180º respecting its
permanent position. It must have the holereductions next to the plate, fully in contact with
the assembling supplements.
(Pink piece)
3
Fix the assembling supplements with the
corresponding M5 washers and nuts.
(Yellow pieces)
4
In horizontal position of the module, insert
carefully the ceramic membranes by the opposite
side, until reaching the stop in the back-plate
previously installed. Membranes must be inserted
from the bottom to the top.

DESCRIPTION GRAFICAL SCHEME
5
After installing the membranes, put the second
back-plate (without hole-reductions). Use the Orings and mounting screws M6.Torque approx.
10 Nm. Membranes must protrude approx. 4 mm
from the plate.
The screws must be tightened crosswise. Since
this operation allows the O-rings to be tightened
and provides the water-tightness of the module, it
must be done carefully and uniformly.
NOTE: only one membrane is represented in the
picture.
6
Release the initially installed back-plate (with
hole-reductions), turn it over 180º and repeat the
instruction 5. Membranes are now mounted in the
housing.
4.2. ASSEMBLING OF MODULES:
•
After unscrewing the screws in the back-plate of both sides, back-plates must be extracted carefully. Sometimes, back-plate
can be stuck to the plate due to the high operating pressure. For these cases, the back-plates have some M5 threaded holes
(marked with arrows in the picture below) where screws can be inserted and used as extractors, so that when they are
tightened, pressure is applied on the plate and the back-plate is extracted from the housing.
• After removing the back-plates from both sides, remove the O-rings from one side carefully (Don’t use Sharp tools).
• Remove the membranes from the side where the O-rings are still present. Be careful: membranes are just hold at the tips of
the module.

4.3. OTHERS
It is recommended NOT to reuse the O-rings.
If substantial vibrations are thought to occur, it is recommended to use fixing glue for screws.
Tools for manipulation/elevation of housings must be available for manipulating heavy modules.
5. WARRANTY
Unless there is an explicit contractual specification that modifies the general warranty conditions, Likuid modules are guaranteed
against all manufacturing or assembling faults for a period of 12 months from the starting-up, or 15 months from the date of
purchase.
