The location must have the proper space to allow
maintenance periodic overhauls and any other work.
Additionally the room must provide a drain to allow, in
case of accident, evacuation of water flowing from any
tube, filter, pump, etc. this will avoid risk of damages in
the electrical installations (pump, electric panels, etc.)
3.2
Filter Installation
Filters are delivered properly packed and ready in order
to facilitate unloading and transport using crane. It is
very important to make sure that the filters have not
suffered bumps during transport. Each package has a
number label which corresponds with the pair of the
stack set.
To obtain a correct filter installation, the following
stages must be observed:
-Install bottom filter on their final location. Make Sure
that the floor is leveled and all legs stand properly on the
floor.
-Put upper filter onto bottom filter as shown on photo.
Please carry the filters as intructed on 3.1 Handling of
this manual.
DO NOT PUT UPPER FILTER ONTO BOTTOM FILTER IF
BOTTOM FILTER IS NOT FILLED UP.
- Make Sure the holes of the legs correspond to each
other as shown on below photo.
-
Fix filters to each other with screws and nuts on every
bases.
-Install correctly the valve battery(ies) in the filters.
-Install battery supports and regulate them correctly
(height, etc.).
-Connect batteries with the delivery pipe of the pumps,
returns pipes and drain.
-Before filling, Check that the inner parts of each filter
(nozzles, collectors, top, diffusers) are in good condition
- First, fill minimum 1/3 of the bottom tank with water.
AFterwards, fill the bottom tank with gravel (1-3 mm )
and fine quartz sand. The filling must be made according
to the “SAND LEVEL” lavels on the
filters
-After the filling of the bottom tank, apply the same
filling sequence to the upper tank.
ALL GEMAS FILTERS ARE HYDRAULIC TESTED AT
PRODUCTION FACILITY. NEVERTHELESS, IT IS ADVISED
TO FILL THE TANKS WITH WATER AND TEST THE
SYSTEM AT SITE, BEFORE FILLING WITH MEDIA. THIS IS
A PRECAUTION TO OBSERVE ANY DAMAGES DUE TO
HANDLING, TRANSPORT ETC.
ATTENTION!
ALWAYS FINALIZE THE FIXATION OF THE BATTERY AND
PIPE SUPPORTS AFTER THE FILTER IS FILLED WITH
WATER. OTHERWISE, WEIGHT OF THE FILLED WATER
