Filter Assembly - Astralpool CLARITY Manuel D'installation

6.3 FILTER ASSEMBLY

Before assembling the filter, carefully clean and inspect tank and O-ring groove, either at the upper as at
the lower part of the filter, checking tahat there are no fissures or damages. If necessary, lubricate O-ring
with silicone oil.
Put the O-ring in the lower tank shell
Carefully push the upper tank shell over the lower one to compress the O-ring, checking that the O-
ring has not moved.
Insert the clamp and alternately tighten the nuts little by little, checking all time that the upper tank shell
is centred and clamp is tightening correctly.
6.4 GRID ASSEMBLY CLEANING PROCEDURE
At least once a year, it is recommended to completely dismantle the filter to remove algae, body oils and
calcium or magnesium deposits from the grids. Cleaning best before ending season.
Run a complete filter, Backwash", according to section 6.1
Disassemble filter acording to section 6.2
Pull top mounted manifold to remove grid assembly.
Unscrew the manifold nut and remove grids and internal air bleed assembly. Pay attention to grids
position at supporting grid as one of the 8 grids is smaller ( See fig. 6).
Clean air bleed assembly and grids using a soft brush and industrial detergent.
If necessary, leave grids to soak for several hours. Put every grid into a separate tank and soak with a
commercial filter cleaner. Follow cleaner manufacturer's instructions carefully.
Rinse using plenty of water at low pressure.
To assemble grids easily, put manifold inverted on the ground. Softly insert grids in the manifold
grooves, considering the position of the smaller plate.
Place the supporting grid over the 8 grids. Introduce the tie rod. Turn over the assembly, put the
washer and thread nut softly. Check all grids are placed correctly. Tighten nut slowly. Do not
overlighten.
Put the air bleed assembly.
Introduce the grid assembly into the filter by pushing the manifold softly in order to introduce it into the
pipe.
Assemble filter acording to section 6.3.
When very cold weather conditions, after Grid assembly cleaning proçedure" drain all water from
installation and cover filter.
