3.EN60335-2-41 TEST standard requires the sand filter must
be vertically fixed on ground or a certain pedestal made of
wood or concrete before use to prevent the sand filter from
accidental falling. Fully assembled sand filter will exceed
18 kg. The mounting holes should be 8 mm in diameter and
spaced 86 mm apart. Use two bolts and nuts with a maximum
of 8 mm in diameter to fasten the sand filter to the pedestal.
Load pool-grade filter sand/Flowclear™ Polysphere.
NOTE: Use only special pool-grade filter sand, free of all
limestone or clay: #20 Silica sand 0.45-0.85 mm, approximately
one 45 kg bag should suffice. If you do not use the recommended
size of filter sand, filtering performance will be reduced and the
sand filter may damaged, thereby voiding the warranty.
IMPORTANT: We suggest using #20 silica sand with your
pool sand filter. It is specially graded to trap particles in the
20 - 100 micron range.
Some small debris can pass throw the sand and back into
the pool. This is normal, especially if the debris is fine or silt.
To limit this, it is better to follow the maintenance
instructions, and backwash and rinse when necessary.
We also suggest contacting your pool dealer for the
chemical product specifically made to clean the sand. The
correct maintenance of the sand will optimize the cleaning
efficiency and avoid accumulation of oils or scale.
When you are vacuuming the bottom of the pool that has a
large amount of debris, we suggest to backwash the sand
when you finish cleaning half of the pool.
Remember to backwash and rinse the sand after
vacuuming the bottom of the pool each time.
NOTE: To avoid damaging the Skimmer when adding
sand, pour some water into the Bottom Tank to submerse
the Skimmer on the Hub.
NOTE: Sand/Flowclear™ Polysphere not included.
NOTE: Use 28 g (0.06 lbs) Flowclear™ Polysphere to
replace 1 kg (2.20 lbs) sand.
