concrete slab. Position the sand filter so the Ports and
Control Valve are accessible for operation, servicing and
winterizing.
3. EN60335-2-41 TEST standard requires the sand filter to be
vertically fixed on ground or a certain pedestal made of wood
or concrete before use to prevent the sand filter from
accideutally 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 20 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.
