1.
Sand density can vary depending on the sand
and how much moisture it is carrying. For this
reason, consider the sand weights given in
Table 1 as approximation only. The free board
distance is the most important variable and
should be maintained.
• If pea gravel is used, it will cover the laterals
to approximately 1" above the laterals. See
Figure 2.
• All media to be marked as meeting NSF
requirements for sand filters.
• Sand is to be #20 Silica Sand (.016"-.021").
• Pea gravel, if used, is to be 1/8" to 1/4"
diameter range.
• Before adding any filter media, ensure the
laterals (spokes) are screwed firmly into the
hub and that the hub is centered in the tank
with the laterals (spokes) horizontal. Check
for any broken laterals (spokes) which may
have been accidentally damaged by rough
handling during shipment. Replace any
broken parts if necessary.
2.
Fill the filter halfway with water before loading
the filter media. See Figure 2.
3.
Cover each of the diffusers with a plastic bag.
• Care must be taken so that filter media does
not get into the diffusers.
• Take care not to dislodge the vent tubing and
vent screen. See Figure 7.

To avoid damaging the laterals (spokes), slowly add the filter media
until the laterals are fully covered. Cracked or broken laterals
(spokes) will cause sand to be discharged to the pool.
The automatic vent screen and tubing must be positioned properly
to avoid trapping air inside the filter. Trapped air can cause product
failure or also cause the filter lid to be blown off, which can result in
death, serious personal injury, or property damage.
4.
Use a small scoop and pour pea gravel SLOWLY
into the filter.
5.
Level the surface of the gravel, 1" above laterals.
6.
Use a small scoop and pour in the appropriate
amount of sand according to the level indicated
in Table 1.
7.
If using sand only, use a small scoop and pour
it into the filter SLOWLY to the level indicated in
Table 1.
8.
Remove and coverings from the diffusers.
9.
Check to ensure the vent tubing is appropriately
positioned in the tank. See Figure 6.
10. Using water only, rinse away any sand or dirt
particles in the threads in the top of the tank.
11. Ensure diffuser(s) are upright and centered
properly.
12. Make sure that the automatic vent tubing is in
place (threaded through the diffuser) and the
vent screen is installed at the top of the vent
tubing. See Figure 7.
