Figure 10. Sand Level

Figure 11. Automatic Vent Positioning

If used, pour pea gravel SLOWLY into the filter

first. Level the surface of the gravel, and then

pour in the appropriate amount of sand to the level

indicated in Table 2. If using sand only, pour it into

the filter SLOWLY to the level indicated in Table

2. Be careful not to dislodge the vent tubing from

its fitting in the piping while adding filter media.

Refer to Figure 10.

6a. For the JS60-SM: Swing the diffuser back so it is

centered with the lid hole in the tank top.

6b. For the JS100-SM: Remove the cardboard sand

deflector.

Wash away any sand or dirt particles in the threads

in the top of the tank.

Ensure diffuser(s) are upright and centered

properly.

WARNING

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 dam age.

3.6 Use of Zeobrite

Sand

As an alternative filter media for use instead of

sand, Zeobrite has been qualified for use in Jandy JS

series filters.

For filter sizes of 30" in diameter and greater, it is

recommended that a pea gravel bed be used before

adding the filter media. See Table 3 for the type

and amount of pea gravel to use. Ensure the top

surface of the pea gravel is flat before adding filter

media.

Using the correct pea gravel will ensure that the

filter media is evenly lifted during backwashing

cycles and settles evenly after backwashing to

optimize filter performance. The pea gravel will

cover the laterals to approximately 1" above the

laterals.

Fill the filter with Zeobrite to the level shown

in Table 3. The weight of the material shown is

approximate. See Figure 10 for the illustration of

"Freeboard".

3.7 Lid Installation

Follow these instructions carefully.

Improper lid installation can cause

product failure or also cause the filter lid

to be blown off, which can result in death,

serious injury, or property damage.

Never attempt to adjust or remove the

lid when the pump is running or there is

pressure in the system. This 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.

Ensure that the lid seal is fully seated within the

groove in the flange of the lid.
