CAUTION

Be sure that all provisions for wastewater disposal

meet local, state or national codes. During any

backwashing or draining process, 100 gallons or

more of pool water will be discharged. Do not

discharge water where it will cause flooding or

damage.

3.5 Filling Filter with Sand

Jandy high rate sand filters most commonly use

sand as a filter medium, or sand over a shallow layer of

pea gravel. If pea gravel is used, it will cover the laterals

to approximately 1" above the laterals. The use of filter

media other than sand is also described in Section 3.6.

Sand density can vary depending on the sand and

how much moisture it is carrying. For this reason,

consider the sand weights given as approximation

only. Determine the actual amount of sand to add

based on Table 2.

Notes:

All media to be marked as meeting NSF

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.

CAUTION

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.

Add water to approximately 4" above the level of

the laterals.

4a. For the JS60-SM: Taking care not to dislodge the

vent tubing and vent screen, swing the diffuser

over to the inside of the tank to keep filter media

out of the diffuser while filling.

4b. For the JS100-SM: A corrugated cardboard sand

deflector is provided to keep sand or gravel out

of the diffusers when adding the filter media. The

sand deflector is provided in a flat form. To use

it, roll the cardboard up tightly to make a circular

tube and insert the tabs into the slots. Place it

inside the threaded top hole of the filter such that

the pop out tabs keep it in place until the addition

of filter media is completed.
