How do you change the sand in Hayward S200 filter?

Loading sand media. Filter sand media is loaded through

the top opening of the filter.

Remove the top diffuser from the internal diffuser

elbow pipe and place flexible automatic air relief tube

to the side, out of the way, inside the tank.

Cap the internal diffuser elbow pipe with sand shield

provided to prevent sand from entering it.

It is good practice to fill tank approximately 1/2 way

with water to provide a cushioning effect when the filter

sand is poured in. This helps protect the underdrain

laterals from excessive shock. (Be sure the drain cap

is securely in place on drain pipe. Apply wrench to flats

on pipe when tightening cap.) Note: Check to

confirm all laterals are in the down position before

loading with sand. (See Figure A on Page 2.)

Carefully pour in correct amount and grade of filter

sand, as specified. Sand surface should be leveled

and should come to about the center of the flange of

the filter tank. Use no more than the recommended

amount of sand.

Remove sand shield from internal diffuser elbow pipe.

Replace diffuser on internal diffuser elbow pipe,

positioning automatic air relief tube through the hole

provided in the diffuser. Align tab on diffuser with slot

in pipe and gently press down.

Carefully clean off top seal O-ring and screw access

dome, with manual air relief, securely into the filter

head.
