CAUTION

Before starting any filter system, be sure the pump has been adequately primed by filling the strainer on the pump with water.
Failure to do so will result in pump seal problems. When installing in conjunction with a heater, a one-way check valve

should be used between the filter and heater to prevent the backflow of hot water from damaging the filter internals.

B. WHAT IS DIATOMACEOUS EARTH AND HOW DOES IT FILTER WATER?

1. Diatomaceous earth is the skeletal remains of microscopic one-cell aquatic plants called diatoms, also known as
diatomite, D.E., and more properly diatomaceous earth.

2. Under the microscope, these minute diatoms show an amazingly intricate design and variety of forms, such as disc­shaped, boat-shaped, needle-like and many have a lace-like porous structure.

3. When used as a filter aid, the diatomaceous earth is mixed with water to form a slurry for filter 'precoat'. This
mixture is introduced into the filter system by means of a slurry pot, or by pouring directly into the surface skimmer
with the pump running. The minute diatoms are deposited on the outer surface of the filter elements, forming a
'strawpile' layer or cake by interlacing and overlapping, and thus providing countless microscopic channels which
entrap suspended impurities, but allow clear water to pass through without clogging.

4. We recommend the use of D.E. which is sold and labeled for use with swimming pools and spas. These grades of
D.E. typically have a median particle size of 34 microns, which is ideal for most applications.

WARNING

Diatomaceous Earth (D.E.) Precoat Requirements

Failure to operate your filter system or inadequate filtration
can cause poor water clarity obstruction visibility in your pool
and can allow diving in shallow pool area, or diving into or on
top of obscured objects which can cause serious bodily injury
or drowning.

C. FILTER PRECOATING INSTRUCTION:

1. Mix the Diatomaceous Earth in a pail of water to
form a slurry, then pour the mixture directly into the
surface skimmer with the pump running. Insure that
the right quantity of D.E. is used as shown in the
table.

* By Weight - 1 lb. of D.E. per 10 sq. ft. of filter surface area.
