Q-SERIES Cartridge Style D.E. Filter Installation and User’s Guide
Preparing Diatomaceous Earth (D.E.)
Your filter requires diatomaceous earth (D.E.) for
proper filtration and operation. Your filter cartridges
must be precoated with this material in order to protect
their surfaces and provide the most efficient filtering
action. Refer to
Table 2
for the proper quantity to use
with your filter. 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.
1. The filters are listed with the appropriate amounts
of D.E. to be used to precoat the filter cartridges.
A 1-lb. coffee can filled (level) with D.E. is equal to
1/2-lb. weight of diatomaceous earth. Do not “pack”
or compress D.E. into the coffee can.
2. Mix the required amount of D.E. with sufficient
water in a bucket to make a thin, milky mixture.
3. Refer to
Coating the Filter Cartridges with D.E.
for
instruction on introducing the D.E. slurry into the
filter.

Coating the Filter Cartridges with D.E.
The following information should be read
carefully since it outlines the proper manner
of care and operation for your filter system. You can expect
maximum efficiency and life from your filtration system by following
these instructions and taking the necessary preventative care.
1. Position valve to FILTER OR VACUUM TO POOL
setting. This is your normal flow from the pump
through the filter to the pool. Open the HiFlow™
Manual Air Relief Valve on the filter.
2. Prepare the recommended amount of
diatomaceous earth according to instructions given
in
Preparing Diatomaceous Earth (D.E.)
.
3. On initial start-up the pump must be primed by
filling the hair and lint strainer pot with water. You
may have to do this several times.
4. Follow the steps outlined on page 8,
Start-Up
Instructions
for system start-up.
5. Introduce the slurry of D.E from the bucket directly
into the top of the skimmer. With the pump running
and the pool skimmer valve open, pour the mixture
directly into the skimmer. The slurry will be drawn
into the filter.
6. Your filter is now operational.
Follow all manufacturer safety precautions given on
the D.E. packaging.
