Cartridge Style D.E. Filter Installation and User’s Guide
Coating the Filter Elements with Diatomaceous Earth (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.
When Using Slide Valve:
1. Twist to unlock plunger, then raise the handle as far as it will go. Turn handle clockwise to lock lower pin in
underside of cap.
When Using Multi-port Valve:
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 High Flow™ Manual Air Relief Valve on the filter.
2. Prepare recommended amount of diatomaceous earth by mixing it with water in a bucket until it is the
consistency of milk; see page 5,
Preparing Diatomite
.
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 5
,
System Restart Instructions
for system start-up.
5. Introduce the slurry of diatomite 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. Note the original starting pressure on the gauge and record it in
Table 3
.
Note:
When using a variable speed pump the “Original Starting Pressure” will be dependent on the pump speed
(RPM). When recording the original operating pressure, also record the “Original Pump RPM” in
Table 3
.
7. Clean your filter when pressure reads between 10 to 12 psi
higher than the original starting pressure. Your filter pressure
reading will increase as it removes dirt from your pool.
However, this build-up of pressure will vary due to different
bathing loads, temperature, weather conditions, etc.
Note:
Pressure build-up varies due to different bathing loads,
temperature, environmental conditions, etc.
Note:
If the starting pressure after backwashing the filter
or cleaning the elements indicates 4 to 5 psi higher than
the normal starting pressure, the filter elements must be
cleaned. Refer to page 7,
Manually Cleaning the Filter
for
instructions.
