To Install a Replacement SwimPure System:
Shut off the pump.
If the filter is located below the water level, close valves (or
block off suction and discharge lines) to prevent backflow of
water from the pool.
Unscrew and remove drain plug and allow water to drain
from the filter.
Remove filter control valve clamp.
Remove filter control valve. Note: Hoses can remain
attached to the valve.
Remove old purifying system by pulling upward on the
system. A slight twisting motion may ease its removal.
Properly place new purifying system onto the center pipe
with the side showing “SwimPure by HAYWARD” facing up.
Wipe the filter flange clean.
Insert the filter control valve (with valve/tank O-ring) into the
tank neck, ensuring that the bottom port of the valve slips
over the top tube of the SwimPure system.

5. ACTIVATE THE SYSTEM
Run the pump and filter system 24 hours per day for 4
days
- OR:
Run the pump and filter system 6 hours per day for 14
days.
NOTE: Maintain 1-2 ppm residual chlorine level
throughout the 4 day or 14 day activation period.
6. Let the chlorine residual drop to 0.4-0.6 ppm when the
system activation period is complete.

Reinstall filter control valve clamp, following these steps:
Loosely pre-assemble both halves of the clamp with one
screw and one nut, turning the nut 2 or 3 turns.
Install clamp around tank and valve flange, and assemble
second screw and nut.
Tighten both sides of clamp alternately and evenly. Use a
proper-sized large screwdriver and tighten firmly to obtain a
good seal.
Be sure to place vinyl protector caps over ends of screws.
NOTE: If your filter has an SP0704 valve with a serial
number ending in numbers 29 or higher, or 628, H28, J28,
K28, L28, or M28, you can use the center pipe extension
“as-is.” For other SP0704 valves, please cut 1” off of the
top of the center pipe extension (narrow end).
2. BALANCE THE POOL WATER
All swimming pools require properly balanced water. Refer to
the chart below for required chemical levels. Consult your
dealer for specific water balance instructions.
Important: The pool water must be balanced before using the
purifying system. Failure to balance the pool water may cause
staining of the pool and/or may shorten the SwimPure system’s
useful life.
Depress Vari-Flo control valve handle and rotate to
Recirculate position.
Prime and start the pump according to pump instructions
allowing the filter tank to fill with water. CAUTION: All
suction and discharge valves must be open when
starting the pump. Failure to do so could cause severe
personal injury and/or property damage.
Operate the filter in the “Recirculate” position while chemical
additions are made until the water is balanced. In this
position water is recirculated through the pool, bypassing the
filter and SwimPure system.
After water is balanced, turn off pump and set Vari-Flo
control valve to Filter position.

Important: Your SwimPure Retrofit Kit comes with a center
pipe extension. It is provided should you decide to operate
your sand filter without the SwimPure. Please keep it in a
safe place. If later you decide to operate your sand filter
without the SwimPure, simply take out the SwimPure
system from your filter and put the center pipe extension
on top of the center pipe before you install the valve.
3. RECORD INSTALLATION DATE
Important: Record the installation date of your
SwimPure system on the label provided with your
SwimPure system. Make sure the label is placed on the
body of your filter. Replace the SwimPure unit after six
months.
Replacement Interval
In frost-belt regions (3-6 month season):
Discard your used system and install a new system when you
open your pool in the spring.
In sun-belt regions (7-12 month pool season):
Replace the system every 6 months whether or not you plan
to use the pool for swimming.
Important: Your SwimPure replacement unit comes with a
label. Record the installation date of the unit on the label
and place the label on the body of your filter. Replace the
SwimPure unit after six months.

How Often:
Every Day
Once a Week
As Needed
As Needed
What to do:
Run pump and operate filter system at
least 6 hours daily.
Balance pH and Total Alkalinity.
Check chlorine residual: add chlorine to
maintain 0.4-0.6 ppm residual.
If the water starts to look hazy, super-
chlorinate (“shock”) using 1 lb. of chlorine
granules or 1 lb. of non-chlorine oxidizer per
10,000 gallons of water. Add cyanuric acid to
maintain 50 ppm. Please seek to reduce
your chlorine level by 50% to 80% versus
the chlorine levels you would maintain
without the SwimPure purifying system.
MAINTENANCE
Follow the maintenance schedule below:
4. SUPER-OXIDIZE OR “SHOCK” THE POOL
On the first day, super-oxidize the water with 1 lb. dry, or 1
gallon of liquid chlorine, per 10,000 gallons of water to burn
off contaminants and to activate the purifying system.

Troubleshooting Guide
Problem What To Look For Treatment
Cloudy Water
Algae
Algae may be
caused by
insufficient
levels of
oxidizer
and/or
inadequate
water
circulation
Poor filtration 1. Backwash & clean filter.
2. Run filter for 24 hours.
3. Increase run time per day.
Superchlorinate water (with
dealer’s guidance) and brush
pool walls. See treatment for green
algae below.
NOTES: Regular algaecide treatments are recommended for outdoor pools that experience persistent algae problems.
Do not use algae treatments containing either copper or sodium bromide.

Slow filter turnover rates.
Hazy pool water; may have
slight green appearance
Algae growth
Unbalanced water
Green algae
Black algae
Mustard algae
Black spots on pool walls
Yellow or brown
film on steps or walls.
1. Brush affected areas.
2. Shock pool with chlorine.
3. Add algaecide.
4. Vacuum pool.
5. Repeat steps 1-4 until algae is
gone.
6. Backwash filter.
Pea green color;
attaches to pool walls;
sometimes colors the entire
body of water.
1. Check pH and adjust if necessary.
2. Shock pool with chlorine.
