• The PURACHLOR BLU / GOLD must be installed and operated as specified
in the Owner’s Manual.
• Power to the PURACHLOR BLU / GOLD should be turned off before unplug-
ging the electrolytic cell from the cell housing to prevent cell damage and low
voltage sparks. Scratching or bending plates in the cell housing will reduce cell
life.
• DO NOT use any type of lubricant on the O-ring. The O-ring (and the chan-
nel it seats into) must be kept clean in order to make a strong seal.
• High water temperatures above 40° Celcius (104 ° Fahrenheit) or direct
sunlight can cause the cell housing exterior plastic to discolour. This is not a
warranty claim.
• Follow Installation Instructions on page 7 for location and mounting of the
Control Centre.
• Visibly inspect the cell frequently to check and prevent the accumulation of
pool debris that (for any reason) may have bypassed the pool filter.
• Direct sunlight can cause the Control Centre cover to discolour. This is not a
warranty claim.
The PURACHLOR BLU / GOLD must be installed by a qualified pool profes-
sional, certified electrician or authorised PURAPOOL® representative.
IMPORTANT WARNINGS & SAFETY INSTRUCTIONS
FAILURE TO HEED THE FOLLOWING COULD CAUSE
DAMAGE TO POOL EQUIPMENT OR PERSONAL INJURY
Page 3

INSTALLATION PROCEDURE
INSTALLATION LOCATION
a. It is recommended to install the electrolytic cell as the last piece of pool equipment
in line, on the return to the pool, after the heater. (See Figure 1 on page 6)
b. Installing horizontally will ensure the flow sensor remains submerged.
c. If installed vertically, the cell cap must be on top.
d. Always use a check valve before the cell to prevent chlorine backflow.
e. All fittings are 2 inch socket.
f. Do not install on pools using a stainless steel liner or stainless steel plumbing.
BELOW GRADE (GROUND) INSTALLATION:
g. This exists when the water level of the pool is above the height of the pool equip-
ment.
h. The system should be wired to the load side of the time clock to power on ONLY
when the primary pump is operating. Alternatively, plug the pump power cord directly
into the power socket on the PURACHLOR BLU / GOLD.
i. If valves are not present to isolate the equipment, one ball valve should be installed
on the inlet side of the cell. This allows the cell to be removed for cleaning when
necessary.
j. A one-way check valve should be installed on the outlet side of the cell. This will
eliminate the possibility of having a gas build-up (which could cause possible cell
damage.)
Failure to follow proper below grade installation
procedures may lead to damage to pool equipment.

ELECTROLYTIC CELL INSTALLATION PROCEDURE
a. Locate pool return line after the heater or filter as shown in ( Figure 1 page 6 )
This is the preferred location for the cell housing.
b. Cut and glue the vertical plumbing risers from the main plumbing into place.
Install union nut and tailpiece onto pipe. Install the cell housing to the top of the
risers, making sure the cell housing is level.
c. Install the O-ring into the receiving channel inside the cell housing and then slide
the cell into the cell housing making sure the key way on the black plastic base aligns
with the matching key in the cell housing.
d. Put the main cap into place and hand tighten only; be sure not to strip the threads.
e. Connect the cell cord to the Control Centre. Align the three pins of the cell cord
plug with the snapfit connector on the Control Centre base and insert the connector
until it clicks in place. Alternatively if you have a junction box model, connect and
screw the 3 colour coded wires directly to the 3 postion junction box.

Page 8
INSTALLATION PROCEDURE
a. Balance your water chemistry according to the Water Chemistry Parameters (see
Table 1). Add the proper amount of salts and circulate 36 hours before starting the
PURACHLOR BLU / GOLD
b. Start system at the 80% Chlorine output level and operate normally. For the first
two weeks test the water every 2-3 days for proper sanitation residual levels. Raise or
lower the Chlorine Output by pressing the Output Control Arrows as needed. See
Operation Instructions on pages 12-14.
c. If sanitation residuals are still below the 1-3 ppm range, PRESS the 18hr BOOST
button. See Troubleshooting on pages 17-18.
d. The rule of thumb for daily runtime of the PURACHLOR BLU / GOLD system (with
balanced water and running at >70% production) is;
1 hour of operation for every 3°C of ambient temperature.
(i.e. 30°C would equal 10 hours of run time).*
* For high humidity conditions, irregular flow rates,undersized pumps/ filters or
variable speed pumps add 2 hours to runtimes. (e.g. Asia, Africa, South America)
e. Once Chlorine Output percentage setting is set, output should only be adjusted for
increased sanitation demand situations.
PARAMETER LEVEL DETAILS
FREE CHLORINE 2.0 - 3.0 ppm
pH 7.2 - 7.6
TOTAL ALKALINITY (TA) 90 - 130 ppm Protects pH and prevents rapid pH "bounce".
CYANURIC ACID / STABILIZER 30 - 50 ppm Protects chlorine from destruction by sunlight.
Must be added manually.
CALCIUM HARDNESS 200 - 400 ppm
PHOSPHATES ZERO
SALT RESIDUAL 3500 - 5000 ppm Ideal level for Chlorine production.
Recommended level for residential pools to
keep chlorine at a proper range for sanitization
High pH reduces sanitizer efficiency. Low pH
damages pool surfaces and irritates skin and eyes
Excess calcium can increase scaling problems.
Low calcium (soft water) can damage surfaces)
Can deplete free available chlorine.
Table 1: Water Chemistry Parameters

SALT REQUIREMENTS
HOW THE PURACHLOR BLU / GOLD WORKS
At System Start Up the pool water should have a 3500-5000 ppm salt residual. As
part of the daily filtration cycle, the pool water is passed through the PURACHLOR
BLU / GOLD electrolytic cell to produce chlorine which is instantly dissolved into the
water. The PURACHLOR BLU / GOLD destroys bacteria, viruses and algae. When the
chlorine is spent it reverts back into dissolved salt, restarting the cycle.
WATER PREPARATION AND TIPS ON WATER CHEMISTRY
Pool water that is not maintained properly will cause damage to the electrolytic cell,
shorten the life of the cell and possibly void the cell warranty. Properly balancing pool
water chemistry is the most important aspect of maintaining a swimming pool. Pool
water must be tested regularly in order to properly maintain its chemical balance.
SALT REQUIREMENTS
a. The PURACHLOR BLU / GOLD operates best with a salt range of 3500-5000 ppm.
The cell will continue to operate with a minimum of 3000 ppm and up to 35,000 ppm
without any adverse effects to the unit.
b. NOTE: HIGH salt level above 8,000 ppm may cause corrosion problems with
metallic fixtures, light rings, ladders and handrails.
c. Salt level should be checked monthly. The salt level should never be allowed to fall
below 3000ppm.
Page 9

SALT REQUIREMENTS
HOW TO ADD SALT TO THE POOL
d. 2kg for every 1,000 litres of water will raise the mineral levels by100ppm.
e. Salt level is lowered through dilution (adding fresh water or rainfall), water
splashed out of the pool and/or backwashing the filter. Salt is not lost through
evaporation. If the salinity level drops below the recommended salinity range, use
Table 2 on page 11 to determine the amount of salts that has to be added to
obtain the proper salinity level.
f. Determine salt level as discussed above. Use Table 2 to calculate the amount of
salt needed.
g. Power on the pump to circulate the pool water.
h. Slowly pour in the salt around the outer perimeter of the pool for quick and even
distribution.
i. Brush the pool bottom to distribute the salt evenly and allow water to circulate for
36 hours to dissolve completely. After 24 hours, confirm salt level reading.
DO NOT attempt to add salts via the skimmer box or surge tank as this can cause
damage to the filtration system and the PURACHLOR BLU / GOLD.
DO NOT have any automatic suction type pool cleaners operating until the salts
have completely dissolved. Allow the salts to dissolve for 3-6 hours before initial
powering of the PURACHLOR BLU / GOLD.
j. Power on the PURACHLOR BLU / GOLD and set output percentage to desired
output level.

SALT ADDITION GUIDE
Use the below table to determine your current concentration of salt in ppm
and pool volume in litres. Find your desired salt concentration and add the
required amount of salt. e.g. a 40,000 Litre pool with a starting salt
concentration of 1000ppm will require 120kg of salt to raise to 4000ppm
