Congratulations! You have purchased an Certikin S
SALT EXPERT Salt Chlorinator (V3) Page 3
1.0 General O er iew
ALT EXPERT series Chlorinator. Please
read the instructions carefully and your purchase ill provide you ith years of trouble free
use.
nverting some of the salt in your
pool into chlorine hich starts to destroy algae, bacteria and viruses in your pool ater thereby
sanitising your pool. As part of the process, the chlorine is converted back into salt and hence
salt is not consumed.
Your SALT EXPERT Chlorinator control has many features to ensure simple operation of your
chlorinator and filtration system. It has a clever Spa mode to ensure that the right level of
chlorine is produced hilst you are enjoying a spa.
Note: The Chlorinator is not intended for use by young children or infirm persons ithout
supervision. Please ensure that young children are supervised to ensure that they do not play
ith the Chlorinator.
2.1 Chlorinator Control Installation
The SALT EXPERT Chlorinator control has a Rating of IP24 enabling it to be installed
outdoors. Regulations require that the control is not allo ed to be located ithin 3 metres of
the pool ater.
The control should be installed in a ell ventilated position ideally a ay from direct sunlight.
Ensure that the unit is not located near pool chemicals as fumes may damage the control.
Included in the kit is t o green masonry plugs and scre s. When installing on a brick or
concrete all, use a 7mm masonry drill. Mounting Scre s should be 180mm apart and located
at least 1500mm above ground level. A drilling template is provided on page 6.
When installing the control on a post, first attach a flat aterproof panel at least 300mm ide
by 500mm long. Make sure the control is located centrally on the panel and sits flat.
Plug the plug into a suitable eatherproof outlet and then plug the pump into the Chlorinator
control.
Note: The pump current rating must not exceed 8 amps.
2.2 Cell Installation
The chlorinator cell must be located last in the pipe ork just prior to the return to the pool. If
valves are installed bet een the Chlorinator and the pool outlet, it is essential that they cannot
deadhead the pump. If the pressure in the cell exceeds 150kPa and/or the ater temperature
exceeds 40 degrees C, the cell may fail.
WARNING: Never install the cell before the pump or heater
The cell must be installed ith the barrel unions underneath and the cell should be horizontal.
50mm fittings have been provided. Make sure that the o’rings are correctly fitted and the
unions are done up tightly.

SALT EXPERT Salt Chlorinator (V3) Page 4
WARNING: It is essential that pipe ork and equipment do not allo gases generated from
the cell to collect and build up.
Once the cell is located, connect the black multi-core cable to the cell. The blue ire must be
connected to the blue terminal. The cable is designed to come from belo the cell. Make sure
ing nuts are correctly tightened to ensure good contact.
3.0 Pool Preparation
The chlorinator requires at least 3000ppm of salt but e suggest you prepare the pool at
4000ppm therefore add 4kg’s of salt for every 1000 litres of ater (a typical pool of around
50,000 litres requires 200kg of salt).
Salt should al ays be added at the shallo end of the pool and allo ed to dissolve. Running
the pump ill mix the ater and speed the dissolving process.
WARNING: Never add salt to the skimmer box!!
NOTE : Plug the pump directly into a po er outlet (bypass the Chlorinator) and run for 8-10
hours to ensure the salt is dissolved prior to running the chlorinator.
When the salt is dissolved, connect the pump to the chlorinator and run it on maximum chlorine
output. Check that the lo salt light is not on. If it is, check again in 24 hours.

or the morning and one for the evening
and typically for periods of 2-5 hours for each. Your chlorinator is most effective if running in
the early morning or evening hen it is cooler (strong sunlight consumes more chlorine). As a
default, the control is set to come on at 08:00 and 16:00 both for periods of 4 hours.
3.2 Chlorine Output
The Chlorine Output Control area of the user panel has three main functions:
(a) Increase/Decrease arro s for setting the chlorine output level of the chlorinator. The
chlorinator output can be set from levels 1 through to 8. This level only applies to Pool
Mode. When the Chlorinator is in Spa mode, the chlorine output ill be at level 1
(b) Chlorine Output display sho s the level set
(c) The LCD display ill also sho a output level from 1 to 8 hich indicates the
performance of the chlorinator compared to the Chlorine Output LED’s. Should the
LCD output level (1 to 8) be less than the LED output, check salt level in pool. Should
salt level be at 4000 ppm and output more than 2 settings less than LED display, you
cell may need replacing.

3.4 Warnings Display
Apart from messages displayed on the User display, there are t o arning indicators.
(a) LOW SALT: This indicates that the concentration of salt has reduced ithin you pool.
To rectify, add salt at approx. 50kg per 50000 litres of ater (see 3.5 Salt level belo )
(b) NO FLOW: This indicates that the Chlorinator thinks that there is no flo to the cells.
Potential problems/solutions are described in the Diagnostics section.

3.5 Chlorine Output Le el
The LED lights on the user panel set the desired output level or chlorine level.
As sho n belo , the bottom right hand corner of the LCD display indicates the actual level as
distinct from the set or desired output indicated by the LED lights.
The chlorinator output, or chlorine production, ill be affected by ater temperature, salt
levels and the input voltage of the chlorinator. When the chlorinator is operating at maximum
efficiency, the Chlorine Output level should al ays be approximately the same level as the Set
Point. The set point can be checked on the LED display hich is divided into 8 sections. If all
8 LED’s are illuminated, out set point is at 8. If only 6 light are illuminated, the set point is 6

Your SALT EXPERT Salt chlorinator ill al ays attempt to adjust the output so that the actual
output level matches set point level. At times hen the Chlorine output level is lo er than the
set point, check the salt level in your s imming pool at your local pool shop. Alternatively,
you may have a lo voltage supply to the chlorinator (less than 240Volts) or the ater may be
colder than usual.

3.6 Safety Backwash
When back ashing your sand filter, the pool ater does not pass through the cell. During the
back ash and rinse process, most chlorinators ill build up potentially explosive hydrogen gas
in the Chlorinator Cell.
The Safety Back ash function allo s the pump to turn on ithout applying po er to the
Chlorinator Cell. This prevents the build up of hydrogen gas during the back ash and rinse
process. In addition, the Safety Back ash function has set run times after hich the pump ill
automatically turn off. This ill prevent extended back ashing and potential excessive ater
loss from the pool.
To Back Wash and Rinse your filter follo these steps:
1. Press the pool mode button to the “off/standby” mode
2. Turn the Multiport Valve to “Back ash” position
3. Press the Safety back ash button on the user panel – the pump ill no start ithout
applying po er to the chlorinator cell
a. Press once for one minute pump operation
b. Press t ice for t o minute pump operation
c. Press three times for three minute pump operation
d. Press a four times to turn pump off
4. After pump turns off turn the filter multiport valve to Rinse
5. Press the Safety back ash button on the use panel once for a one minute rinse
6. When pump turns off, move the multiport valve back to filter position
7. Press the pool mode button to “Auto” function so that chlorinator ill operate on time
clock settings.
3.7 Run Dry Safety Feature
Your SALT EXPERT Chlorinator incorporates a run dry safety cut out. When the Chlorinator
turns the filter pump on, it ill check for ater flo . If no ater flo is detected ithin 3
minutes, the chlorinator ill turn the pump off. This is designed to protect the pump seal and
parts from overheating if no ater flo is present.
On initial start up, you ill need to prime the pump. In some cases, the pump ill take more
than three minutes to prime and for ater flo to be detected by the chlorinator. If this should
occur, simply start the pump again by pressing the Pool Mode button to “on”.
If during normal operation, the chlorinator s itches the pump off after three minutes, then
check the position of all valves, empty skimmer basket and pump basket and clean the filter.
Please see page 12 for the recommended method of Cell Cleaning.
