GENERAL PRECAUTIONS
•Do not use bromine based products in the pool. Use of bromine will void the
warranty on your chlorine cell.
•It is the pool owner's responsibility to ensure water is regularly tested and balanced.
Your local pool professional can advise you on appropriate testing frequency and
balance criteria in your area.
•Where calcium hardness of the pool / spa water exceeds 200ppm, the water must
be balanced as per the Langlier Index to ensure water is not scale forming. Consult
you local pool professional for advise.
•Do not assume the chlorinator is faulty if a chlorine test reveals a low free chlorine
level. There are many factors that relate to chlorine demand in the water. Refer to
the troubleshooting guide in this manual for more information
•Regular manual 'super chlorination' or 'shock dosing' may be required in pools
where chlorine demand or bather load is high.
•anual addition of liquid chlorine may be required to supplement chlorine
requirement during peak usage periods.
•Test salt level before calculating your salt addition requirements, even on a new
installation – especially where liquid chlorine had been used previously.
•Free chlorine levels above 4.0ppm may void manufacturer warranties on your
equipment.
•Unnecessarily high salt levels may contribute to corrosion of pool and spa
equipment.
•Pool Lab r comm nd th us of Cyanuric Acid (Stabiliz r) at a conc ntration
of b tw n 50-80 ppm for outdoor pools to h lp prot ct chlorin in th wat r
from d struction by sun light
ELECTROLYTIC CELL PRECAUTIONS
•It is a condition of th warranty that th pool own r nsur that th c ll is
insp ct d and maintain d in accordanc with th dir ctions in this manual.
•The chlorine cell is generally self cleaning, but certain water conditions can inhibit
the effectiveness of this function. Therefore the cell should be visually inspected on
a regular basis to ensure it is not fouled with debris or accumulating calcium. Refer
to instructions on cleaning the cell in this manual if required.
•If calcium scale is allowed to build up on the electrode plates to the point where the
calcium bridges the gap between the plates, this can permanently damage the
electrode and will void the electrode warranty.
•If you have water conditions that cause calcium to build up in the chlorine cell, then
the cell UST be cleaned on a regular basis as per the instructions in this manual.
As a general rule, if the cell requires more than 15 minutes to clean, then it must be
cleaned more regularly.
•It is th pool own r's r sponsibility to nsur all mat rials in contact with th
pool or spa wat r ar compatibl with and int nd d for us with an

INTRODUCTION
Congratulations, you have wisely purchased the most technologically advanced salt water
chlorinator in the world. The benefits of doing so will be evident for many years to come.
Pool Lab’s research and development team is committed to producing the finest
chlorination systems and being recognized world wide as the leaders in salt chlorination
technology.
Your Pool Lab chlorinator will eliminate the need to store dangerous quantities of chlorine,
daily manual chlorine dosing and the risks associated with these practices. It is automatic,
clean, safe and economical and for these reasons, salt chlorination as a method for
treating pool water is increasing world-wide.
ild salt water is gentle on eyes and skin and is said to benefit asthma sufferers and those
people who find conventional chlorinated pools irritating. The salinity of seawater is
approx. 35,000ppm or 3.5%, while Pool Lab chlorinators require only 3,000ppm or 0.3%.
The human body has a salinity of approx. 4500ppm and fresh water is zero. It is the
similarity between the salinity of the human body and that of a salt pool that make for a
silky luxurious swimming experience.
The chlorinator comprises two basic components, the power supply and cell. It is within the
cell that the electrolytic reactions occur. Chloride ions in the water are converted into
chlorine gas, this dissolves immediately into the water to ultimately form sodium
hypochlorite (liquid chlorine). The chlorine oxidizes bacteria, algae and other harmful
matter in the pool water and through this process reverts back into available chloride ions.
The major by-product of the reaction in the cell is the liberation of Hydrogen gas at the
cathode. This explains the small bubbles often seen passing out of the pool returns. Pool
Lab’s patented vertical cell is the worlds safest and ensures the excess hydrogen gas can
not accumulate to dangerous levels.
No salt is lost through the electrolytic process. The necessity to top up the salt level is only
due to loss of salt water from backwashing or splashing out etc. Water loss due to
evaporation does not cause any loss of salt. All Pool Lab models contain digital time
clocks with two programmable ON/OFF periods available for fully automatic operation of
your pump & chlorinator.
All mod ls hav a built in back up pow r syst m that will k p th tim r clock
running for up to 7 days. This is particularly us ful wh r th mains pow r is
int rrupt d.
Pool Lab PL S ri s do s not contain batt ri s.

CELL MAINTENANCE
Where calcium levels are below 200ppm, the mineral content is low and the water is
correctly balanced, little or no maintenance to the cell is normally required. The automatic
reversing of the electrode polarity will be sufficient to dissolve the calcium scale formed.
Periodic inspections must however be made to ensure scale and or debris is not forming
or building up on the electrodes within the cell. If a calcium scale has formed it must be
removed by cleaning in an acid solution.
Where calcium levels are higher than 200ppm and or mineral content is high, regular
inspections of the cell must be performed. If calcium scale is present, the cell must be
cleaned in an acid solution. The higher the water temperature, the greater the capacity for
the water to deposit scale on the cell. Each pool will vary with regard to the frequency of
cell maintenance. Factors which increase the cell cleaning frequency are:
•Calcium Hardness above 200ppm
•High Water Temperatures
•Low water velocity
•Poor Water Balance
•Excessive salt level
•Electrode breakdown – ensure a qualified technician evaluates the cell
TO REMOVE & INSPECT THE ELECTRO E
•Switch off power to the chlorinator and pump(s).
•Close all relevant valves – especially where the cell is located lower than the pool
water level, or where the pump(s) are significantly above the water level.
•Unplug the cell cable from the cell, and place cable end in a dry location.
•Loosen the large cell nut, and remove it from the cell.
•Carefully remove the electrode from the cell housing. Where the cell is located
above the pool water level, and the cell is not completely isolated by valves, beware
that there may be a vacuum in the cell housing. This can sometimes make the
electrode difficult to remove. Take care not to lose the o-ring.
Depending on your system setup, the vacuum can sometimes be relieved by briefly
pushing down on the multi-port valve handle on a sand filter, or by opening a relief
or drain valve momentarily.
•Visually inspect for debris accumulated at the bottom of, or between the electrode
plates. ost debris can usually be cleared by simply dunking the electrode up and
down rapidly in water. Excessive debris could indicate a filtration problem.
* DO NOT USE A METAL TOOL TO REMOVE DEBRIS AS THIS WILL DAMAGE
THE ELECTRODE COATING!!
* DO NOT ATTEMPT TO MANUALLY REMOVE ANY CALCIUM SCALE
•Visually inspect between the electrode plates for calcium build up. This appears as
a hard white material that coats the surface of the plates and can also bridge the
gap between the plates. Electrode plates should be smooth and matte black.
7
CLEANING THE ELECTRO E – CALCIUM SCALE
You will need hydrochloric acid (33%), and a plastic container or bucket deep enough to
stand the electrode vertically in with the electrode plates fully submerged. The container
or bucket should be preferably not too broad, as this will require a larger amount of acid.
A standard 10 Litre bucket is usually acceptable.
You will also need safety goggles and protective gloves.
•Remove any loose debris from the electrode by dunking it up and down rapidly in
water.
•In your container or bucket mix approximately 1 part hydrochloric acid to 5 parts
water. ake the solution slightly too shallow at first, then top up later with water to
just cover the electrode plates.
Note Less acid can be used (down to 1 10 ratio) if the calcium build up is not too
excessive, but the cleaning process will take longer.
ALWAYS PUT WATER IN THE CONTAINER FIRST, THEN ADD ACID.
•Carefully place and stand the electrode in the container, taking car NOT to
subm rg th top part where the electrical connector is. Top up the container with
fresh water if required until the electrode plates are just covered by the solution.
Note ACID REACTING WITH THE CALCIUM SHOULD PRODUCE BUBBLES
•Leave the electrode in the solution until the bubbles stop. The reaction will usually
be fast initially, then slow down.
•Once you are satisfied the reaction has stopped, carefully remove the electrode
from the solution, and rinse with fresh water.
Note If calcium scale was excessive you may need to repeat this process with a
fresh acid solution.
•Visually inspect the cell to ensure you are satisfied it is clean. If some scale-like
build up remains and it appears that acid is not removing it, then it may not be
calcium scale. You can try rinsing the cell with hot tap water (not boiling water)
which can sometimes help.
INSTALLING THE ELECTRO E
•Visually inspect the condition of the o-ring, and replace if necessary.
•Apply a small amount of silicone grease to the o-ring if required.
•Fit the o-ring to the cell head, ensuring it is on the bottom side of the cell head
flange (same side as the electrode plate bundle).
•Fit the electrode into the cell housing, and orient it so that the cell cable can plug
into the cell easily and comfortably.
•Fit the cell nut, and tighten by hand only.
•Connect the cell cable to the cell.
•Open any valves that were closed prior to the electrode being removed.
•Re-connect power to the chlorinator and pump(s).
•Run the system – and check for any leaks.
