THE WATERMAID WM10 FRONT CONTROL PANEL
The WATERMAID WM10 Power Pack has a control panel that consists of an LED, chlorine production
readout indicating the percentage (%) of chlorine production being produced by the WATERMAID cell.
The Chlorine Production rate of the WATERMAID Unit can be set at a desired level by using the
- or + buttons on the front Control Panel.
The % figures shown on the front of the Watermaid WM10 Power Pack correspond to the following
chlorine production values below.

There are Six influencing factors that determine the chlorine output that is produced by the cell.
1. THE CONTROL PANEL SETTING -- This is the level that is set by the user by depressing the
- or + buttons. The actual reading that is obtained will also be influenced by the five other factors
listed below.
2. THE REQUIRED LEVEL SETTING WILL DEPEND – upon the size of the pool, how many
people are using the pool, how well the pH is controlled and filtration running cycle.
3. SALT LEVEL -- The salt level in the water, determines how conductive the water is and how
much current (Amps) the cell is able to draw from the Power Pack, proportional to the LED
readout on the front panel of the WATERMAID Power Pack.
A recommended Salt Level of 5000 PPM (parts per million) will result in a EZ300 Cell or QT300
Cell drawing approximately 30Amps or 100% reading on the indicator LED's.
A salt level below this range will result in the LED readout to drop to below 100% and therefore
less chlorine being produced.

If the salt level drops to a very low level, ALL the -GREEN LED indicators- on the readout will
not illuminate until eventually only the first three AMBER lights will illuminate. (Indicating to
check the salt level) The illumination of AMBER lights also indicates that low levels of chlorine
are being produced and that more salt may need to be added to increase the salt level in the pool
so that the WATERMAID Chlorinator can produce more chlorine, enough so that the pool
remains clean, clear, sparkling and sterile.
PLEASE NOTE:
The WATERMAID QT400 Cell only requires a salt level of 4000 PPM to achieve a reading of
100% on the front control panel. This is ideal for pool owners that wish to run with a lower salt
level. An even lower level may only be needed for pools that are heated.
The figures given in the table above, assume a water temperature in the pool of 20 Deg. C / 68
Deg. F.
4. WATER TEMPERATURE -- Water temperature is also a determining factor in the amount of
chlorine production that the cell produces, again proportional to the LED readout on the front
panel of the WATERMAID Power Pack.
WARMER WATER TEMPERATURES result in the water being more conductive and the cell
producing more chlorine.
COOLER WATER TEMPERATURES result in the water being less conductive and the cell
producing less chlorine.
PLEASE NOTE:
Swimming Pool & Spa Owners that use HEATERS to warm the water can maintain a lower salt
level in the swimming pool and still achieve a 100% reading on the LED Control panel.
5. CALCIFICATION ON THE CELL -- The build-up of calcium deposits on the centre cell
electrode can also determine the chlorine production from the cell.
THICK heavy build-up can result in less chlorine being produced.
VERY HARD, THIN calcium deposits can also reduce the chlorine production from the cell.
PLEASENOTE:
Usually a small build up of calcium will not result in a loss of chlorine production from the unit.
Is advised to inspect the cell every 2 - 4 weeks and check the build up on the cell.
If necessary, clean the cell as per the instructions.
In some cases, a thick calcium build-up may cause the reading on the LED % readout to read
normally however result in low levels of chlorine being produced by the cell. It is important that
an inspection of the cell is done on a regular basis.
6. CELL AGE - Normally a WATERMAID cell will have a minimum life of 5 or more years.
Cells beyond this age may deteriorate and result in less chlorine being produced from the cell.
This is also indicated by the LED readout dropping below 100% and therefore less chlorine being
produced.
When salt levels are maintained within the correct range but the LED readout is low, the cell is
clean and the cell is beyond 5 years of age, a NEW cell may be needed to produce sufficient
amounts of chlorine for the pool.

The RED LED indicator light has TWO states of operation.
1. If the RED LED Indicator is flashing it will indicate that there is a flow fault or problem with the
cell. The Cell should be inspected to see if there is water flowing freely over the electrodes and
there Is no gas (air or hydrogen) inside the cell
2. If the RED LED Indicator is STEADY RED (not flashing) it will indicate that the power pack is
in an overload state and that it has shut itself down to protect itself from any damage.
The cell should also be inspected to see if there are any calcium deposits on the Gas Sensing Tang of
the cell.
The cell connections.
The WATERMAID Cell connections to the Power Pack should also be inspected to ensure they
are tight and free of electrical corrosion or damage.
The MOST LIKELY cause will be that the SALT LEVEL in the pool is in excess of what the unit
requires to operate efficiently. It may also be that SALT has recently been added to the pool and
un-dissolved salt is passing over the electrodes. When adding salt to the pool, always ensure the
WATERMAID unit has been shut off or the chlorine production turned down to the lowest
setting. (By using the - button)
The solution for a Power Pack that is in an overload state is to dilute the water in the pool by
emptying the pool approximately 15cm / 6 Inches at a time and refilling with a fresh water source.
This may need to be repeated several times until the unit is operating correctly again and all lights
are indicating between the 75%- 100% range.
It may also be a good opportunity, if you have a sand filter to give the filter a thorough backwash
whilst solving this temporary problem.
THE BLUE, AUTO CELL CLEAN indicator lamp will illuminate when the Power Pack is operating
the inbuilt cell cleaning features.
It is designed to come on at regular intervals during a chlorination cycle and will operate for
approximately 5 – 10 minutes each time.
No Green Light - No Amp Reading - No Chlorine Output
During the normal process of producing chlorine in the electrolytic cell,
Calcium deposits will develop on the cathode electrode of the cell. This
needs to be removed to ensure proper operation and chlorine production
from the Watermaid unit.
Apart from cleaning the cell electrodes, it may also be necessary to clean
the Gas Sensing Tang inside the Watermaid Cell.
It can develop calcium deposits that need to be removed. It is not
common, but in some cases can result in preventing the Watermaid unit
from functioning and producing chlorine.
Also ensure the Brass Plug is CLEAN AND A TIGHT FIT – this can be
adjusted by gently prising the two sections of the plug apart clean and
smear with ‘Vaseline’ or ‘Silicone Grease’ to prevent atmospheric corrosion.

Watermaid Maintenance - Simple Guide
With all equipment it is necessary to carry out periodic checks to ensure correct and reliable operation.
In all cases the Watermaid manual should be read and understood to ensure
reliability and compliance with warranty requirements
The Watermaid system should be checked periodically especially when the swimming pool temperature
starts to rise following the winter period.
The main things to check are the power supply lights are indicating correctly and that the cell is clean
with minimal calcium build-up.
This is most noticeable in hard water areas and sometimes a clean is required depending on how much
calcium is produced.
BEFORE REMOVING ANY PART – ENSURE THE SYSTEM IS SWITCHED OFF AND THE
VALVES ARE CLOSED – INCLUDING THE MULTIPORT VALVE
Cell removal:
1. The Cell is connected via a low voltage grey power cable to the terminal box of the power pack.
2. The cell wires must be connected polarity correct for the cell to work.
3. The brown lead is connected to the brown or red (positive lead) in the terminal box.
4. The blue lead is connected to the blue or black (negative lead) in the terminal box.
5. The white or centre gas sensing wire on the cell is connected to the centre terminal in the terminal box
Make sure the Terminals are kept tight and dry for efficient operation.
2. CLEANING THE EZYCLEAN CELL:
1. Unplug the Brass Connector at the Top of the Cell Head.
2. Unscrew the Top Barrel Nut from the Top of the cell.
3. Gentle Twist the Cell Head and Pull the centre electrode out from the Casing.
4. Simply Scrape the Electrode clean with a Plastic of metal device or use a piece of 32mm PVC
Plastic pipe and run this up the Electrode to remove all deposits.
5. If the Cell is heavily encrusted with Calcium Deposits and both Electrodes are built up. Replace the
Centre Electrode after cleaning and unscrew the bottom barrel nut and remove the entire Cell from the
pipe work.

ONLY IF THE CALCIUM DEPOSIT CANNOT BE REMOVED
WITH FINGERS etc.
With the cell assembled and completely removed from the pipe work, place the cell upside down into a
bucket and follow the directions below for cleaning the cell with a DILUTE solution of acid.
IN A PLASTIC OR GLASS CONTAINER, dilute one part Hydrochloric (muriatic) (Pool) Acid with
ten parts of tap water (Hot Tap Water is more efficient)
WHEN MIXING, ADD ACID TO WATER, NOT WATER TO ACID
and
DO NOT MIX ACID AND WATER IN THE CELL
Do not immerse the cell electrodes in a strong acid solution, as it may shorten the cell life and damage the
electrodes.
Pour the dilute acid mixture into the cell.
When the effervescing stops inspect the cell and if still calcified repeat the process.
Rinse cell with water and insert into the pipe work when finished.
FOR SOFT DEPOSITS - Try rubbing the deposit off with your fingers or Hosing out the Cell with a
strong jet of Water. This will usually clean the cell sufficiently and cell cleaning with acid may be
avoided.
To keep the Cell deposits SOFT add 3 - 10 Kg of Magnesium Sulphate (Epsom Salts) to the pool water
every 6 Months.
Or if the Calcium is hard and frequent:
Add 25 kg of Magnesium Sulphate (Epsom salts) to the water every 12 months.
This will soften any deposits that form making them soft and slushy. It will also make the cell far easier
to clean (usually just with a rag)
Also try putting a cake of PURE soap (no additives) in the Skimmer box. You will notice the calcium
deposits become soft and slushy.
On Completion and before switching the pool system back on return all
valves back to their original positions
You may now switch the system back on checking for any leaks before leaving the system to run
automatically.
Remember in the warmer weather the system will need to operate much longer than in the winter
time – Depending on pool size and bather volume.
Remember the pool system should always be running when the pool is being used, normal filtration
times are simply to maintain the water ready for use
Always ensure your pool water is in balance, ph should be between 7.2 & 7.6 For Example a higher pH
will make the Chlorine less effective. pH 8.6 = Chlorine only 10% - pH 7.2 = 70% effective
An Auto-pH system makes the most economical use of pH minus and maintains the pool
far better than possible doing it ourselves
Use chlorine stabiliser especially during the hot weather – if you cannot easily obtain this contact
WATERMAID EUROPE S.L. we normally have this in stock – you should have approximately 50ppm.
With all methods of maintaining swimming pools it is recommended to ‘Shock’ the pool every month,
especially during hot weather.
Run the pool system for 24 hours with the Watermaid at 100%.
Algae breed during daylight particularly when it is hot and sunny – to kill algae and help prevent
occurrence of algae – Pool systems should be run mostly after the sun has gone down, this will kill the
algae and prevent them from breeding the next day.
Always operate your pool system when the pool is being used as this is when most contamination occurs.
