Aligator Control Unit

Type ali-2

INTRODUCTION

PRINCIPLES OF OPERATION

The unit is managed, timed and controlled by a single chip microprocessor. Permanent

storage is provided by an industry standard Electrically Erasable Programmable Memory.

User control is provided by three simple push buttons, one for display mode change and the

other two for ON/OFF or UP/DOWN as appropriate. The display is a 20 character by 2 row

LCD display with backlight for operation in any location.

Power and electrode connections

The unit is designed to be connected to a permanent power supply 220/240 volts, via the

mains plug. The mains supply should not be timed or interrupted. The unit should be

mounted on the wall within 2 metres of the filter and pump.

The unit is designed to come on twice in a twenty four hour cycle for a time dependant on the

size of your pool. The user must thus set his pump operating time to suit the times in the table

shown under Pool Size Setting display below. Failure to do this will reduce the electrode

operating times and reduce the efficiency of the unit.

The control unit is connected to the electrodes via the grey four core cable. This cable has

four plugs. Two for the electrodes and two for the flow switch, both of which are situated in

the electrode chamber. Identification is simple as both pairs of plugs are distinctly different.

Polarity of either the electrodes or the flow switch is unimportant so the plugs can be fitted

either way.

The unit will operate as soon as power has been established to it and the Pool Size entered

into its computer. However, power to the electrodes will only operate when pump is on.

Electrode timing always starts when the pump starts unless the pump has been off for less

than 30 minutes e.g. for filter cleaning (or automatically after 12 hours if the pump is

continuous).

LCD DISPLAYS

On power-up the unit will display “Welcome to Aligator” for 10 seconds during which time

the electrodes will be off and the electrode current detection circuit will automatically zero

itself.

The first normal screen shown below is then displayed. Changing to other display modes is

achieved by pressing the MODE switch, each time the switch is pressed the screen advances

one display. This allows cycling right round all the screen operations. If the switch is not used

for more than 10 seconds then the unit reverts automatically to the default display (screen one)

electrode current display mode.

Aligator Owners Operator Manual

Electrode Current & Alarm

The first normal and default display is as follows:

Current: 82mA OK

Current Alarm: ON

Actual current into the electrodes will be displayed, dependant upon your pool setting.

Should the “OK” be replaced by “LOW” or “HIGH” the alarm will be activated, the red LED

will flash and the unit will “beep” this indicates that either the pool water balance or the

electrodes need attention.

The alarm can be switched off by pushing the bottom right hand button or back on by pushing

the top right hand button.

NOTE: Current Alarm reverts to ON at end of 12 hours

Pool Size Setting

The second display shows what pool size has been selected from the table below, i.e. the size

of your pool, for example:-

POOL Ltrs 9-27000

SIZE Gals 2-6000

The Top right hand button increases Pool Size from size 1 to 6.

The Bottom right hand button decreases Pool Size from size 6 to 1

Aligator Owners Operator Manual

PART TWO

ELECTRODE CHAMBER

The chamber must be fitted between the pump and the filter. The flow switch is

activated by the flow of water pushing it upwards; this indicates to the control unit that

the pump is operating. Once the flow ceases the flow switch falls by gravity back

between the electrodes. It is therefore of utmost importance that the chamber is fitted to

allow this action to take place.

Access to the chamber is by unscrewing the top flange and gradually easing out the top

transparent lid with a screw driver. A rubber “O” ring situated around the base of the lid

creates the seal. Once the lid is removed the electrodes can be replaced by releasing the 10mm

stainless steel bolts securing them through the lid. Make sure on replacing the electrodes, the

rubber seal is placed against the lid underface followed by the stainless steel threaded nut then

the electrode. Electrodes can be cleaned by simply removing the lid and wiping the electrodes

with a cloth. On replacing the lid, make sure the location lugs are in line before pushing the

lid into the chamber.

Electrodes

Electrodes are a composition of a number of metals. Under good pool management i.e.

keeping the balance of the water within range, the electrodes will last up to 12 months. The

correct wear pattern should be progressive reduction in the diameter until the electrode is

slightly more than the width of a pencil. At this point they should be replaced.

Replace the electrodes only with genuine Aligator Electrode Kits.

If other types are used the result will be a reduction in sanitation and possible staining of the

pool walls.

PART THREE

Water Preparation

Test Pool Water and bring to ideal levels:

*pH 7.0 to

7.4

*Alkalinity 90 to

150

*Chlorine 1.2 to

1.5ppm (start up)

*Chlorine 0.6 to

1.0ppm (Normal Operation)

*Cyanuric 40 to

60ppm (No Higher than 80ppm)

Please Note: IMPORTANT

Please Refer to Page 10 of this Handbook

DO NOT POUR CHLORINE GRANULES INTO THE SKIMMER IF YOUR POOL

IS FITTED WITH AN AUTOMATIC CHLORINATOR.

PLEASE REFER TO YOUR AGENT OR TO ALIGATOR FOR FURTHER

ASSISTANCE.

STABILISED CHLORINE MUST NOT UNDER ANY CIRCUMSTANCES BE

MIXED WITH UNSTABILISED CHLORINE.

Cyanuric

Is a stabilising compound used to stabilise chlorine against dissipation by sunlight. If the level

is above 80ppm it must be reduced by dumping water and adding fresh until you have

acquired the correct level. It is advisable not to use stabilised chlorine in indoor pools.

Chemical Tables for stabilising your pool water

WARNING: Do not mix chemicals together. Mixing chemicals causes Fire, Explosion

and Toxic fumes.

Aligator Owners Operator Manual

The chemical quantities are approximate. Use them as a guide until you have established the

correct amount for your pool.

To establish the size of your pool

Apply the following calculation. This will give you a reasonably accurate indication.

Measure in Meters/

Length x Width x Depth x 1000 = Volume in litres i.e. 10m x 5m x 1.5m x 1000 = 75000 ltrs

To convert to gallons multiply by 0.22. I.e. 750000 x 0.22 = 16500 Gals

pH CORRECTION

Correct Reading 7.0 to 7.4

High Reading Use Dry Acid (Sodium Bisulphate) to reduce pH Reading

Application Method:

Mix small amounts in a bucket of water and pour around the deep end of pool with the pump

set on filter. Do not mix more than 1kg at a time in an average size bucket. Care is needed as

the acid id very corrosive and any spillage should be diluted with water without delay.

Use Bi-Carb of Soda to Increase

Application Method:

Set pump multiport on RECIRCULATE ONLY, pour slowly and directly into the

leaftrap/skimmer. Leave pump on RECIRCULATE ONLY until all traces of the chemical

have entered the pool.

DO NOT ATTEMPT TO PUT BI-CARB INTO THE SKIMMER WITH THE PUMP

ON FILTER.

When correcting the stabilisation of the pool using the above chemicals, test after 24

hours and readjust as necessary.

Aligator Owners Operator Manual

IMPORTANT: When adding large amounts of acid to decrease the Alkalinity, the pH

will be reduced to a very low level. The pH will slowly increase over the next ten days as

the Alkalinity is reducing. This is normal and will not harm your pool, it is however not

recommended to swim in water below 6.5.

Flocculants and Algaecides

Neither of these substances are needed with Aligator. Aligator will kill all known algae and

through its own unique magnetic field, remove most unwanted solids from the water. With

stubborn algae ALI-CIDE may be used.

Vacuuming and Backwashing

During the first two weeks, frequent vacuuming and backwashing must be done to clear away

the residue of solids being solidified by the action of the Aligator. This action makes the

water crystal clear. After a period, depending on how contaminated the water was before the

Aligator was fitted, the vacuuming and backwashing may be resumed at the normal

frequency. Visual inspection of the bottom of the pool showing no solids present indicates

this situation. A frequent vacuuming and backwashing policy however, is absolutely essential

for the good management of your pool.

Chlorine and Cyanuric/Cyanurates

There are Four (4) main donors of Chlorine.

Two are hypo-chlorites, Liquid and Granular, commonly called Chlorine.

Two are known as Stabilised Chlorine, (Granular or Tablet) these are Cyanuric and

Cyanurate.

Their Chemical names are very long so our description will suffice for this booklet.

Stabilised Chlorine is used to minimise the loss of Chlorine in sunlight and therefore is to b

recommended in outdoor pools.

Chlorine (Non Stabilised) is used in indoor pools with artificial lighting.

Stabilised Chlorine in tablet form. We recommend the slow dissolving (200g) tablet

(dissolves in 5 to 7 days) in outdoor pools and also indoor pools where sunlight penetrates the

water.

IMPORTANT: Whenever Stabilised chlorine is used, the Cyanuric Acid level must be

monitored and kept below 80ppm.

(See paragraph headed Cyanuric/Stabilised Chlorine for more information).

DO NOT MIX STABILISED CHLORINE WITH NON STABILISED

CHLORINE EXPLOSION MAY RESULT.
