CHLORINE GENERATOR INSTALLATION
ELECTRODE HOUSING
The electrode housing may be installed either horizontally or vertically in the pool return
line. The water can ow through the housing in either direction. Plumbing may be either
a 40mm or 50mm pipe.
Horizontal - the plumbing connection on the side of the electrode
housing must face downwards.
Vertical - the plumbing connection on the end of the electrode housing
must face downwards and the electrical connections must be protected
from the weather. The electrode housing should be installed in a
weatherproof, well ventilated pool shed.
Gas trap - the electrode housing must be installed to form a gas trap as shown
below. If water was to stop owing and the chlorine generator continue running,
chlorine gas pressure will build up in the housing and pipe work and cause damage.
This can happen if water continues to run back into the electrode housing (e.g.
from an outgoing pipe after the pump is turned o), allowing water to come in
contact with the electrodes producing a build-up of gas. A gas trap allows the gas
to displace water away from the sensor terminal, thus turning o the Chlorine
generator power supply and causing the “water ow” alarm to turn on.

The power supply should be installed in a weatherproof, well ventilated area and mounted
vertically within 1.5 metres of the electrode. Although the unit has an IP24 rating it can still
be susceptible to wind driven rain.
The SMC chlorine generator can be tted to pools with any type of heating system. Do
not install chlorine generator and water heater in reverse as the heavily chlorinated water
could damage the heating unit and may negate the heater warranty.

ADDING SALT TO A NEW POOL
Calculate the pool’s water volume as follows: average length x average width x average
depth in metres. Multiply this answer by 5. The answer is the amount of salt
in kilograms you need to add to increase the salinity of your pool from fresh water to
5000 ppm (the recommended salt level for this chlorine generator).
Turn on the power to the chlorine generator and press the “Min/O” button. Continue
pressing the “Min/O” button until all of the green production lights turn o. This will
lower chlorine generator production but leave the pump running.
Add the calculated quantity of salt (rened NaCl recommended) to the shallow end of the
pool. Brush the salt to help it dissolve. Undissolved salt may stain your pool’s nish.
It is recommended to leave the pump running for 12 – 24 hours, then turn on the
chlorine generator production by pushing the “Max/On” button and increase the
output to maximum.
Your chlorine generator is designed to maintain a sanitizing chlorine level in your pool.
It will take a number of days of continuous running to reach this level. Have the water
chlorine level tested daily until it reaches 1.5 – 2.0 ppm. At this point you can adjust the
running time and production level to suit your requirements.
The most eective method of chlorinating your pool is to run the pump long enough
to pass all the pool water through the lter/chlorine generator’s cell at least once a day.
If your chlorine generator does not produce enough chlorine, increase the running time.
Chlorine demand and running time will vary and depends on a number of factors such as:
bather load, chemical balance, water temperature, sunlight exposure, type of ltration
media, etc.
Check the water chemical balance (page 15). A correct chemical balance
and chlorine level will ensure optimum pool water quality.
For example, Pool size = 60,000 ltrs; Pump ow = 200 ltrs/min.
Pool size (ltrs) / [pump ow (ltrs/min) x 60 mins] = 5 hours to lter the water once.

INTRODUCTION TO THE TIME CLOCK
The time clock is accessed by pulling down the bottom ap of the front cover. There are
four buttons: “Clock”, “Timer”, “Man” and “Auto”.
“Clock” and “Timer”: Used to enter and exit the timer settings. Once
the timing program is set they are not used again unless you wish to alter the
program times.
“Man”: Used to change settings during programming. Used also to manually
turn the chlorinator and pump on and o.
“Auto”: Used to advance to the next setting during programming. Used also
to enter the automatic time clock operation.
The time clock has a 24-hour clock face which is divided into 48 segments, each of
30 minutes duration (Fig. 1). Each of these segments can be turned ON (darkened) or
OFF (not showing) as required, allowing for very exible operation of your chlorinator
and water ltering.
Fig. 1

TM
For your convenience the time clock has two factory programs ON periods.
This program is recommended for the average pool. These are 8.00am
to 12.00 midday and 4.00pm to 8.00pm. (Fig. 2)
To have the time clock operate correctly, you will rst need to input the correct time of
day into the clock (see Entering Correct Time on page 10).
The time clock will then, after about an hour with the power applied, maintain the correct
time and settings for about 2 weeks with no power connected. This back up function
allows the clock to operate during any power outage (e.g. cheaper tari) and not lose the
programmed settings.
Now you have to decide:
1. To use the preset times and do nothing further with the time clock.
2. How long per day you want to run the chlorinator.
3. What times you want the chlorinator to run, bearing in mind the pump noise
and the eect this could have on your neighbours.
(See Programming The Timer on page 11)
Fig. 2
NB: Consult your electricity
supplier to ensure your
tari rate provides
electricity during
these times.

MAINTENANCE
ELECTRODE INSPECTION:
SMC series generators have a reverse polarity feature which reduces electrode cleaning
to the minimum. Regular inspection of the electrode is recommended.
ELECTRODE REMOVAL:
Ensure the power to the chlorine generator is switched o.
Unplug the electrode lead from
the electrode.
Step 1
Unscrew (anticlockwise) the large
threaded locking nut.
Remove the electrode from the housing.
Look inside the electrode for signs of
calcium build up (a white chalk-like
substance). If there is calcium build up the
electrode will require cleaning. If cleaning
is not required reassemble the electrode.
Cleaning and reassembly are on page 15.
Step 2
Step 3

15
TM
ELECTRODE CLEANING:
Mix up a solution of 1 part hydrochloric acid to 8 parts water. Submerse the electrode
in this solution, as shown in the picture below.
There will be a reaction as the calcium is dissolved. When the reaction ceases
(about 10 minutes) rinse the electrode in clean water, wipe the brass terminals dry and
check that all calcium has been dissolved. If not, repeat the process with a new solution.
ELECTRODE REASSEMBLY:
Ensure the silicon seal is still in place on the inside circumference of the electrode cap.
Insert the electrode back into the housing and screw on (clockwise) the locking nut.
Plug the electrode lead back on to the electrode terminals and turn on the power to
the chlorine generator.
WATER CHEMISTRY:
Have your water tested regularly. Transport
the test water in an opaque container and
have the test done as soon as possible for the
most accurate results. The following is a list of
recommended water chemistry levels.
CAUTION:
• When working with acid the
use of eye protection and
rubber gloves is strongly
recommended.
• When mixing, add acid to
water, but NEVER water
to acid.
Salt: 5000 ppm
Total alkalinity: 90 – 150 ppm
Chlorine: 1.5 – 2.0 ppm
Cyanuric acid: 40 – 65 ppm
pH: 7.2 – 7.4
