What’s In the Box?
• Hydrochlor® Power Pack • Hydrochlor® Self Cleaning Cell and Housing
• 40/50 Bushes • Cables to connect the Self Cleaning Cell
• Manual • Waterco’s Warranty Terms and Conditions.
FEATURES
The Hydrochlor® will automatically maintain the chlorine level of your pool and eliminate problems
associated with periods of very high or low chlorine levels. Fewer uctuations in chlorine levels
mean fewer uctuations in pH levels. This adds up to more stable, balanced water.
Consistently maintained sanitizer levels in the pool water will prevent the growth of all common
algae. A salt-water chlorinated pool requires much less attention than a chlorine pool.
Chlorine Generation
Through the process of electrolysis, a saline solution pass over an electrolytic cell, then the
saline solution is separated into its basic components: chlorine and sodium. The chlorine is
instantaneously transformed into Hypochlorous acid; this the chlorine form that kills algae and
other harmful organism in the water.
A chlorine generator’s main function is to produce chlorine for the pool. This keeps a residual of
chlorine in the pool that prevents algae from growing. The chlorine then turns back into salt and the
system continues as long as the generator is functioning properly.
HYDROCHLOR®
Hydrochlor® consists of a Power Pack with a built in timer
(to supply power to the cell) and Salt Cell (where the chlorine
is produced).
Hydrochlor® Power Pack
The Power Pack monitors and controls chlorine production
by regulating the amount of electrical energy supplied to
the salt cell.
Ezy Timer
Programme the chlorinator timer to turn on or
off at any time that suits your lifestyle.
The Timer controls power to the Chlorinator
controller. The timer has a liquid crystal
display (LCD) to indicate the time of day
and current operating mode.

There are 8 keys which are used for setting the Time, Timers and operating Modes. The function of
these keys is described below:
HOME Display current Time of Day or to exit Timers setting.
TIMER Toggle between START and FINISH of Timer 1 and Timer 2 for summer and then
for winter. Set times can be altered while displayed.
Timer 1 START
Timer 1 FINISH
Timer 2 START
Timer 2 FINISH
Timer 1 START (winter mode)
Timer 1 FINISH (winter mode)
Timer 2 START (winter mode)
Timer 2 FINISH (winter mode)
RESET Reset time to 0:00 and timers to the default programming.
HOUR Enable changing the hours for the current time of the day or Timer Settings.
Subsequent presses will change the hours immediately.
MIN When rst pressed this key will enable changing the minutes for the current time of
the day or Timer Settings. Subsequent presses will change the minutes immediately.
WINTER By selecting WINTER, hours of operation will be reduced to save energy during the winter
months. Deselecting WINTER will instantly return to increased hours of operation for the
non-winter months (AUTO operation).
SUPER CL Superchlorination – If the SUPER CL key is pressed once the Hydrochlor® will be
set to produce chlorine at maximum level for 24 hours non stop overriding previous
programming and the letter SC will be displayed on the LCD screen. Pressing the
SUPER CL key again when the SC is displayed on the LCD screen will disable the
super chlorination and revert to the original programming.
MODE Sequences through the modes below:
OFF All timers off

Electrolytic Salt Cell
The Hydrochlor®’s salt cell consists of a series of titanium electrodes with opposite charges.
Hydrochlor®’s clear salt cell housing allows visual inspection of the salt cell plates and enables
monitoring of chlorine production.
The cell housing is constructed using clear U.V. stabilized acrylic. Both anode and cathode of the
self-clean chlorinator are made from uniquely coated titanium plates for extra durability.
Self-Cleaning
Hydrochlor® Self Clean Salt Cell has the added ability to reverse the polarity of the voltage to
clean calcium build up off its electrodes.
The Hydrochlor®’s electrodes, the anode and cathode and hold an electrical potential difference
between them for a designated period of time. This difference is reversed after that period of time
has expired and then the anode becomes the cathode and the cathode becomes the anode.
The reversing of polarity or electrical potential difference will then start to remove any calcium
build-up, which may have been deposited onto the cathode.
This continuous reversing of polarity will keep the cell clean from calcium deposits during its
operation, providing the chemical balance and ow of the pool water thru the cell is maintained
within normal parameters.
It is recommended that you obtain regular water chemistry tests from your local pool professional
to ensure your water balance is within range.
Battery Backup
The Hydrochlor® comes with a Lithium battery incorporated to save your settings in the event of a
power failure. The battery is rated to last 5 years.
Automatic Pool Cover Link
Hydrochlor automatically reduces chlorine production to 10% when detects the pool cover is
deployed. When the pool is open again the Hydrochlor returns to the previous chlorine production
level.
A harness connector is provided to act as switch during the deployment of the pool cover. The
harness is located at the bottom of the Hydrochlor as shown in the following gure.
Automatic cover harness link

INSTALLATION
These guidelines should be followed to install the Hydrochlor®:
a. Ensure that the chlorinator cell is the last piece of
equipment installed on the ltration system – this
is so the chlorine produced will not damage other
equipments such as heaters.
b. The cell may be installed above or below water
level. If it is below water level, please ensure that
an isolation valve is installed so the unit can be
serviced without losing water from the pool.
c. The cell may be mounted on different angles so
long as a gas trap is provided.
GAS TRAP: The cell must be positioned in such a
way as to provide a gas trap. The bottom of the
cell must be above the top surface of the pipe
from the previous piece of equipment, as per the
below diagram.
Installing the Power Pack
Choose a location for the Hydrochlor® Power Pack close enough to the Cell/Housing and ltration
pump so that both may be connected/disconnected easily. The Hydrochlor® Power Pack should
not be mounted in areas where chemicals are stored (e.g. acid and chlorine). Also ensure that the
Hydrochlor® Power Pack can be connected to the mains power outlet of the pool area.
Note that this outlet must meet the current applicable local standards at the time of installation.
Installing/Connecting the Hydrochlor® Self Cleaning Cell
The Cell/Housing assembly should be plumbed into the pool return line after all other accessories
(and prior to any heating take-offs). Note any water ow direction on the Cell/Housing. The Cell will
need to be removed from the Housing periodically for cleaning – do not place it where its removal
can be difcult/obstructed.
The Cell Cable is connected to the Cell Connector under the Hydrochlor® Power Pack cover.
Ensure that the 3 connections (2 for Cell Power and 1 for Gas Sensing) are
not loose. A loose connection is likely to cause arcing which may damage
the entire system.
NOTE: Connect all plumbing to the Hydrochlor taking care that all joints are
glued or tightened securely to prevent leaking.
Allow 24 hours for glue (solvent) to set before starting the Hydrochlor.

Timer 2 FINISH 20:00
WINTER Timer 1 START 9:00
Timer 1 FINISH 11:00
Timer 2 START 17:00
Timer 2 FINISH 19:00
All time settings can be individually programmed; however altering the [SUMMER] times will
automatically change the matching WINTER time to:
START Times [SUMMER] Time + 1 hr
END Times [SUMMER] Time - 1 hr
(Unless the START time is 23:xx hours or the FINISH time is 0:xx hours, in which case the WINTER
time will be set to the same as the [summer] time).
Therefore unless a particular set of WINTER times are required, there is no need to separately enter
them.

Overnight Operation
To program the Hydrochlor® to function a period of time that involves starting before midnight and
ending after midnight, it has to be divided in two periods.
For example: If it required to start at 23:00 and nish at 07:00. Then the Electrochlor LCD setting
should be break into 2 program periods like this:
• Program Timer 1 set to Start at 23:00 and Finish at 23:59
• Program Timer 2 set to start at 0:00 and Finish at 7:00
Note: To Reset the Timer, and Timers setting to factory defaults, press Reset Key until the time
displayed is 0:00.
CHLORINE PRODUCTION LEVELS
The output of the chlorinator can be adjusted to reect the different seasonal requirements in order
to maintain satisfactory chlorine sanitizer levels.
The amount of chlorine produced can be adjusted by pressing the CHLORINE PRODUCTION
CONTROL key. Press button to raise production. If production already set at maximum it will turn
to zero and each press will raise production by one LED till MAX.
If the pool water is over chlorinated, simply reduce the chlorine production set level.
CHLORINATOR OVERRIDE SWITCH
Normal operation is (O). To start override switch to (–) to initiate override function of stopping pump
for backwashing, vacuuming the pool to waste and lowering the pool water level. Press Mode
button to toggle between ON & OFF to control the operation of the pump. When Switch is set to
(O) the timer will return to normal operation. Once the Hydrochlor®’s override is initiated, the Timers
simply turn the pump on and off.
Caution: When the chlorinator override switch is activated the pump protection is disabled. Do not
leave the pump unattended during. Pump may run dry and may void the warranty.
WATER CHEMISTRY
Salt Level
The Hydrochlor® chlorinators must operate between the salt level ranges listed below.
• MINIMUM = 4000 ppm • OPTIMUM = 5500 ppm • MAXIMUM = 6000 ppm
Testing kits are available from the local pool professional and should be used to accurately check
the salt levels in the pool water.

I pg 07
Waterco Hydrochlor®
Note: When the LED lights ash it is an indication of:
• Low salt level
• Low temperature or
• Cell plates wearing
If you don’t know what your salt level is or how to test it, consult your local pool care specialist.
Water Chemistry
It is important to maintain the correct water chemical balance in the swimming pool; this will help
protect the Electrochlor chlorinator unit and its cell.
Consult the local pool professional for the correct water balance according to the swimming pool
type.
The Electrochlor chlorinator will run correctly at the following chemistry levels
Range Suggested
pH. 7.2 – 7.8 7.2 – 7.6
Total alkalinity 60 – 200ppm 80 – 150ppm
Calcium hardness 100 – 500ppm 60 – 250ppm
Stabilizer (Sun screen) 30 – 60ppm
SALT CELL CLEANING PROCEDURE
a. Press the MODE key until OFF on the power pack, then turn the pump and
Hydrochlor to standby mode.
b. Unscrew the barrel unions from the salt cell and disconnect the cables
from the salt cell’s brass connectors.
c. Turn the salt cell housing upside down with both ports facing upwards.
d. Pour the Cell Wash cleaning solution into the housing to dissolve the calcium build-up from the
salt cell plates. There should be just enough solution to cover the salt cell plates.
e. Allow enough time for the solution to dissolve the calcium build-up from the salt cell plates.
Approximately 5 to 10 minutes.
f. Once the calcium build-up has been removed, pour out the Cell Wash solution into a bucket and
lightly rinse-off excess calcium and Cell Wash solution from the salt cell assembly, with fresh
water.
g. Reconnect the salt cell onto the lter system
h. Press the MODE button to AUTO or ON on the power pack to reactivate the Hydrochlor.
Never use products that are not specifically manufactured to clean the Hydrochlor®’s salt
cell. Do not use raw acids such as Hydrochloric acid. This will damage the salt cell and
severely shortens its life and will void warranty. Please consult your local pool professional
for advice on salt cell cleaning products.
