1.0 FOREWORD
1.1 Congratulations on purchasing a Reltech EvoChlor Saltwater Chlorinator for your swimming
pool. This system is designed for robust reliability and easy operation to provide many years
of trouble-free service. Please read the instructions thoroughly before operating the unit. If you
have any concerns or require further assistance, please do not hesitate to contact our friendly
sta󰀨 or any of our Reltech distributors.
2.0 POOL CHEMISTRY
2.1 It is important to note that the EvoChlor Chlorinator does not maintain the water chemistry of
the swimming pool water; it simply produces chlorine from a mild salt solution. To ensure that
the water is chemically balanced within the guidelines listed below, the pool water should be
tested regularly at a pool shop to maintain a sparkling and healthy pool.
pH 7.2 – 7.6
Total Alkalinity 90 – 150ppm
Cyanuric Acid 40 – 65ppm
Salt 4,000ppm
Chlorine 1.5 – 2.0ppm
2.2 The EvoChlor Chlorinator is designed to operate on a salt level of 4,000 parts per million
(ppm). This is easily achieved by using the formula below, or approximately 20kg of salt for
every 5,000 litres.
For example:
Pool volume = Length x Width x Average Depth x 1000
= 9m x 4m x 1.5m x 1000
= 54000 litres
Salt required = Pool Volume x 4 (salt level required, 4000ppm)
1000
= 54000 x 4
1000
= 216kg
Or 11 x 20kg bags of pool salt
2.3 NB: Before adding salt to the swimming pool, please ensure the EvoChlor Chlorinator
is switched o󰀨 to avoid overload damage. FAILURE TO DO SO MAY VOID WARRANTY.
2.4 It is recommended to manually add chlorine to the swimming pool on initial startup as a
saltwater chlorinator is designed to maintain chlorine levels and not run for unnecessary long
hours to try to build an acceptable chlorine level. The manual addition of chlorine may also be
required for unforeseen situations where the swimming pool has a high chlorine demand, for
example, after a large bather load.

3.0 CELL INSTALLATION
3.1 The electrolytic cell housing must be plumbed into the return line after the lter. Please
refer to the installation diagram, Fig.1, below for the preferred method. The cell housing has
allocations for either 40mm PVC pipe or 50mm PVC pipe with the use of the supplied PVC
reducing bushes.
3.2 If a heater is plumbed into the system, then the cell housing must be installed after the heater
in the return line to protect the elements or heat exchanger. If a solar heating system is tted,
then the cell housing should be installed after the return line coming back from the roof if it
rejoins the main swimming pool return line.

4.0 POWER PACK INSTALLATION
4.1 The EvoChlor Chlorinator power pack is wall mounted by either using the supplied mounting
bracket or directly hanging on the wall with screws (300mm centres). The power pack is to be
mounted at least 1 metre above the ground and 3 metres or more from the pool edge.
4.2 It is strongly recommended that the power pack be installed where it is protected from the
elements. Rain and sunlight will prematurely age the unit. It should also be mounted in a
position where it is away from accidental water spray. The power pack should be installed
so that adequate airow can circulate freely around the unit to allow for su󰀩cient ventilation.
4.3 The power pack comes with a standard 230V 10A power cable that is to be connected to
mains power. Plug the power cable into a suitable weatherproof outlet.
4.4 The power pack is tted with a 230V 10A power socket located on the right-hand underside
of the power pack. The pool pump should be plugged into this socket so that the chlorinator
and pump activate together when the timer switches on at the allocated time settings. In a
model without a timer, the pump and chlorinator are controlled by the on/o󰀨 switch (7 in Fig.
3). Failure to plug the pool pump into this socket could lead to the chlorinator staying on with
no water circulation. Without circulation, and in the event of a water probe failure, overheating
and a possible gas build-up may occur. This build-up may damage the cell housing.
4.5 Some automation systems may require the pump to be plugged into mains power. Please
consult the manufacturer on the specics of this.
4.6 The electrolytic cell cable is connected to the power pack at the junction box on the underside
of the unit. With power o󰀨, remove the protective cover from the junction box and insert the
cell cable wires to the terminals, with the thin wire connecting to the middle position. The
screws must be rmly tightened, so there is solid contact between the wires and the terminals.
Replace the protective cover back over the junction box.

5.0 OPERATION
5.1 The control interface on the power pack consists of the following.
1. Chlorine Output LEDs
If the correct salinity level is maintained in the water, then all ten lights will illuminate at full
output (100%). Each light represents 10% chlorine output. If all lights are not illuminated, then
a higher salinity level will be required. Make sure all salt is dissolved correctly before adding
more. The chlorine control (2 in Fig. 3) will increase or decrease the chlorine output to suit the
chlorine requirements. If all of the indicator lights ash, then there is a water ow fault.
2. Chlorine Control
The chlorine controller determines the amount of chlorine production. By simply turning the
control clockwise, chlorine output is increased, and by turning the control anti-clockwise,
chlorine output is decreased. Do not force the control past its stop as this will damage the unit
and void warranty.
3. High Salt Light
This light is a red warning indicator and will illuminate when the salt level in the swimming
pool is higher than 4500ppm. If this light is on, together with the ten output LED’s (1 in Fig.
3), decrease the output by turning the chlorine control (2 in Fig. 3) anticlockwise until the high
salt (red light) goes o󰀨, and all ten chlorine output LEDs remain on. If this light is the only one
illuminated then the unit has gone into the over-temperature cutout and will reset once back
to normal running temperature.
4. Polarity Light
The polarity light is the rst indicator light, 10% in the chlorine output array (1 in Fig.3). This
light will alternate between orange and green every reversing cycle, 4-12 hours. The factory
setting is a 12-hour cycle.

5. Timer
The FM/1 series time switch is a 24-hour timer for controlling the chlorinator and associated
circulation pump.
Setting the Timer
To set the time, turn the minute hand clockwise until the time of day on the outer dial is aligned
with the arrow on the inner dial. For example, to set the chlorinator and pool pump for 8.00pm,
adjust the timer as per Fig. 4. The inner dial on the timer has 24 hr markings with 15-minute
increments. Turn the minute hand clockwise until 20, or 8.00pm, is aligned with the arrow on
the inner dial. The hour and the minute dial will correspond to 8.00pm. It is important to make
sure that if the time is set to 8.00pm then the mark on the inner dial must point to 20, not 8,
which would be 8.00am.
The time switch is programmed by pushing the captive trippers to the outer ring position for
the entire period that the chlorinator and pump are to be turned “ON”, i.e. each segment
corresponds to 15 minutes on the 24-hour dial. When the tripper is pushed inwards, the timer
is in the “OFF” position.

6. Circuit Breaker
The circuit breaker mounted on the front right-hand side of the EvoChlor chlorinator is designed
to trip out in the event of a power surge or overload. When tripped, the yellow centre button
will pop out, shutting down the unit. To reset, press the yellow centre button back in to resume
normal function.
NB: Turn o󰀨 the chlorinator at the power point before attempting to reset the circuit breaker.
Should the circuit breaker continue to trip, then a local Reltech distributor should be contacted.
7. Switch
This switch allows you to choose the timer operation mode for the chlorinator and pool pump.
Switched to the left position, Timer, enables the chlorinator and pool pump to turn o󰀨 and on
at the designated timer settings. The Manual selection, to the right, allows the chlorinator and
pump to work continuously until the switch setting is physically changed. The O󰀨 position in the
middle will turn power o󰀨 to the chlorinator and circulation pump.

6.0 MAINTENANCE
6.1 It is recommended that a pool water sample is taken to a pool shop and tested once per month
for analysis. Please refer to Pool Chemistry (section 2.0) for additional information.
6.2 The electrolytic cell operates most e󰀩ciently when it is clean. As a natural result of the
electrolytic process, which creates chlorine from salt molecules, calcium is attracted to the
titanium plates in the cell. The self-cleaning feature helps to inhibit such build-up and scaling.
However, the attraction of calcium and other minerals is inevitable, and eventually, it must be
removed.
6.3 The transparent housing of the cell allows easy visual inspections, and with correct water
chemistry, the cell will only need cleaning approximately every 3-6 months. In regions with
hard water (high calcium levels), more frequent cleaning may be required.
6.4 To clean the cell follow these instructions:
1. Turn o󰀨 power to the chlorinator and pump.
2. Remove the cell from the cell housing by loosening the cell collar and pull the cell out of
the housing. If required, disconnect the cell cable wires at the junction box underneath the
power pack (these must be re-connected rmly and tightly).
3. With the cell removed use a high-pressure hose nozzle to spray o󰀨 as much loose scale
as possible. Do not use any sharp or metallic objects to remove scale as this will damage the
cell.
4. If further cleaning is required, the cell needs to cleaned in a mixture of 1 part Hydrochloric
Acid to 10 parts water. Mix the acid solution in a bucket or tube that will t the cell.
5. iWARNING: Chemical Hazard - When mixing acid with water, always add the acid to
the water, never add water to the acid. When using the acid, ensure to use rubber gloves
and appropriate eye protection and follow safety directions on the Hydrochloric Acid label.
6. Place the cell into the cleaning solution submerging the plates and ensuring that the cell
head does not come in contact with the acid solution. Once the cell is clean, remove it from
the cleaning solution and rinse. Replace the cell into housing in a reverse manner to the
steps above.
6.5 Only qualied electrical technicians should service the power pack. For the nearest Reltech
recommended service technician, please contact us:
