NOTE!
Ensure that all components of the pool system which may come into contact with the pool water are resistant to salt water.
In particular, make sure that the filtration pump is resistant to salt water.
Note that even water with a low salt content can be corrosive, and take this into account when selecting components for use
(e.g. steel ladders etc.).
Necessary qualification:
The Salt Relax POWER must be installed by a specialist with both in-depth knowledge of swimming pool construction and in-depth
knowledge of the installation of electrical and electronic devices!
Danger caused by electrical current
The Salt Relax POWER is live as soon as voltage is applied to the power input. The chlorine production cell or additional functions
may be switched on or switched over. Contact with live components can lead to an electric shock.
This may result in serious or even fatal injury and damage to material assets, and the following therefore apply:
All such tasks must be carried out exclusively by adequately trained and experienced personnel!
The device must always be de-energised before performing installation and maintenance work on it!
Secure the device against being switched on while work is being performed on it!
Additional modules must be installed/removed in de-energised state!

3.1 Wall installation
Notes on installation:
The device must be mounted on a flat, vertical surface protected against moisture.
There must be adequate free space around the device to allow correct operation and maintenance of the device.
It must be possible to remove the front cover of the device.
A space of at least 20 cm below and to the side of the device is required for routing cables.
A wet room Schuko socket (two pin earthed plug) with continuous current is required at a distance of not more than 1.5 m.
All cables must be routed without kinks and chafing points.
Avoid exposure to direct sunlight, heat radiation, frost and moisture. Ensure adequate ventilation.
No live cables, contactors, electric motors etc. in the immediate vicinity.
The installation location should be as close as possible to that of the chlorine production cell (note cable length).
The Salt Relax POWER with the mounted holders can be used as a template for drilling by holding it up against the mounting location and
marking the position of the drill holes on the wall.
3.2 Electrical connection
The Salt Relax POWER has been designed and constructed according to the applicable regulations. It was carefully inspected before leaving the
factory and left the factory in a safe and technically flawless condition.
The equipment can only be operated safely if all of the instructions contained in this manual are followed.
The supply voltage for the device must not exceed 110 - 240V/60 Hz. The permissible operating temperature range is from 0 to 50 OC, the permissible
humidity level 0-90 %.
As is standard practice for electrical connections, ensure that all plug-in connections and cable grommets are protected against water.
3.2.1 Supply via the filter control
If the Salt Relax POWER is activated via an external timer (e.g. filter control), it must be ensured that the circulating pump and the Salt Relax POWER
are precisely synchronised. The Salt Relax POWER must be switched off if there is no flow of water.
Make sure that the external timer (e.g. filter control) meets the performance requirements of the Salt Relax POWER!

3Installation
6
In order to supply the Salt Relax POWER with power via a filter control as shown in the diagram above, the mains power plug supplied can be
dismantled as shown below.
Attention:
Connection of the Salt Relax POWER in this way must be performed by a specialist technician with in-depth knowledge of the
installation of electrical and electronic devices!
When connecting the power supply cable of the Salt Relax POWER to the filter control, it is imperative to follow the instructions
(connection diagram) provided with the filter control.
3.2.2 Salt Relax POWER as filter control
As standard, the Salt Relax POWER can be used as a controller for the filtration pump; please refer to the section Filtration. In this case, the mains
power plug of the device is connected to a water-protected mains socket with a 30 mA residual current circuit breaker.
See also the information in the chapters Filtration, Configuration and Connecting terminals.
3.3 Connecting the chlorine production cell
When connecting the cell supply cable to the control unit, make sure that the cable is inserted firmly at the points provided, with no loose contact. The
cap nut of the plug-in connection must be securely tightened. If this is not the case, there is a risk of overheating at this connection.
Also insert the second, thinner cable (gas flow sensor) of the chlorine production cell carefully into the connection point provided (see Connections
and fuses on the Salt Relax POWER).
3.4 Connecting the temperature sensor
The temperature sensor cable is routed into the Salt Relax POWER through the cable grommet mounted at the factory on the underside of the
housing front cover (see "Installing a cable grommet") and connected as described.

3Installation

3.5 Installation diagram
The illustration shows connection of the Salt Relax POWER via the filter control.
The holder for electrodes and temperature sensor can also be attached directly inside the chlorine production cell with adhesive.
NOTE
We recommend that the cell is always installed in the bypass. Installation in this way is mandatory if the flow rate exceeds 15 m3/hour,
in order to avoid load losses. Installation in the bypass makes it much easier to carry out maintenance on the chlorine production cell
and the optionally installed sensors.
If you install the cell in the bypass, you should fit a non-return valve in the bypass line after the cell in place of a manual valve, in order
to rule out the danger of accidental actuation.
It is imperative to note that the chlorine production cell must always be the last element installed on the return line to the pool (see sketch above).
To enable use of the integrated gas flow sensor, the cell must be positioned vertically. The sensor will only function correctly if this is the case. If
installation in vertical position is not possible, the paddle flow switch supplied with the device must be used!
Please note that the water flows through the chlorine production cell as shown in the diagram and not in the reverse direction.
The chlorine production cell itself is attached inside the bypass piping with adhesive. Depending on the diameter of the pipe, it may be necessary to
use the reducer supplied.
NOTE
When inserting the cell into the cell holder, make sure that the cell blades are positioned in the direction of flow of the water. This
ensures that the blades offer the lowest possible resistance to the water flowing through the cell.

3Installation
8
3.6 Installing the additional flow switch
It must be ensured that the chlorine production cell is only in operation when pool water is flowing through it.
The Salt Relax POWER is equipped with a gas flow sensor integrated in the chlorine production cell. This sensor only functions if the cell is installed in
vertical position. If, for technical reasons, it is not possible to install the cell vertically, or if a double dosing lock is to be used, the paddle flow switch
provided can be installed; see installation diagram above.
This paddle sensor must be installed directly in front of the chlorine production cell. The electrode holder supplied has a drilled hole for the paddle
switch on its underside and is used as the holder for the paddle switch. Ensure that the holder is mounted in the bypass line in front of the cell.
NOTE
When installing the paddle flow switch, it is essential to ensure that the arrow printed on the switch matches the direction of flow of the
water!
Connecting the paddle flow switch in the Salt Relax POWER
An additional cable grommet must be created in order to connect the paddle flow switch inside the device. To do this, follow the instructions in
"Installing a cable grommet."
3.7 Earthing
Note that even water with a low salt content can be corrosive. To minimise the corrosive effect, BAYROL recommends the installation of a "sacrificial
electrode" in the pumping system of the pool. Ask your specialist swimming pool dealer for details.
NOTE
When selecting components (e.g. steel ladders etc.), always take into account that corrosion may occur. It is essential to select
components which are suitable for use with salt water. BAYROL expressly refuses to accept liability for damage caused by corrosion!

When filling your pool from scratch, it should be noted that initial adjustment of the water can take some time. You may need to add water care
products (e.g. pH-Minus) several times within the first 1 - 2 weeks.
Please consult your specialist swimming pool dealer if you are uncertain about the adjustment of the water quality in your pool.

3Installation

Please ensure that the values given in the table are complied with beyond the end of the bathing season by regularly testing and if necessary
correcting the water quality. The required test sets and the respective water care products are available from your specialist BAYROL swimming pool
dealer.
TIP
Check the cyanuric acid content when you check the salt content. These two values usually drop at the same time.
3.8.2 The right salt
Use only salt intended for use in swimming pools with salt electrolysis systems. Such salt has a high level of purity and is usually sold by specialist
swimming pool dealers in 25 kg sacks.
Never use rock salts, de-icing salts, salts with sodium ferrocyanide, salts with separating agents or iodised salts!
The Salt Relax POWER is suitable for operation with sea water.
3.8.3 Calculating the pool volume
Rectangular pools Oval pools
Length (m) x width (m) x depth* (m) = pool volume (m3) Longest length (m) x greatest width (m) x depth* (m) x 0.89 = pool volume (m3)
Round pools Figure-8 pools
Diameter (m) x diameter (m) x depth* (m) x 0.79 = pool volume (m3)Longest length (m) x greatest width (m) x depth* (m) x 0.85 = pool volume (m3)
*Depth = average depth of the water
3.8.4 Calculating the amount of salt to add
The amount of salt to be added to a freshly filled pool (salt-free water) is calculated with the following formula:
Desired salt content (g/l) x pool volume (m3) = amount of salt to be added (kg)
The amount to be added to water which already contains salt is calculated with the following formula:
[Desired salt content (g/l) –existing salt content (g/l)] x pool volume (m3) = amount of salt to be added (kg)
3.9 Adding the salt to the pool
Before adding the salt:
Check that the pH value of the water is within the optimum range (pH 7 to pH 7.4).
Also check that the water in the pool is free from metals and of perfect quality. If necessary, carry out shock chlorination of the water. It is best to do
this when the water is at a temperature of at least 20OC.
Adding the salt:
Switch the circulating pump on and open all inlets and outlets to ensure the greatest possible flow of water through the pool. If fitted, also activate the
bottom drain. Pour the salt directly into the pool. Do this at a point where there is high flow, e.g. at the inlet jets. Ideally, swirl the salt around with a
long-handled broom to accelerate the dissolving process. After adding the salt, run a filtration process continuously for at least 24 hours to ensure that
the salt is fully dissolved and evenly distributed.

4.2 Quick access to salt electrolysis
The Quick Access function allows rapid activation of the Boost function and easy adjustment of the output of the chlorine production cell.
Electrolysis output
Set the output (large flashing % value) with / keys of your Salt Relax POWER. Adjust the system
output to suit the requirements of your pool.
This setting corresponds to the setting in the Electrolysis menu.
Boost
Activate the Boost function by using / to select On and confirming with .
The Boost function increases chlorine production to the maximum value (100%) for the following 24 hours of
filtration time, after which it automatically returns to the programmed filtration cycle. In most cases, this is
sufficient to bridge times of increased chlorine requirement. If Salt Relax Pro is controlled via the external
timer, please ensure that the timer runs continuously for 24 hours.
Note
If your pool needs a chlorine shock, we recommend that you administer it by adding chlorine
manually.

Intelligent mode
This mode uses the two operating parameters desired water temperature and min. filtration time per day
(min. 2 hours to max. 24 hours). Filtration is activated for at least 10 minutes every two hours in order to
check the water temperature.
The selected minimum filtration time is split up so that spread over the day, filtration is switched on and off
for equal amounts of time. If the desired temperature is not reached within one switch-on time, this switch-on
time is automatically extended. The extra time is subtracted from the following filtration cycles, whereby the
first 10 minutes of each filtration cycle are run in every case.

Filter cleaning (available in all operating modes)
This menu is used to facilitate backwashing of the sand filter.
As soon as the menu is activated in one of the filtration modes (Manual, Automatic, Heating, Smart,
Intelligent), the chlorine production cell is switched off.
Now proceed as follows:
- Using the / keys, set the filtration pump to Off
- Set the valve of your filtration pump to Backwashing.
- Switch the filtration pump back on again (On). You can follow the expired backwashing time on the counter.
It is imperative to ensure that your filter is adequately backwashed!
- After an appropriate backwashing cycle, switch the filtration pump off and reset the valve to Filtration. If
desired, you can now run a rinse cycle. The process is the same as for backwashing, but the valve is set to
Rinse.
- When is pressed to exit Filter Cleaning, the system switches back to the programmed mode.
NOTE!
BAYROL recommends that you select the maximum filtration times. Long filtration runtimes ensure high filtering performance of the
sand filter and allow adequate production of the disinfection agent.
If filtration runtimes are too short, this will inevitably cause problems with the disinfection of the water (e.g. algae growth etc.)

Set the output of the chlorine production cell to 0 –100% using / . Adjust the production capacity
of the system to suit the requirements of your pool.
This setting corresponds to the setting in the menu Quick access.
Salinity
The current salinity is displayed here. This display should be regarded as a good indication rather than an
exact measured value. In case of doubt, the salinity should always be established by testing a water
sample and the display then calibrated.
If the Salinity line is confirmed with , a message is displayed indicating the internal measurement of
the cell status. Once this internal measurement is concluded, the display can be calibrated if required.
Calibrating the salinity display:
The current measured value and the required (actual value

The Boost function increases chlorine production to the maximum value (100%) for 24 hours, after which
it automatically returns to the programmed filtration cycle. In most cases, this is sufficient to bridge times
of increased chlorine requirement.
Note
If your pool needs a chlorine shock, we recommend that you administer it by adding
chlorine manually.
Switch-off temperature
