CAUTION
This appliance may be used by children of at least 8 years of age and by persons with reduced physical,
sensory or mental capabilities or lacking experience or knowledge, if they are properly supervised or if they
have been given instructions on the safe use of the appliance and are aware of the risks involved. Children
must not play with the appliance. Cleaning and maintenance by the user must not be carried out by children
without supervision.
CAUTION
A means of de-energising all active poles (phase(s) and neutral) must be provided on the power supply,
upstream of the appliance, so that the product can be systematically de-energised before any technical
intervention. This device must be located close to the appliance.
CAUTION
CAUTION
If the power cable is damaged, it must be replaced by the manufacturer or its authorised distributor.
CAUTION
The BWT MANAGER CONNECT DUO cabinet must be positioned at a minimum distance from the pool basin
specified by the regulations applicable at the place of installation. In France, this distance is 3.5 metres.
However, if the power supply to the unit is specifically protected by a 30 mA residual current device, this
distance can be reduced to 2.0 metres (volume 2 below).

WARNING
It is strongly recommended that your electrical installation be equipped with a lightning surge
protection device. For any resulting damage to the electrical and electronic components of the BWT
MANAGER CONNECT DUO, the warranty shall be void.
2. General
2.1 Range and main functions
The BWT MANAGER CONNECT DUO analysers/controllers you have just purchased is a high-tech electronic
device, carefully designed and built for your pleasure and peace of mind. The simplicity, user-friendliness and
technicality of the BWT MANAGER CONNECT DUO will guarantee you perfect control of the water quality
of your pool or spa.
They are designed to regulate the pH and disinfectant chlorine content of swimming pool or spa water. The
free chlorine level can be measured directly (models equipped with an "amperometric" probe), or via the
measurement of the oxidation-reduction potential - ORP (models equipped with a "redox" probe).
The BWT MANAGER CONNECT DUO controllers are available in 4 models:
-For spas with a water volume of between 1 and 20 m3 outdoors or between 1 and 25 m3 indoors:
closed cell pH/chlorine control with 0.5 litre/hour pumps:
-For family pools with a water volume of between 5 and 110 m3 outdoors, or between 5 and 130 m3
indoors: pH / redox control with 1.5 litre/hour pumps
-For public pools with a water volume of between 50 and 300 m3 outdoors, or between 50 and 350
m3 indoors: pH / free chlorine control
oWith "open" free chlorine probe with 5 litre/hour pumps
oWith "closed" free chlorine probe with 10 litre/hour pumps
The elements of the BWT MANAGER CONNECT DUO for pools are pre-mounted on a rigid panel for
easy installation.
The BWT MANAGER CONNECT DUO for private pools is available optionally as a panel-mounted or free-
standing unit.
The BWT MANAGER CONNECT DUO for spas is delivered as a free-standing unit only.
Only spare parts and accessories corresponding to the characteristics of the BWT MANAGER CONNECT
DUO are permitted. Probes or interfaces that do not comply with the technical specifications in this
manual must not be used.
BWT MANAGER CONNECT DUO analysers/controllers are equipped with :
oa menu available in 7 languages (French, English, German, Spanish, Portuguese, Italian, Dutch)
oan on-board WI-FI module
o50 and 60 Hz compatible electronics
oIP65 sealed external quick connectors
oa silicone membrane keyboard
o1 x 4-20 mA input (temperature)
o2 end-of-bin entries
o1 self-powered relay output

4. Installation and connections
CAUTION
The installation and connection of the BWT MANAGER CONNECT DUO equipment should only be carried
out by trained and qualified personnel.
The installation must comply with the applicable standards and safety regulations!
metres (Volume 2 below).
CAUTION
Always switch off the mains supply before switching on the device or manipulating the outputs.
Never open the unit when it is powered up!
Maintenance and repairs must only be carried out by authorised and qualified personnel.
4.1 Choice of installation site
To ensure the safety of users and the proper operation of your BWT MANAGER CONNECT DUO, please
observe the following guidelines for installation:
➢The cabinet must be located at a distance from the pool in accordance with the regulations applicable
at the installation site
➢The appliance must be protected from frost and direct sunlight.
➢The ambient temperature should be between 0 and 50°C
➢The installation site must be properly ventilated, in particular to avoid corrosive atmospheres and
environments with high concentrations of solvent vapours
➢Choose an installation site that is free of vibration, on a stable, solid, clean and undistorted surface
(level).
➢The location of the cabinet must be compatible with the location of the product treatment tanks and
the injection points of the products in the hydraulic circuit: note the length of the tubing and follow
the instructions below
In case of non-compliance with these instructions :
➢The unit may be damaged
➢Measurements can be disrupted
➢The guarantee shall be void!
4.2 Wall-mounting of the cabinet
1. Turn off the general power supply
2. Check that the filter pump is switched off.
3. Close the hydraulic valves and set the filter valve to "closed".

4. Drill holes in the wall where the cabinet is to be mounted, corresponding to the diameter of the dowels
and respecting the centre distances specified in paragraph 3.3: 2 holes for the free standing bracket,
4 holes for the pre-mounted panel version
5. Insert the dowels with a hammer, then fix the base or panel by giving only a few turns to each screw
6. Once all the screws are in place, tighten them crosswise

4.3 Installation of tapping saddles for probes ("free-standing" version) and product
injections
Recommended for installation as a "free-standing" version:
In order for the values measured by the probes to be as representative as possible of the water in the
pool, the probes should be positioned between the pump discharge and the inlet to the filter's multi-
way valve. In any case, they should be located before any heater and before the injection of chemicals.
The injection of chemicals should be done after all devices, just before the water is returned to the
pool.
It is possible to mount the tapping saddles on a bypass circuit in order to isolate them hydraulically for easier
and faster removal of the probes ("no water pressure") and to leave the filtration running (especially during
active wintering).
