NOTICE
Overview of an EVAstream configuration
2.2 General safety instructions
Follow the NEN1010 guidelines. Follow the specific installation requirements of IEC 60364-7-702: 2010
(Electric low-voltage installations - Part 7-702: Requirements for special installations, spaces, and
areas – Swimming pools and fountains). Install the controller in or outside of zone 2 (NOT in zones 0
or 1) according to IEC 60364-7-702: 2010. The power supply must be equipped with an earth leakage
circuit breaker (ELCB) with a nominal differential current ≤30mA.
The EVAstream was developed as a counter-current swimming machine for use in a swimming pool.
Use for any other purpose is not permitted. Requests for exceptions to this should be submitted
to the manufacturer for technical analysis. Only after written approval by EVA Tech B.V. may the
EVAstream be applied in any other way than as prescribed in this document.
The general terms and conditions of EVA Tech B.V. apply to all our offers and agreements. EVA Tech
B.V. expressly rejects the applicability of the general (purchasing) conditions of counterparties. The
warranty provisions of the EVAstream and the general terms and conditions of EVA Tech B.V. can be

4 Symmetrical placement EVAstream
The importance of symmetrical placement of the EVAstream
To create the optimal swimming experience for the customer, it is important to think carefully about the
positioning of the EVAstream in the design phase, for example in relation to elements such as stairs and
platforms. Such ‘obstacles’ can cause a less pleasant swimming experience. For optimal water flow, the
EVAstream should be placed in the middle of the pool wall in a symmetrically designed pool.
Blockages in the water circulation
Suppose you have placed a staircase in the corner of
the pool. As a result, the circulation of the flow is not
equal on both sides of the pool, because the stair-
case influences the flow. The flow of the EVAstream
is still just as powerful, but the user experiences the
current as if it were faltering.
Flow with asymmetrical placement
When a turbine is not placed symmetrically in the
pool, the circulation of the current is not equal on
both sides of the pool. The current of the EVAstream
is still just as powerful, but it creates a kind of vortex
in the middle of the pool.

5 Mounting the EVAstream
1. EVAstream turbine
Water suction takes place through the grids
around the machine. Always make sure that the
suction parts are completely free of obstacles.
These parts of the machine must not be closed or
blocked in any way (EN 13451-1/3).
For instructions on how to mount the turbine, go to
5.4.
2. Motor Contol Unit
The motor control unit (MCU) of the EVAstream is
placed in the technical area near the pool (a dry
and condensation-free environment, zone 2).
Ensure that the MCU is placed with the cable
glands facing down.
3. EVA Piezo
Start/stop or adjust the speed of your EVAstream
swimming workout at the touch of a button, right
from the pool.
For instructions on how to mount the EVA Piezo, go
to 5.3.
4. ON/OFF switch
If the EVAstream is permanently connected to
230V mains, the installation must additionally be
equipped with an on/off switch mounted near the
swimming pool where the EVAstream is located.
5. EVA Experience web app
Use the EVA Experience web app to manage the
EVAstream.
For instructions on how to set up the tablet en-
vironment, please refer to the manual Eletrical

6 Create the best swimming zone
The customer’s swimming experience fully depends on the correct placement of the turbine. By
placing the turbine at exactly the right height, you ensure that the current reaches the swimmer’s
chest.
1. Determine swimming zone
You start by determining the swimming zone of the user. Did he or she choose an EVAstream Fit, Pro
or Max? Then you can use the images to determine exactly what the user’s swimming zone is. This is
always the same per type, regardless of the height of the swimmer.

2. Turbine placement EVAstream 250 mm
For the positioning of the turbine we advise 250 milimeters (centre of the turbine) below water level. Mount
the EVAstream horizontally in the wall, in the middle of the wall.
3. Check the swimming zone
The flow is directed at the torso and not at the head, so that there is free breathing space while
swimming. The current is also wide and stable enough to encompass the entire body. When you swim
over the water flow, or you get water in your face, the turbine has to be adjusted.
4. Adjust the turbine if necessary
You can adjust the turbine a little higher or lower with the adjustment jig at the customer’s request. The
turbine can be adjusted a maximum of 2 degrees downwards or 3 degrees upwards using adjusting bolts on
the side. This way you ensure that every customer has an optimal swimming experience.

7 Check before
7.1 Check before switching on the EVAstream
The machine and the basin in which it is placed must be completely free of obstacles (small and
large) before the machine is switched on.
The EVAstream machine may only be operated underwater. Always fully submerge the machine
before use. Serious and permanent damage to the machine can occur if the EVAstream is not
submerged during use.
7.2 Check before using the EVAstream
Always read the included user manual before using the machine. The user manual is also published
online at www.evastream.nl.
7.3 Maintenance and repairs
The EVAstream comes equipped with a connection cable with plug. If the EVAstream is permanently
connected to 230V mains, the installation must also be equipped with a main switch/isolation
switch in the space where the Motor Control Unit is installed. During maintenance and work, this
switch must be used to de-energise the installation.
In the space where the swimming pool with EVAstream is located, an on/off switch must be mounted
for the user (in case of a permanent connection to 230V mains). Users should use this on/off switch
to turn on the machine right before use and turn it off immediately after use.
Never open the turbine. Any form of maintenance or repair must be carried out at the factory of EVA
Tech B.V. In case of an established defect, the machine must be dismantled and transported to the
EVA Tech B.V. factory in the Netherlands in agreement with the supplier.
Any attempt to open the machine will cause permanent and irreparable damage. Warranty expires
immediately after any attempt to open the machine.
8 Disposal
8.1 Decommissioning
Electrical shock hazard. Risk of electric shock and injury. Make sure to disconnect the product from
the mains cable before decommissioning.
1. Switch off the power.
2. Switch off the power around the swimming pool.
3. Disconnect the mains cable.
4. Disconnect all other cables.
8.2 Disposal
Before disposing of the different materials, separate them into recyclables, normal waste and special
waste. Comply with local legal regulations and provisions when disposing the product and the
individual components. A product marked with the WEEE symbol must be sent for separate collection
of electrical and electronic devices. Contact your supplier for more information.

- Open-air swimming pool < 20 m2 – Free available chlorine (FAC): 0.5 ≤VBC ≤5.0 mg/L
- All basins – Bound available chlorine: < 0.6 mg/l
- The basin and the available accessories must be free of electrolysis.
- Installation housing must be properly earthed to prevent electrolysis.
- Cyanuric acid: ≤100 mg/l

Unintended uses
- Not for use in potentially explosive areas.
- Not for use in an aggressive environment (gases, acids, vapours, substances, oils).
- Not for use in dirty water.
- The turbine should not be used above water.
- Depending on the type of concrete, the installation shaft must be protected. When using concrete with
high chloride and sulphate constituents (e.g. Thermotec), the back of the installation shaft must be
protected against these harmful substances with a PE film (building protection film).
