***** preliminary data

Lighting technology
Wide beam light distribution
Half beam angle 64°
When designing a lighting installation under water, note that the amount of light absorbed by the water depends on the clarity of the water.
Lighting intensity and brightness are less than with a free burning floodlight.

Overvoltage protection

The electronic components installed in the luminaire are protected against overvoltage in accordance with DIN EN 61547.
To achieve an additional protection against e. g. transients, etc. we recommend separate overvoltage protection components.
You can find them on our website at www.bega.com.

Installation

The floodlight may only be operated underwater in non-accessible areas of pools.
The electrical connection must be made outside the water with the appropriate safety class and protection class on the floodlight connection line.
Note correct configuration of the mains supply cable. Make mains supply connection at the brown (L), blue (N) and green-yellow lead ( ****).
The connection of the control cables is achieved by means of the both leads marked with DALI.
In case these leads are not used the luminaire will be operated at full light output.
Pre-mount two mounting screws suitable for the installation surface at 120 mm intervals in the desired position.
Insert the floodlight with the bracket into the mounting screws and fasten.

Adjust the floodlight:
Undo hexagon socket screws (wrench size 6 mm) and set the desired beam direction. Tighten the hexagon socket screws evenly.

Cleaning · Maintenance

Clean luminaire regularly with solvent-free cleansers from dirt and deposits.
Do not use high pressure cleaners.
To avoid surface damage to the floodlight, the water must have a neutral pH value and be free from substances that cause metal corrosion.

Please note:
Do not remove the desiccant bag from the luminaire housing.
It is needed to remove residual moisture.

Replacing the LED module / Power supply unit

The designation of the LED module is noted on a label in the luminaire.
The light colour and light output of BEGA replacement modules correspond to those of the modules originally fitted.
The module can be replaced by qualified persons using standard tools.
LED are high-quality electronic components!
Please avoid touching the light output opening of the LED directly during relamping.
Disconnect the system from the power supply.
Loosen the fastening screws of the floodlight bracket at the installation base and remove the floodlight bracket backwards from the mounting screws.
Lift the floodlight above the water level and clean it (see Cleaning · Maintenance).
Open the floodlight:
To do this, loosen the six hexagon socket screws (wrench size 4 mm) on the back and remove the trim ring.
Remove the gasket, glass and reflector.
Replace LED module.
Follow the installation instructions for the LED module.
To replace the power supply unit, loosen the five hexagon socket screws (wrench size 4 mm) and lift off the connection housing.
Replace the LED power supply unit.
Check gaskets and replace as needed.
The floodlight housing must be completely clean and absolutely dry.
Replace the connection housing and fasten.
Tighten the screws evenly.
Insert the reflector, glass and gasket.
Replace the trim ring and tighten the screws evenly in a crosswise pattern.
Tightening torque = 3,7 Nm
Carry out a function test outside the water.
Insert the floodlight with the bracket into the mounting screws and fasten it.

Accessories
