ADJUSTMENTS

Electronic unit:

• The detection distance can be adjusted from 5 - 22cm using the potentiometer "GAIN" f (fig. I)
located on the electronic unit.
• We do not recommend using the minimum or maximum positions.
• The duty flush g (fig. I), is programmed to flush automatically for 60 seconds every 24 hours
after the last use. This can be cancelled or programmed to flush 12 hours after the last use by placing
the connecting pins in line with the desired programme (fig. K).
c: Safety transformer PRI: 220-240V~ / SEC: 12V~
d: LED diagnostic aids
e: Terminal connectors
f: Adjusts the detection distance
g: "Duty flush" pin connectors
Adjusting the flow rate (fig. L):
• The flow rate is pre-set at the factory at 3 lpm (at 3 bar).
• The flow rate can be adjusted directly on the flow straightener using a 2.5 mm Allen key:
- notch 1 = 3 lpm (at 3 bar)
- notch 2 = 4 lpm (at 3 bar)
- notch 3 = 5 lpm (at 3 bar)
ANTI-SCALDING SAFETY VIA MAXIMUM TEMPERATURE LIMITER (mixers)
Conventional side temperature selection lever (fig. M):
The product is delivered with the maximum temperature limiter engaged.
To override it:

The temperature limiter is fixed in position o at the factory. It is possible to change it to position n
to limit the temperature, or remove it to override the limiter:
• Isolate the water supply.
