Option: No loss condensate drain (NLD)
Electronic drain discharge NLD is the new discharger applicable to any
compressed air systems. It eliminates the condensate without wasting
compressed air.
Electronic drain discharge starts automatically, without the need of any
adjustment. The condensate discharge occurs to the use of an electronic sensor,
which detects the amount of condensate in the integrated water collecting tank.
The level sensor drives start and duration of the drainage, so preventing any
wasting of compressed air.
At the end of installation, put the system under pressure and push the TEST key
repeatedly to eliminate the air bubbles contained in the discharger inlet fittings.
If the discharger not operate correctly, try to act on the TEST key to clean the mesh filter.
Never remove the discharger body. If the malfunctioning persist, contact our Customer
Service.
Before carrying out any work on the electrical parts, make sure that the main switch
interrupts the electricity supply to the dryer and then affix appropriate warning signs to
avoid the machine being reconnected to the electricity mains!
