Page 6: Safety Precautions
Instruction book Safety precautions Safety icons Danger: Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Warning: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Notice: Indicates a potential situation which, if not avoided, might result in property damage or in an undesirable result or state. -
Page 7: Safety Precautions During Installation
Instruction book • Installation, operation, maintenance and repair work must only be performed by authorised, trained, specialised personnel. • Before carrying out any maintenance, repair work, adjustment or any other non-routine checks, stop the device. In addition, the power isolating switch must be opened and locked. Safety precautions during installation •... -
Page 8: Safety Precautions During Operation
Instruction book Safety precautions during operation Warning: All responsibility for any damage or injury resulting from neglecting these precautions, or non-observance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer. -
Page 9: Dismantling And Disposal
Instruction book • A warning sign bearing a legend such as "Work in progress - do not start" shall be attached to the starting equipment, including all remote start equipment. • Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no one checking or working on the machine. - Page 10 Instruction book Disposal of electrical and electronic appliances (WEEE) This equipment falls under the provisions of the European Directive 2012/19/EU on waste electrical and electronic appliances (WEEE) and may not be disposed as unsorted waste. The equipment is labelled in accordance with the European Directive 2012/19/EU with the crossed- out wheelie bin symbol.

Page 11: General Description
Fluoroelastomer (FKM) diaphragm. • Remote alarm connection for warning. • Tank in aluminium with a treatment for operating with aggressive condensation. • Secondary condensate input that is ideal for low attachment points. (Not for NED 4L and NED 6LC.) 2920 7213 30... - Page 12 Instruction book Operation Figure 1: Condensate drain, standby mode and discharge mode The drain is connected to the point where the elimination of the condensate is required (tank, filter, dryer, etc.), by means of the connection supplied (1). The accumulation tank (2) collects the condensation and the diaphragm (3) keeps the drainage hole closed thanks to the pressure exerted on its surface.

Page 13: Control Panel
Instruction book Control panel Description NED 4L The control panel on top of the drain includes a multifunction button and two state display LEDs. • Green LED This LED is on when the drain is powered and during its normal function. -
Page 14: Operation Logic
Description Green LED Power status indicator Red LED Alarm indicator Multifunctional test button Operation logic NED 4L Power on The CPU of the drain starts-up and loads the internal data. Green LED Blinks 3 times. Blue LED Blinks 2 times. - Page 15 Instruction book The drain is ready to operate: activation through floater movement. Every 30 minutes a routine to keep the drain clean from oil/ condensate residuals starts. Green LED Blue LED Purge valve On until the condensate chamber is almost empty. Cleaning routine If the floater is stuck at the top, after 10 sec the drain starts a cleaning operation.
- Page 16 Instruction book NED 6LC - NED 350L Power on The condensate drain is powered on. The green and red LED flash one after the other for 5 seconds. Valve Alarm Normal operation The condensate drain is operating normally. Valve Alarm Supply voltage missing The condensate drain is disconnected from the power supply.
- Page 17 Instruction book Flashing slowly Valve On for a maximum of 20 seconds. Alarm Cleaning routine 1 Even if the valve is opened, the minimum level is not reached within 20 seconds. The condensate drain tries with repeated on/off cycles to unblock the situation probably caused by clogging. Flashing slowly 1.

Instruction book On for a maximum of 3 seconds. Valve On for a maximum of 3 seconds. Alarm Reset When a reset in an alarm state is required. If the problem persists, the alarm state will be reactivated after a short period. Green and red LED sequence and then the green LED is on. - Page 19 Instruction book Option Description • 3 sec: open • 60 sec: closed Total routine time: infinite External free contact opens. Continue with step 7. 7. Is water discharging? Option Description Drain works Drain remains in cleaning routine 2 until drain ejects water or is serviced/repaired.

Page 20: Installation
Instruction book Installation Installation proposal Danger: Installation or maintenance work can only be carried out by trained and qualified staff who must follow the procedures of this manual and use proper safety and protection equipment. Danger: Disconnect the electrical power supply as well as the air plant system before any installation or maintenance works. - Page 21 Instruction book The condensate drain must be mounted vertically, with the inlet upward and with a maximum of ± 5° inclination. The diameter of the inlet pipe must be at least 12 mm. With the condensate drain connected directly to the line, it is preferable to modify the plant in such a way as to deflect the air flow and to make it possible for the condensate to collect in the lower point.
- Page 22 Instruction book Do not connect only one condensate drain to two points with different pressures in such a way as to avoid the creation of by-pass flows. In case there is no adequate slope, it is necessary to use a secondary pipe for air compensation. 2920 7213 30...

Danger: In case of AC supply, a reliably accessible separator must be provided close-by (e.g. power plug or switch), which separates all current carrying conductors. Danger: If the potential-free contact carries voltage that is dangerous in the case of contact, a corresponding separator must also be provided.
