2.7 Optional equipment
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.
Some precautions are general and may not apply to your optional equipment.
Precautions
1. Make sure that all electrical wiring is installed in compliance with the applicable regulations.
2. Installation must always be performed by a qualified technician.
3. Installation must be carried out in compliance with the circuit diagrams and connection drawings provided.
Available options
• Electronic drain (EWD)
The electronic drain is optional on the WSD, the DD filter and the PD filter.
The electronic drain is a zero-loss, electronically operated drain valve, specially designed to drain oil and
water. A sensor detects the liquid level. If the level exceeds a preset value during a fixed programmed
time, a solenoid valve is activated and the condensate is discharged via drain outlet (6). Next, the solenoid
valve closes and condensate is collected again. This way, the loss of air is reduced to a minimum.
If the micro-controller of the EWD registers a malfunction, the automatic drain valve will automatically
change to alarm mode, visible on the display (5). This alarm signal can be relayed via a potential-free
contact.
