8.4 Replacing the nebulizers
To replace a complete nebulizer set, first ensure that the high-pressure system has been switched off
and that the high-pressure line has been relieved. Also make sure that the power supply to the control
unit has been disconnected.
Replacement procedure
• Disconnect the hydraulic supply line via the quick coupling.
• Disconnect the electrical supply line via the quick coupling.
• Loosen the connections to the bracket.
• Fasten the replacement device in reverse order, making sure that no water has got into the electrical
connection.
• Restart the system and check the spray pattern.
NOTE!
Air in the stub / droplets at cut-off point
On commissioning the replacement device, it must be ensured that the nebulizer can be shut down
without droplet formation only after switching on and off multiple times (using the set point adjuster)
or after several hours. Protect or cover goods and/or devices where necessary.
This is due to air in the replacement device's high-pressure system. As soon as the air has been flushed
out, drip-free switch-off must take place and the device switches off permanently without dripping.
CAUTION!
Leakage check
Once the system is back in operation, look out for any leakages. Check the system occasionally over
the next two days.
