10 Maintenance
10.1 Safety
Maintenance work may only be carried out by qualified personnel.
WARNING
Risk of injury due to incorrect maintenance or troubleshooting
4
Check the proper functioning of the product, especially the safety features, after every mainte-
nance or troubleshooting operation.
NOTE
Incorrect maintenance work
Damage to the ejector!
4
Always switch off supply voltage before carrying out any maintenance work.
4
Secure before switching back on.
4
The ejector must only be operated with a silencer.
4
Before carrying out any work on the system, ensure that the ejector’s compressed air circuit is vented to at-
mospheric pressure!
10.2 Cleaning the Ejector
1. For cleaning, do not use aggressive cleaning agents such as industrial alcohol, white spirit or thinners. Only
use cleaning agents with pH 7–12.
2. Remove dirt on the exterior of the device with a soft cloth and soap suds at a maximum temperature of 60° C.
Make sure that the silencer is not soaked in soapy water.
3. Ensure that no moisture can reach the electrical connection or other electrical components.
10.3 Replacing the Silencer Insert
Heavy infiltration of dust, oil, and so on, may contaminate the silencer insert and reduce suction capacity. Cleaning
the silencer insert is not recommended due to the capillary effect of the porous material.
If the suction capacity decreases, replace the silencer insert:
