7.2. Blower (option)
Only 3-phase blowers require checking.
- Switch the blower on and immediately off again.
- The direction of rotation of the blower must correspond with the indicated direction (see
direction of rotation of the arrow).
To change the direction of rotation: interchange 2 phases in the connection.
Note:
An incorrect direction of rotation gives an insufficiently strong air flow.
7.3. Air knife
Check whether the air flow out of the outflow opening of the air knife is adequate and constant.
You can feel this using your hand.
7.4. System pressure
There is a test nipple on the air knife. A manometer (range 0–400 mbar) can be used to
measure the system pressure. The system pressure is specified in an appendix.
A digital manometer has either been supplied or can be supplied upon request.
8. Maintenance
Warning:
Disconnect the power supply before carrying out work on the unit.
8.1. Air knife
Regularly check the air slot for clogging and clean it if necessary.
Cleaning the air slot:
- Disconnect the air connection and blow clean the air slot and air knife with compressed air.
- If necessary, remove any dirt with a soft object or brush.
Do not use metal objects as these may damage the air slot.
8.2. Anti-static bars
Keep the anti-static bar clean.
Clean with a hard non-metallic brush in the case of fouling.
Clean with isopropyl alcohol when they are heavily fouled.
Allow the anti-static bar to dry completely before operating it again.
Note:
Do not damage the emitter points, because this reduces the ionizing effect.
