7.1. Housing
Before commissioning the unit, thoroughly clean the inside of the housing and inspect it for
damage. The method of cleaning (e.g. broom-clean, sterile, etc.) is determined by the site
conditions, operating requirements and other specifications.
Inspect the doors for tightness. Test the locks to ensure that they are working properly and
adjust them, if necessary.
7.2. Fan motor
Check the fan motors as follows:
- V-belt correctly tensioned and aligned with pulleys?
- Securing screws of pulleys properly tightened?
- Vibration dampers unobstructed? Fan parts with spring vibration dampers are secured with
transport securing devices (marked in red). These must be removed prior to commissioning.
- Check the motor connection and the supply voltage.
- Have the protective earthing conductor tested on site by a qualified electrician.
- Close all access doors and check that they are properly closed.
- Fan parts with spring vibration dampers are secured with transport securing devices (marked
in red). These must be removed prior to commissioning.
- Check the unit for damage, dirt and corrosion and clean it, if necessary. Check all securing
screws for proper fixture and retighten them, if necessary.
- Check the flexible connectors for leakage.
- Check the vibration damper function.
- Check the bearings by measuring the temperature and listening to unusual noises.
- Replace defective bearings without delay.
- If there are unusual grinding noises, the bearing is defective. Always replace bearings in pairs.
The fan bearing is lubricated for life (unless it features lube points). Bearings with lube points
must be lubricated at prescribed intervals. Use the following lubricants: SKF 28, MOBILUX 3
or equivalent product
- If the bearing is equipped with lubrication nipples, lubricate them at the prescribed interval.
For lubricant quantities, grades and intervals, refer to the manufacturer's instructions.
