Page 6: Intended Use
As the accumulation of aluminium grinding dust produces a potential risk of explosion, the interior of the WNA-AL protected against sparking due to the explosion-proof engine and the grounded internal parts. The operator has to ensure that in the environment of the unit, such accumulations are not produced, e.g. -
Page 7: General Safety Instructions
3.2. General safety instructions WARNING Dangers arising from improper use / unauthorised operations. The operator must ensure that their authorised personnel are familiar with all the safety indications in this manual in advance. The operator is responsible for ensuring that all work is carried out by authorised and qualified personnel. - Page 8 ● First the filter unit as delivered must be transported to its destination. Then lift the filter unit off the pallet. Therefore use the lifting rings (B). Use appropriate lifting tools (forklift truck, transport crane,...) with a sufficient minimum load-carrying capacity. The filter unit must be secured against tilting and slipping when it is moved, lifted or put down.

5. Commissioning WARNING Dangers arising from a defective condition of the unit. Make sure that the measures described in this chapter are completed before the commissioning of the unit. All doors of the unit must be closed and all necessary connections must be attached before turning the unit on. -
Page 10: Connecting The Suction Line And Exhaust Air Line
Only operate the system if the necessary suction line is fitted. The suction line must be dimensioned according to the application. If this has not already been carried out by TEKA, a suitably qualified employee must be consulted. If the suction line includes extraction elements (e.g. -
Page 11: Electrical Connection
According to the temperature and the relative air humidity of the extracted air, the exhaust air can also be moisture. In every case, the exhaust air has to be returned outside so that the work-ing space is not too highly moisture which can lead to the formation of condensate. 5.2. -
Page 12: Water Supply / Water Quality
5.3. Water supply / water quality Due to the moistening of the outlet air, the water is little by little extracted from the filter unit. That is why water must be regularly be refilled. It is ensured by the automatic monitoring of the water level and the automatic refilling through the electrovalve. -
Page 13: Additive: Corrosion Protection "Hebro®Protect 95-103" (Optional)
5.3.1. Additive: corrosion protection "hebro®protect 95-103" (optional) A corrosion-protective agent should be added to the water in order to prevent the formation of rust, especially in case of separation of acidly reacting substances. This is primarily required when separating metal dust and scale dust. If you ordered a corrosion-protective agent when ordering the unit, add it to the water when commissioning the unit. -
