For this,original drill bits and pipe duct seals by KESSEL must beused (KESSEL drill bits DN 50 - DN 150, item No. 50100,KESSEL pipe duct seals:DN 50 item No. 850114DN 70 item No. 850116DN 100 item No. 850117DN 125 item No. 850118DN 150 item No. 850119Adapter plateLug to hookin the control lineControl lineAir hoses to the compressed air syphonsLocking bracketDrilling should be carried out on surfaces that are as planeas possible.To provide an optimum seal for the drilled hole, the clearancebetween the edge of the drilled hole and uneven contourshould amount to at least 15 mm so that the seal circumferentiallybutts evenly against the drill hole.• VentilationPlants with closed cover are aerated and ventilated via thepenstock of the drainage plant. An additional ventilation linein DN 100 can be connected to the dome. For this purpose,the appropriate drill bit and pipe duct seal by KESSEL mustbe used (see illustration page 5). KESSEL recommends theuse of an activated carbon filter to avoid any unpleasantodours.The control line and the ventilation hose must be laid in thecable conduit between valve block and control unit (seeProcedure)Procedure:- Open the locking bracket on the valve block inside the tank- Remove the valve block from the adapter plate- Pull the grey ventilation hose and control line through thecable conduit- Connect the ventilation hose on the valve block using aquick-action coupling (see 4.11 Point 5)- Insert valve block on adapter plate- Caution: Control line must be clipped into the lug providedfor that purpose (see illustration) to ensure a correct lockingwith the adapter plate.- Check valve block for correct seat and close the lockinglever108
