5: Preparaon of the Pump Head
The pump head will mate with the Angled ange. Between the Angled ange and the pump head there is a o-ring to provide sealing.
Cauon: 8 holes with conical shaped cavies are cut the pump head. Each hole has a thread cut into the plasc.
Tighten thoroughly, but not over-ghten to prevent damage to this thread.
Cauon: When ghtening the nuts: Apply the hexagon tool to give counter pressure. Prevent the bolds from rotang when nuts get
ghtened. Rotang nuts will damage the treads in the plasc pump house and may cause leaks if Sikaex 291i seal is broken.
- Apply Sikaex 291i to each hole
- Make sure to provide Sikaex to the thread of all 8 bolds that screw in the pump head
- Do not use any other sealant than Sikaex 291i for this job.
Leaks will occur if this procedure is not performed perfectly!
- Place provide o-ring to Angled Flange
- Mate pump head to Angle Flange
- Apply washers and nut
