Moulded letterbox weir / moulded open top weir
- Ensure the moulded stop ends that the weirs are to be fitted to are clean and dry. Blow dry with heat gun if damp
- Using a Stanley knife, cut all around the weir until the full weir capacity has been achieved
- With the specified fixings supplied, pin the stop end around the weir hole. Weir size will determine the quantity of fixings required
- Ensure Sharmans Fixing Caps are installed over all fixings prior to welding
- Push the weir through the hole in the stop end ready for welding
- Fully weld the flange of the weir to the stop end to complete the installation
- Allow the weir to cool before probe testing the weld
- Any un-welded areas will need to be re-welded and again probe tested once cool
