RATBLOCKER
1. Once the manhole cover is removed, identify which outlet(s) requires a rat blocker and ensure they are free-flowing and clear of debris.
2. Offer the Hamelin Rat Blocker up to the outlet – if the manhole is particularly deep or hard to access then the optional installation pole (SKU RB/Pole) can be used, although this is not a requisite purchase.
3. If a tighter or looser fit is desired, use a pair of pliers to tweak the four adjustable corner tabs.
4. Then fully insert the rat blocker, ensuring the flap allows for flow in the correct direction – the top nut and bolt can be moved to allow for inlet installation if preferred.
5. For added piece of mind, a tether kit can be used to anchor the rat blocker to the side of the chamber, although this is optional.
6. Finally, test the installation by flushing a toilet upstream of the rat blocker to ensure free flow.

PREVENTAVENT
1, Locate all air bricks around the property and ensure you have the correct size Preventavent to cover the entire vent.
2, IF INSERTING WITH SCREWS:
Drill 4 holes in line with each corner of the Preventavent and insert a red wall plug, using 5.5mm screws, drill through the pre-drilled holes to secure the Preventavent against the vent.
3, IF APPLYING WITH ADHESIVE:
Using a strong adhesive suitable for exterior use, apply a bead to the back edge of the Preventavent, press against the airbrick vent and hold in place until set.
