mesh patch from the box of O-rings in the recharge kit. Place the mesh in the center of the

protection cap. It is very important that the mesh is in the center of the protection cap and

covering the entire grille. Lower the sensor onto the protection cap making sure not to

disturb the mesh.

27. Push the protection cap firmly into place, making sure one of the four slots in the protection

cap fits over the small locking pin (highlighted right). If it is necessary to turn the protection

cap to fit over the locking pin, ensure you only turn it clockwise to avoid unscrewing the

cartridge.

28. Finally, screw the protection cap locking washer back into place in a clockwise motion, and

tighten finger tight.
