The CO2 canister is marked with an orange visual warning system. When screwing the canister into the triggering mechanism take great care not to cross thread. Continue to screw the canister in until tight and no orange is visible, which will help ensure the canister will be fully pierced during activation. If the canister is not tightened enough it may not be fully pierced inducing slow or no inflation. Avoid using tools to over tighten.
These canisters are compatible with the AyrPS system and Ayrvest system; the canister is manufactured by Helite.
