2.2.2.1 How to Change or Remove a Gas Canister
Push the lever located on the right of the canister. The canister will release.
(A slight twist on the canister may be required.) Remove the canister. See
Figure

The Nitrogen canister will need to be replaced after roughly 15 hours of use. The
Internal Standard canister will need to be replaced after 6 to 8 days of continuous
use. These numbers are guidelines and will vary.
WARNING
Do not refill canisters. Bodily injury may result. Canisters
are designed to be disposable and may fail if filling is
attempted.

Closing the front panel when the canisters are not
properly installed may damage the HAPSITE and/or
