and unused. If the device is not run regularly per this recommendation there is a risk it will not perform to specification when removed from
storage.
1) Turn on the SAROS and run at any continuous flow setting until the battery is completely drained and the SAROS powers off.
2) Once the SAROS powers off, immediately connect to AC external power to begin re-charging the battery. You may either continue to run the
SAROS or leave it powered off during re-charge.
