Refilling from Diving Cylinder

Spare Air is easily refilled from your own SCUBA tank in about 1 minute. Simply attach the adaptor that is included in every Spare Air package to your own SCUBA tank. There is no need to make a separate trip to the dive store to get Spare Air refilled.


Remove the protective plastic cap from the check valve located next to the Pressure Indicator. Remember to replace the cap after filling to protect the check valve from dust and dirt.


Gently attach the Yoke Adapter to your Spare Air by screwing the narrow end to the one-way check valve.
