HEED 3 - Refilling
The HEED 3 is a refillable fully self contained breathing device. The included Dial Gauge displays an accurate pressure reading in increments of 200 psi. Store the HEED 3 at full pressure and refill it only if you use it. The always-on regulator is ready to deliver life-saving air in an underwater emergency or toxic air environment.
Refilling is about as difficult as refilling a bike tire. There are 4 typical methods for refilling a HEED 3.
|Refilling from SCUBA Tank|
|The HEED 3 can be filled using an optional SCUBA tank refill adapter attached to a filled 3000 psi SCUBA tank.|
|Attach the 910S Tank Refill Adapter to your
|Place the refill adapter onto a filled SCUBA Tank. Slowly open the tank valve to allow the pressure to equalize, filling your HEED 3.|
|Refilling from a Hand Pump|
|In extreme circumstances where a SCUBA tank or powered air compressor may not be practical, a high pressure hand pump may be used to fill the HEED 3.|
|Attach the HEED 3 to the pump yoke.|
|Like inflating a bike tire, fully charge the HEED 3 to 3000 psi for maximum air capacity.*|
|Refilling at a Local Dive Shop|
|The HEED 3 can be filled at most local SCUBA Diving Shops who are Spare Air Dealers using the optional air compressor refill adapter.|
|Attach the 920C Air Compressor Refill Adapter to your
|Attach the compressor whip to the refill adapter. Release air into the Heed 3 to 3000 psi.|
|Refilling from a personal Breathing Air Compressor|
|If you have several HEED 3s to refill on a regular basis, a Nuvair Breathing Air Compressor may be your best option. Available in both Gas and Electric models.|
|Attach the HEED 3 to the 920C Air Compressor Refill Adapter.|
|Connect the adapter to the air compressor yoke and turn the compressor on, filling the unit to 3000 psi. (Electric Model shown)|
Note: if the unit is completely emptied of air in any underwater conditions, refer to the manual regarding proper servicing before refilling your HEED 3.
* Pressuring the HEED 3 to 3000 PSI using the hand pump is a strenuous, time consuming process.
