Dial Gauge: Shows actual pressure in psi.
HEED 3 IS QUICK AND EASY TO REFILL!
HEED 3 is a refillable, fully self-contained breathing device. Models 175-001 and 300-001 come with an always-on regulator that is always ready to deliver live-saving air in an underwater emergency or toxic air environment. Model 175-003 with flexible hose requires a quick twist to turn on the air supply. Included with every HEED 3 is a Dial Gauge Pressure Indicator to give users the ability to quickly read the available air pressure.
HEED 3 should be stored full or with some positive pressure to prevent contaminants from entering the cylinder. Store in a clean, dry environment with optimum temperatures of 50-75ºF for best product performance. Avoid direct sunlight, automobile trunks or other areas subject to temperature extremes. Industry guidelines recommend replacing air in cylinders annually.
There are 4 easy methods for refilling HEED 3:
HEED 3 can be filled using the SCUBA tank refill adapter attached to a filled 3000 psi SCUBA tank.
Refilling at a
Local Dive Shop
The HEED 3 can be filled at any local SCUBA Diving Shops using the optional air compressor refill adapter.
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.
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.
