GENERAL PRECAUTIONS & WARNINGS:
HEED is shipped empty. Fill prior to use.
No special training or SCUBA certification necessary for using HEED above ground or at shallow depths.
Never overfill the HEED system above 3000 psi, the air pressure stamped on the cylinder. ONLY use
purified, dry compressed breathing air when filling HEED.
DO NOT fill or use HEED if it has been exposed to extreme heat exceeding 250ºF, or open flame. Instead,
discharge the cylinder completely and return it to an Authorized dealer or the manufacturer for inspection and
possible hydrostatic testing.

attach First Stage to Second Stage Regulator Body.
Pressure Indicator
- Dial Gauge has an easy to read, color
coated display for at-a-glance pressure check in psi and bar.
Check Valve Refill Port
- Refillable from an Air Compressor or
SCUBA cylinder.
Mouthpiece
– High quality silicone mouthpiece.
Purge Button

mouthpiece.
On/Off Valve
- Twist valve to turn the air supply on and off.
3000 PSI Aluminum Tank
