REFILLING HEED FROM FILL STATION USING #920C ADAPTER:
(Use a high-pressure, breathing air quality air compressor designed to fill air systems.)
WARNING: If the HEED Check Valve Refill Port or Refill Adapter threads are damaged or worn these parts will
require replacement. Continued use may cause injury.
CAUTION: DO NOT stand directly over HEED regulator while filling.
CAUTION: Ensure the regulator is firmly attached to the cylinder (hand tight, no tools required).
1. Unscrew black cap from Check Valve Refill Port.
2. Apply small amount of food grade silicone grease to Refill Port threads with your finger.
3. Screw Refill Adapter onto Refill Port until finger tight.
NOTE: DO NOT apply a wrench or otherwise overtighten.
4. Attach the yoke from the compressor to the Adapter.
NOTE: If line is pressurized over 3200 PSI, adjust the line pressure to 3200 PSI.
5. Turn the On/Off Knob counter-clockwise until it is completely open.
6. Turn the valve on your compressor ON.
7. Refill the cylinder to 3200 psi initially, after cooling down the pressure will be approximately 3000 psi.
Regulate the flow so that it takes approximately 45-60 seconds to fill the cylinder.
NOTE: Filling too fast can generate heat and will result in an incomplete fill after the cylinder cools.
NOTE: Fill cylinder slowly and DO NOT OVERFILL to protect the safety burst disc inside the regulator from
rupturing. If it ruptures, a new 3300 psi burst disc must be installed before unit can be filled.
8. When the cylinder is full, turn the On/Off Knob clockwise until it is completely closed.
9. Turn the compressor or fill station valve OFF.
10. Depress the 2nd Stage Purge Button until air flow can no longer be heard and the hose is depressurized.
11. Open bleed knob to release pressure in line. Remove Adapter from compressor yoke.
12. Remove Adapter from HEED and replace black cap on Refill Port.
13. Check the Pressure Indicator. If the tank is full, the Dial Gauge will read 3000 psi.

mouthpiece cover over mouthpiece.
4. Affix the included small velcro tab located on the metal ring to another web to help secure the holster.
PRE-USE CHECK:
1. Check for obvious physical damage, broken or loose parts. Do not use if damaged. Carefully inspect the hose
for any blisters or cuts.
2. Turn the system on by turning the On/Off Knob counter-clockwise until it is completely open.
3. Visually check Dial Gauge for needle to be within green zone. Refill if necessary.
4. Push Purge Button down and release 1 time only. Purge Button should move up and down freely. To
maintain full pressure do not purge unnecessarily.
USING HEED:
1. Grab HEED regulator head and pull until Hose is completely out of the Holster.This action will release the
Mouthpiece Cover.
2. Place HEED regulator into user’s mouth.
3. If the system is used underwater press purge button lightly or exhale sharply to expel water from the regulator
prior to inhalation.
CAUTION: Failure to purge the HEED regulator before inhaling will result in swallowing water.
5. Place Nose Clip (optional) on nose and adjust as needed.
6. Continue to inhale and exhale to a safe and normal rate of ascent. Take small, slow, steady breaths to
maximize the duration of air supply.
NOTE: The HEED utilizes a balanced regulator which means it will provide air in any orientation including the
regulator being upside down or sideways.
CAUTION: If HEED is used until completely empty underwater, it should be referred for Overhaul
Service.
5. When done using system, turn the On/Off Knob clockwise to turn off.
TRAVELING:
NOTE: When transporting product (not using) on commercial aircraft, cylinders must be VISIBLY empty and removed
from regulators.

3. Place HEED in a protective container (plastic bag or box) to keep unit clean and to secure loose parts.
4. Pack in your check or carry-on luggage.
5. When you reach your destination, reassemble (hand tight) and fill the cylinder. Lightly lubricate the tank o-ring
with a small amount of silicone grease –never use a hydrocarbon based oil. DO NOT force regulator onto
cylinder.
NOTE: Replace o-ring after product has been disassembled and reassembled 3 times, or o-ring shows signs
of wear or air leakage.
SERVICE INFORMATION:
•Ensure HEED is always pressurized whenever it is submerged to prevent water from entering system. If
HEED has been emptied of air underwater it should be referred for Overhaul Service.
•If a leak or damage is found at any point the unit should be referred for Overhaul Service.
•No matter how often the unit has been used, or even if the unit has not been used at all, the HEED requires
tank inspection and regulator overhaul every 5 years.
•Service intervals are from the Date of Manufacture (found on the cylinder neck –look for XX A XX
representing the month and year of manufacture).
•Service record for each serial number should be maintained by user and record the date of the Annual
Check and Overhauls as they are performed.
ANNUAL CHECK (performed by user):
1. Visually check Dial Gauge for needle to be within green zone. If it is not, perform a leak test to determine if
the HEED is actually leaking or if it just needs to be filled.
2. Look for obvious physical damage, such as broken or loose parts. Check openings of diaphragm cover for
presence of foreign objects or punctures of blue diaphragm. Check that all parts are clean and securely
attached.
3. Perform a leak test. HEED must be pressurized and needle within the green zone.
a. Completely submerge filled unit into a tub of water.
b. Shake the unit back and forth several times so that all trapped air is released.
c. Hold the unit still and watch for any leaks for 60 seconds (spend 20 seconds at each of the following:
mouthpiece opening, side ports, and tank o-ring areas).
NOTE: A leak is defined as a continuous bubble at a constant rate.
d. If leak is detected, refer unit for Overhaul Service.
4. If unit is filled at a Dive Shop they will require that the cylinder is visually inspected annually by them and
receives a fresh VIP sticker.
OVERHAUL & CYLINDER SERVICE (to be performed by repair facility / manufacturer):
1. Regulator Overhaul Service: Recommended for the HEED every 5 years when not used underwater or in a
training environment. Service includes: Overhaul of regulator, replacement of all worn parts, visual inspection
of cylinder and labor. Cylinder will receive a new VIP (visual inspection) sticker with the date marked.
2. DOT 3AL cylinder: Hydrostatic testing is required every five years. Any cylinder exposed to fire or heat in
excess of 350°F, or shows signs of corrosion, pitting or damage should be evaluated further. CE marked
cylinder - Refer to local country regulations for how often hydrostatic testing should occur.

UNITS USED IN TRAINING ENVIRONMENT:
1. HEED used frequently in a water environment or for training purposes will need extra care:
a. After each in-water use, rinse and soak pressurized HEED for at least 30 minutes in warm, fresh water.
b. Rigorously shake and/or utilize a steady stream of water to dislodge any debris (salt, mineral deposits,
sand, etc.).
c. Gently shake to drain water and wipe dry with a clean towel.
2. HEED Overhaul Service to be performed more regularly, approximately every three to six months.
NOTE: Use in chlorinated swimming pool water will accelerate the deterioration of most rubber
components and require more frequent service than in other typical conditions.
ROUTINE CARE & STORAGE:
1. For general cleaning, use a mild dish soap or Simple Green / biodegradable solution.
2. For sanitizing, use a commercially available regulator sanitizer available through a dive shop.
3. Keep the threads on both the Refill Port and Refill Adapter clean and lubricated. Use high-quality, non-
toxic, food grade silicone grease for best results.
NOTE: NEVER use a hydrocarbon based oil (i.e. household oil or motor oil), petroleum based substances to
clean or lubricate. Do not expose the regulator to aerosol spray, as some aerosol propellants attack or
degrade rubber and plastic.
4. Store HEED 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. Avoid storing where it may be
exposed to an electric motor which produces ozone. Prolonged exposure to extreme heat, ozone, chlorine
and ultraviolet rays can cause premature degradation of rubber parts and components.
NOTE: Industry guidelines recommend replacing air in cylinders annually.
