MOUNTING INSTRUCTIONS:
Optional HEED 3 Holster is designed to attach to a modular style vest (MOLLE).
1.
Weave the 2 straps on the back of the modular holster through the webbing and snap into place.
NOTE: It is important that the operator be able to grip the regulator having sufficient clearance for a pull of at
least 6 inches.
2.
Place unit in Holster and attach flap securely over the regulator ensuring velcro is fully engaged.
NOTE: Mouthpiece can face left or right simply by switching mouthpiece cover and lanyard attachment to
either side of the holster.
3.
Attach Mouthpiece Cover.
PRE-USE CHECK:
1.
Check for obvious physical damage, broken or loose parts. Do not use if damaged.
2.
Visually check Dial Gauge for needle to be within green zone. Refill if necessary.
3.
Push Purge Button down and release. Purge Button should move up and down freely. To maintain full
pressure do not purge unnecessarily.
USING HEED:
1.
Pull D-ring on flap of Holster to open.
2.
Grab HEED regulator head and pull out of the Holster. This action will release the Mouthpiece Cover.
3.
Place HEED regulator int
o user’s mouth.
4.
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.
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 five year
service.
TRAVELING:
NOTE: When transporting product (not using) on commercial aircraft, cylinders must be VISIBLY empty and
removed from regulators.
1.
Purge until empty of air.
2.
Hold upside down and remove regulator from cylinder (regulator is attached hand tight) by turning counter-
clockwise. Leave o-ring, washer and exhaust discs on the regulator.
CAUTION: Do not force regulator on or off cylinder. Excessive force may damage threads. If
regulator does not remove easily, soak in a 1 to 1 vinegar & water solution for 3 hours to loosen any
corrosion.
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.
