WARNING: Please follow instructions provided in the user manuals accompanying this product before replacing any components. General inspection of this equipment should be performed before and after each extended dive program, especially diaphragms, for wear, rips, tears or punctures. Replace diaphragm annually or more often as required.

CAUTION: During reassembly, the arrow on the diaphragm of the demand regulator assembly must be facing the regulator cover and the metal disc on the diaphragm must point to the hose connection (inlet). The diaphragm must be position so the tilt valve stem ball rides on the metal disc.
