All Models of KMDSI Helmets SIDE BLOCK / DEMAND REGULATOR • Check/cycle the Steady Flow Valve for properation, ensure smooth operation, and strong gas flow from the air train when turned 1/2 turn • Normally, divers never have to open the Valve more than 1/4 turn. • Demonstration

All Models of KMDSI Helmets SIDE BLOCK / DEMAND REGULATOR • Steady Flow Valve will rotate approximately 1 ¾ revolutions from closed to full open • With the air pressure adjusted to between 135150 psig o. b. , opening the Steady Flow Valve one -quarter rotation will provide a minimum of 6 acfm flow of gas • Reach inside the Helmet, to check for a strong flow of gas through the gas train

All Models of KMDSI Helmets SIDE BLOCK / DEMAND REGULATOR • Secure the gas supply, bleed down and remove the gas supply from the Inlet Adapter • With the emergency gas (EGS) Valve shut, attach a regulated gas supply (normally the EGS System), adjusted 135 -150 psig, to the EGS Valve on the Side Block and then slowly open the Emergency Valve

All Models of KMDSI Helmets SIDE BLOCK / DEMAND REGULATOR • Back out counterclockwise on the Regulator Adjustment Knob until a slight free flow develops, then turn in until the free flow stops • Depress the Purge Button and check for a strong purge then momentarily crack open the Steady Flow Valve and insure a strong surge of gas

All Models of KMDSI Helmets SIDE BLOCK / DEMAND REGULATOR • Check to ensure there is no gas escaping from the open umbilical adapter on the one- way Valve • If any leakage is found, the one way Valve should be overhauled or replaced
