Apollo 600 Operating Instructions

Prior to operation, the helmet, breathing tube, air supply hose, air entry ports and fittings must be thoroughly inspected and cleaned of all dust and debris. Also inspect the helmet suspension and adjust it if necessary (Adjustments see section 7.2).

The following steps have to be carried out before using the helmet:


(1) Air supply.
  • Start compressor.
  • Open service valve to pressurise the air supply line.

(2) Check air pressure.

Pressure must be set with the respirator connected.

(3) Check equipment.
  • Check all safety and breathing equipment used in conjunction with the respirator, as recommended by the manufacturer.

(4) Check air supply hose.
  • Check air supply hoses and connections for tightness and leaks.

(5) Put the respirator on.
  • Put the respirator on (keep it as upright as possible to prevent abrasive from falling inside.)
  • Position the knit cuff on the inner collar so that it fits comfortably. The collar assists in the prevention of dust entering the helmet. Do not allow shirt collars or other matter to interfere with the fit the cuff provides around the user’s neck.
  • Pull the cape down to fully extend it, and connect the straps on each side under the arms.
  • Put the belt and control valve on over the cape, buckle the belt around the waist and tighten it using the adjusting slide.

 

Adjustments

7.1  New Control Valve

 
Picture 1: New control valve

Clemco’s Air Control Valve allows the user to increase or decrease the volume of breathing air while wearing the supplied air respirator. To regulate it the knob on the side has to be turned.
If connected properly to the air supply the valve allows the breathing air to be adjusted to between  160l/min to 400l/min.

7.2  Adjustment of Suspension Assembly

Picture 2: Suspension

The following steps have to be carried out before using the helmet:


(1) Remove Cape.
  • Open buckle by pressing the small lever and pull out belt.
  • Remove cape.

(2) Adjust suspension.

Adjust suspension by rotating the knob to fit your head size. Turning clockwise à suspension gets narrower; turning anti-clockwise à suspension gets wider.

(3) Adjust chinstrap.

Adjust chinstrap to correct length by moving the buckle.

(4) Re-attach cape.

See 8.4 in Maintenance Instructions.

The suspension maintains a fixed distance between the head and the helmet. The suspension must be properly installed and adjusted to provide the protection and comfort for which the helmet is designed.
