08 EN. Domistar, Hospistar, Neostar, PF4 - High Pressure regulators. Instruction for Use.
→ Pin index connection
• Position the pin-index over the cylinder valve with the pin(s) on the pressure
regulator pointing towards the cylinder valve connector holes on the cylinder
valve.
• Press the regulator inlet connection pins into the cylinder valve connector holes
- do not use force, other wise the pins or holes may be damaged.
• Tighten the screw on the regulator onto the cylinder valve connector via the
T-bar handle.
• Do not use tools.
Position the equipment so that the regulator user outlets point away from
personnel or patient.
Fitting the regulator with too high a torque to the cylinder valve may result in
damage.
During fitting to the cylinder valve, do not apply torque/load to any other
parts of the product.
→ Leakage check before use
• For regulators fitted with a flow-metering device, set the flow control knob on
the "ZERO" position - Ensure the flow control knob engages correctly.
• Open the cylinder valve slowly by turning the hand wheel in anticlockwise
direction approx 1 to 1½ turns.
Sudden opening of the cylinder valve could result in a danger of fire or explo-
sion arising from oxygen pressure shocks. Insufficient opening of the cylinder
valve could reduce actual flow delivered.
• Visually check possible leakages:
– regulator inlet connection to cylinder valve,
– pressure relief valve vent hole(s),
– pressure gauge to main body,
– flowmeter (if any).
