Supply from an oxygen cylinder
Always use full tank (2400 psi)
• Attach pressure regulator for delivery pressure of 38
to 84 psi ( = 2.7 to 6.0 bar), nominal pressure 50 psi
to oxygen cylinder.
• Connect MicroVent with DISS high pressure hose to
oxygen regulator.
• Open valve slowly and completely.
