28 Using the ventilator
5.8 Terminating ventilation
Important note!
Never empty the oxygen
cylinder completely. Re-
turn the cylinder for filling
while it still contains resid-
ual pressure. This prevents
entry of moist atmospheric
air that can cause
corrosion.
1. Check the oxygen supply on the gauge on the
pressure reducer gauge. If the pressure has
dropped to 50 bar or less, the cylinder should be
refilled or a reserve cylinder should be available in
order to ensure that the ventilator will be able to
function properly.
2. Close the valve of the oxygen cylinder.
3. Switch off MEDUMAT Standard. ON/OFF switch
must be kept pressed down for at least
2 seconds until the LEDs in the alarm panel light
up. This is a safety device to prevent the ventila-
tor from being switched off unintentionally.
