7.1.1. BEFORE USE

Visual inspection before use:
• Check the combination valve for damage (incl. label and marking). If it shows signs of external
damages, remove the product from service and suitably identify its status.
• Visually check the combination valve for contamination. If needed, apply the cleaning
EN
procedure according to chapter 9.
• Check if pressure is indicated on the content indicator of Manómetro Digital Display. If content
indicator of Manómetro Digital Display enters red zone, return the medical package (cylinder
with valve) for its refi lling.
Leak-tight and functional test before use:
• Open slowly the combination shut-off valve by turning slowly the combination control knob
"shut-off valve & fl ow selector" in anticlockwise direction to ON position.
• By listening check for a leakage (the leakage would be heard as characteristic hiss of fl owing
gas).
• Check that there is a gas fl ow at each "fl ow selector" set position in both anticlockwise and
clockwise turning direction (for instance by sound or checking presence of bubbles in a
humidifi er)..
• Turn off at the shut-off valve by turning the combination control knob "shut-off valve & fl ow
selector" in a clockwise direction to OFF position. Do not use excessive force (Maximum
recommended closing torque is 3 Nm).
• For combination valves fi tted with pressure outlet, ensure it is in working condition by
connecting and disconnecting quick-coupler probe.
If any leakage is detected, apply the procedure described in Chapter 7.1.3. and return the
valve for service.
Sudden opening could result in a danger of fi re or explosion arising from oxygen pressure
shocks.
7.1.2. USE OF COMBINATION VALVE
7.1.2.1. Use of combination valve fl ow outlet and setting of fl ow
• Ensure that the accessory is connected to the fl ow outlet.
• Open slowly the combination control knob "shut-off valve & fl ow selector" in anticlockwise
direction to ON position.
• Set the combination control knob "shut-off valve & fl ow selector" on one required fl ow rate.
Before connecting any accessory to the fl ow outlet make sure that the patient is not con-
nected.
Sudden opening could result in a danger of fi re or explosion arising from oxygen pressure
shocks.
Always ensure that the combination control knob "shut-o valve & fl ow selector" has been
engaged and not placed between two settings otherwise the fl ow control head will not deliver
correct fl ow of medical gas.
On fl ow control head, each valve is provided with so-called "end stop" located downstream
the maximum fl ow position. Do not try to apply excessive force on the combination control
knob "shut-o valve & fl ow selector" when it stops on the maximum fl ow position during an-
ticlockwise rotation.
Medical gas fl ow rate must be prescribed by a doctor.
