Use Of Product; Before Use - GCE MediVitop Mode D'emploi

The flow outlet "G" is equipped with hose fitting (hose nipple) or a threaded type (for acces-
sories to be connected via threaded connection).
Movement of the flow outlet 'G' is normal due to the method of fixing in the main body. It doesn't
indicate a faulty flow outlet.
H – PRESSURE OUTLET - QUICK COUPLER OR PURGE VALVE (OPTION)
The pressure outlet is the outlet direct from the low-pressure part of the valve and it is fitted with
a specific quick connector or purge valve.
In the use of the valve with quick connector also called "quick coupler" (see appendix Nr 2) the
user can connect another piece of equipment to quick coupler with a gas specific male probe
EN
– quick-coupler probe. Its disconnection means self-sealing of the quick connector. This outlet
is for supplying gas at a controlled pressure to power medical devices, for instance medical
ventilator.
The valve without the quick coupler is provided with purge valve that is used to vent residual
pressure in the low-pressure part of the valve.
I - PRESSURE RELIEVE VALVE OF LOW PRESSURE PART
Pressure relieve valve secures the low pressure part of combination valve and connected medi-
cal devices against over-pressure. If the gas pressure is decreased enough after the pressure
relieve valve activation, it will closes itself.
J - EXCESS FLOW DEVICE OR DIP TUBE (OPTION)
Excess flow device ensures safe ventilation of gas from gas cylinder in case the combination
valve is broken above inlet stem (e.g. cylinder fall). Dip tube does not have such function. Ex-
cess flow device and dip tube are to avoid contamination from cylinder entering the combina-
tion valve.
K - BED HANGER OR HUMIDIFIER HOLDER (OPTION)
Bed hanger enables to hang medical gas package on hospital bed. Humidifier holder enables
to connect humidifier to the combi valve.
PRESSURE RELIEVE DEVICE OF HIGH PRESSURE PART - BURSTING DISC (OPTION)
The high pressure relieve device is intended to protect the cylinder and high pressure part of
combination valve against damage caused by increased cylinder pressure. If the pressure re-
lieve device has been activated, it will not reseal and the combination valve must be taken out
of service for repair (see Chapter 9).
Note: Colour of the product (especially guard and combination control knob) does not have
to match the gas colour coding.

6.1. OPERATIONS PERFORMED BY USER

6.1.1. 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 proce-
•
dure according to chapter 8.
Check that the cylinder gas pressure indicator indicates sufficient pressure. If it indicates in
•
the red zone, return the cylinder with combination valve back for filling.
LEAK-TIGHT AND FUNCTIONAL TEST BEFORE USE:
Open slowly the combination shut-off valve by turning slowly the combination control knob
•
"shut-off valve & flow selector" in anticlockwise direction to ON position.
By listening check for leakage (leakage would be heard as characteristic hiss of flowing gas).
