MAINTENANCE

BEFORE EACH USE, CHECK
THE DELIVERY: Start the delivery and check that there are no anomalies.
N2O BLOCK: Set a flow rate of 8 l/min with 50% N2O concentration, close the oxygen cylinder
(simulating a finished cylinder situation) and make sure that after a few seconds, the N2O supply is
completely blocked; if only N2O is delivered, do not use the device and contact technical support.
FLUSH BUTTON: Set up a supply with 50% concentration, check that the nitrous oxide supply is
interrupted and the oxygen flow is at maximum.
EVERY WEEK
CHECK FOR LEAKS:
- Open the valves of the Oxygen and Nitrous Oxide cylinders and note the values indicated by the
pressure gauges. Close cylinder valves. Wait ~ 5 minutes and measure the new values indicated by the
gauges. If the values coincide, the device does not leak.
- Disconnect the delivery tube from the mask, deliver approx. 5 l/min O2, close the tube with one
hand, check that the anaesthesia bag is inflated and that there are no leaks (e.g. tube cut, punctured
balloon).
Interrupt the flow.

ROUTINE MAINTENANCE - CLEANING

The DEVICE must be cleaned using clean gloves in a clean environment.
Use a disinfectant that is compatible with plastics (avoid cream products).
Do not spray the disinfectant directly onto the component to be cleaned, but onto a cloth.
Use disinfectants in the dilution indicated by the manufacturer.
The cleaning processes for individual components are described in the enclosed cleaning manual (e.g.
circuits, masks, reducers, etc.)

ROUTINE MAINTENANCE - CYLINDER REPLACEMENT

Cylinders must be replaced with extreme caution (see 5.5 CYLINDERS).
Procedure:
1. Slowly close the valves (turn CLOCKWISE).
2. If the system is under pressure, relieve the pressure to make it easier to remove the reducers.
3. Store the reducers in a sheltered, clean place.
4. Install the reducers on the filled cylinders.
5. OPEN THE VALVES SLOWLY, A RAPID OPENING OF THE CYLINDER VALVE CAN CAUSE A
SUDDEN RISE IN TEMPERATURE INSIDE THE REDUCER, WHICH CAN LEAD TO DAMAGE
AND BREAKAGE.
Refilling, inspection and periodic testing of cylinders must be carried out by
specialised companies in accordance with the directives in force in the country of
use.
