/!\ Risk of bottle explosion. /
!\ First disconnect the mains plug.

This symptom is generally caused by a problem to the pressure regulator (fault or low temperature) or by a crack in the water bottle.

1. Stop using your device immediately and disconnect it from the grid.
2. Check the bottle in use for crack or any damage and, if the case, replace it with a new one.
3. Check the supplied air pressure: it shall be 4.5 bar minimum. 6 bar ideally.
4. If the device temperature is below 10°C (device too cold), wait for it to warm-up at ambient temperature and then reconnect to the power grid and switch it on again.
5. If the device temperature is over 10°C, or the problem recurs, definitively stop using it and contact EMS aftersales service.

Use a cleaning and disinfecting wipe (less than 35% alcohol) that complies with the standards applicable in the country.

EMS recommends the use of either - CleanWipes, IC-100 or PlastiSept Eco Wipes from ALPRO MEDICAL GmbH. - Micro-Kleen3™ Surface Disinfectant Wipes from Micro-Scientific. - CaviWipes1™ or Caviwipes™ 2.0 from Metrex Wipe and dry the device after disinfection and/or decontamination. Once a week use a damp micro fiber cloth with warm water to remove the residue build up that all wipes can leave on your AIRFLOW® Prophylaxis Master, cords and handpieces followed by a dry off with a soft non lint cloth

DO NOT use paper towels as these can be abrasive. Follow carefully the instructions provided by the wipes manufacturer. DO NOT use CaviWipes™ or Advantaclear wipes. They damage EMS products.
