5 Maintenance

• Do not sterilize the components by any method other than autoclaving.
• The 

fi

 le holder and contrary electrode are extremely hot after autoclaving; do not touch them 

until they cool o

ff

 .

 Autoclaving and drying temperatures must never exceed 135°C (275°F).

 For sterilizing 

fi

 les, follow the manufacturer’s instructions.

Sterilization

Autoclave the components after use for each patient. 
Recommended temperature and time: 135°C (275°F), six minutes minimum in 
a sterilization pouch.

5.1.2 Wiping with Ethanol for Disinfection (Ethanol 70 vol% to 80 vol%)

Wipe the components with a piece of gauze that has been dampened with ethanol for 
disinfection (ethanol 70 vol% to 80 vol%) and wrung out thoroughly. 

5.4 Transport and Storage

Transport and storage environments:
Temperature:  -10°C to 70°C (14°F to 158°F)
Humidity: 10% to 85% (without condensatin)
Atmospheric Pressure: 70kPa to 106kPa

• Avoid frequent or continuous exposure to direct sunlight.

• If the equipment has not been used for a while, make sure it operates properly and safely before using it again. 

 Never wipe components with any solution other than ethanol for disinfection (ethanol 70 vol% to 

80 vol%). Other solutions could cause cracking and discoloration.

 Avoid spilling chemical solutions used for treatment on the any of the components. Wipe up 

any chemical spills immediately. These chemicals could damage, deform or discolor plastic and 
metal. Use extra caution to avoid spilling formalin cresol (FC) and sodium hypochlorite as they 
are quite strong.
