Automatic cleaning (including thermal disinfection)
Note: The washing machine used must comply with the NF EN ISO 15883-1.
1. Disassemble devices (Refer to PREPARATION FOR CLEANING & REASSEMBLY)
2. Rinse components under warm tap water prior to placing in washer.
3. Position the device so as to prevent contact between the elements.
4. Select the cycle for instruments and perform the proper programming for the following cycle:
Phases
Pre-wash 1
Enzyme wash
Wash 1
Rinse 1
Thermal rinse**
Step 3: Disinfection
The MAYFIELD 2 Base Unit must be thoroughly cleaned after each use. Where possible, keep the soiled areas moist until the
disinfection process can be initiated.
IMPORTANT: If the product has been exposed to persistent pathogens1, do not apply gluteraldehyde, alcohol or formalin
to the device until the decontamination process is complete. After decontamination, normal cleaning processes can be
employed (see Decontamination section).
Disinfection of device components following normal usage may be achieved using the following methods:
Method 1: Thermal Rinse
• A Thermal Disinfection rinse may be added after the first rinse cycle as indicated in Table 1.
Method 2: Chemical
• Prepare a fresh solution for general disinfection (See below guidelines for bleach solution).
• With the device disassembled, place parts in a shallow pan and add enough general disinfection solution to
cover the device completely.
• Allow the parts to soak for 15 minutes.
• Rinse thoroughly with clean water.
For General Disinfection
Verify concentration of base hypochlorite is 4.5% or more
Mix 1/2 unit of bleach into 10 units of water
Table 2 Hypochlorite Bleach Mixing Guidelines
* No limit on tap water temperature
** Optional phase for disinfection of components – minimum water temperature as indicated or per washer manufacturer specifications for the thermal rinse cycle
1. Persistent pathogens are resistant to deactivation by normal disinfection procedures and may require more aggressive treatment to achieve disinfection. See guidelines in Decontamination
for recommended procedures.
