On a regular basis (in line with hospital procedures for
infection control), and at least every six months, the patient
block (1) must be removed, cleaned and sterilised.
CAUTION: After cleaning and sterilisation, and/or repair, the
patient block assembly must be refitted to the original control
unit (see operation 4 in 6.2.7.2, below).

outlets (2) on the outer face of the patient block assembly.
2. Note the different diameters for correct refitment.

4. Carefully detach the assembly (1) from the control unit.
Note that resistance will be felt until the metal tubes (4)
and probe (5) disengage. Do not disassemble the patient
block.
