2. Tools, Maintenance Schedules, Procedures and Testing
With cover on
Run cycle on unit to check for leakage or faulting.
Check unit's overall condition, including exhaust tube and bottle. Clean bottle, tighten fittings and check for
kinks in exhaust tube as appropriate.
With cover off
Check internal condition of unit, pay particular attention to corrosion.
Check water reservoir for contamination. If necessary, disconnect and remove reservoir, clean and rinse with
warm distilled water. Do not use any chemicals. Refit reservoir.
Check and clean probes if required.
Remove and fit new bacteriological filter. (where fitted)
Remove and fit new compressor filter. (where fitted)
Remove and fit new solenoid plunger and associated parts.
Remove and fit new check valve.
Remove cassette seal.
Clean process residue from all surfaces of cassette. (Use chlorine-free soap and scrub with cleaning pad
designed for Teflon.)
Check cassette for corrosion under seal seat.
Check cassette for damage. Note: pay particular attention to the rear hinge and rear wall of the base as
damage in this area may cause steam leakage even if a new seal is fitted.
Fit new cassette seal.
Note:
Check running function of pump, solenoid valve and compressor (control box buttons). Cassette must be
disconnected from probes.
Check pump flow in accordance with steam generator type and correct as required.
Check reference voltage as appropriate to board type and adjust as required. Not required on revision 7
units.
Switch off machine and switch on in calibration mode as appropriate to model.
Check steam generator thermocouple calibration as appropriate to board type.
Note: steam generator calibration is not required for software revision numbers XXXXR4XX onwards.
During the above cycle, check pipe work and fittings for steam leaks.

Control box, appropriate test cassette (with temperature and pressure port for 'S' units and
temperature port only for non 'S' units), appropriate reference meters (temperature and
pressure for 'S' units and temperature only for non 'S' units) and voltage meter are required for
this section.
For correct diagnostics and calibration of 'S' units, both temperature AND pressure meters
MUST be used.
