IM
M2 G4 Cycle Description Chart
The P3 and P4 disinfection temperature reflects the minimum guaranteed temperature
at any time during disinfection anywhere in the wash chamber. However, the disinfection
temperature is set to be around 93°C, with an upper switch point of the heater at 94°C
and a lower switch point of 92°C.
The HYDRIM M2 G4 incorporates a unique design where the air from the dryer motor
is pushed through the wash arms. The wash arms turn during the second high-speed
drying phase. This unique feature allows the HYDRIM M2 G4 to eliminate the risk of
water drops falling onto the dried instruments during unloading.
The disinfection time of P4 can be increased by 1 minute incremental intervals from 1 to
5 minutes. The minimum disinfection time is 1 minute with a minimum A
0
value of 3500.
The minimum A
0
value for disinfection time of 5 minutes is 6000. The final rinse time has
to be set and validated by a technician after installation in the office.
NOTE: ISO 15883-1 describes the time-temperature relationships for moist heat disinfection as follows:
“For a moist heat disinfection process, a particular time at a particular temperature can be expected to have
a predictable lethal effect against a standardized population of organisms. Definition of moist heat disinfection
process may be achieved by means of the A
0
method, which uses knowledge of the lethality of the particular
process at different temperatures to assess the overall lethality of the cycle and express this as the equivalent
exposure time to a specified temperature.”
* This is not a wash cycle. Always run a wash cycle following the rinse & hold cycle.
** Cycle times depend on the temperature and pressure of incoming water.
