• For INSTRUMENT Cycle (With Instrument Wash Option)
1. Cold water from building supply fills wash reservoir, enzymatic detergent is injected in chamber and water
from wash reservoir is sent to chamber (low speed).
2. Phase solution is recirculated on load alternately through traveler spray arms and rotary spray arm
assemblies (high speed).
3. Chamber heats phase solution and maintains solution temperature for guaranteed preprogrammed period of
time.
NOTE: Recirculation countdown begins when temperature is reached (factory-setting).
4. Meanwhile, hot water from building supply fills wash reservoir and detergent is injected in wash reservoir.
5. Chamber is drained upon completion.
6. Detergent-injected water is sent to chamber (low speed).
7. Phase solution is recirculated on load alternately through traveler spray arms and rack rotary spray arms
(high speed).
8. Chamber heats phase solution and maintains solution temperature for guaranteed preprogrammed period of
time.
NOTE: Recirculation countdown begins when temperature is reached (factory-setting).
9. Meanwhile, hot water or pure water from building supply fills wash or thermal reservoir in preparation for
Rinse phase.
10. Chamber is drained upon completion.
11. Fresh water is sent to chamber (low speed).
12. Rinse phase water is recirculated on load alternately through traveler spray arms and rack rotary spray arms
for preprogrammed period of time (high speed).
13. Chamber is drained upon completion.
14. Wash phase is followed by a Thermal Rinse phase (see Section 5.17, Thermal Rinse Phase).
