6.1.2 Setup for units 1730 & any unit with serial number prior to
2003000
Proper adjustment of the chamber pitch is one of the most
important things you can do for the sterilizer. Proper chamber
pitch insures that among other things the sterilizer will have the
proper amount of water in the chamber at the beginning of each
cycle. Insufficient water in the chamber at the beginning of the
cycle will generate a LOW WATER message at some point
during the cycle when the water level becomes to low. If on the
other hand there is too much water in the chamber this will extend
the heating portion of the cycle. In cases where the heating
portion of the cycle is extended for more than 50 minutes (80
minutes for a 3850/3870) the sterilizer will abort the cycle and
display a LOW HEAT message. Please follow these setup steps:
♦ Make sure the counter is level and sturdy (3)
♦ Make sure all the feet are on the autoclave and none have
been lost.
♦ Make sure the feet are free to move in and out (2)
♦ Position the autoclave on the counter
♦ Fill the reservoir with distilled water (see sec 6.5)
♦ The chamber should be empty of any instruments, trays or
leftover water.
♦ The autoclave should be turned off
♦ The chamber pitch now needs to be adjusted
♦ Measure to the proper amount of distilled water for the
appropriate model unit as listed below (the tolerances on
these amounts are +2 oz. and –0 oz)
1730 2340/2540 3545 3850 3870
10 oz 300 ml 12 oz 350 ml 14 oz 400 ml 20 oz 600 ml 24 oz 750 ml
♦ Pour the proper amount of water into the chamber through
the front door of the unit (4)
♦ This water should cover the bottom of the chamber to within
+/- ½ inch of the groove in the front. (1)
♦ If necessary adjust the front leveling feet so that the water
lays in the chamber correctly. (2)
♦ Once the chamber pitch adjustment is completed, empty the
water from the chamber and check if the automatic filling is
set correctly. See sec 6.2.3
