6.1.2 Setup for units 1730 and 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
too 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 3140 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 /-
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.
