1. UNIT OVERVIEW
Introduction
This service manual was created to act as reference for the service and repair of the STATCLAVE G4. If you
have a question about the unit you are repairing, please do not hesitate to contact your local SciCan
representative for information.
Principles of operation
The STATCLAVE G4 is a dynamic air removal (pre-vacuum) table-top steam sterilizer that uses steam to
sterilize wrapped and unwrapped instrument loads typically used in dental and medical offices. It has six
validated sterilization cycles with optimized drying for fast, effective instrument processing. An additional
custom cycle can be configured using one of three temperature settings but this cycle must be validated by
the user.
Steps in a typical cycle
After pressing the START button to activate a cycle...
1.
The band heaters turn on to warm the chamber to its operating temperature.
2.
Water from the clean water reservoir is pumped to the boiler to create steam.
3.
The vacuum system uses a Venturi device instead of a vacuum pump to remove air from the chamber
as it fills with steam to ensure efficient air removal and steam penetration into the load.
4.
Water from the clean water reservoir is pumped to the boiler to saturate the chamber with steam
and bring the unit to sterilizing temperature.
5.
Steam sterilization is achieved by exposing products to direct saturated steam contact at the required
temperature and pressure for the specified time.
6.
When it has completed the sterilization phase, the unit vents steam from the chamber to the
condenser and into the exhaust bottle.
7.
The Venturi-based vacuum system activates to pull any remaining steam and moist air from the
chamber.
8.
Filtered air is drawn into the chamber to dry the load and the band heaters are activated to speed
drying.
How does STATCLAVE G4 use a Venturi device to create a vacuum?
In the STATCLAVE G4, a water pump moves water through the constricted channel of a Venturi device. As the
water goes through this constriction, from a large pipe to a small pipe, it creates an area of low pressure. A
third tube connects to this constriction through which the low pressure draws a vacuum.
