FUNCTIONAL DESCRIPTION
3.1
The Steam Generator
A built-in steam generator is installed to act as a standby if building steam is not
available for the sterilization process. See ―Switching to Steam Generator‖ section for
steam generator operation. The power consumption of the generator is 36 kW.
Water to the steam generator is supplied by a one-phase pump, from a water reservoir,
which is connected to a source of distilled or de-mineralized water. The electrical system
of the steam generator is located in a separate electric box.
The water level control system consists of three electrodes connected to the
GICAR
2DRLHG controller, which commands the operation of the water pump and servo
solenoid valve to switch OFF the heating current in case of lack of water or low water
level.
Use only distilled or mineral-free water for the operation of the generator!
Caution!
It is strictly forbidden to use soft water; this may results in corrosion of the
generator.
Warning!
Only a qualified electrician may perform the electrical connections!
The electrical units should not be placed near water sources.
When servicing the generator, disconnect the all electrical power supplies to the
unit. This is done by switching OFF the main power supply switch, or by un-
plugging the electrical power main supply cords.
It is important to achieve an electrical good grounding connection to the sheet
metal enclosure of the electric box and metal parts of the generator.
The earth installation at the customer’s site must be built in compliance with the
laws and regulations in force, and should meet international electrical safety
standards, and be certified by competent authorities.
