INTRODUCTION
WARNING!
∙As the sterilizer works with steam under pressure, some parts of it may become warm. You should therefore exercise the greatest caution whenever working on the sterilizer.
∙Hot steam may flow out of the sterilizer when the door is opened.
∙When handling materials and loading the sterilizer, bear in mind that the chamber and the area close to the chamber entrance is very warm.
∙Liquids must be sterilised in special programs intended for liquids. The sterilizer's liquid program is solely intended for the sterilisation of liquids in open vessels.
G e n e r a l
The VS-series consists of vertical sterilizers with preprogrammed sterilisation programs. The sterilizer works with steam produced in a chamber, fed with water from an external connection.

WARNING!
Remember the goods are hot after sterilising.
Never attempt to open the door until the pressure gauge has returned completely to zero.
4When the display shows F I N I S H, the green status lamp comes on and when the pressure gauge shows zero the process is completed.
5The display never shows F I N I S H and the green status lamp for process finished never comes on if the process is interrupted.
6As soon as the door is opened F I N I S H is no longer shown on the display, this provides information that if F I N I S H is not shown on the display, then the goods in the chamber may have been loaded by “someone else”, but not sterilised.
7If the red status lamp for an alarm is on after a sterilising process, the goods should be considered as unsterilised and must then be sterilised again.
When the door is opened F I N I S H is no longer displayed. The display now shows:
INSTRUMENT 1340C (last selected program)
IMPORTANT!

COMPONENT CHECK page 1
IMPORTANT!
Only use Teflon tape that is intended for sealing pipe couplings against steam pressure.
TIP!
Check whether steam is let out with an overpressure.
•Use soapy water on cold components
•Use a mirror on hot components
1. General
It is extremely important for safe functionality that all nipples are tightened so that air, which can jeopardize the sterilisation result, can not enter the chamber. If pipe couplings must be removed while performing checks, think about the following when assembling:
•Use ample Teflon tape, so that the tape partly forms a seal and partly seals the threads.
2. Chamber
The chamber walls are cleaned using a mild lime dissolving agent. Rinse well. Drain by closing the door, the bottom valve then opens automatically.
BOTTOM FILTER (ALSO SEE 23. SCREEN)
Lift out the filter. Clean
LEVEL GUARD (ALSO SEE 11. LEVEL GUARD)
Check that the rocker moves up and down easily.
3. Pipe/pipe couplings
Check:
Start a 134 °C program. Trouble shoot when the sterilizer is in “Sterilisation” mode.
Check whether steam is let out.
Action:
Check according to respective component checks. Also see 1. General.
Verification:
Check all pipes/pipe couplings again.
COMPONENT CHECK page 2
IMPORTANT!
All valves open in an energised state.
4. Solenoid valves
Pay attention to solenoid valves that hum! The noise may be a forewarning about the coil starting to overheat due to it not working in a closed iron circuit. This can occur when the moving core is influenced by the magnetic forces from the winding and dirt prevents the coil from reaching the end position. An air gap is then formed in the magnetic circuit, which lowers the inductance in the coil resulting in increased current.
MV-1
Is fitted in the bottom of the sterilizer and has the task of evacuating any remaining water in the sterilizer at the end of the process.
Check:
Check that both the plunger and the area it runs in are clean. Always change the O-ring that seals between the coil and housing after removing the coil. Activate MV-3 and fill the chamber. Activate MV-1 and MV4 (ejector). Check that the water runs out of the chamber again. Measure the voltage across the coil.
Action:
Clean and replace the plunger and O-ring. Replace the entire valve if necessary.
Verification:
Check that the water level in the chamber is maintained for a long period (about 15 minutes).
MV-2
Is fitted at the rear, top edge of the sterilizer. Takes care of pressure equalization after the post-vacuum phase by releasing air into the chamber. The valve is open when the sterilizer is in standby mode if the door is locked. It becomes de-energised as soon as the door is opened.
Check:
Check that both the plunger and the area it runs in are clean. Always change the O-ring that seals between the coil and housing after removing the coil. Activate MV-4 and MV-2 on the diagnostic menu. The pressure should not drop appreciably below atmospheric presssure. Measure the voltage across the coil.
Check for leakage: Dismantle BV-2. Activate MV-3 and the heater. No steam should come out of MV-2.
Action:
Clean and replace the plunger and O-ring. Replace the entire valve if necessary.
Verification:
Run a sterilisation program. Check for leakage acCOMPONENT CHECK
