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.
General
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!
Consider the risk of burns when loading the sterilizer.
CAUTION!
Only sterilise items intended for sterilisation with steam and that can withstand at least 121 de­grees. Only use loading equipment espe­cially designed for the VS series. Each standard basket may be loaded with max. 12 kg of goods. To ensure optimal ergonomics use a lifting device when processing heavy loads.
CORRECT OPERATION, CHECKLIST
1 Placing items in the sterilising chamber. Only use
loading equipment especially designed for the VS series. Carefully check that nothing is caught
between the door and chamber. Place moisture -sensitive items and low-mass
items at the top of the chamber.
Place heavy items at the bottom of the sterilis-
ing chamber. Place dish-shaped items dish side down. Place empty containers (bottles, test tubes,
etc.) with their opening downwards.

4 When the display shows FINISH, the green status
lamp comes on and when the pressure gauge shows zero the process is completed.
5 The display never shows FINISH and the green
status lamp for process finished never comes on if the process is interrupted.
6 As soon as the door is opened FINISH is no
longer shown on the display, this provides infor­mation that if FINISH is not shown on the display, then the goods in the chamber may have been loaded by “someone else”, but not sterilised.
7 If 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 FINISH is no longer dis-
played. The display now shows:
INSTRUMENT 1340C (last selected program)
00.05.00_1340C
WARNING!
Remember the goods are hot after sterilising. Never attempt to open the door until the pressure gauge has re­turned completely to zero.
LIQUID STERILISATION
A special liquid program and a load sensor in the chamber are required to sterilise liquids. The liq­uid process is solely intended for liquid sterilisa­tion in open receptacles.
Bottles should be filled to max. 80 % of their vol- ume.
Place the load sensor in the largest container. When there is no space in the liquid for the load sensor, use a control receptacle where the load sensor can be placed. The volume of the liquid in the control receptacle should be as great or grea­ter than the liquid intended for sterilisation. Boiling point for the liquid in the control vessel must be the same as for the liquid to be sterilised.
Use a receptacle with the smallest possible vol- ume for the fastest processing.
OPERATION, CHECK
IMPORTANT!
If the process must be cancelled for one reason or another press the STOP button; the red status lamp will come on and an audio signal with sound. Now press the RESET button and wait for the pressure gauge to drop to zero. When the red status lamp indicat­ing an alarm has gone out, press the RESET button. Open the door.
IMPORTANT!
When a process is interrupted, there is a risk of steam streaming out of the chamber when the door is opened.
INTERRUPTED PROCESS
If the sterilizer stops the process: 1 Press the RESET button; the audio signal stops. 2 Wait until the pressure indication shows zero. 3 When the red status lamp has gone out: 4 Press the RESET button; the alarm text is no
longer displayed
If a process in progress has to be interrupted: 1 Press the STOP button; the text PROCESS
STOPPED is shown on the display. The audio sig-
nal sounds and the red status light comes on.
2 Press the RESET button; the audio signal stops. 3 Wait until the pressure indication shows zero. 4 When the red status lamp has gone out, press the
RESET button; the alarm text is no longer dis­played.

1. General
IMPORTANT!
Only use Teflon tape that is in­tended for sealing pipe couplings against steam pressure.
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.
TIP!
Check whether steam is let out with an overpressure.
Use soapy water on cold com­ponents
Use a mirror on hot compo­nents
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 ac-
