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.

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:

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.

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-
COMPONENT CHECK
page 3
cording to Check and that pressure equalization takes
place at the end of the program.
MV-3
Is fitted directly on the inlet. Loads the chamber with
water at the start of the process.
Check the opening function:
Activate MV-3 in the diagnostic menu; water should
then flow into the chamber.
Check the closing function:
In standby mode, check that the water level in the
chamber does not rise once the valve to the chamber
has been closed.
Action:
Clean and replace the plunger and O-ring. Replace
the entire valve if necessary.
Verification:
Run a sterilisation program. Check that no water enters the chamber after the process has ended and the
door is open.
IMPORTANT!
Minor steam leakage can be due
to a leaking gasket and has nothing to do with the MV-5 function
MV-4
Opens the water flow to the ejector to produce a vacuum
Check:
Check that water does not run out of the drain hose in
standby mode
Action:
Clean and replace the plunger and O-ring. Replace
the entire valve if necessary.
Verification:
Run a process and check again that water does not
run out of the drain hose in standby mode.
MV-5
Pressurises the door gasket before a program.
Check:
During the process, check that the door seals against
steam.
Action:
Clean and replace the plunger and O-ring. Replace
the entire valve if necessary.
Verification:
Check the door for steam leakage.
MV-6
Vents the chamber while the program is running.
Opens at the given time interval. Also simplifies eva-
COMPONENT CHECK
page 4
evacuation of the chamber pressure after sterilisation
is completed.
Check:
Build up a pressure in the chamber. Open MV-6. The
chamber pressure should drop. Check that the chamber pressure is maintained when MV-6 is closed. Pipes on the outlet side should be cooler than on the
pressurised side.
Action:
Clean and replace the plunger and O-ring. Replace
the entire valve if necessary.
Verification:
Run a program. Now verify according to Check, see
above.
MV-8
Evacuates the door gasket pressure after the completed process.
IMPORTANT!
A symptom of poor opening function in the valve is difficult door
opening.
TIP!
Ensure the heater is de-energised
before you measure the resistance.
Check:
Close and lock the door. Open MV-5 and open MV-8.
Water should flow out of the drain.
Action:
Clean and replace the plunger and O-ring. Replace
the entire valve if necessary.
Verification:
Run a process. The door should be easy to unlock after the completed process.
5. Heater
Is fitted in the bottom of the chamber and has the task
of heating the water dosed for the process.
Check:
Activate the heater. Measure with a clamp-on ammeter, this should show about 8 A/coil. The heater output
is 2000 W x3 coils, which gives a resistance of about
27 Ω/coil. Check the resistance.
Action:
Replace the heater with incorrect resistance.
If the clamp-on ammeter shows 0 A, and the relay and
circuit board are OK. Replace the heater.
Verification:
Verify by measuring the resistance.
COMPONENT CHECK
page 5
IMPORTANT!
Note that if overheating protection
trips due to a temperature outside
of the working range (0 - 300 °C),
the sterilizer must cool for a period so that the resetting button
shall remain pressed in. Wait until
the sterilizer is within the working
range again.
Note that it may also require a
great deal of force to press in the
overheating protection.
6. Relay
Is fitted in the distribution box. Its task is to connect
the heater to the power supply.
Check:
Activate the heater, measure the coil on the relay using a voltmeter. The coil is across A1-A2. Measure the
voltage on the outgoing connection 2 - 4 - 6
7. Overheating protection, resetting
Protects the heater against overheating, the protection
trips at approx. 300 °C. Requires manual resetting.
The sensor is positioned on the heater coil. The resetting button is positioned on the protection. A symptom
that the overheating protection has tripped is the timeout alarm, heating error.
Possible causes:
• That the sterilizer has been transported in tem-
peratures below freezing.
• That a fault has occurred in the temperature regu-
lation of the heater.
• That leakage results in the water being consumed
during the process.
The unit should always be de-energised when resetting.
CAUTION!
Check that the overheating protection sensor is fitted correctly on
the heater. Otherwise the sensor
has no function.
Check:
Check that the manual resetting button is pressed in.
Measure the voltage on the incoming and outgoing
pins on the protection. Voltage on the incoming but
not on the outgoing, means that the protection has
tripped or is faulty.
Action:
Replace the overheating protection. Make sure that
the sensor is correctly fitted on the heater. Also see
daily maintenance
Verification:
Check that the sterilizer display is lit.

purpose of preventing return flow through MV-3
Check:
Fill the chamber with an open door by opening MV-3.
Shut the main tap and let MV-3 remain energised and
open MV-4. Check whether water is running out from
the drain or that the level in the chamber drops over a
long period of time, at least 15 minutes.
Action:
Replace BV-1.
Verification:
As Check, see above.
9. Non return valve
BV-2
Is fitted between the air filter and MV-2. Its task is to
prevent steam, with a fault on MV-2 being forced through the filter.
Check:
Close and lock the door. Remove the air filter. Build
up a pressure; open MV5 and MV1, close MV1, activate the heater, open MV2. The pressure should rise
to 1 bar according to the front pressure gauge. Check
that no steam comes out of the air filter holder.
Action:
Replace BV-2. Check that the air filter is not wet.
Verification:
As Check, see above.
10. Non return valve
BV-3
Is fitted after MV-1 and has the task of preventing water from the ejector returning up into the chamber

6. The solenoid valve MV-1 is used to empty the water from the chamber.
7. The steam pressure is released via MV1 and MV6
8. The water pressure powers an ejector, which creates an underpressure in order to lowe r the
chamber pressure below atmospheric pressure.
MV4 releases the water pressure on the ejector.

13. The heater heats the water and the pressure rises.
14. The steam pressure is monitored by the pressure
sensor which, via a PID -regulator, controls the
heater.
15. The load sensor monitors the temperature of the
liquid to be sterilised. The load sensor temper ature determines when the sterilizer switches to
sterilisation.
16. The solenoid valve MV-1 is used to empty the water from the chamber.
17. The steam pressure is released via MV1 and MV6
through ramping to prevent decoction.
18. When the liquid reaches a temperature below
95°C (controlled by the load sensor) MV-8 releases the gasket pressure and the door can be
opened. The process is complete.
PRE-TREATMENT
The purpose of pre-treatment is to remove air from the
chamber and from the goods. Air prevents the requisite contact between the steam and micro -organisms
to be killed.
Pre-treatment consists of steam injection and evacuation pulses in different processes depending on the
program selected. In addition, the humidification essential to killing mainly takes place during the pretreatment stage.
Pre-treatment process:
• Blow through (1)
MV-1 opens, the chamber is filled with water and
the heater then heats the water. MV-6 opens during the preset time.
• Pressure increases (2)
MV-6 closes and the heater heats. The pressure
rises to a preset level. The sterilisation pressure
should be reached during the final increase in
pressure. Sterilisation begins when the sterilisation pressure is reached.
ADVANCED TROUBLE SHOOTING, PROCESS DESCRIPTION
STERILISATION
Sterilisation takes place by maintaining the saturated
steam's relation (boiling point at a specific pressure).
The sterilisation phase is in progress during a pre programmed number of minutes at the preselected
temperature/pressure.
Sterilisation process:
• MV-6 opens during the preset time intervals.
• The pressure is controlled by means of the heater,
which heats as required.
POST TREATMENT
The purpose of post treatment is to reduce the moisture content in the goods. During post treatment the
pressure drops to atmospheric pressure or lower –
depending on the selected program. Post treatment is
completed by air being drawn in until the chamber is
at atmospheric pressure.
Post treatment process:
• MV-1 opens and releases the remaining water.
• MV-4 opens and the ejector starts.
• MV-6 opens after an additional few of minutes.
• When the right vacuum is reached (800 mBar)
time metering starts.
• When the time elapses MV-1, MV-4 and MV-6
close. MV-2 opens and air is drawn in and the
pressure rises towards atmos pheric pressure.
MV-8 opens and the door gasket pressure is released. The process is finished.

• Pressure increases
MV-6 closes and the heater heats. The pressure
rises to a preset level just above the sterilisation
pressure to accelerate the heating of the liquid.
When the load sensor temperature approaches
the sterilisation temperature, the steam pressure
drops to the sterilisation pressure. Sterilisation
starts.

The purpose of post treatment is to lower the temperature of the liquid below boiling point at atmospheric pressure.
Post treatment process:
• MV-4 opens and the ejector starts.
• MV-1 opens at the preset time intervals to ensure
a slow pressure decrease and prevent decoction
of the liquid. The remainin g process water is released in connection with ramping.
• When atmospheric pressure is reached and the
temperature of the liquid (controlled by the load
sensor) is below 95°C, MV-1 and MV-4 close.
MV-2 opens and the atmosphere in the chamber
and the atmosph ere is the room are kept at the
same level. MV-8 opens and the door gasket

INSTALLATION
CAUTION!
Installation must be carried by
technicians with documented
experience.
WARNING!
Make sure that the area where the
sterilizer is to be located can
withstand a load of at least 250 kg.
INTERNAL TRANSPORT
The easiest method to move the sterilizer is using a
pallet truck or a barrow with a minimum lifting limit of
120 kg.
UNPACKING
Check that the packaging is intact.
Check that the supplied goods correspond with the
order.
Check that the sterilizer is free from defects.
Transport damage must be reported immediately to the
carrier.
Setup
PREPARATIONS
Setup ought to be carried out by technicians with
documented experience.
The sterilizer must be located indoors with a maximum
ambient temperature of 35 °C and a relative, no
condensing, humidity of maximum 95 %.
CAUTION!
Ambient temperature, max 35 °C.
Ambient humidity, max 95 %.
PLACEMENT
The sterilizer is a floor model and must stand free, it
must not be enclosed. It should be positioned so that
loading and unloading can be performed without risk. It
must be possible to open the door fully. See the
recommended distances in the picture
Follow local safety regulations.
Once the placement of the sterilizer has been
established, anchor the sterilizer to the floor by each of
the three feet. This prevents the sterilizer from tipping. A
13 mm hole has been drilled in each foot. Use a screw
and plug intended for the surface in question. Make sure
there is a slight backward incline, i.e. the side of the door
should be slightly lower than the front, about 2 - 3 mm.
This is accomplished by placing a washer under each of
the front feet.

Electrical connection
IMPORTANT!
The electrical connection of the
unit must be carried out by trained
personnel
Prior to carrying out any connection work, ensure that
the characteristics stated on the nameplate correspon d
to the mains supply to which it is to be connected. In
case of uncertainty as to the unit supply voltage,
VOLTAGE FLUCTUATION:
The electrical components tolerate a supply voltage
fluctuation of between -10 and +10 %. For larger
fluctuations, it is necessary to use a voltage stabilisation
system placed between the circuit-breaker and the
processor unit transformer. In this case, contact the
sales office.
POWER-SURGE PROTECTION:
A power-surge protection device (over current
protection) must be placed on the sterilizer’s AC power
supply. This protection is the responsibility of the
customer.
CIRCUIT-BREAKER:
A device enabling the sterilizer to be electrically isolated
must be inserted on all the live conductors (including
neutral). This switch or circuit-breaker must be part of
the building’s electrical equipment, positioned near the
unit, and must be easily accessible and marked as the
power switch for the unit, while stating its function.
CAUTION!
The sterilizer must be declared to
your electricity supplier in case of
a 230 single phase connection.
If the unit is connected in polyphase. Its characteristics
are as follows:
• Breaking power 63 A breaking the 3 phases as well as
neutral
Earth terminal making it possible to connect the isolating
device to the earth conductor without braking it.
The on and off positions must be marked: I on and O off

INSTALLATION
CAUTION!
The water supply must be fitted
with a shutoff tap, as the sterilizer
must not be left without
supervision with the water
pressurized.
WARNING!
Risk of hot water from the drain
hose, exercise the greatest
possible caution.
Water connection
The incoming water must have a pressure between 1.5
bar and 6 bar with a temperature of about 15 °C.
Water quality <4 dH
The sterilizer is connected to a ½" water connection with
a shutoff tap. The sterilizer must not be connected with
hoses less than 12 mm. The hoses supplied with the
sterilizer are fitted with Gaz ½" G connections. The
hoses (two) are labelled “Inlet” and “Drain”.
The drain should be connected to a 6" cesspool, with a
capacity of 10 litres/min that can withstand 100° C.
Condensation can occur.
The drain hose must end at least 3 cm above the water
surface in the well.
The drain hose must not go higher than to the lower
edge of the chamber.
Diverse
Should the sterilizer be transported in temperatures
below -5 °C, the overheating protection on the sterilizer
may need to be reset. The error code Heating error
when a process is started indicates a symptom for this.
Keep all instructions and description of operation close
to the sterilizer.
Make sure the operator has read the User manual.
All other documentation supplied with the sterilizer must
be looked after by the operator. The documentation shall
be kept with the sterilizer until its service life comes to an
end.
