Quick guide
Pour cold ater into the bath so that it reaches the minimum tank fill line (but does not
go over the maximum fill line).
Add the required dose of detergent (see pg 30).
In order to save the cycle data to the MC card, ensure that the MC card is installed in the
port prior to turning the machine on.
S itch on the machine via the s itch at the rear of the unit, on the left hand side, above
the electrical mains lead.
If the ater is belo the minimum temperature, the Hygea 6427 ill automatically start
degassing and heating the liquid.
Once the ater is heated to the minimum operating temperature, the Hygea 6427 is
ready to use, although an extra degas cycle may be required.
Select your operator identification.
Press the “ENTER” key to start the cleaning cycle.
REMEMBER
-Al ays keep the bath full of liquid hen in operation.
-Do not put hot ater into the bath.
-Al ays use the baskets to support items to be cleaned.

connected to the manifold to allo the internal surfaces of the instruments to be cleaned.
All tubing connections are made via small stainless steel clips.
To use these, press the small stainless clip in to ards the pipe and pull the connector straight up,
the connector is then pushed into the other receptacle.
1. The tubes can be connected to the manifold by inserting the connections into the luers located
on the manifold.
2. Connect the basket by inserting the connector into the luer located on the top of the tank.
3. Connect the other end of this hose to the manifold located on the basket.

4. The instruments can be connected by inserting the correct size connector into the tube and
then connecting the hollo instrument.
5. The instrument and hose can then be connected to the manifold.
Important: he tubes must be connected whenever the Hygea 6427 is in use; not doing
so may cause the pump to burn out. his may invalidate your warranty.

the rear of the unit.
When the Hygea 6427 is first s itched on, the follo ing screen ill appear for
approximately 5 seconds.
While this screen is displayed, the buttons are inoperative. This is normal as the Hygea
6427 is running through its start-up routine and checking all internal systems are orking
correctly.
The top line of the display indicates the Hygea 6427 serial number. This uniquely
identifies the machine.
After 5 seconds, the Hygea 6427 is ready for use.

The Hygea 6427 is fitted ith a liquid temperature sensor. If this temperature is belo
the minimum set cleaning temperature (20
o
C), the follo ing screen ill display.
The Hygea 6427 ill automatically start heating and degassing the liquid.
When the liquid reaches the required temperature, the follo ing screen ill be displayed
and the Hygea 6427 ill be ready to use. (The actual min. and max. temperatures may
be different from those indicated belo .)
Press the “Accept” button to continue.

screen displays to confirm that detergent has been added:
Press the “Start” button to confirm that the liquid contains detergent. (See page 30 for
information about detergents).
The Hygea 6427 ill then begin the cleaning cycle. During the cycle, the lid ill lock and
cannot be opened until the cycle is completed or aborted.

11
Starting a cycle
The Hygea 6427 is factory pre-set ith a total cycle time of 15 minutes. This consists of
3 consecutive cycle stages of 5 minutes and the countdo n ill display from 5 minutes.
During this cycle, the irrigation pump ill operate three times, once at the beginning of
each cycle stage.
The default pump cycle time is set to 1 minute. Under these parameters, the pump ill
run during the 1
st
, 6
th
and 11
th
minutes. If the pump time is set to 2 minutes, the pump
ill run during the 1
st
and 2
nd
, 6
th
and 7
th
and 11
th
and 12
th
minutes.
While the pump is in operation, the ord “pump” ill display on screen:
When the pump is not in operation, the follo ing screen ill display: The default
ultrasonic cycle time of the Hygea 6427 is 15 min. The follo ing screen ill appear.
The cycle can be aborted at any time by the operator, by pressing the “Abort Cycle”
button and the cycle time can be changed in Administrator mode. Please refer to pg 11 of
the Administrator Instruction manual for information on setting the cycle time.

If the cycle validation mode is set to save to the MC card (either as ell as or instead of
the hard copy ticket), a digital record can be saved to the supplied MC card.
Note: in order for the data to save to the card, the MC card must be inserted into the MC
port on the control panel before your Hygea 6427 is s itched on.
The digital cycle traceability ill save the information of each cycle (as sho n on the
ticket on page 12) to the MC card.
This information can then be transferred to a PC and an electronic copy saved, using the
Ultra ave Cycle Validation soft are supplied on the MC Card. It is recommended that the
MC Card is removed and the information transferred to the PC at the end of each clinical
session (t ice a day).
When the data recording is complete, the follo ing screen is displayed:
To print another copy, press the “Yes” button. This can be done as many times as needed.
If a copy of the print-out is not required, press the “ESC” button.
The lid ill then unlock, allo ing removal of the instrument trays.

he cleaning cycle does not start
If the screen displays a “Lo Fluid” arning as belo , the bath ill not operate until the
unit is filled to the correct level and the detergent dose added.
If the screen sho s a “Lid Open” arning, the cycle ill not start until the lid has been
closed.

15
Cycle abort messages
If the cycle aborts, the reason ill be displayed. The print-out ill record a process fail
and give the reason, and an audible arning ill sound to signal a process fail. To turn off
the audible arning, press and hold the “ENTER” button at the bottom of the screen until
the arning stops.
If the operator aborts the cleaning cycle, the follo ing screen ill be displayed:
If the fluid level drops belo the required level during operation, the cleaning cycle ill
stop and the follo ing screen ill be displayed:
Important: The operator must ackno ledge this by pressing and holding the “EN ER”
button to complete the aborted cycle.

16
If the lid is opened during operation, the cleaning cycle ill stop and the follo ing screen
ill be displayed:
It is important that you do not turn off the main electricity supply to your Hygea 6427
hen it is running a cycle.
The Hygea 6427 recognizes hen the main electricity supply fails during a cycle and
prints a report (and/or creates a record on the MC card) hen the machine is next
s itched back on.
The cycle ill be recorded as an aborted cycle.
If the cycle fails due to a po er failure, the follo ing screen is displayed hen the po er
is restored:
Important: the operator must ackno ledge this by pressing and holding the “EN ER”
button to complete the aborted cycle.
If the MC Card is not present, and “MC Card Only” is selected as the validation mode, then
you ill not be able to run another cycle until an MC card is inserted. A message of
