Long 6 min, 10 s.
All three programmes are 30 seconds shorter when washing
without Granules.
Starting
Press the start button (1). The machine is pre-programmed so
that it cannot be started if the temperature in the wash tank is
lower than 65 °C at the time of the first start once the water
has been added. The lock is set to 60 °C for subsequent starts
so as to achieve complete washing. Washing at too low a tem-
perature increases the risk of foam formation and the items
to be washed failing to wash clean. Reprogramming may be
carried out by authorised personnel only.
While the programme is running, the display shows which
programme is being run, how much programme time is
remaining and the temperatures in the wash tank and rinse
tank.

When the wash programme is complete, the hood rises auto-
matically and the display shows the most recently operated
programme, for example:
You can now reload the machine and run the next pro-
gramme. Close the hood even if you are not running another
wash programme straight away. This saves energy and reduces
water vapour evaporation.
Operation
The wash programmes short, normal and long start with
washing with Granules for 1, 3 or 5 minutes, they then con-
tinue without Granules for 30 seconds. The final rinse is set
to guarantee a water temperature of 85 °C for 30 seconds. If
the machine has the steam reduction function fitted, the pro-
gramme with take an extra 30 seconds to cool the air in the
machine and so reduce the amount of steam escaping into
the dishwashing area or kitchen.
Stopping the machine while in operation
If you want to stop the machine before the wash programme
is finished then change to washing without Granules for
about 30 seconds to rinse any remaining Granules from the
items being washed. Then press the STOP button. If the
programme without Granules is selected and if it is impera-
tive that the machine is stopped then you can press the stop
button immediately.
NB! The pots and pans may have detergent on them and should
be washed before being taken out of the machine and used!
Inspection of pots
As with all washing up, it is important that staff check the
results. Remove any Granules that have got stuck onto pots or
corners, sharp angles or other inaccessible places (fig. 12).
PowerGranules®
The Granule potwashing machine from GRANULDISK
AB works best with our specially designed PowerGranules.
They are manufactured to provide the best results, as well
as the longest possible working life for themselves and the
machine. The warranty only applies if PowerGranules from
GRANULDISK AB are used in the machine. The plastic
material in the Granules is approved for use in contact with
food. We recommend that all Granules are changed at once,
several times a year.
HACCP Operation and Hygiene documentation
GD 700 meets the most stringent requirements for disinfect-
ing cleaning of items to be washed by guaranteeing a heat
treatment of these items equivalent to 3 600 HUE (heat
unit equivalents in accordance with ANSI/NSF 3, 2001.)
This hygiene level exceeds set European requirements and
is equivalent to the most stringent hygiene requirements set
internationally.
GRANULDISK®Documentation Tool, GDTdirect™, is an
integrated function for the documentation of the dishwashing
machine’s operating parameters and critical hygiene control
points, HACCP. Operating data for the last 100 wash pro-
grammes run is viewed directly in the control panel window.
An external computer can be linked to the machine and oper-
ating data stored in separate files so that all historical data can
be saved. See also page 16.

The collection and cleaning of granules/
Place the Granule collector in the basket wheel. It is impor-
tant that the collector is placed as far forward as possible on
the basket wheel. (Image 13)
Start the special Granule collecting programme is activated
by first pressing the STOP button and then pressing in the
normal programme (4) and Granule programme (6) buttons
at the same time for three seconds.
After the programme has finished lift out the Granule collec-
tor and place it in the sink. Rinse with clean water and move
Granules around with hand to reveal and remove solid food
remains such as bones.
Note: Do not use disinfectant or other cleaning products as the
residue from these can cause frothing.
Check the amount of Granules after evening them out in the
collector. The machine should contain about 8 kg, which is
marked on the side of the collector (14). Add more Granules
if the level does not reach the markings. We recommend that
all Granules are changed at once, several times a year.
Check that there is no foreign matter in the wash tank and
that the bottom sieve is clean.
NB! Too many or too few Granules may cause an inferior wash
result. Too many can also result in blocking of the spray nozzles.
Emptying tank
Press the STOP button, then open drain tap to empty wash
tank (fig. 15).

4. HACCP Hygiene and Operation Documentation
Storing data on an external computer
To store complete operating data for the machine, it needs to
be connected to an external computer via a serial cable. Soft-
ware is installed on the computer which gradually collects
and stores operating data from every wash programme run.
For storage to take place, the computer has to be switched
on and the documentation program has to be active. Data is
transferred and stored in the selected folder on the computer
after every programme run. This program can be active with-
out stopping the computer being used normally.
It is also possible to download the last 100 programmes by
selecting “Washer/Get all log data” if the computer has not
been connected. Note: Duplicates may appear in this mode.
Connecting the cable
A 10 metre cable and serial contact are supplied upon deliv-
ery for connecting to the machine and a computer. If the
computer does not have a serial port, what is known as a USB/
serial adapter can be used. For information on what is suit-
able for your particular computer, contact your IT specialist.
The cable is connected to the 9-pole contact at the detergent
container for the machine. Check that the internal cable
is connected in the machine’s electrical cabinet to the J11
terminal on the control card. This cable is then laid to the
selected computer via the kitchen’s normal communication
paths and connected to a free COM port.
Software installation
The program is supplied on a CD and is installed as follows:
1. Create a folder for the program on your hard disk and give it a
name. Use “Explorer” in your computer’s Office package.
2. Insert the CD and click on the program file gdt-direct.zip
on the CD. Save the files in the folder you just created on
your hard disk.
3. Tip: create a shortcut on your desktop to make it easier to
find the program when you want to run it.
Running the program
1. The program is run by double-clicking on the program file
gdt-direct.exe in the folder you created on your hard disk, or by
clicking on the icon you created on your desktop.
2. Once the program has started, you have to select the port to
which your dishwashing machine is connected. Click on Ports
and select the correct port.
3. Then select Washer, followed by Connect.
4. A window appears on screen and you have to select where you
want to save the log file. Select the folder created as described
in “Software installation” above, and name the file.
Tip: name the file after the week or month to make it easy to find
the operating data stored. Example:; “HACCP-w.17-2005”.
New data will be saved in the same file after data saved previ-
ously until you choose to give the file a new name. Rename the
log file at regular intervals so as to ensure that the list does not
become unnecessarily long.
16

5. Data is displayed directly on the computer screen: see the
figure on the next page. The view is of a fixed size that
cannot be changed, and the table headers are in English.
The column width can be changed by placing the mouse
in the table header and dragging.
The following information can be viewed (left to right):

ules – G/washing with Granules or NO/washing without
Granules; Temperature in wash tank; Temperature in rinse
tank; Information on nal rinse sufcient – OK or NA if the
rinse volume has been reduced.
To read all data, the program must be running and the com-
puter connected to the dishwashing machine.
Data processing
Data can be further processed by selecting View from the
menu, followed by Log file. To read data saved in older files,
use “Explorer” and click on the relevant file name in the
folder in which these files are saved. The information can
be cut and paste from the Log file into Excel, for example,
for statistics processing. Saved files can also be placed on a
shared server or be e-mailed to a central HACCP manager,
for example.
