Table 1: Model variants pasta cooker
2. Installation and setting up
2.1. Floor standing devices
When setting up the pasta cooker, the following points must be observed:
•The distance from the back wall of the pasta cooker to the next wall must be at least 100 mm.
•The pasta cooker must not stand on a ammable surface or be built into a ammable unit. The local safe-
ty, re police and building regulations also apply. The requirements of the food inspectorate must also be
observed.
•The pasta cooker is a xed device. The roles are only intended to facilitate maintenance and cleaning
work. These can be removed by simply notching them as required. The device must not be moved during
operation.
•The normal height of the device is 850mm. This can be increased to 900mm with a substructure as re-
quired.
•After setting up the device, the power plug must be accessible.
2.1.1. Stability
Due to insufficient stability, the TW-350 must not be set up freely. It must be attached with the angle plate in-
cluded in the scope of delivery.
Self-tapping screws can be used for fastening in the sheet metal. For wall or oor mounting, we recommend us-
ing screws with dowels.
2.1.2. Mounting the substructure
•Loosen hexagon nuts (6pcs) on the inside of the oor.
•Slide in the substructure.
•Tighten the hexagon nuts again.

3. Power connection and technical information
3.1. Power connection
•The device may only be connected by trained specialists.
•After connecting, the device starts and an automatic calibration takes place.
•Then the software version (for example Gastro 8.67) can be read on the display.
•The 3x 400V (3L + N + PE) power connection is made with a CE plug that conforms to standards.
See appendix 1
•The connection diagrams can be found in chapter 10.4 appendix 4.

5. Operation
5.1. Customer parameters
Certain parameters can be changed by the customer.
5.1.1. Call up the parameter menu
If the machine is in the OFF state, you can switch to the parameter menu by pressing the key or for 10
seconds.
5.1.2. Change parameter pages
The various parameter pages can be called up with the key .
5.1.3. Change parameters
The parameters can be changed with the keys and .
5.1.4. Exit the parameter menu and save the new values
To exit the parameter menu, press the key .
The changed values are saved and are retained even in the event of a power failure.
5.1.5. Example of the parameter menu
Figure 3: Parameter menu
5.1.6. Modiable parameters
•Sound-Level:
The volume of the buzzer can be changed between 0 (off) and 10 (very loud).
•Standby- time:
The standby time for the TW can be set between 5 and 120 minutes. If the "-" button is pressed for 5 min-
utes, the standby mode is switched off(Off)
•Standby- temperature:
The standby temperature of the TW can be changed between 30 and 80 ° C.
•Monitoring drying cycle:
After switching on, the temperature must not rise more than the set temperature difference (10-80 ° C) for
the rst 60 seconds. If the temperature rises more, an error message is output (too little water / oil) and
the control goes into the offstate.
•Temperature limit for the clean function:
If the temperature is higher than this set temperature, the clean function is blocked.
11_Operation manual Pastacooker Gastro 8 V1_3_e Page of Rorschach, 19.03.20187 19

•Monitoring salt water salinity alarm
With the pasta cooker, the salt content monitoring (salinity alarm) can be set between 1 ‰ and 30 ‰.
(Default values: Low = 8 ‰ and High 12 ‰) If these values are exceeded or not reached, the background
color changes after the set measuring time (time 1 - 60 seconds). The salt content is displayed with the “+”
and “-” button combination and the alarm is reset by pressing the“+” button.
•Salinity alarm (sound):

Temp !Acoustic alarm when the TW is switched on and the temperature is> 90 ° C.
Lift !Acoustic alarm when the TW is switched on, the temperature> 90 ° C and a HUB is

•Interval time for the contactor control (only with relay operation, not with SSR):
The interval time can be set from 2 to 60 seconds. The following settings then apply:
•Interval time: 2-9 sec., If the temperature deviates by> 1 ° C, heating takes place.
•Interval time: 10-19 sec., If the temperature deviates by> 2 ° C, heating takes place.
•Interval time: 20-60 sec., If the temperature deviates by> 4 ° C, heating takes place.
•ABCD bus:
The ABCD bus must be activated in the Gastro 8 control!
The ABCD interface for energy management can be switched on or offvia the menu (changeable parame-
ters) for controls that do not have a ball valve (SW2-3) or a lifting motor (SW1-8). If the control has neither
a ball valve nor a lift motor, the lift motor 2 OPEN relay is used as output A. When the ABCD bus is activat-
ed (changeable parameters), it is not monitored whether a ball valve or lifting motor has been activated
with the DIP switches or not.
A: Relay ball valve (230VAC) or relay lift motor-2 OPEN (230VAC)
B: Relay heating (230VAC)
C: Relay contact to interrupt the control of the SSR
D: neutral conductor.

•Demo-Mode:
If the demo mode is activated (20-240 seconds), a key press is simulated after the set time. First a key
press "PROG1" and the next time a key press "PROG3" is simulated. The programmed time will run down
normally and then the time (demo mode time) will be waited until the next key is simulated. A program
can be canceled at any time. This demo mode is intended for a long-term test or for a demonstration dur-
ing presentations.

The automatic basket lifting function automatically lifts the pasta basket out of the water when the time has
elapsed.
As soon as the time has been programmed, the relevant program button can be pressed.
With the pasta cooker there are 2 programs on the lift right and 1 program on the lift left and a common button
for lift right and left. By pressing the respective button, the corresponding lift moves down and up again after

safety procedures!
11_Operation manual Pastacooker Gastro 8 V1_3_e Page of Rorschach, 19.03.201812 19

6.4. Salt check
With this option, the salt content of the water can be checked, making it easier for the customer to ensure the
consistent quality of the pasta.
With the TW, the monitoring of the salt content (salinity alarm) can be set between 1 ‰ and 30 ‰. (Default val-
ues: Low = 8 ‰ and High 12 ‰) If this value is exceeded or not reached, the background color changes after the
set time (time 1 - 60 seconds).
If there is too little salt, after the set time (Salinity Alarm Time), the background lighting changes to purple and
an acoustic alarm may sound (Salinity Alarm Sound).
If there is too much salt after the set time (Salinity Alarm Time), the background lighting changes to blue and an
acoustic alarm may sound (Salinity Alarm Sound).
If the salt content changes back into the valid range, the background lighting changes to the normal color and
the acoustic alarm is ended.
The salt content is displayed with the key combination “+” and “-” and the alarm is reset by pressing the “+” key.
A salt concentration of 1- 1.2% is perceived as optimal (10-12g per 1 liter of water)
The interval of the acoustic alarm is 10 seconds. When exceeding or falling below the limit values, different tone
sequences sound ...
