6. OPERATION
Industrial dishwashers are designed to wash large quantities of dishes economically
and quickly. In this regard, they differ from household dishwashers. The performance
of industrial
dishwashers also depends on external factors. Such as the quality of detergents used,
water temperature at
inlet, inlet water pressure, water hardness, etc.

For long service life of your dishwasher and good washing results, be sure to monitor
the calcium level in the water. If the water is calcined, be sure to use a water softener.

supply of water and electricity.
After all checks, move the control knob from the OFF position to the
any program. When you
first start the dishwasher, it will automatically check the water level. If the tank is empty or the water level is
insufficient, the machine will add water to the required level. During this period of time, the cycle lamp will
blink at intervals of 0.8 seconds. Upon completion of the water intake process, the cycle lamp will go out
and the heaters will begin to operate. If the water intake process does not finish within 5 minutes, the
cycle lamp will give a signal, blinking at intervals of 0.3 seconds. After filling the water to the required level,
the boiler is activated first, and then the boiler heater.
Before starting washing programs, you must wait a certain time for the water heaters to heat up. The
length of time the dishwasher heats up completely cold or freshly filled water varies depending on the
inlet water temperature and lasts on average 30-45 minutes. When the rinse water temperature in
the boiler reaches 85°C, the green lamp in the dishwasher lights up, which means the machine is ready for
use. To use a dishwasher that has finished heating, place the basket in the dishwasher and close the
door. In the TW.H50 model, after closing the door, the washing will begin according to the set program.
In models TW.F50 and TW.F40, after closing the door, you must keep the START
button pressed for 1 second. During the duration of the program, the cycle lamp will blink at intervals of
0.8 seconds. At the end of the washing process, after waiting for 5 seconds, rinsing will start
automatically. Dishwashers have a hygienic rinse function. The machine runs until the rinse water
temperature reaches

13
Machine Translated by Google

85°C and if this temperature is not reached during the wash cycle, the machine
will automatically extend the wash time. When the rinsing water temperature
reaches 85°C, the machine washes for another 10 seconds and then proceeds to
the rinsing process. This function guarantees rinsing at 85°C in accordance with
HACCP hygiene standards.
If the rinse water temperature cannot reach 85°C within 8 minutes, the dishwasher
will rinse at the existing rinse water temperature and end the program cycle. But if
such a situation occurs, the cycle lamp, blinking at intervals of 0.3 seconds, will
give a signal to the user. When the door is opened during washing, the
washing process automatically stops. When the door is closed, the program
continues from where it was stopped. To cancel the washing process, you can reset
the washing program by long pressing the START button. To remove water from
the dishwasher,
the control knob must be moved to the pump position. After this, you must press
the START button for 1 second. This function is only supported on models with a
drain pump. In models without a drain pump, no processes occur in this mode.
Before starting the pumping process, do not forget to remove the plug
located inside the dishwasher. Once pumping is complete, reinstall the plug before
using the dishwasher again. After removing water from the dishwasher, be sure
to complete the pumping process with the control knob; do not allow the drainage
pump to operate for a long time without water. Since the dishwasher is designed
for serial operation, if it is left idle for a long time (for
example, at the end of the day), be sure to turn it off. To turn off the dishwasher,
move the switch knob to the OFF position.

7. OPERATING INSTRUCTIONS
• The dishwasher is manufactured for industrial use and must be used by qualified
personnel. • For good cleaning
performance, it is recommended that the water hardness be between 0-10 Fr. If tap
water exceeds these values, it is recommended to use
call a water softener.
• Before loading dirty dishes into the machine, you must first wash off any
remaining food from them. Otherwise, food residue left on dirty dishes may clog
the filters. • Do
not move the dishwasher during operation.
• Adjust the dosage of detergent and rinse aid used in the dishwasher according to
the recommendations of the manufacturer of these products.
• The quality of detergents used in a dishwasher is of great importance in terms
