1.10 Rinse-aid dosing pump functioning (pict. 7)
Functioning: The dosing pump is powered by the pressure generated by the rinse pump, used
to load a spring.
The release of the spring generates the suction of the rinse-aid chemical from its container to the
boiler.
To prime the rinse-aid pump, run some wash/rinse cycles.
Adjustment: The dosing pump takes a determined quantity of rinse-aid chemical at each rinse.
This
quantity is adjustable from 0 to 0,24 cubic inches (from 0 to 4 cm³), equivalent to circa 0 to 11
inches (from 0 to 30 cm) length of the suction hose.
Turn the adjustment screw clockwise to reduce capacity.
Turn the adjustment screw anticlockwise, to achieve the maximum capacity (up to 20 turns).
1.11 Thermostop Function
The machine features a standard Thermostop safety system.
The Thermostop system guarantees that the rinse cycle is started only when and if the water temperature in the boiler has
reached the temperature selected in the SET RINSE TEMP. parameter (see paragraph 4.1.2).
The duration of the wash cycle is extended in time till the water temperature in the boiler has reached the set temperature.
The
wash cycle gets longer in time if the machine is fed with water at the wrong temperature (cold water, below 122°F - 50°C)
or if there is a failure in heating the water in the boiler.
1.12 Heat Recovery system - installation (optional)
The machine can be equipped with a built-in Heat Recovery system (TR).
The Heat Recovery system reduces signifi cantly the humidity in the dishwashing-room.
In case the machine is equipped with the Heat Recovery system, the
water in-feed must be done with cold water
(min 41°F - 5°C / max 59°F - 15°C).
IT IS STRICTLY FORBIDDEN TO CONNECT THE MACHINE'S VENT DIRECTLY WITH THE OUTDOOR!
COLD WEATHER CONDITIONS MIGHT SERIOUSLY DAMAGE THE THERMAL RECOVERY SYSTEM AND
THE STEAM CONDENSER.
