Connect the cold, hot and deionized (if available) water hoses, exiting the machine with their respective network connections, as shown on the installation diagram. It will be the responsibility of the installer to make sure that the temperature of the cold water supply is correct, otherwise proper washing of materials cannot be ensured. The connections for cold and hot water must not feed any equipment other than the glass-washer. During the washing cycle, this is necessary to prevent the subdivision of the water supply with other users, thus leading to a substantial increase in the time required to fill the chamber (in this case an alarm will be triggered to alert the user that the maximum time allowed for water loading is exceeded).
- If the machine is provided with a deionized water feeding system but the plant is not equipped with it, the cold and deionized water hoses should be connected together.
- The machine can be equipped with a built-in softener, which has the function of reducing the scale in the water supplied
- Connect the flexible hoses to the machine valves positioned in view at the back, making sure to connect them correctly based on the sales configuration.
- Make sure to connect the water flexible hoses in the positions shown in the picture below.
- Connect the water flexible hose to connections shown in the picture below.
- If present, install the Disconnector CA while maintaining a clear area of 6″ (150 mm) around the valve (For more information see the Installation Plan). The water supply taps must be capable of quickly stopping the water line, therefore, they must be equipped with a ball or a gate valve. They must also withstand the operating pressure of the water, as indicated in the technical data sheet.
Proper placement of the taps is shown on the installation plan.
HAZARD! Be careful in case of a blockage of the drain which could cause spill out of water and the risk of slippery floor.

WARNING! During this operation, check that the plastic cap is closed.
4) Insert the rack and start a normal washing cycle. The machine regenerates automatically.
WARNING! The washing cycle performed after the <salt loading> may not work.
Regeneration Salt
If the water softener was chosen when configuring the machine, the glasswasher is supplied with regeneration salt which will feed the device automatically during the regeneration process.
You must fill the salt tank every time the message “Refill salt” is displayed.
- Use only appropriate coarse-grain salt.
- Do not use kitchen salt, crushed salt tabs or other types different from those indicated, as it may contain insoluble substances.
- Do not pour cleaning liquids or other solutions in the salt tank.
WARNING! Failure to comply with these recommendations can lead to a malfunction of the water softening device. Just before the salt runs out completely, the display will show the message «Lack of salt». At this point, the salt should be topped-up as soon as possible, otherwise an error message will appear and it will no longer be possible to activate a new cycle if not by resetting.
The salt must be introduced through the chamber outlet inside the tank (#4 in “chamber filters section”). To introduce the salt, unscrew the cap (anti-clockwise) and fill the tank with salt funnel, paying attention not to pour salt outside the bowl then close the tank with the cap.
Salt Refill
Proceed as follows to refill the salt:
1) Delete the message on the display by pressing the RESET key for 5 seconds.
2) Open the door and remove any already inserted load.
3) Loosen the salt tank cap and insert the funnel.
4) In the first filling, introduce 0.13 US gal (0.5 l) of water to dissolve the residue salt. FIRST FILLING ONLY
5) Fill with salt up to the edge.The tank contains about 1.5 lbs (0.7 kg) of salt.
6) Thoroughly clean the edge of the salt tank.
7) Tighten the cap again.
8) Run a «Prewash» program to clean the salt residues inside the wash chamber.
- It is absolutely necessary to remove any salt residues that may have settled in the chamber after refill and before rinsing.
- After each top-up, start the «Prewash» program. In this way, any salt grains will dilute and rinse out. Salt residues and the overflowing water and salt solution can cause corrosion if they are not rinsed.
Following the instructions in the chapter “Starting the Machine”, start a «Prewash» program.
IMPORTANT NOTE! After the salt refill action, the first wash cycles may fail.
IMPORTANT NOTE! The “Refill Salt Tank” alarm may persist for few hours after the salt refill action, until the brine is being created. This will not affect the functionality of the device.
Automatic Regeneration
It is possible to have a water softening device that can completely regenerate at precise intervals. This process is fully automatic. Regeneration will be implemented before the selected program is activated.
