adjust cable size to Amp rating; do not pull on supply cable or install it under
tension. If cable needs to be replaced use type H07RN-F.

INSTRUCTIONS FOR TECHNICAL PERSONNEL
2)WATER CONNECTION
Install a 55°C water tap in a well accessible place, terminating in a 3/4 " fitting,
which the pipe strainer and inlet hose shall be connected to. Carefully comply
with any national or regional regulations in force. The operating pressure
should be neither less than 2 bars or greater that 4 bars (200/400 kPa). If water
pressure is inferior then 2 bar, a pressure increase pump is necessary. If water
pressure exceeds 4 bar, a pressure reducer is necessary.
In order to obtain best results, it is suggested that the water supply have a
hardness not greater that 15°F.
3)WATER DRAIN
Arrange a water drain towards the floor with siphon and connect the machine
with the flexible tube given with the machine, so that it leans towards the drain.
Moreover, make sure that the hose does not have constrictions. Make sure
that the building drain tubing withstands temperatures up to 70°C.
4)RINSE AID DOSAGE
Make sure that rinse aid suction hose is correctly installed in it's proper
container.
Adjusting the dose:
-regulate by means of the screw , turning clockwise (-) to decrease the
quantity or anticlockwise (+) to increase it.
Start the machine (as described in paragraph OPERATIONS AND USE).
Fill during the wash cycle by opening (slightly) and closing the door
until the hose has completely filled.
At this point the machine automatically takes the necessary liquid for every
rinse: during the washing operations, check that the liquid of the container
does not run short.
Make some empty cycles, then try to wash: if the objects washed show some
drops, this means that the rinse aid is insufficient. On the contrary, the
presence of marks can mean that there is too much rinse aid or the water is
too hard. The regulation can change according to the kind of rinse aid.
5)DETERGENT DOSAGE (for machines with built-in detergent dispenser)
With the screw on the side of the detergent pump, close completely the
product intake, then slowly open the screw until the desired intake quantity has
been reached. The correct quantity is indicated by the detergent supplier.
Check that the intake of the pipe during the rinse cycle is as preset. (8cm = 1g
approximately). Maximum intake or delivery distance: 2 meters.
