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. The dosage is automatic with the adjusting of the screw "I", which
after screwing to a full stop unscrew two turns.
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.
For filling the dosing tube, start the machine without plugging the overflow in:
at that point switch the machine on (pos.1) and off (pos.0).
Repeat this operation several times at intervals of few seconds, until the rinse
aid reaches the injector.
Wait until the machine reaches the correct temperature (lamp “C” on). 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.
