pressure pump. The Break-tank has a
level switch and an overflow pipe
discharging into the wash tank.
SP-550BP: Break tank has two (2) level
switches (high-low). Once the main
switch has been turned on, filling of
Boiler, Break tank and wash tank is done
automatically. Due to the two level
detection switches, the pump operates
alternately. The opening or closing of
the door has no effect on the first filling.
The drain pump works at the same time
as water enters the Break-tank, so that
water would flow into the washing tank
through the break-tank overflow pipe in
the event of a level switch failure.
Detergent dispenser
The dishwasher is prepared for its fitting
with an adjustable detergent dispenser, the
part number of which appears on the spare
parts list. This dispenser has to be installed
in the bottom front area, as shown on the
exploded view. At the rear of the wash
tank, there is an opening where to insert
the detergent injection nozzle.
The dispenser delivers about 0.7ml/s of
detergent (maximum). At the first filling of
the tank, feeding of detergent is roughly
56ml in 80s, resulting in a maximum
concentration of 3.5ml/l. At each cycle, the
dispenser delivers 10ml of detergent. It is
possible to reduce the injected quantity by
turning the adjusting screw on the
dispenser.
Rinsing aid dispenser
Verify that the rinsing aid reservoir is full.
With the machine running, actuate the
main switch several times (5 or 6) during
the washing cycle and check whether the
tube fills up with rinsing aid and goes in
the boiler. Setting the dispenser is done by
turning an adjusting screw on the front
lower panel in the direction shown on the
panel graph.
In order to determine whether the amount
of rinsing aid is adequate, look at the
glasses against the light. If there are water
droplets on the glass, the amount of
rinsing aid is insufficient; if streaks
develop, the quantity of rinsing aid is too
much.
Set of upper filters
In order to obtain perfect washing results
with heavy-duty machines, these can be
optionally fitted with a set of upper filters
(part number shown on the parts list). For
this purpose, it will be necessary to bolt the
rod supports in the holes provided in the
slides of the racks, as shown on Figure 3.
Then, place the filters on the said supports
and a longer drain plug for easier removal.
Machine Draining
Models with no drain pump: Remove the
overflow drain plug, leaving the filter in
place. Water will flow out by gravity and
dirt will be retained in the filter.
Models 'B' with a drain pump:
· Open the door and take out the drain
plug, leaving the filter in place.
· Press the drain control push (D), as
shown on the control panel, with the
door open. The drain pump operates as
long as the push-button
depressed, with the door open. Draining
will last about 55s.
· Put the overflow drain plug and filter in
place again.
· Turn the main switch off and close the
door.
Models "BP"
Draining of the Air gap-Break tank: In case
of extended non-utilization of the machine,
the tank should be emptied. To do so :
1. Drain the wash tank.
2. Close the water inlet.
3. Close the door: water will flow into the
wash tank by means of the pressure
pump.
4. Drain the wash tank.
When boiler draining is done by the
technical assistance service, the break-tank
is emptied through the boiler.
Tank cleaning
The tank should be cleaned after every
washing process, at the end of the day,
proceeding as follows:
· Open the door and pull out the drain plug
without lifting the filters, in order to
empty the tank and to prevent any large
particles from entering the suction
passage of the motor-pump. (Never
remove the aspiration filter when the
tank is dirty).
· Extract the upper filters as well as the
filter of the wash tank (H) and clean them
all thoroughly.
· On the wash pump inlet side, there is a
protection filter (L). To remove it, pull
gently.
· On models 'B' with a drain pump, also
remove the screwed-on filter of the drain
pump (J) to clean it. As shown on Figure
2, give the filter (J) a quarter of a turn to
unscrew it. After cleaning, screw the filter
on again.
· To clean the interior of the wash tank,
close the door and start the machine
(after having previously removed the
drain plug). In this way, water will enter
via the rinsing dispersers and the
machine will clean itself. This operation
should be carried out for 2 to 3 minutes.
· Finally, clean the bottom, walls and
interior of the tank.
· Spray arms must be cleaned periodically.
If rinsing is deficient, the cause may be
an obstruction of the jets. In this event,
dismount the arms and clean the jets.
· The outside of the machine MUST NOT BE
washed under a direct water jet; instead
is kept you can use a wet cloth and any ordinary
detergent.
· DO NOT USE any abrasive detergent
(etchant, concentrated lye, etc.) nor any
scourer or scraper containing normal
steel that will cause rust to develop on
the machine.
OTHER IMPORTANT REMARKS
· Before cleaning, servicing or repairing
the machine, it is necessary to unplug it
from the mains.
· When the appliance is going to be
inactive for a long period of time or at
night, the door should be kept open for
aeration and avoiding nasty smell.
· In case of a drain pump failure:
1. Drain the wash tank into a container
until the water level drops below the
drain plug.
2. With the drain plug in place, remove
the front bottom panel and change the
pump (this can be done without
moving the machine). In order to drain
the dishwasher manually, connect a
drain hose to the collector. On pulling
out the drain plug, water flows out of
the tank by gravity.
· In the event the power supply cable
should get damaged and have to be
replaced, the repair may only be done by
a SAMMIC approved assistance service.
· Airborne noise: the emission noise level
measured on a typical machine is inferior
to 70 dB(A) at a distance of 1m.
