(for Machine with drain pump the tank fills with water
and stops when maximum level is reached: empty the
tank manually and repeat the operation if needed).
WARNING! Do not open the dishwasher door
durino the washing cycle.
In case of accidental opening the cycle stops. If
You close the door, the cycle starts again from
the point where it had stopped.
At the end of the cycle open the door and pull out
the basket.
ACHIEVEMENTS
Any deficiency in the washing process is
apparent when dirty residuals are visible. Any
halos might be caused by an insuffucuent
rinsing: in this case, check that the rinsing jets
are clean and there is a sufficient pressure in
the water distribution network.
In the case that residuals are present, check
that:
• the washing jets are clean
• there is detergent
• the pump suction filter is clean
• the positions of the objects in the rack are
correct.
Adding Rinse Aid and Detergent
CAUTION
: Only use detergent and rinse aid
which are suitable for commercial washers, a
non-foaming industrial alkaline detergent.
Do not use any soap intended for a residential
dishwasher. This leads to large amounts of foam
building up in the washer and will void your
manufacturers warranty.
CAUTION
: Detergents for commercial
dishwashers cause corrosion. Always follow the
instructions on the packaging and drums.
CAUTION
: Do not mix different detergent
products, this could cause the dosing pump to
break down due to crystallization.
CLEANSING AGENTS
Choice of the suitable cleansing agent is an
essential condition if you want to obtain
extremely good washing results as regards
hygienic results. It is then important to consider
some points. First of all only highly alkaline and
chlorine-active antifoam products, especially
made for industrial dish-washing machines,
must be used and they must be produced by
well-known reliable Firms. Mean concentration
of the cleansing agents in powder must be
1,5÷2,5 g/lt. Mean concentration of liquid
cleansing agents must be 2÷4 g/lt.
In order to avoid scales and corrosions, put the
cleansing agent above water level on the
nearest area of the sucking pump filter, in this
way it will immediately dilute and will not deposit
on the tank bottom.
NSF 3-2009 requirements for detergent and
chemical sanitizer dispensers
Feeders (rinse-aid, or detergent) are
OPTIONAL.
When provided see instructions on page 31 in
this manual.
SANIFICATION
At least each 30 days it would be useful to do this
operation which guarantees the complete hygienic
conditions of the machine. We suggest to contact your
cleansing agent supplier who will give you quantity
and name of the most suitable product you can use
and that, generally, is an active chloride powder
(100÷200 ppm).
In order to avoid damage to the machine do not
increase the quantities and, once operations end,
rinse abundantly.
DESCALING
When hard water is used you can find, inside the
machine and also on dishes, calcareous sediments
which must be removed both for hygienic and
operating reasons by a descaling operation.
Operating process and frequency of this intervention
are suggested by your cleansing agent supplier who
has suitable products, generally containing phosphoric
acid.
In order to avoid damage to the machine do not
increase the quantities and once operations end rinse
abundantly.
RINSING ADDITIVES
To grant a perfect rinsing, a quick drying and to avoid
calcareous sediments on glasses and cups you must
add a surfactant on water (Brightener).
Your cleansing agent supplier will be able to suggest
the most suitable product. Your machine is equipped
with a rinse aid dispenser. Mean concentration used
is 0,15 g/lt.
