IMPORTANT NOTES
GB
Use in Accordance with Regulations:
The machine is an item of technical work equipment that is solely intended for use in a work environment.
The machine is intended exclusively for cleaning dishes, plates, cups, glasses, cutlery, trays and baking sheets etc.
Do not use for electrically heated cooking and heat conservation appliances.
Safety:
If a starch attack system is built in, the supplier must ensure compliance with all relevant safety rules
and regulations, thus reliably preventing the concentrated detergent coming into contact with the skin
or eyes !
Ensure that the operator wears tight-fitting clothing to prevent trapping hazard by the conveyor.

The “Attention” symbol is shown beside instructions that are essential for safe
operation of the machine.
Please read these passages thoroughly.
Liability:
Installations and repairs which are not carried out by authorized technicians, the use of parts other than
original spare parts or any technical modification to the machine not authorized by the manufacturer
will render the warranty set out in the standard conditions of sale invalid.
Important:
This Instruction manual is written for machines with an operating direction from left to right.
For machines with an operating direction from right to left, the same information applies but with
opposite handling directions.
Depending on the options and features of the machine, the indications on the display may vary.

with an extremely high mineral content, an external dematerialization unit is strongly recommended.
2.2.1. General information
?
OK
1
2
–– Connect water supply and drain pipes according to installation plan.
–– Line strainer and air gap are fitted to the machine as standard.
2.2.2. Fresh water supply for rinsing
–– DN 20 (3/4")
–– Should be soft (up to 4° Clarke, resp. 0.5 mmol/l).
–– Conductance 80 - 120 µS/cm
–– Must be cold if condenser is fitted.
–– Line flow pressure 1.5 - 6 bar at ~ 500 l/hr.
–– Provide shut-off valve on site.
2.2.3. Fresh water supply for tank filling
(CN Option)
–– DN 20 (3/4")
–– Should be soft (up to 9° Clarke, resp. 1.2 mmol/l) and warm
(50 - 60°C).
–– Conductance 150 - 400 µS/cm
–– Line flow pressure 1.5 - 6 bar.
–– Provide shut-off valve on site.
2.2.4. Drain connection

2.3. Steam or Hot Water Connection
Must be installed by an authorized technician and in accordance with local regulations.
Note:
On site, make sure that the pressures and temperatures for
the heating medium given in the installation plan cannot be
exceeded.
2.3.1. General information
?
OK

2
–– Connect supply and return pipes according to installation plan.
–– All connections are equipped with necessary fittings and valves as
standard.
2.3.2. Insulation
–– All pipes should be insulated.
–– Insulating material should be water, heat and shock proofed.
2.3.3. Adjustment of manual shut-off valve
with flow reducer for steam and hot water supply
–– The built-in manual shut-off valve is equipped with an adjustment
device to limit the heating supply medium.
A special tool is necessary for adjusting the valve-seat.
–– The correct adjustment is very important, particularly for higher
pressures, and therefore must be carried out by a HOBART-trained
service technician before first run or when changes are made to
the plant on-site.
–– The optimum adjustment is achieved when the nominal temperature
of the booster can just be held during continuous operation while
the valve is opened to maximum.
–– If the valve is opened too far, pressure shocks may occur when the
solenoid valve closes. This could cause damage to the installation.
–– If the valve is closed too far, the required heating-power cannot be
achieved.

Washing
GB
Note conveyor direction
Gastronorm pans and other large containers or boards should ideally be
washed in a separate Utensil Washer.
In Automatic Rack Type Dishwashers, these items may cause problems, such
as splash-over leading to low water levels in the tank/s and poor rinsing.
On the occasions when these items are to be washed, they should be loaded
sloping towards the direction of machine operation as shown in the picture. This
will reduce the problems described above.

14. Maintenance
14.1. General
In order to maintain the warranty and a continued safe, efficient, and
fault-free operation of the installation, it is necessary to perform the required maintenance work professionally.
For this reason, we recommend signing an inspection or maintenance
contract that ensures qualified support through a specially trained
customer service technician according to a schedule adapted to the
company needs.
14.2. Dishwashers with Heat Pump
The built-in heat pump of your dishwasher contains fluorinated
greenhouse gases covered by the Kyoto Protocol, and therefore,
falls within the scope of the EC Regulation 842/2006.
If the refrigerant charge is 3 kg or more and the system is not hermetically
sealed, you are obligated as operator of the refrigeration equipment to
carry out the following measures:
–– At suspicion of refrigerant charge loss, a leakage check by certified
personnel has to be arranged as soon as possible, and if necessary, the repair.
–– Equipment containing the refrigerant has to be checked for leakage
by certified personnel at least once every 12 months.
–– Any detected leakage must be repaired immediately by certified
personnel.
–– After a leak has been repaired, the equipment has to be checked
again for leakage within one month.
–– When putting the equipment out of operation, you are responsible
for making sure that the refrigerant contained in the equipment is
properly disposed of by certified personnel.
–– The above-mentioned diagnoses and/or measures must be recorded. These records have to be kept at least 5 years and submitted
to the competent authority on request.
For keeping records of checks, diagnoses, and measures, we
recommend using the following forms.
