– Connect supply and return pipes according to installation plan.
– All connections are equipped with neccessary fittings and valves as
standard.
2.3.2 Insulation
– All pipes should be insulated.
– Insulating material should be water, heat and shock proofed.
2.3.3Adjustment of shut-off valve
A
with flow reducer for steam and hot water supply
– The built-in 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 particulary for higher
pressure, and therefore must be done by a HOBART trained service
technician before first run.
– The optimum adjustment is achieved, when the nominal temperature of
the boiler can be held during continuous operation.
– If adjusted too far open, pressure shocks may occur when the ­solenoid
valve closes. This could cause damage at the ­installa­tion.
If adjusted too far close the required heating-power cannot be achieved.

2.4 Exhaust connection
– Connection must be carried out in conjunction with competent
ventilation engineer.
– Please pay attention to notes on the service drawing.
min. 30 cm
2.4.1 Exhaust into the kitchen
– Only possible in connection with Heat Pump System and sufficient room
ventilation.
– Avoid condensate damage by mixing exhausts from vent outlet of the
machine, directly with room air (air distributor).
10 cm
2.4.2 Exhaust pipework
– Leave a distance (approx. 10 cm) between machine exhaust and site
channel or connect special exhaust stack (option).
– Use additional ventilation fan, as the built-in ventilator has no
compression.
The volume of air to be evacuated from site has to be larger than the
volume of air of the machine (see installation plan).
– To prevent corrosion damage, provide exhaust channel in stainless
steel or synthetic material.
– In case of extremely low temperatures:
Provide insulation and anti-freeze shutter.
2.5 Dispensers for detergent and rinse aid
– Normally dispensers and controls are delivered and installed by the
detergent and rinse aid suppliers.
– Install dispensers, controls and containers such that they are easy to
handle and do not disturb machine operation.
A
– Rinse aid connection (A) is provided above the rinse booster heater
(R 1/8" inside).
– Terminals (230V~) are provided in the control box (see wiring diagram).
Please see separate installation instructions.
It is recommended that dispensers and their controls are not fitted
directly to the machine! (The panels have thermal insulation.)
Use only commercial detergent and rinse aid ­(suit­able for
professional and industrial operations).
Please pay attention to the manufacturers safety instructions.

Preparation / Operation
7.1 Racking (Remove coarse food soil before washing.)
When loading plates
consider the machine 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.

13.1 General
For trouble free operation we recommend an inspection or maintenance
contract by qualified Service technicians.
13.2Dishwashers with heat pump
The heat pump built-in in your dishwasher contains fluorinated
greenhouse gases covered by the Kyoto Protocol and therefore
it falls within the scope of the EC Regulation 842/2006.
As this is not a hermetically sealed system and the refrigerant charge
is more than 3kg, you are obligated as operator of the refrigeration
equipment to carry out 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.
– Equipments 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 that
the refrigerant contained in the equipment is proper disposed of by
certified personnel.
– The above mentioned determinations 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 the recording of checking, determinations and measures we
recommend to use the following forms.
