IMPORTANT NOTES
THE ORIGINAL INSTRUCTIONS.
ONLY TRAINED OR AUTHORIZED ADULT PERSONS OPERATE THE MACHINES.
USE IN ACCORDANCE WITH REGULATIONS
The machine is technical work equipment for express use in the work place.
The machine is exclusively to be used to wash ware such as plates, cups, glasses, cutlery, trays etc.
Do not use for electrically heated cooking and heat conservation appliances.
SAFETY:
Never hose down the machine.
The “Attention” symbol is shown beside instructions that are essential for the safe operation of the
machine.
Please read these passages thoroughly.
LIABILITY:
Installations and repairs which are carried out by non-authorized technicians or the use of other than
original spare parts, and any technical alterations to the machine, may affect the warranty set
out in the standard conditions of sale.
The machine can be used by one person only, does not allow two or more people operate at the same time.
MACHINE NOISE LEVEL:
The machine noise level is ≤ 70 dB (A).
USING ENVIRONMENT
Electric equipment shall be capable of operating correctly in the intended ambient air temperature. The minimum
requirement for all electrical equipment is correct operation between air temperature of +5℃ and +40℃.
The electrical equipment shall be capable of operating correctly when the relative humidity does not exceed 50% at a
maximum temperatrue of +40℃. Higher relative humidities are permitted at lower temperatures (for example 90% at
20℃).
Electrical equipment shall be capable of operating correctly at altitudes up to 1000m above mean sea level.
The equipment are not used in the potential explosive environment.
CONNECTING TENSIONS:
The machine described in this operation manual has following connecting tensions:
400 V/50 Hz/3 Ph/N/PE or 230 V/50 Hz/1 Ph/N/PE
GENERAL INFORMATION ON WASHING GLASSES AND CUTLERY:
The local supply water quality has a major impact on the wash and rinse result. A high content of minerals which are
dissolved in the water during the drying process may become visible in the form of spots and streaks.
Authorised service personnel can determine the content of minerals by measuring the electrical conductivity. Values of
less than 80 Microsiemens/cm indicate a low content of minerals. Higher contents need to be reduced below the critical
level by demineralising the water using specic demineralisation cartridges or a reverse osmosis system.
Please contact your authorised service partner for support.
We recommend the use of specic glass racks. These racks hold the glasses in slightly inclined positions – this will

IMPORTANT NOTES
improve the rinse efciency.
To avoid unpleasant smelling glasses, specic chlorine-free detergent for glass washing should be used.
Before washing new glasses the rst time with a commercial glass washer, intensive basic cleaning is mandatory to
reduce the greasy lm which is on most glasses for protection during production. If not, water drainage is impaired and
streaks and spots may remain on glasses.
We recommend carrying out the basic cleaning manually in a sink (using gloves and a brush for cleaning) with a much
higher chemical concentration of detergent (minimum 10 g of detergent per liter).
As continued product improvement is a policy of HOBART, specications are subject to change without notice.

2. TRANSPORTATION, STORAGE AND INSTALLATIONS
2.1. TRANSPORTATION AND STORAGE
Folklift must be used during transportation and storage instead of vertical
loading, pay attention to upturn and prevention of break, moisture and
load. (See the marks on the package).
2.2. LOCATION
– Rear wall clearance not required.
– Level machine by turning the feet.
– Distribute machine weight equally onto all feet
2.3. ELECTRICAL CONNECTION
Must be carried out by an authorized technician according to
the local and national codes.
– The electrical supply shall comply with the name-plate data.
– Line fuses and cable cross section shall comply with the
requirements.
NOTE: The machine with or without interlock function has different
working current. Please refer to the wiring diagram.
NOTE: A cut-off device shall be provided to connect the supply cord
(isolating switch or accessible plug device).According to EN
60 335 the appliance must be connected to an equipotential
conductor. The connecting screw ( ) is located beside the
cable inlet.

2.4. WATER CONNECTION
Must be carried out by an authorized technician according to
the national and local codes.
The machine must be operated with potable water. For water
with an extremely high mineral content an external demineralisation is strongly recommended
– Connect to warm water, if possible (max. 65°C).
– Water hardness:
• Machines without softener: max. 3.75° Clark = 0.5 mmol/l.
• Machines with softener: max. 37.5° Clark = 5.3 mmol/l.
– Line ow pressure
Line ow pressure 0,5 – 6 bar.
> 6 bar: pressure reducer valve necessary.
– Connect the union nut “A” (3/4”) of the water supply hose to the
site shut off valve.
– Do not kink or cut the supply hose. If an extended supply hose is
required, use one of the same specications as the original.
NOTE: The water hardness should be ≤0.5mmol/L. If not, water
softener is strongly recommended. Or else, may affect the
warranty set out in the standard conditions of sale.
2.5. DRAIN CONNECTION
Machine without drain pump
– Ensure gravity drain.
– For these machine types, a oor drain is mandatory as the drain
hose exits the machine at approx. 60 mm above oor level. Otherwise, residual water may remain in the tank and hose.
– Do not kink drain hose.
Machine with drain pump
– Connection between machine and site drain must not exceed max.
height of 0,65 m.
– Do not place the drain hose loosely on the oor (the hose could be
rubbed through). Fix it at site!.
– Do not kink drain hose
A
max. 60 mm
max. 0.65 m
