IMPORTANT NOTES
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.
MACHINE NOISE LEVEL:
The machine noise level is < 70 dB (A).
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 may cause spots and streaks results during the drying process. Minerals which are dissolved in
the water become visible during the drying process in the form of spots and streaks.
Authorised HOBART 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 specific
demineralisation cartridges or a reverse osmosis system.
Just contact your authorised HOBART partner for support.
We recommend the use of specific HOBART glass racks. Hobart racks hold the glasses in slightly
inclined positions – this will improve the rinse efficiency.
To avoid unpleasant smelling glasses, specific chlorine-free detergent for glass washing should be
used.
Before washing new glasses the first time with a commercial glass washer, intensive basic cleaning
is mandatory to reduce the greasy film which is on most glasses for protection during production.
The basic cleaning needs to be done with a much higher chemical concentration of detergent (minimum 10 g of detergent per liter). We recommend carrying out the basic cleaning manually in a sink
(using gloves and a brush for cleaning).

1. INSTALLATION
1.1. LOCATION
– Wall clearance is not required.
– Level machine by turning the feet.
– Distribute machine weight equally onto all feet.
NOTE: Vapor may escape from the dishwasher door. Therefore, adja-
cent furniture has to be protected to prevent swelling.
1.2. ELECTRICAL CONNECTION
Must be carried out by an authorized technician according to
the local and national codes.
For Australia: in accordance with AS/NZS3500.1
– The electrical supply shall comply with the name-plate data.
– Adaptation to an alternative electrical supply is achievable as per
wiring diagram. Respective schemata are adjacent to the connection terminal.
– Line fuses and cable cross section shall comply with the require-
ments.
– A cut-off device shall be provided to connect the supply cord (isolat-
ing switch or accessible plug device).
NOTE: According to EN 60 335 the appliance must be connected to
an equipotential conductor. The connecting screw (
) is lo-
cated beside the cable inlet.

1.3. 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. 60°C).
– For use of switchable cold water rinse, connect to cold water, if
possible (max. 20°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 flow pressure 0.5 – 10 bar
• If the line flow pressure is above 10 bar, provide pressure
reducer at source.
– 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 specifi-
cations as the original.
1.4. Drain ConneCtion
– Connection between machine and site drain must not exceed max.
height of 0.75 m (GXH: 0.6 m).
– Do not kink the drain hose.
