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 a­ ppliances.
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 remain on the glasses and become visible 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). Alternatively, the program described in section 7. can also be
used.
