1 IMPORTANT NOTES
Use in Accordance with Regulations
This machine is exclusively to be used to wash glasses.
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 60 dB (A).
Connecting tensions:
The machine described with this operation manual, has following connecting tensions:
230 V/50 Hz/1 Ph/N/PE or 400 V/50 Hz/3 Ph/N/PE
BASICS REGARDING GLASSWASHING
Water quality and impact on the cleaning result:
The local supply water quality has a major impact on the wash and rinse result:
A high content of minerals may cause streaky 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 service personnel can determine the content of minerals by measuring the electrical conductivity.
Values of less than 100 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 service partner for support.
Other important requirements:
We recommend to use specific HOBART glass racks. Hobart racks hold the glasses in slightly inclined
positions – this will improve the rinse efficiency.
To avoid unpleasant smelling glasses, you should use specific chlorine-free detergent for glasswashing.
Before washing new glasses the first time with a commercial glasswasher, it is necessary to carry out an
intensive basic cleaning 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 to carry out the basic cleaning manually in a sink (using gloves and a
brush for cleaning).

2.1 LOCATION
Wall clearence is not required.
Level machine by turning the feet.
Distribute machine weight equally onto all feet.
Vapour may escape from the glasswasher door. Therefore adjacent
furniture has to be protected to prevent swelling.
2.2 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.
Adaptation to an alternative electrical supply is achievable as per
wiring diagram.
Line fuses and cable cross section shall comply with the requirements.
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.
2.3 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.
The conductivity value should not exceed 100 µS/cm.
For water with an extremely high mineral content an external
demineralisation is strongly recommended.
Machines without softener: Connect to soft and if possible warm
water (up to 4° Clark = 0.5 mmol/l, max. 60°C).
Machines with softener: Connect to warm water if possible
(max. 37.5° Clark = 5.3 mmol/l, max. 60°C) if possible.
Line flow pressure 0.5 – 10 bar.
Important: the line flow pressure must not be less than 0.5 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 specifications as the original.
2.4 DRAIN CONNECTION
Connection between machine and site drain must not exceed the
specified height.
Machines without Softener: max. 1.0 m
Machines with Softener: max. 0.6 m
Do not kink the drain hose.

4.1 DETERGENT / RINSE AID
Use only commercial detergent and rinse aid. Please pay attention to
the manufacturers safety instructions.
Before changing to a different product type (even from the same
supplier), the suction hoses must be rinsed thoroughly with fresh
water (procedure as described under 4.4).
Otherwise, the mixing of different types of chemicals will cause
crystallisation, which may result in a malfunction of the dosing pump.
The dosing pumps can operate to a maximum head height of 1.5 m. Do not confuse the containers !
4.1.1 DETERGENT
Do not use any acidic detergent products with the built-in
detergent pump! (The ph-value has to be higher than 7.)
Place the suction hose into the external detergent container.
Fill the suction hose according to chapter 4.4.
4.1.2 RINSE AID
Place the suction hose (blue marking) into the external rinse aid
container. Fill the suction hose according to chapter 4.4.
4.2 SOFTENER (only on option)
For the first run, the softener has to be filled with regeneration salt
and potable water.
Filling the salt reservoir with cleaning agent will damage the water softener.
Open the door.
Unscrew the softener lid and fill the softener with 1.5 kg of "Granular
regeneration salt" (do not use salt tablets).
Fill up the softener with potable water.
Clean seal and rim of softener lid carefully, before closing the lid.
Close lid and tighten.
In order to prevent corrosion it is necessary to remove any
salt residues from tank bottom.
4.3 INITIAL BOOSTER FILL
Close the door.
Open shut-off valve.
Switch on main switch or put the plug in.
Push the ON/OFF button ➀.
At the temperature indicator Rinse ➅appears "boF" and flashes.
The rinse booster heater has to be filled as described in the following text.
Push the ON/OFF button ➀again, to switch off the machine.
Open the door, push Program button ➃and Drain button ➂
simultaneously until at the temperature indicator Rinse ➅appears
again "boF".

13 TROUBLESHOOTING GUIDE
TYPE OF FAILURE POSSIBLE CAUSE REMEDY
Poor wash result
Glasses are not clean. Wash arms stiff (you should be able to
turn them easily by hand).
Take out wash arms and clean them thoroughly.
Check water outlet from machine to wash arms is
clear.
Wash nozzles are clogged
(visual check).
Take out wash arms and rinse thoroughly until soil is
removed.
Replace correctly.
Rinse nozzles are clogged (possibly by
lime deposit)
Take out wash arms and decalcify them in separate
container.
Detergent concentration is too low or too
high.
Check setting of detergent concentration.
See also operating instructions point 9.1.
Coarse strainer soiled. Take out strainer, empty and clean it.
Wrong program selected for heavily
soiled glasses.
Select program with longer wash cycle.
Glasses do not dry properly. Rinse aid concentration too low. Increase concentration.
See also operating instructions point 9.2.
Rack is not suitable for type of glasses
(sloping).
Use appropriate racks to create a sloping position
which allows water to drain away from cavities.
Glasses stay too long in the machine at
the end of program.
Take out glasses as soon as cycle is completed to
enable them to dry.
12 FAULTS

TROUBLESHOOTING GUIDE
TYPE OF FAILURE POSSIBLE CAUSE REMEDY
Poor wash result
Stripes and staines on
glasses.
Rinse aid concentration too high. Reduce quantity (see instructions).
Hard water or high mineral content. Check water quality.
Obtain details from local water authority.
Recommended values:
Ideal degree of hardness is up to 4° Clark.
Ideal conductivity value is max. 100 µS/cm.
Rack is not suitable for type of glasses
(sloping).
Use appropriate racks to create a sloping position
which allows water to drain away from cavities.
Insufficient rinse aid concentration
causes staines.
Increase quantity (see instructions).
Machine with softener:
wrong type of salt used. Use only granular regeneration salt.
Other malfunctions
Glasses are totally or
partially cloudy.
Surface of glasses is rough and porous,
this is called glass corrosion.
This is not caused by a malfunction on the machine.
Replace with new glasses.
Glass breakages. Use of inappropriate glass racks. Use appropriate racks.
Machine suddenly stops
during wash program.
Machine is connected to a "maximum
power supply unit" which cuts out the
energy consumer at a given point, or
machine is interlocked with another
energy consumer unit.
Connect machine separately (call electrician).
Blown site fuse. Check site fuses.

The manufacturer retains the right at all products changes or improvements without announcement.
