CONTENTS PageIMPORTANT 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 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 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).

1. INSTALLATION
1.1. LOCATION
– Rear wall clearance not required.
– Level machine by turning the feet.
– Distribute machine weight equally onto all feet
1.2. 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.
– Line fuses and cable cross section shall comply with the require-
ments.
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.
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).
– 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
• Ecomax 402/502-20:
Line ow pressure 0,5 – 10 bar.
> 10 bar: pressure reducer valve necessary.
• Sonstige Modelle:
Line ow pressure:2 – 6 bar.
< 2 bar: provide a rinse pumpe at site.
> 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.
1.4. 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.
Maschine mit Ablaufpumpe:
– Die Verbindung zwischen Maschine und bauseitigem Ablauf darf die
maximale Höhe von 0,65 m nicht übersteigen.
– Den Ablaufschlauch nicht lose auf den Fußboden legen (der
Schlauch könnte durchgescheuert werden), sondern bauseits
xieren.
– Ablaufschlauch nicht knicken.

2. CONTROLS
➀
Machine ON/STOP button Pushing this button switches the machine on.
The LED lights up
− ashing = Machine is lling and heating.
− permanent = Maschine ist betriebsberei
In case of operating error or faults, it is possible to switch-off the machine immediately without the drain cycle, by pushing this button.
After switch off, the machine is not voltage free!
➁
Program buttons By pushing these buttons, it is possible to select between short cycle (1) and
standard cycle (2).
The appropriate LED lights up.
➂
Drain/OFF button By pushing and holding (3 seconds) this button, the self-cleaning cycle starts.
At the end of the cycle, the machine switches off automatically. Machines with
optional drain pump will drain the tank automatically.
After switch off, the machine is not voltage free!

3. START-UP
Attention:
The maximum suction head of the dosing pumps is 1.5 m. Do
not confuse the containers
Use only detergent and rinse aid for commercial applications.
Please pay attention to the manufacturer’s safety instructions.
NOTE: 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 section
3.3.). Otherwise, the mixing of different types of chemicals
will cause crystallization, which may result in a malfunction
of the dosing pump.
3.1. DETERGENT
– Do not use any acidic detergent products with the optional 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 section 3.3..
3.2. RINSE AID
– Place the suction hose (blue marking) into the external rinse aid
container. Fill the suction hose according to chapter section 3.3.
