3.Installation
3.1Electrical Connection
The machines will be supplied as standard with cable H07RN-F 5G 2.5 mm2 (cable length approx. 2.5 m
from cable gland).
The supply cord must be connected via a cut-off device (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.
3.2Water Connection
The machines must be operated with potable water.
For water with an extremely high mineral content an external demineralisation is strongly
recommended.
Ideal conductivity value for washware made of stainless steel 80 μS/cm, for glasses 100 µS/cm and for
dishes 200 to 400 μS/cm
Machines without softener:
The machine should be connected to soft and if possible warm water (up to 3 °dh = 0.5 mmol/l, max. 60°C).
Machines with softener:
The machine should be connected to warm water if possible (max. 60°C).
Softener has to be adjusted according to water hardness.
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 bars 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. Eventually needed extension has to be provided with a suitable pressure hose (e.g. 324088-1).
3.3Drain Connection
Connection between machine and site
drain must not exceed the specified height
of max. 0.75 m.
max. 750 mm
Do not kink the drain hose.
Do not place the drain hose loosely on the
floor (the hose could be rubbed through).
Fix it at site!

7.Filling
7.1Airgap
The reed-switch S2 on the small PCB 775540-1 is actuated by the impeller magnet.
The impeller monitors the incoming water flow by counting impulses and then relaying that information back
to the main PCB. The count rate is 200 impulses per litre.
1. Water consumption counter [C77] + [C78] (counted litres are added to basic value "0").
2. Remaining water quantity counter for external water treatment [C79] + [C80] + [S18] (counted litres are subtracted from preset value). See also chap. 12.3, page 33.
Maintenance – To be checked:
Whether leaking water from the airgap overflow (see figure1)) enters the wash tank chamber (visual inspection). If so, the leaking water quantity must not exceed 100 ml per fill step.
Whether the impeller sensor works. This can be carried out in two ways.
1. Service Menu: Select input S2 and activate the fill valve by pushing the ON/OFF button
(--0 / --1 will be displayed alternately). See also chap. 12.1.2, page 29.
2. Visual check: quick flashing LED on main board (see page 31).

Due to the physical properties of rinse aid (e.g. wetting), even smallest rinse aid quantities inside the hose
will be detected by the deficiency sensor. If the sensor is adjusted too sensitively, maybe deficiency will not
be released.
– Test "Deficiency"
Flush the suction hose thoroughly with fresh water to remove any chemicals.
When the hose is drained, the respective LED should be "OFF".
– Test "Full"
Fill the suction hose (see chapter 5, page 8). The respective LED should light up. If not, adjust potentiometer until the LED lights up.
Now the hose should be completely filled and without air bubbles.
TESTING THE PCB
– Select Service Mode (see chapter 12.1.2, page 29).
– Hoses are empty and deficiency sensor potentiometers turned to left stop:
Switching functions "S07" (detergent) and "S08" (rinse aid) must be "0". No sensor LED lights up.
– Potentiometers turned to right stop:
Switching functions "S07" (detergent) and "S08" (rinse aid) must be "1". The LED of the respective circuit lights up.
Detergent deficiency indication "- - 0"
Rinse aid hose filled "- - 1"
– After testing: Set potentiometers (detergent and rinse aid) to value "3" (based on tests with the most common products).

7.4.2 Softener Check Procedure
Check:
Parameter [C84] = number of salt fillings.
Parameter [C85] = number of wash cycles with deficiency of salt (illuminated salt indicator).
What you need to verify the softener function:
1. Test kit to measure the water hardness (part number 607236). Pay attention to expiry-date.
2. A conductivity-meter (possibly pH indicator strips 609927).
How respectively where to measure?
Use clean tea-cup or beaker for sampling water.
1. Take measurement of the total water hardness (°dh) at the tap where the machine is connected to.
2. Measure the conductivity (μS/cm) at the tap where the machine is connected to.
3. Measure the hardness of the water in the booster.
Therefore, the booster drain hose is to be used. Discard the first cup of water to ensure that no residuals
from the hose falsifies the measured value.
4. Measure the conductivity of the booster water.
Adjustment of softener setting according to the hardness of incoming water:
1. Ensure adequate softener setting:
H01 = up to 7°dh / H02 = 8 to 14°dh / H03 = 15 to 21°dh / H04 = 22 to 30°dh.
2. Ensure that the salt chamber contains salt.
3. Ensure that granular salt is used (salt tablets are not allowed).
4. Ensure that the salt chamber has been filled up with water.
Approximate values if softener function is O.K.:
The conductivity of the booster water shall be about 300μS/cm higher than the conductivity of that water
taken at the tap.
For example: If the total hardness of the incoming water is 500μS/cm, the conductivity of the booster water
will be roughly 800μS/cm. If this value is significantly higher (e.g. 3000 μS/cm), an incorrect softener function is very likely.
Further steps:
1. Adjust the softener to "H04" to ensure a new regeneration will be actuated every 3 cycles.
2. Select the shortest program “P01” and take a sample of water (a tea-cup) at the booster drain hose immediately after the program cycle has ceased.
3. Measure and note down the water hardness.
4. Measure and note down the conductivity.
Repeat procedures 1 to 4 seven times to ensure salting of both resin columns.
An incorrect softener function is most supposable if the measured hardness at the booster drain hose is
higher than 5°dh and / or the conductivity is extremely high (i. e. in the range of 3000 μS/cm).
Proceed as following in case of too high hardness and / or conductivity values:
1. Run the drain cycle to ensure booster emptying down to the pump intake.
2. Remove the side panels.
3. Activate the softener test program "U03" as described on next page.
Observe the resin columns with the aid of a torch from the left hand side of the machine. (Column "A" is at the left, column "B" is at the right from this point of view).
If the sequential operation deviates from the described one (see next page), i. e. resin "B" was six times activated, it is very likely that a softener valve is jamming or the electrical connections are interchanged
(this is less probable).
The booster must be flushed thoroughly at the end of this procedure (run 5 wash cycles) to ensure the chloride content is at an acceptable level to prevent corrosion.
Never run the softener test program at the begin of the herein described procedure because it is
unavoidable that salt will be flushed into the system. Thus, measurements would become incorrect.

8.Washing
8.1Wash Pump and Strainer System
The pump unit includes motor with flange, mechanical shaft seal, impeller and capacitor (AMX only).
A non return flap (called Flipper) allows the draining of the circulation system.
The Flipper prevents soil, collected in the pump sump, from reentering the circulating system.
8.1.1Function:
During wash cycle, the wash liquid is distributed to the upper and lower wash arm. The back flowing wash
liquid is passing a strainer system, the integrated intake strainer and enters the wash pump from the outer
annular space of the suction unit via the main duct.
Drain system: Used for partial draining of the soiled wash liquid (Genius X2) during wash cycle (approx. 20 seconds after program start) or for the complete draining of the wash tank. Pressure-side the soiled
wash liquid will enter the drain via hose system and ventilation valve.
During draining or self-cleaning cycle the flipper is open.
Sectional drawing Genius X2

Cleaning
9.1Hygiene Cleaning (AUP models only)
After reaching a pre-set number of wash cycles (parameter [C71] = 2500) the Hygiene indicator "HYG"
lights up to indicate that an automatic hygiene cleaning of the machine interior should be carried out.
Procedure
– Before end of operation: Take out rack and remove manually coarse soil from tank strainer
– Put two HOBART-Hygiene-Cleaner Tabs1) into the machine interior.
– Push Program button repeatedly until the upper Display shows "H".
– Close the hood.
During the Hygiene program is running (duration approx. 20 minutes) the green illuminated segments go out one after the other.
At the end of the cycle the machine switches off automatically.
If necessary hygiene cleaning should be carried out before reaching the pre-set number of wash cycles.
With regular use the machine interior will remain free of food debris and deposits.

part number 897954 = box with 15 Tabs.
Functional description
– Switching function [S19] has to be activated "1" (with AUP automatically).
– Machine ON and hood closed.
– Hygiene cleaning "H" selected.
When the ON/OFF button is pressed, the tank will be completely drained. Simultaneously the standard filling program (booster filling, booster heating, rinse pump, etc.) will be started, without pre-dosing of detergent / rinse aid.
If tank level is reached, the wash pump will be started (approx. 5 minutes) to circulate the tank water.
When wash cycle is completed, the self cleaning program will be started.
After the Hygiene program has ceased, the control switches off and parameter [C71] will be reset to the
adjusted wash cycle number.
Maintenance
Via parameter [C72] you can check the number of completed hygiene cycles (see also page 33).

12.3 Counter Functions
Request for hygiene program [C71] – down-counter
The number of wash cycles will be subtracted from the preset value ([S19] "on").
When "0" is reached, start of hygiene program is requested.
After hygiene cleaning is completed, this counter will be reset to basic value.
Number of hygiene cycles [C72] – up-counter / basic value "0"
The number of completed hygiene cycles is counted.
Reset only possible via basic data.
Note: Control, how often the program has been started.
Number of wash cycles [C73] + [C74] – up-counter / basic value "0"
The number of wash cycles will be counted.
Example 1420 cycles: [C73] = 420 / [C74] = 1
Note: Readout and note down in the report.
Service interval [C75] + [C76] – down-counter
The number of wash cycles will be subtracted from the preset value ([S17] "on").
When [C75] + [C76] is "0", the service indicator illuminates.
Reset only possible via basic data.
Note: Of interest in case of service contract.
Water consumption [C77] + [C78] – up-counter / basic value "0"
After 200 input pulses of S2 (= 1 litre water flow), the counter value will be increased by 1.
Input pulses below 200 are buffered and counting will continue with the next input pulses.
Reset only possible via basic data.
Note: The customer can readout the actual water consumption (see page 8 "customer menu").
Remaining water quantity (external water treatment) [C79] + [C80] + [S18] – down-counter
This function will be programmed via service mode U02 (see page 28).
[S18]
= activation
[C79]+[C80] = water treatment capacity (liter). Possible settings are [C79] 0-999, [C80] 0-999 x 1000.
Example 5500 litres: [C79] = 500 / [C80] = 5
After 200 input pulses of S2 (= 1 litre water flow), the counter value will be decreased by 1.
Input pulses below 200 are buffered and counting will continue with the next input pulses.
When "0" is reached, "d 0" will be displayed.
Reset to pre-set value via customer menu by pushing the ON/OFF button (see page 8).
Note: The actual value can be checked via customer menu (indication for next replacement of external
demineralisation cartridge for example).
Number of salt fillings – deficiency of salt [C84] – up-counter
The number of "salt indicator switch-on" will be counted.
Note: With this parameter you can check how often the softener has been refilled.
Wash cycles with deficiency of salt [C85] – up-counter
The number of started wash cycles in spite of salt deficiency (illuminated salt indicator) will be counted.
Note: Maybe an evidence in the case of calcified machine or heating elements for example.
NOTE:
Starting from E-EPROM rev. 3.0, the actual counter readings keep unchanged after software update
as well as settings of detergent and rinse aid dispensers (rev. 3.9).
Reset of all counters can be carried out via menue option rES in Service Menu (see also page 29).
