WATER CONNECTION AND RETROFITTING OF A DETERGENT DISPENSER

WATER CONNECTION:

1 Machines without softener or without cold rinse:The dishwasher should be connected to soft and if possible warm water( 0-4° Clark = 0-0,534mmol/l – max. 60°C ).

2 Machines with softener:The dishwasher should be connected to warm water (max. 60°C)if possible.

3 Line flow pressure: min 0,5 bar, max 10 bar.If 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. Eventually needed extension has to beprovided with a suitable pressure hose, e.g. 324088-1.

4 For water with an extremely high mineral content, water treatment isrecommended. (Not for machines with built-in softener.)

5 Drain connection:Connection between machine and site drain must not exeed maximumheight of 800 mm. Do not kink the drain hose.All machines are provided with a drain pump.

CONNECTING OF DETERGENT PUMPIf no detergent pump was ordered, please connect the detergent dispenser as described below.

– Tank must be drained.– Switch off main switch or unplug.– Liquid detergent dispenser: remove front panel.

Powder or solid detergent dispenser: remove front panel and the left or right hand side panel (according torequirement on site).

– Lift up control box and turn it to front.

TO CONNECT A LIQUID DETERGENT DISPENSER:A Remove blanking plug (AMXXT/AUXXT at the right tank) and install detergent inlet fitting + gasket.B Connect a hose (PVC / 6mm outside Ø x 4mm inside Ø) between outlet of the detergent pump and the

detergent inlet of the wash tank. Tighten with hose clamp.C Install dosage pump or fit external dispenser.

TO CONNECT A POWDER OR SOLID DETERGENTDISPENSER:

D Break out perforated disk at the tank panel (either atthe right or left side)

E Drill a hole through the inner tank wall appropriate tothe required connection diameter.Screw up tightly the dosing connection with tank wall.

WHAT IS NEW ?

GeneralThere are only four buttons on the keybord: "drain", "ON/OFF", "program"and "start".

AMX/AMXX/AUXX: The control unit is now inside the top panel installed (slopedfront) and via cable (on the back side of the machine) connected to the PCB.

AMXXT/AUXXT: The control unit is installed inside the lower front panel

The reed switch 775491-1 is identical with the FX/GX switch,the magnet is fitted inside the top panel.

Fill valve:The fill valve (5l/min) is part of the supply hose and is connected to the control.Filling is no longer controlled by pressure switch B3, a specific impeller integratedin the air gap is controlling the process (200 impulses mean 1 litre).The fill program is only terminated when the pressure switch B4/II (S4) closes(approx. eight fill cycles).

Control:The control 897502-1 is completely new. There is a separate fuse 775570-1for the control circuit (500V 6,3A T 6,3x32).

All settings can be done now by shortcuts, i.e. no manipulator is needed tochange values.

Location of terminals and the contactor:The terminals and the booster contactor are located inside a hinged control box.

Wash pump and rinse pump:The wash pump has an integrated self resetting thermal cut-out.There is no wash pump contactor anymore at the AMX 900.

Temperature sensors and tank heating:A temperature sensor (NTC - already used with the new FX) is integral part of theupper booster heating element (exchangeable).

The conventional tank heating element is replaced by a heater mat (0,5kW or 0,6kW)which is attached to the exterior wall of the wash tank. The heater mat has an integraltemperature limiter, tripping at 167,5°C (tripping does destroy the element).

The tank heating is now controlled by the second level of the pressure switch.The air chamber is now mounted at the right side of the wash tank.

Detergent and rinse aid dispenser:Now using peristaltic pumps (such as FX/GX).Detergent will be dosed as before into the wash tank.Delivery rate detergent: 3.0 l/hDelivery rate rinse aid: 0.4 l/h



1. Machine ON / OFF S2 Pushing this button switches the dishwasher on or off.NOTE: After switch off, the machine is not voltage free!The button illuminates permanently during operation.

2. Temperature Wash (°C) Temperatures (2 and 3) are only displayed when the program key (4) ispushed for minimum 3 seconds. The indicators go out 10 seconds afterreleasing program button.

3. Temperature Rinse (°C) Permanent temperature display can be activated ( set U02 S15 to "1" ).

4. Program button S3 Pushing this button selects different preset wash programs, according to themodel. The program number appears in the rinse temperature display (3).

P 01 = Short cycle (for light / medium soiled dishes and glassware)P 02 = Standard cycle (for medium / heavy soiled dishes)P 03 = Long cycle (for dried on soiling and containers)

P 04 = Endless cycleAn endless cycle will be indicated by moving light points in thetemperature displays (2 and 3). To stop the wash cycle, push Startbutton (5). After 20 minutes the cycle will stop automatically.

5. Start button S4 This button illuminates to indicate the mode of the machine:

RED = machine fills and starts heating; machine type settingGREEN = machine is ready for operation; test program softenerBLUE = selected program is running; modification basic data

AUXX models only: High pressure cleaningBy pushing the blue illuminated Start button for 3 seconds after starting awash cycle, high pressure cleaning will be activated.

6. Not in use yet.

7. Salt This symbol indicates that internal softener requires salt. (Only for machineswith built-in softener.)

8. Service This symbol indicates that the dishwasher has developed a fault (not for FIL).In the rinse temperature display appears a code (see page 18). When theservice counter activates, this symbol illuminates after a preset number ofwash cycles.

9. Drain button S1 To initiate a drain cycle, push and hold this button for minimum 2 seconds.The button illuminates during drain cycle.Once the drain cycle has completed the machine switches off automatically.NOTE: After switch off, the machine is not voltage free!

To reach hygienic rinse temperatures even with cold water connection or reduced heating power, theactual cycle times will be extended accordingly.

FIRST RUN

1. Place the "blue" suction hose into the rinse agent container and the "clear" suction hose into the detergentcontainer. (The chemicals used must be suitable for dish or glass washing. The ph-value of detergent has tobe higher than 7.)

Priming the suction hoses see page 10.

2. For machines with optional built-in softener:Before the first run, the softener has to be filled with salt and water.Open the hood. Unscrew the softener cap and fill the softener with 2 kg of "Granular salt" (do not use salt tablets)and fill up the softener with potable water. Clean seal and rim of softener lid carefully, before closing.There may be a short delay before the Salt indicator light goes out.

Adjustment of water hardness see page 10.

3. FILLING THE RINSE BOOSTER:Filling the rinse booster for the first time. This is necessary after the dishwasher has been first installedor when the booster has been drained (to replace heating elements for instance).

Open the shut-off valve at site.Switch on the electrical supply via the cut-off device or plug.

ADJUSTING WATER HARDNESS (with optional softener only):To adjust the softener to the local water hardness first determine the temporary hardness of the water supply.Carry out a hardness test using a hardness test kit.Push the program button again.The Rinse temperature window displays "K02K02K02K02K02" = adjustment of the softener (if built in).Push the Start button repeatedly, until the required value appears in the rinse temperature window(H01 = up to 12° Clark / H02 = 13 to 25° Clark / H03 = 26 to 37° Clark).

PRIMING OF SUCTION HOSE: DETERGENT (only with built in detergent pump)Close the hood. The rinse temperature display will change from K02K02K02K02K02 the softener setting to SF1SF1SF1SF1SF1 which is thepriming for the detergent hose.To prime the detergent suction hose, push and hold the start button for approx. 1minute (--I--I--I--I--I appears in thewash temperature display).

PRIMING OF SUCTION HOSE: RINSE AGENTOnce the detergent hose has been primed push the program button again and SF2SF2SF2SF2SF2 appears in the rinsetemperature display.To prime the rinse agent suction hose, push and hold the start button for approx. 3 minutes (--I--I--I--I--I appearsin the wash temperature display).Note: When using external dosing equipment with longer suction hoses, push and hold the start-buttonfor approx 6 minutes.

PREVIEWING TEMPERATURES:To view the wash and rinse temperatures push and hold the program button until the actual wash and rinsetemperatures (°C) will be displayed in their respective windows. The temperatures will go out after 10 secondsonce the program button is released.Temperatures can be displayed permanently in their respective windows by altering S15 in configuration mode(see page 20).

Faults:The service symbol illuminates and in the rinse temperature display a code appears.Possible codes: FIL, AL, UL, F01, F02, HEI (see also page 18).

THE SETTING PROCEDURE CAN BE INTERRUPTED AT ANY TIME BY CLOSING THE HOOD.
