    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

    ( 0-3dh = 0-0,534mmol/l max. 60

    C ).

    2 Machines with softener:The dishwasher should be connected to warm water (max. 60C)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 x 4mm inside ) 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.

    Connect the plug of the wire harness with the dosage pump (max. 100 VA).

    Close control box and put panel(s) back into place. Switch on main switch at site or put the plug in.

    COMPONENTS

    General

    There 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 installed at the rear of the machine,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(AMX approx. 9 fill cycles / AMXX/AUXX approx. 12 fill cycles).

    Control:

    There is a separate fuse 775570-1 for 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.

    Temperature sensors and tank heating:

    A temperature sensor 775612-1 (NTC) is integral part of theupper booster heating element (exchangeable).

    The conventional tank heating element is replaced by a heater mat (0,5kW)which is attached to the exterior wall of the wash tank. The heater mat hasan integral temperature limiter, tripping at 167.5C (tripping does destroy the element).

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

    AMXX / AUXX(L) models only*:

    An additional vacuum switch is installed to prevent negativetank pressure when wash tank filters are blocked(indicated by flashing blue/red start button).

    *AMXX / AUXX starting with serial no 8632 2800.

    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
