Inlet valves 1“ (machine 22 kg / 50 lbs capacity: 3/4“) for cold and hot water are delivered with the machine. For these valves use inlet pressure hoses with gaskets. Mount shut - off valves 1“ (machine 22 kg / 50 lbs capacity: 3/4“) to the water supply pipes, it will make the maintenance and cleaning of filters delivered with a machine easy.
ELECTRICAL CONNECTION The machine has been designed for connecting to the electrical network according the specification of your order. Before connection check the voltage values and the frequency stated in the machine label (fig.3.5, pos.12), if they correspond to your power network. The way of the connection is described in fig. 4.4.A.
PROTECTION WITH EARTH LEAKAGE TRIPS To increase the safety of the operating personnel and / or servicemen during the maintenance work and operation with electric devices it is recommended to mount in front of the supply cable in the laundry switchboard an earth leakage trip according to fig. 4.4.A, preferably with an actuating current 30 mA. The main contacts of the earth leakage trip must comply with the specified power input of the machine.
CONNECTING POINT The cable can be attached to the machine from a cable channel (from below). If the cable is attached from above, it is recommended to make a sag on the cable in front of the entry into the cable bushing (fig.4.4.C, pos.4). In this way an ingress of condensed water into the bushing or the machine can be avoided. When the cable is pushed through the bushing (2), tighten the sealing nut of the bushing.
CONNECTION TO LIQUID SOAP SUPPLY SYSTEM It is possible to connect external liquid soap supply system to the machine. Connect the hoses of liquid soap supplies on inlets of dosing pumps. Connect outlets on vertical inlets of external liquid soap mixer (fig.4.4.E, pos.2). After removing the black plug, put the hose of external liquid soap dosing (7), coming from the mixer, through the hole in the machine rear side (6). Provide the opening, where the hose is coming through, with rubber bushing (5).
and pass it in the appropriate opening in the machine. Connect these signal terminals like the manufacturer of the liquid soap system requires. The liquid soap system may draw maximum 0,1A out the control circuit of the washer-extractor. WATER RECYCLED DRAINAGE CONNECTION Valid only for machines equipped with recycled drainage by the manufacturer or for machines after modification. Attach connecting hoses to the discharging valve of 76 mm / 3“ diameter, located on the right side (from rear view).
5. MAINTENANCE WARNING ! ! ALWAYS FOLLOW SAFETY INSTRUCTIONS! DO NOT BYPASS ANY SAFETY DEVICES OR THEIR PARTS. ANY INTERFERENCE TO THE MACHINE FUNCTIONS AND CONSTRUCTION ARE PROHIBITED! USE THE PROPER CHEMICAL AGENTS WHICH AVOID CALCIUM SEDIMENTS ON HEATING ELEMENTS AND OTHER MACHINE PARTS. DISCUSS THIS ISSUE WITH YOUR SUPPLIER OF WASHING PRODUCTS. THE MANUFACTURER OF THE MACHINE IS NOT RESPONSIBLE FOR THE DAMAGE OF HEATING ELEMENTS AND OTHER MACHINE PARTS DUE TO CALCIUM SEDIMENTS.
! BEFORE REMOVING TOP OR BACK PANEL OF THE MACHINE, SWITCH POWER OFF AND WAIT FOR AT LEAST 10 MINUTES. BEFORE STARTING INSPECTION OF FREQUENCY INVERTER, CHECK FOR RESIDUAL VOLTAGE ACROSS MAIN CIRCUIT TERMINALS + AND -. THIS VOLTAGE MUST BE BELOW 30VDC BEFORE YOU CAN ACCESS THE INVERTER FOR INSPECTION. 3.

TIGHTENING MOMENTS WARNING ! ! REGULARLY, ONCE IN THREE MONTHS OR EVERY 500 WORKING HOURS (WHICH EVER COMES FIRST) INSPECT THE TIGHTNESS OF THE BOLTS ! If anyone of the bolts has been damaged, exchange it with the bolt of the same strength value marked on its head.
MARKING OF THE BOLTS A Bolts of hub flange B Bolts fixing the rear wall of external drum to the inner drum covering over a tyre C Bolts fixing the plate of motors to the outer face D Bolts fixing the external drum to the front face E Bolts fixing the support and damper holders to the rear wall of outer drum F Bolts fixing the plate of motors to the damper holders G Housing fixing the drum pulley to the shaft Tightening Moments values of bolts and nuts for 33/40/55 kg 80/100/125 lbs machines (fig. 5.7.
Every time you use a grease gun especially for greasing bearings and seals, do it slowly - not faster than 5 strokes in 1 minute. The grease gun can create a high pressure which would cause the seal deformation and consequent leakage. Never operate the grease gun faster even if the grease contain air gaps. Overlubrication can cause the same damage as an insufficient lubrication. Always make sure that your grease gun is in perfect condition.
BELT REPLACEMENT NEVER USE A CROWBAR TO TAKE OFF THE BELTS OVER THE PULLEY GROOVES. Loosen the bolts of tightening pulley on the drum rear wall and the adjusting screw for taking the belts off. TWO - MOTOR VERSION: Belts between motor for washing and motor for extracting are to be removed after loosing the bolts that fasten the motor for extracting and after loosing the tightening bolts. Always change a complete set of the belts for one transmission.
ADJUSTING ON THE SIDE OF THE DOOR HANDLE ONLY FOR MACHINE 33/40/55 kg 80/100/125 lbs 1. Unscrew the bolt (fig. 5.11.B, detail „B“, pos. 1) securing the casing of the door handle (2). 2. Unscrew the casing (2) from the door bearer (3) always by a whole turn that the groove in the casing thread (2) appears bellow the securing bolt (1). 3. To make the casing turning (2) easier, use the semicircle notches (4) between the casing (2) and the handle pin (5), in which you insert cylindrical object (a bolt etc.).
If the thrust adjusting has not been sufficient, exchange the door seal. 5.12. SPRING UNIT Spring units (fig.5.12., pos.1) are to be adjusted in the case that you found out the suspended machine part is not in a horizontal position (without linen and water) or after the spring unit has been replaced. ! WARNING ! MAIN SWITCH MUST BE OFF! The spring unit adjusting is achieved by turning the nuts (2) with the same number of turns always simultaneously on the opposite guiding rods (3) of spring unit.

EARTH LEAKAGE TRIPS If the laundry is equipped with the earth leakage trip in the inlet circuit of the electric switchboard it is necessary to test it regularly.
6. TROUBLE SHOOTING AIDS 6.1. DOOR BLOCKING DESCRIPTION OF DOOR LOCK FUNCTION The door lock has been designed as a compact unit. Its function is to secure the door against opening during the washing cycle. Unlocking after a cycle completion will be made by: a signal from the programmer (microprocessor version) a manual pressing of the lock push button (card version) The lock has been blocked also during the failure situations e.g.

The inlet valve filter clogged: WARNING ! ! STOP THE HOT WATER INLET TO THE MACHINE AND WAIT FOR COMPONENTS TO COOL DOWN! shut the main water inlet, take off the inlet valve filters, clean and put them back. A damaged hose: -replace the hose or its gasket. Defective inlet valve: -change the valve.
6.4. TOO LONG DRAINAGE TIME Clogged drainage: -clean the outlet. Defected drainage valve: -clean the drainage valve or exchange it. Too small waste sump dimensions: -check the waste sump diameters and enlarge it accordingly. 6.5.
