THE MANUFACTURER OF THE MACHINE IS NOT RESPONSIBLE FOR THE DAMAGE OF HEATING
ELEMENTS AND OTHER MACHINE PARTS DUE TO CALCIUM SEDIMENTS.
DO NOT OPERATE THE MACHINE WITH BROKEN / MISSING PARTS OR OPENED COVERS!
BEFORE A MAINTENANCE WORK DISCONNECT THE MACHINE POWER SUPPLY !
WHEN THE MAIN SWITCH IS IN „OFF" POSITION THE INLET TERMINALS OF THE MACHINE MAIN
SWITCH ARE STILL UNDER CURRENT!
THAT IS THE WAY TO AVOID INJURIES.
ALWAYS PUT ALL MACHINE COVERS BACK TO THEIR PLACES AFTER THE MAINTENANCE IS FINISHED.
When replacing any parts of the machine, exchange them with original parts obtained from your dealer or ordered

5.1. INTRODUCTION

Due to the quality construction and reliable parts and materials of the machine the preventive maintenance
has been limited to the minimum.
When the machine is still under warranty, call your dealer's service to perform the interference stated in chapter
(5.3. - 5.5) to avoid the warranty cancellation.
The technical service of your dealer is ready to eliminate serious failures of your machine.

5.2. DAILY

Check daily:
1. Water, air and possible steam inlets for leakage.
2. Check and clean an air separator of dirt as needed.
3. Drain valve for leakage during a washing process and for its proper opening (the valve is in open position
when the main switch is ON, when air pressure is sufficient and pneumatic solenoid valve DV1 is without
electric current).
4. Clean surface machine parts to remove any traces of washing soaps.
5. Hoppers must be cleaned at the end of each working day. Remove sediments from inside of the reservoir
by means of a plastic spatula and splash by water.
6. Clean up the door gaskets to remove sediments and dirt.
Do not use solvents or acids to clean the rubber door gasket !
After the machine has been cleaned up, leave the door opened to provide the machine venting and to prolong
the door gasket life service. After work, we recommend to shut off all main inlets of water, electric power,
possibly steam. We mean the laundry main valves, not individual machine valves.
