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.
DO NOT OPERATE THE MACHINE WITH BROKEN / MISSING PARTS OR OPENED COVERS!
BEFORE MAINTENANCE WORK DISCONNECT THE MACHINE POWER SUPPLY!
WHEN THE MAIN SWITCH IS TURNED OFF THE INLET TERMINALS OF THE MACHINE MAIN SWITCH
ARE STILL UNDER CURRENT! THAT IS THE WAY TO AVOID INJURIES.
When replacing any parts of the machine, exchange them with original parts obtained from your dealer or ordered
through the spare parts manual!
5.1. INTRODUCTION
Preventive maintenance has been reduced to a minimum by the careful design of the machine, and the choice
of reliable components and materials.
5.2. DAILY
CHECK:
•
Water (steam) inlets for leaks
•
Check that the drain valve is not leaking during the washing process, and that it opens properly afterwards
(valve is open without electrical power).
•
The machine should always be clean.
•
Clean upper side and body regularly in order to remove all soap traces.
•
The soap hopper should be cleaned at the end of each working day. Scrap sediments which may have set
inside the soap hopper with a plastic spatula and flush them with warm water.
•
Clean the sediments from the door seal (mainly bottom part).
•
After cleaning the machine, at the end of a working day, open the door of the machine to enable airing the machine.
At the end of the day it is recommended to shut off all main water (steam) and electrical supply. However,
we don't mean the individual faucets of the machines that may not be touched once adjusted, but only
the main valves.
5.3. EVERY THREE MONTHS
•
Make sure that the machine is switched off by the main switch when maintenance work is being performed and
that the other workers are informed about it.
•
Dismantle the rear machine panel and check if the belt of wash motor is not damaged and if it has
the correct tension (see chapter 5.8.).
•
Check visually that all tubing, piping and connections inside machine are free from leaks.
•
Wipe and clean the inside of the machine, making sure that the control components are protected from moisture
and dust, during the cleaning operation.
•
Put on the cover panels and turn on the power supply.
5.4. EVERY SIX MONTHS
•
Regularly clean the filters of the water inlet.
•
Check the tightness of the bolts according to chapter 5.6.
•
For serious defects, the technical service of your dealer is always available.
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 TER AND -. THIS VOLTAGE

•
Clean and remove dirt and dust from:
– the cooling fin of the inverter
– the motor cooling fins
– the internal ventilator of the inverter (if present)
– the external ventilator (if present)
– the external air relieves of the machine
– check if ventilator in coolfins of inverter (if present) is functional
