HANDBOOK 1. General
This washer extractor is controlled by a microprocessor-based program control unit placed on
the loading side. There are many advantages to this equipment, including :
• Timing, levels and temperatures are controlled with great precision and flexibility.
• The large display screen means that detailed information on wash programs, machine status
and operations, wash times and temperatures can be accessed in plain language
• It is possible for the user to create new wash programs, and to adapt programs with great
precision, on the basis of experience and to suit various types of textile, degrees of soiling
etc.
• a very high level of machine safety through continuous monitoring and built-in safety inter-
locks.
• The program control unit has a reader for "smart cards". These are cards the size of a credit
card which contain a memory chip. Smart cards allow the user to :
- transfer wash programs between a PC and the washer extractor, or from one washer
extractor to another
- run programs straight from a card
• Great flexibility during program operation :
- rapid advance both forwards and backwards in the program
- the user can change temperatures, program module lengths and extraction speeds direct-
ly, during program operation
- change to running a different wash program, at any time during program operation of the
washer extractor.
During a wash : "Pause" key.
Before and after a wash, and during programming : "Move back key".
By pressing this key repeatedly you can move backwards through the menus you have navigated through. This will

1. General
A very high working safety level of the machine is achieved thanks to a continuous monitoring
and built-in safety devices.
Even the compound textile fabrics can be washed at a high temperature with no crumpling risk
thanks to a special cooling process before the rinsing cycle.
In order to avoid an excessive mechanical fatigue during the hydro-extraction process, the
machine is equipped with an unbalance detector. If the latter detects the least unbalance of the
load, the hydro-extraction cycle is interrupted and the machine fills with water to make a new
distribution of the linen possible.
The machine then resumes the distribution speed and another hydro-extraction cycle begins.
The machine can also be controlled sequence by sequence and is equipped with a keyboard
for the manual control of certain functions.
Note about the A.C. power

instructions
Preliminary instructions
Before any use, it is compulsory to read the instruction handbook.
Users must have learnt how the machine operates.
The identification plate is placed on the left hand side of the machine.
In order to prevent any risk of fire or explosion, flammable products should never be used to
clean the machine.
Any repair or maintenance intervention should be carried out by qualified personnel only.
Detergents used in laundry are particularly agressive. No stainless steel is able to resist their
corrosive actions. Detergent dispenser must consequently be considered as wearing parts
likely to be replaced.

4. Preliminary
instructions
Ensure that the machine is not loaded beyond its nominal capacity
(see "Specific load" in the instruction booklet’s technical charac-
teristics).
An excessive load has consequences for the lifetime of the ma-
chine’s organs, as follows:
· Rapid destruction of the suspension elements (springs, shock
absorbers);
· Excessive fatigue of motorisation elements (engine, belt);
· Rapid reduction of lifetime of drum bearings (rolling bearings);
· Opening and destruction of drum doors and tank doors during
oil dehydration.
This is particularly important for your safety and that of others.
The consequence is an immediate cancellation of the warranty.
The use and handling of chemical products such as detergent, chlo-
rine, acids, antiliming agents etc... may create hazards for health and
environment ; the following precautions should be taken.
- Do not breathe the dusts or steam.
- Avoid contact with skin or eyes (may cause burns).
- In case of important spillage, wear a protecting mask, gloves, and
eye protectors.
- Handle with care.
- Consult the use and first aid advice on the packings.
- Do not dispose pure products in the environment.
The machine can work without the protective casing when the electric
supply is not cut off.
Interlock the main isolating switch with a padlock.
Close the steam or gas inlet valves.

Distributor Letter
Chemical System Responsibility
Disclaimer
The following policy should be considered and understood as a warranty/disclaimer to customers
operating textile care installations where liquid supply (chemical) systems use or may use peristaltic
pumps to inject supplies into equipment.
To Whom it May Concern :
We, the undersigned, accept no responsibility for loss or damage when, during periods of non-use,
concentrated chemicals leak, spray or "dribble" onto any part of our machines or their contents.
It is well known that many pumped liquid chemical systems tend to permit concentrated chemicals
to dribble out of the injection tubes when the system has not been used for relatively long periods
of time – as after working hours and during weekends. This puts highly concentrated corrosive
chemicals in direct contact with dry stainless steel surfaces and often directly on any textiles left in
the machine. Chemical deterioration (rusting) of the stainless steel and damage to the textiles is the
inevitable result.
It is absolutely useless to flush the affected sites after each injection because the harmful dribble
always occurs later – after the machine is no longer in use. One seemingly foolproof solution for
"dribbling chemicals" (which we highly recommend but obviously cannot guarantee) is to locate the
chemical tanks and pumps well below the injection point on the machine (so the contents of the injec-
tion tube(s) cannot siphon into the machine) and to completely purge the just-used chemical injec-
tion tube(s), or manifold, with fresh water after every injection so that only fresh water (which cannot
cause a problem) can dribble out. Naturally, this – or any other solution – is the sole responsibility of
the pump and/or chemical supplier (not the machine manufacturer).
Additionally, external chemical leakage is dangerous to personal health and safety, and will also
cause severe damage to machines and/or their surroundings. The installer and/or user of the chemi-
cal injection system must make sure there are no external chemical leaks and that excessive pres-
sure can never build up in any chemical delivery tube, because excessive pressure can burst the
tube, or disconnect it from the machine, and spray dangerous concentrated chemicals about the
premises.
The machinery manufacturer is not, and cannot be, responsible for compliance with the above.
