0.2 IMPORTANT SAFETY INSTRUCTIONS
WARNING
To reduce the risk of re, electric shock, serious injury or death to
persons when using your washer, follow these basic precautions:
1. The actions described in these instructions are strictly reserved for personnel who have successfully completed training by
UNITY LAUNDRY SYSTEMS.
2. The company responsible for the Authorized Technical Service accepts full liability for the work done and any possible
consequences that may derive from it.
3. Any actions carried out by personnel who are not authorized by the manufacturer will be considered to be improper and will
result in the automatic voiding of the machine’s warranty.
4. The manufacturer will not accept responsibility for any physical and/or material damage caused by actions performed on the
machine undertaken by unauthorized personnel.
5. Do not store or install the machine in areas exposed to the ELEMENTS or where it may be splashed by water.
6. The room where the machine is located MUST comply with the environmental conditions (air venting, temperature, humidity,
etc.) specied in the technical specications table. NEVER INSTALL THE MACHINE IN ENVIRONMENTS where it will be
splashed with water or where there is a very high level of humidity in the atmosphere.
7. Install the washer according the INSTALLATION instructions. All connections for water, drain, electrical power and grounding
must comply with local codes and be made by licensed personnel when required. It is recommended that the machine be
installed by qualied technicians.
8. To prevent re and explosion, keep the area around machine free from ammable and combustible products. Do not add the
following substances or textiles containing traces of the following substances to the wash water: gasoline, kerosene, waxes,
cooking oils, vegetable oils, machine oils, dry-cleaning solvents, ammable chemicals, thinners, or other ammable or
explosive substances. These substances give off vapors that could ignite, explode or cause the fabric to catch re by itself.
9. Under certain conditions, hydrogen gas may be produced in a hot water system that has not been used for two weeks
or more. HYDROGEN GAS IS EXPLOSIVE. If the hot water system has not been used for such a period, before using a
washing machine turn on all hot water faucets and let the water ow from each for several minutes. This will release any
accumulated hydrogen gas. The gas is ammable, do not smoke or use an open ame during this time.
10. Never operate the washer with any guards, panels and/or parts removed or broken. DO NOT bypass any safety devices or
tamper with the controls.
11. Use washer only for its intended purpose, washing textiles. Never wash machine parts or automotive parts in the machine.
This could result in serious damage to the basket or tub.
12. Use only low-sudsing, no-foaming types of commercial detergent. Be aware that hazardous chemicals may be present.
Wear hand and eye protection when adding detergents and chemicals. Always read and follow manufacturer’s instructions
on packages of laundry and cleaning aids. Heed all warnings or precautions. To reduce the risk of poisoning or chemical
burns, keep them out of the reach of children at all times [preferably in a locked cabinet].
13. Always follow the fabric care instructions supplied by the textile manufacturer.
14. Loading door MUST BE CLOSED any time the washer is to ll, tumble or spin. DO NOT bypass the loading door switch by
permitting the washer to operate with the loading door open. Do not attempt to open the door until the washer has drained
and all moving parts have stopped.
15. Be aware that cold water is used to ush the soap dispenser. Avoid opening the dispenser lid while the machine is running.
16. Do not attach anything to the supply dispenser’s nozzles. The air gap must be maintained.
17. Do not operate the machine without the water reuse plug or water reuse system in place, if applicable.
18. Be sure water connections have a shut-off valve and that ll all hose connections are tight.
19. Keep washer in good condition. Bumping or dropping the washer can damage safety features. If this occurs, have washer
checked by a qualied service person.
20. Before servicing the machine, ensure that lockout and tag out procedures are in place for both electrical and water
connections.
21. Do not repair or replace any part of the washer, or attempt any servicing unless specically recommended in the user-
maintenance instructions or in published user-repair instructions.
22. To reduce the risk of an electric shock or re, DO NOT use an extension cord or an adapter to connect the washer to the
electrical power source.
23. Do not allow children to play on or in the washer. Close supervision of children is necessary when the washer is used near
children. This appliance is not intended for use by young children or inrm persons without supervision. Young children
should be supervised to ensure that they do not play with the appliance. This is a safety rule for all appliances.

24. DO NOT reach and/or climb into the tub or onto the washer, ESPECIALLY if the wash drum is moving. This is an imminently
hazardous situation that, if not avoided, will cause severe personal injury or death.
25. All installations required for the proper operation of the machine MUST be carried out by a duly accredited Registered
Installation Contractors, in compliance with the legal regulations applicable in the country of use.
26. Avoid carrying out any action on the machine without having rst read and understood the machine’s Installation and
Operating Manuals, paying special attention to the Safety Instructions.
27. Carrying out transport, installation, inspection routines, adjustments, maintenance, repairs, cleaning or any work on the
machines without applying safety measures or having the necessary technical know-how can lead to ELECTRICAL SHOCK
OR SERIOUS ACCIDENTS.
28. When tools designed for specic transport, installation, maintenance and repair routines are available, their use is
compulsory in order to avoid unnecessary risks.
29. Before carrying out any procedures on machines tted with pneumatic or hydraulic circuits:
• Make the machines COMPLETELY SAFE by following the instructions set out in the corresponding Manuals or by wedging
them with wooden blocks where necessary.
• Bear in mind that working on a component without having previously understood the role that it performs in the circuit as a

DISCONNECT IT FROM ALL THE ENERGY SOURCES.
• COMPLETELY disconnect the machine from the power supply and prevent the possibility of accidental reconnection by
mechanically locking the automatic external switch and/or the switch breaker. Stopping the machine with the NORMAL
STOP key or push-button is not enough.
• Disconnect the electrical connection of any circuit external to the machine; for example, external dosing equipment,
external vending units, folders or ironer feeders. These circuits are independent of the supply to the machine.
• Before beginning any procedure wait for at least ve minutes after the electrical disconnection, to eliminate risk of residual
voltage.
• Close and mechanically lock the manual supply valves.
• Check that the water bath has COMPLETELY drained, that no part of the machine is at an excessively high temperature
and that no parts are in movement through inertia.
31. DANGER! Some fault localization procedures require checking at different points of the electric circuit with the machine
connected to the power supply and other supply sources. When carrying out these procedures, respect the following
instructions:
• The appropriate checks must be carried out by ONLY ONE PERSON.
• During these procedures, ONLY remove the protective covers from the electric circuit and/or the inverter. Never remove the
covers protecting the moving parts of the machine.
35. Before the washer is removed from service or discarded, remove the door to the washing compartment.
36. Failure to install, maintain, and/or operate this washer according to the manufacturer’s instructions may result in conditions
which can produce bodily injury and/or property damage.
37. THE MANUFACTURER ACCEPTS NO RESPONSIBILITY IF THESE SAFETY INSTRUCTIONS AND ALL THE
INFORMATION IN THE CORRESPONDING MANUALS ARE NOT FOLLOWED. KEEP THESE INSTRUCTIONS IN A SAFE
PLACE.
NOTE: The WARNINGS and IMPORTANT SAFETY INSTRUCTIONS appearing in this manual are not meant to cover
all possible conditions and situations that may occur. Common sense, caution and care must be exercised when
