Electrical shock prevention
DANGER
Electrical shock hazard will result in death or serious
injury. Before inspecting, maintenance or servicing
machines, power supply must be turned OFF. The
servicer needs to wait for at least ten (10) minutes af-
ter turning the power OFF. This machine must be
connected to a grounded metal, permanent wiring
system, and an equipment grounding conductor
must be run with the supply conductors and connec-
ted to the equipment grounding terminal on the ma-
chine. When the main switch is turned off, the inlet
terminals of the main switch are still under current.
The inverter remains charged with high voltage for
some time after powering OFF. Before starting in-
spection of the inverter, check for residual voltage
across main circuit terminals " + " and " - ". This
voltage must be below 30 VDC before the servicer
can access the inverter for inspection. Do NOT con-
nect manufacturer or other devices to the inverter to
manipulate the inverter behavior. No modification to
the settings are allowed. This is an imminently haz-
ardous situation that, if not avoided, will cause se-
vere personal injury or death.

system. Adequate ventilation must be provided to
avoid the back flow of gases into the room from ap-
pliances burning other fuels.
WARNING
ALWAYS disconnect the machine from Electrical
power, Water, Steam and all other connected sup-
plies during installation, before attempting any serv-
ice, replacing parts and maintenance.
electricity, steam, compressed air), than such means
must be part of the fixed installation external to the
machine. Such isolators shall be clearly identified.
They shall be capable of being locked if reconnec-
tion could endanger persons. After the energy
source is disconnected, follow the install procedure
to safely, dissipate any energy remaining or stored in
the circuits of the machine. Use machine only for its
intended purpose, laundry textiles. Never wash/dry/
iron something else than suitable linen, like poly-
mers, machine parts, automotive parts or other ferro
materials in the machine. This could result in serious

Electrical - Energy prevention
WARNING
Machine must be hard-wired.
Refer to the Earthing (grounding) instructions in the
INSTALLATION manual for the proper grounding of
the machine. In event of malfunction, breakdown or
leakage current, grounding will reduce the risk of
electrical shock and serve as a protecting device by
providing a path of least resistance of electrical cur-
rent. Therefore, it is very important, and the respon-
sibility of the qualified installer to assure the ma-
chine is adequately grounded at installation, follow-
ing all the national and local requirements. If there
are other washers or appliances with exposed con-
ductive parts, which can touch simultaneously, make
sure to make equipotential bonding between all
these appliances. The external protective terminal
for this purpose is located on the rear side of the ma-
chine frame. The minimum protection conductor's
cross section depends on the supply cable cross
section of the appliance of the highest current rating.
If the machine is not equipped with a supply mains
disconnecting device, means for disconnection must
by incorporated in fixed wiring in accordance with
overvoltage category Ill conditions and the relevant
local wiring rules. If disconnection is foreseen by
means of a plug, it must be placed and installed in
such a way that an operator can check from any of
the points to which he has access, that the plug re-
mains removed. If this is not possible, due to its in-
stallation, a disconnection with a locking system in
the isolated position shall be provided. Dangerous
voltages are present inside the machine. Disconnect
power from the machine before removing any cover
and guards, and before attempting any maintenance,
troubleshooting or service procedures or replacing
parts. To reduce the risk of an electric shock or fire,
DO NOT use an extension cord or an adapter to con-
nect the machine to the electrical power source. The
machine is not designed for use in IT networks. Ap-
plicable measures need to be provided.

Injury Prevention
WARNING
To reduce the risk of fire, electric shock, or in jury to
persons when using your machine, follow these pre-
cautions, including the following:
• Do not install or store the washer where it will be
exposed to water and/or weather conditions.
• To prevent fire and explosion, keep the area
around machine free from flammable and com-
bustible products. Do not add the following sub-
stances or textiles containing traces of the follow-
ing substances to the wash water: gasoline, kero-
sene, waxes, cooking oils, vegetable oils, ma-
chine oils, dry-cleaning solvents, flammable
chemicals, thinners, or other flammable or explo-
sive substances. These substances give off va-
pors that could ignite, explode or cause the fabric
to catch fire by itself.
• 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 or combination washer-dryer, turn on all
hot water faucets and let the water flow from each
for several minutes. This will release any accumu-
lated hydrogen gas. The gas is flammable, do not
smoke or use an open flame during this time.
• Use only low-sudsing, no-foaming types of com-
mercial deter gent. Be aware that hazardous
chemicals may be present. Wear hand and eye
protection when adding detergents and chemi-
cals. Always read and follow manufacturer's in-
structions on packages of laundry and cleaning
