BASIC SAFETY PRECAUTIONS
WARNING
To reduce the risk of fire, electric shock, or injury to persons when using this appliance, follow basic precautions, including the
following.
• Use this appliance only for its intended purpose as described
in this owner’s Manual.
•
Before use, the washer must be properly installed as
described in this manual.
•
Do not wash articles that have been previously cleaned in,
washed in, soaked in, or spotted with gasoline, dry cleaning
solvents, or other flammable or explosive substances,
as
they give off vapors that could ignite or explode.
•
Do not add gasoline, dry cleaning solvents, or other
flammable or explosive substances to the wash water.
These substances give off vapors that could ignite or
explode.
• Under certain conditions, hydrogen gas may be produced
in a hot water system that has not been used for 2 weeks
or more. HYDROGEN GAS IS EXPLOSIVE.
If the hot water
system has not been used for such a period, before using
the washer, turn on all hot water faucets and let the water
flow from each for several minutes.
This will release any
accumulated hydrogen gas. As the gas is flammable,
do not
smoke or use an open flame during this time.
•
Do not allow children to play on or in the washer. Close
supervision of children is necessary when the washer is
used near children.
•
Before the washer is removed from service or discarded,
remove the lid to prevent children from climbing inside.
•
Do not install or store the washer where it will be exposed
to the weather or freezing temperatures.
•
Do not tamper with controls.
•
Keep the area underneath and around your appliances free
of combustible materials (lint, paper, rags, etc.), gasoline,
chemicals and other flammable vapors and liquids.
•
Do not repair or replace any part of the washer or attempt
any servicing other than as described in this manual.
We
strongly recommend that any service be performed by a
qualified technician.
•
See Installation Instructions for grounding requirements.
•
ALWAYS follow the fabric care instructions supplied by the
garment manufacturer.
•
Do not place items exposed to cooking oil in your washer.
Items contaminated with cooking oils may contribute to a
chemical reaction that could cause a load to catch fire.
•
Use fabric softeners or products to eliminate static only as
recommended by the manufacturer.
• This washer is not designed for maritime use or for mobile
installations such as in RVs, aircraft, etc.
•
Turn off the water faucets and unplug the washer if the
machine is to be left for an extended period of time, such as
during vacations.
•
Do not use to dry articles containing foam rubber or
similarly textured rubber-like materials.
• Packaging material can be dangerous for children. There is a
risk of suffocation!
Keep all packaging from children.
•
Always check the inside of the washer for foreign objects
before loading laundry. Keep the lid closed when not in use.
•
Do not reach into the appliance if the tub or agitator is
moving.

following.
SAVE THESE INSTRUCTIONS
•
Unplug the washer before cleaning
to avoid the risk of
electric shock.
•
Never use harsh chemicals, abrasive cleaners, or solvents
to clean the washer.
They will damage the finish.
•
Do not put oily or greasy rags or clothing on top of the
washer.
These substances give off vapors that could ignite

Do not wash items that are soiled with vegetable or cooking
oil.
These items may contain some oil after laundering. Due
to the remaining oil, the fabric may smoke or catch fire by
itself.
•
Disconnect this appliance from the power supply before
attempting any user maintenance. Turning the controls to
the OFF position does not disconnect this appliance from
the power supply.
Failure to follow this warning can cause
serious injury, fire, electric shock, or death.
•
Do not combine laundry products for use in one load unless
specified on the label.
•
Do not mix chlorine bleach with ammonia or acids such
as vinegar. Follow package directions when using laundry
products.

with these warnings could result in serious injury to persons
or death.
•
Keep laundry products out of children’s reach. To prevent
injury to persons, observe all warnings on product labels.

INSTALLATION INSTRUCTIONS
Checking and choosing the proper
location
Install the washing machine on a solid floor that is strong and
rigid enough to support the weight of the washing machine,
even when fully loaded, without flexing or bouncing. If the
floor has too much flex, you may need to reinforce it to make
it more rigid. If the floor is not solid, it may cause severe
vibration and noise.
1
Clean the floor before installation.
- Make sure to select solid and smooth ground.
2
Two or more people are needed for moving and
unpacking the washing machine.
3
Allow for sufficient space between the walls and the
washing machine for installation.
Space requirements
You must allow sufficient space for water lines, the drain
line, and airflow.
NOTE
Be sure to allow for wall, door, or floor moldings that
y
may increase the required clearances.
