■
The Circuit must be a dedicated circuit and may not be
combined with any lighting circuit.
■
Adequate grounding is essential to washer operation.
■
Do not fuse the neutral or grounding circuit.
■
Certain internal parts are intentionally not grounded and may
present a risk of electrical shock only during service. Do
not contact the inlet valve coil straps while the appliance is
energized.
■
This appliance must be connected to a grounded metal,
permanent wiring system, or an equipment-grounding
conductor must be run with the circuit conductors and
connected to the equipment-grounding terminal or lead on
the appliance.
■
Read all instructions before using the washer.
■
Do not wash articles that have been previously cleaned
in, washed in, soaked in, or spotted with gasoline,
dry-cleaning solvents, or other ammable or explosive

explode.
■
Do not add gasoline, dry cleaning solvents, or other
ammable 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
ow from each for several minutes. This will release any
accumulated hydrogen gas. As the gas is ammable, do
not smoke or use an open ame during this time.

INSTALLATION OF THE WASHER-EXTRACTOR WITHOUT
PEDESTAL BASE
Anchoring MYR models (Rigid Machines)
A static engineer must be consulted to evaluate the static
requirements with respect to permissible loads, vibrations, and
noise level in the building where the washer is installed.
The manufacturer does not recommend installing the washer
in a room with a cellar underneath or on a oor with rooms
underneath. The washer must be leveled from side to side, as
well as from front to rear. If the washer is not properly leveled,
it may become out of balance even though the drum remains
balanced.
Rigid washers must be anchored to the oor. Correct
construction of the anchorage to the oor is essential to ensure
correct operation of the appliance and to prevent serious
damage to its structure.
Rigid washers must not be installed on non-foundation oors
without authorization from a technician familiar with the structure
and weight-bearing capacity of the building.
Check the weight of the washer and its contents, plus the
dynamic forces generated during spinning. The manufacturer
does not accept responsibility for any damage due to vibration in
this type of installation.
Anchoring MYS models (Soft Machines)
Shipping brackets need to be uninstalled from the soft washers
prior to operation. Remove the toe panel, front panel, and rear
cover to access the shipping bracket. The shipping brackets are
painted white for ease of identication.
Leveling feet are provided with soft machines. Use the feet to
level the machine in it's nal operating location. Use the level to
level the top of the washer. Turn the leveling legs to adjust the
setting. Check that the washer does not move front-to-back,
side-to-side, or diagonally when pushed on its top edges. Keep
the legs as short as possible for best performance.
Once the washer is leveled the lock nuts must be tightened up
against the top of the foot bushing with the 17 mm (11/16") open
end wrench. This will keep the setting from changing.
Anchoring is not required but four 12 mm holes are provided if
anchoring is desired.
There is a whisker switch behind the toe panel, located below
the tub and to the left of the drain. This switch is set at the
factory, but in the event that it falls out of adjustment, with the
shipping brackets installed, this switch should be set so the
whisker is centered in the opening.
WARNING
Crush Hazard
Washer can tip over if not properly installed on
platform or pedestal.
Shipping brackets must be removed per installation
instructions before operating.
Failure to follow these instructions can result in death
or serious injury.
WARNING
Crush Hazard
Washer can tip over if not properly installed on
platform or pedestal.
Washer must be bolted to the floor per installation
instructions.
Failure to follow these instructions can result in death
or serious injury.
12
INSTALLATION OF THE RIGID WASHER-EXTRACTOR
WITHOUT PEDESTAL BASE
Using Expansion Bolts
Before anchoring the machine to the oor, make sure that its
minimum resistance is equal or higher than 3,500 psi (25 N/mm
2
).
First mark the locations of the mounting holes using the
dimensions specied in the “Rigid Washing Machines” chart.
Next drill the mounting holes. Follow the manufacturing
installation instructions, but the holes must be at least 4"
(100 mm) deep. The holes must not go all the way through the
oor. Clean the holes with compressed air.
For the smoothest operation Whirlpool recommends that the
washer be set with a precision, high strength, non-metallic,
non-shrink grout designed for precision grouting. Grout should
have a minimum compressive strength of 10,000 psi (69 MPa),
when mixed to a plastic consistency and fully cured.
a. If the washer is to be grouted in, it should be level and
spaced between 3/8" (9 mm) and 1/2" (13 mm) off the oor
to make room for the grout.
b. Remove the washer leaving the spacers behind.
c. Mix the grout to a plastic consistency per the manufacturer's
instructions.
d. Trowel the grout in to a depth slightly greater than the height
of the spacers.
e. Reinstall the washer over the mounting fasteners. Use the
fasteners to pull the washer down securely on the spacers.
Do not fully torque the fasteners.
f. Clean away any excess grout outside the washer as per the
manufacturer's instructions.
g. Allow the grout to set for the minimum time recommended
by the grout manufacturer for light use.
h. Tighten the bolts until the machine is securely fastened.
If not using grout, place the washer-extractor in position over the
holes, then insert the expansion bolts in the holes. Be sure to
use 5/8-11 (M16) expansion bolts, and that they protrude above
the surface by 2" (50 mm). Once in place, tighten the bolts. Place
the washer-extractor in position above the bolts, and gradually
tighten the nuts one after another to 195 Nm (144 ft lb).
Using J-bolts
Before anchoring the machine to the oor, make sure that its
minimum resistance is equal or higher than 3,500 psi (25 N/mm
2
).
First mark the locations of the mounting holes using the
dimensions specied in the “Rigid Washing Machines” chart.
Next make holes to a depth, at minimum, equal to 4" (100 mm).
Make the holes big enough to insert the J-bolt and clean using
compressed air. Insert the J-bolts in the holes and secure using
a suitable anchoring compound, ensuring that the bolt protrudes
above the surface by 2" (50 mm). Be sure to use 5/8-11 (M16)
J-bolts.
Place the washer-extractor in position above the bolts, and
gradually tighten the nuts one after another 195 Nm (144 ft lb).
Check the condition of the J-bolts one week after installation.

INSTALLATION INSTRUCTION
Connect the Drain Hose
1. The drain hose can be found shipped inside the drum
with the installation kit. The clamp for this hose is in the
installation kit. Attach the drain to the drain connection
located near the bottom of the rear of the washer. This is a
gravity-fed system, so you must install the drain hose with
the outlet lower than the drain connection to ensure proper
drainage. Do not kink the hose.
Drain Hose
2. The drain hose should end over, or in a floor drain or
drainage canal.
3. The drainage canal or drain pipe must be sized properly
to handle the total output of all washers connected to the
system. Each time a washer is added to the drain pipe,
the size of the pipe must increase to accommodate the
additional volume. The drain pipe at the first washer must
be 3" (76 mm) diameter. The pipe must increase to
4" (100 mm) diameter before the second washer and
5" (127 mm) diameter before the third washer.
Drain Connections
Use the provided drain hose to connect the washer’s drain pipe
to the facility drain or drain channel. Secure with the provided
clamp. The capacity of discharged water for each washer model
is 55.5 gallon/min (210 L/min).
Water Hardness
Determine the water hardness level in water supply. Good wash
results are dependent on water hardness. In areas that have
medium and very hard water levels, a water softener may be
required.
Contact your water or soap distributor for determining the proper
soap and detergents to be used with your hardness levels for the
best wash results.
Water Supply Connections
Washers have 2 water inlets. For connection dimensions, see
“Dimensions and Technical Specications”.
1. Always use the exible hoses delivered with the washer. Do
not use a xed connection to the water supply.
2. Keep proper water pressure within range. See “Dimensions
and Technical Specifications”.
3. The water connection to the washer requires a 3/4" British
Standard Pipe Thread fitting. The British Standard Pipe
Thread end is identified with a label. Threading an GHT fitting
or the GHT end of the adapter hose will damage the threads
of the washer.
4. Flush water lines to remove debris. For countries with metric
water supply connection, see “NOTE” below. Install the GHT
(the end with no label) side of the inlet hoses to the hot and
cold supply lines. Tighten fittings.
NOTE: Metric thread adapters are provided in countries
that require them. These brass adapters have internal BSPP
threads and external NPT threads. One adapter should be
attached (with sealing washer) to the GHT end of each water
inlet hose. With this assembly, metric threads are now on
both ends of the water inlet hose.
5. Attach the BSPP (the end with the label) end of adapter
hoses to the washer. (On 55R, 55S, 65R, and 65S models,
there is a hose screen included in the installation kit that
needs to be placed here). Tighten fittings.
6. Turn on water and check for leaks in the system.
External Supply Connections
All external liquid soap hose connections must be tight. Double
check that the clamps are tight after connections are made.
Make sure any unused open connections are sealed with an
appropriate cover.
The connections for the liquid soap are on the rear of the
washer and must be drilled open in order to use them. Only drill
out the connections that will be used. There are 8
3/8" (9 mm) diameter connections; use a 5/16" (8 mm) diameter
drill bit to drill out these holes. There can only be 8 pumps in the
system. Be sure to clean out all the drill shavings completely so
they do not clog the inlets and hoses. Connect to liquid soap
pumps to the left openings rst. Set the ow rate of the pumps
between 16 and 26 gallon/hr (60 and 100 L/hr).
IMPORTANT: The incoming water dilutes the liquid soap and
brings it into the tub assembly.
Check with your liquid soap provider to ensure that your soap
is inert to Polypropylene (PP) and Polyvinyl Chloride (PVC)
materials.
Make sure the hoses and wiring for the liquid soap pumps are
not damaged, pinched, rubbed or damage to the machine could
occur.
The liquid soap pumps used must be capable of providing the
requested quantity in less than 30 seconds.

ELECTRICAL CONNECTION
Connection to Washer:
The washer must be electrically grounded in accordance with all
local codes or, in the absence of local codes, with the National
Electrical Code, ANSI/NFPA 70, latest edition, or Canadian
Electrical Code, CSA C22.1
Direct Wire Installation:
Power supply cable must match power supply (3-wire) and be:
■
To access the disconnect, lift the top cover and support it
with the prop rod.
■
Copper wire of appropriate gauge for amperage requirement
(see “Manufacturer’s Recommended Minimal Conductor
section”). Solid wire is recommended. Do not use aluminum
wire.
■
Flexible armored cable or exible conduit must be used
for the supply connections. Use the hole in the rear of the
washer for routing. Connection is made directly to the
disconnect switch inside the back top panel of the washer.
The Aluminum Lug for Ground is next to that disconnect
body. A Flat-head screwdriver can be used for the power
wires to the disconnect as well as the ground to the
lug. Incoming service wires are applied to the top of the
disconnect body. If the washer is single phase, (only
2 power wires) the outside positions of the disconnect should
be used (leaving the center pole empty). Tighten down all
connections including the unused position in the single-
phase service case. Leaving a small radius of slack for the
wires inside the washer, check that the cable is well held in
place.
■
Check the rating plate on the washer. Make sure that the
supply phase and voltage match the rating of the washer.
Some locations require an autonomous power switch (I) at
the current input, with a minimum of 0.12" (3 mm) between
contacts. Fit a 300 mA, type A, immediate response
differential protection. Check your local regulations. Insert the
exible armored cable or exible conduit through the hole in
the rear panel. Secure the armored cable or conduit to the
rear panel. Connect the wiring per the correct illustration.
