INSTALLATION OF THE RIGID WASHER-EXTRACTOR
WITHOUT PEDESTAL BASE
Using Expansion Bolts
Before anchoring the machine to the floor, 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 specified 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
floor. 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 floor
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 floor, 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 specified 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.
