used above combustible flooring, such as carpet or wood. he washer
must be securely bolted nd grouted to a substantial concrete floor or
mounted nd grouted upon a suitable base that is securely bolted nd
grouted to a substantial concrete floor. See Machine Grouting section for
details.

EXCESSIVE VIBRA ION.
Allow a minimum 24 inches (610 mm) of clearance behind the rear of the
machine to provide access for motor service.
Installation on an isolated pad is NO recommended. Consult a structural
engineer for installations that will not be tied to a surrounding floor.

8514-302-001 REV B page 8
MOUN ING HEIGH
A concrete pedestal or steel-mounting base that elevates the machine
above the floor level is suggested to provide easy access to the loading
door.
Suggested Amount to Elevate Washer:
-300/350/350SWD: approximately 8 inches (203 mm)
Contact a Dexter laundry equipment distributor for recommended steel
mounting bases. Available steel mounting bases:
Washer Part Number Height
-300 9945-094-003 8” (203 mm) Single Base
-300 9945-094-004 8” (203 mm) Double Base
-350 9945-121-001 8” (203 mm) Single Base
-350 SWD 9945-151-001 6” (152 mm) Single Base
If an elevated concrete pedestal is desired, it should be embedded and
tied into the existing floor. DO NO install a pad on top of the existing
floor. Cut through existing floor as shown below. See Machine Mounting
Detail Figures for floor thickness and bolt sizes.

FOUNDA ION AND PAD OP IONS
All installations require reinforced concrete floors. Refer to appropriate
model Machine Mounting Detail Figures 1-1, 1-2 and 1-3 for minimum
floor thickness and minimum pad sizes. See mounting diagram for overall
washer dimensions.
Refer to appropriate model Figure 1-4 for side by side mounting
dimensions.

WASHER INS ALLA ION ON NEW FLOOR:
NEW PAD IED O EXIS ING FLOOR:
If the existing floor is not reinforced concrete that meets the minimum
thickness requirements, DO NO install a pad on top of the existing floor.
he existing floor and the machine pad must be tied together as one
piece as follows:
1) Cut an opening through the existing floor that is wider and deeper
than the washer as shown below. See Machine Mounting Details for
dimensions.
2) Excavate to a depth that allows for 6” [152] minimum of
compacted fill plus the minimum required concrete thickness. Also
excavate 2” [51] under the existing floor so that the new concrete is
poured under the floor as well.
3) Back fill with clean fill dirt and compact dirt, making sure to allow
for the minimum thickness concrete pad to be poured.
4) Drill holes around the perimeter of the existing floor to install
reinforcing bars to tie the new pad to the existing floor. Drill 2-1/2”
[64] deep into the existing floor on 12” [305] centers around the entire
perimeter.
5) Clean holes and fill half-way with acrylic adhesive rated for
commercial-grade machine installations.
6) Use #4 (60 ksi) reinforcing bar to tie the new pad to the existing
floor. ie the bars together at intersections and use supports to hold
bars in the proper depth in the pad.
7) After adhesive has cured, pour 4000 psi concrete up to level with
the existing floor plus any extra elevated pedestal desired 4-10” [102-
254].
Concrete must be done in one pour so that the entire pad cures as one
piece.

MACHINE ANCHORING
All installations require concrete floors and quality grade anchor bolts or
expansion anchors. Mounting hardware is not provided with the
machines. Refer to appropriate model Machine Mounting Detail Figures 1-
1, 1-2 and 1-3 for floor thickness and bolt sizes. See mounting diagram
for overall washer dimensions.
EXPANSION ANCHORS ARE NO RECOMMENDED FOR USE IN RAISED
CONCRE E PEDES ALS BECAUSE HE ANCHORS ARE OO CLOSE O AN

ANCHORING OP IONS:
1) Cast in place bolts headed by square fish plates. See Machine
Mounting Detail Figures 1-1 thru 1-3 for exact washer model.
Or after concrete has completely cured:
2) Use Hilti Adhesive System ‘HAS’ Rods and adhesive capsules. See
Machine Mounting Detail Figures 1-1 thru 1-3 for exact washer model.
3) Or use an equivalently rated epoxy or acrylic adhesive anchor.
As an installation aid, the anchor pattern can be found on the back panel
of the washers and can be used as a template. Compare panel to the
mounting dimension drawing to find the right holes. Example:

ANCHOR
PATTERN
MACHINE GROU ING
After concrete has cured completely and anchors have cured completely
into place:
1) Position washer over the mounting anchors.
2) Raise the washer 1/2” [12.7] off the mounting surface and place
spacers under the corners of the washer base.
3) Level the washer, leaving washer at least 1/2” [12.7] off the
mounting surface.
Do not permanently support the washer with spacers under the
corners. Machine must be grouted, and spacers must be removed.

8514-302-001 REV B page 13
4) Mix non-shrinking machinery grout according to the grout
instructions. he grout should not be too runny or too firm.
Completely fill the 1/2” [12.7] space between the washer base and the
mounting surface. Force grout under all base angles and plates until
completely filled. Fill around all anchor bolts.
5) Finger tighten all nuts to anchor bolts.
6) When the grout has started to stiffen (but before it is cured),
remove the spacers from the corners and allow the washer to settle
into the wet grout. Fill in any voids as necessary with additional grout.
7) Allow grout to completely cure, then tighten all nuts to securely
fasten the washer to the grouted mounting surface.
8) Retighten nuts after 5 days of operation and check quarterly.
If using a steel mounting base, first grout the steel mounting base to the
concrete floor using the above steps, then repeat the steps for mounting
and grouting the washer to the steel mounting base.
