WARNING
INSTALLATION AND SERVICING
INSTRUCTIONS ARE FOR USE BY
QUALIFIED PERSONNEL ONLY. TO
AVOID INJURY AND ELECTRICAL SHOCK
DO NOT PERFORM ANY SERVICING
OTHER THAN THAT CONTAINED IN THE
OPERATING INSTRUCTIONS, UNLESS
QUALIFIED.
WARNING
CARE MUST BE STRESSED WITH ALL
FOUNDATION WORK TO ENSURE A
STABLE UNIT INSTALLATION,
ELIMINATING POSSIBILITIES OF
EXCESSIVE VIBRATION.
WARNING
EXPANSION ANCHORS ARE NOT
RECOMMENDED FOR USE IN CONCRETE
PEDESTALS, BECAUSE THE ANCHORS
ARE TOO CLOSE TO AN EDGE, CAUSING
IT TO BREAK OUT.
WARNING
This machine is intended exclusively for
washing fabric articles in water. Do not
use outside of these guidelines.
WARNING
The laundry cleaning process utilizes
chemicals that could be potentially
harmful to persons or equipment. Contact
the chemical supplier for any risks with
their chemicals or combination of
chemicals and heed all warnings or
precautions specified. Under certain
conditions of use, hypochlorite (bleach)
generates chlorine gas. Chlorine is a
corrosive, oxidizing substance which, at
high concentrations and temperatures,
damages stainless steel and elastomers.
This same effect can also be caused by
other strongly oxidizing agents, including
ozone.
WARNING
Routine cleaning and maintenance
instructions are detailed in this manual.
They must be adhered to for best
performance and life. Never use
aggressive cleaning products to clean the
machine.
WARNING
Installation and service of the washing
machines must be performed by qualified
personnel.

5.2 Washer Characteriscs
Dexter Laundry industrial washing machines are designed to wash texle arcles in an indoor
environment by skilled or trained users. Cleaning is accomplished through the agitaon of the arcles in
water. Chemicals (if used) also help to separate soiled areas from the texles.
Dexter machines ulize high grade stainless-steel for the enclosure and drum. These surfaces limit the
growth of microbes and provide a durable and high-quality look. While properly anchored, standard
machines are capable of spinning the drum at speeds up to 100G. Similarly, the express machines are
capable of spinning the internal drum at speeds up to 200G. Drum rotaon is produced by an AC
(Alternang Current) motor controlled by a VFD (Variable Frequency Drive).

7.1.1 Foundaon Requirements
T-300 and 400:
This machine is designed for use on or over bare concrete floor - not to be used above
combustible flooring, such as carpet or wood. The washer must be securely bolted to a
substantial concrete floor or mounted upon a suitable base that is securely bolted to a
substantial concrete floor. Grouting is highly recommended, especially to the concrete surface.
See Machine Grouting section for details.
T-350, 450, 600, 650, 750, 900:
This machine is designed for use on or over bare concrete floor - not to be used above
combustible flooring, such as carpet or wood. The washer must be securely bolted and
grouted to a substantial concrete floor or mounted and grouted upon a suitable base that is
securely bolted and grouted to a substantial concrete floor. See Machine Grouting section for
details.
WARNING
CARE MUST BE STRESSED WITH ALL
FOUNDATION WORK TO ENSURE A
STABLE UNIT INSTALLATION,
ELIMINATING POSSIBILITIES OF
EXCESSIVE VIBRATION.
Allow a minimum 610 mm (24 inches) of clearance behind the rear of the machine to provide
access for motor service.
Installation on an isolated pad is NOT recommended. Consult a structural engineer for
installations that will not be tied to a surrounding floor.
WARNING
INSTALLATION AND SERVICING
INSTRUCTIONS ARE FOR USE BY
QUALIFIED PERSONNEL ONLY. TO
AVOID INJURY AND ELECTRICAL SHOCK
DO NOT PERFORM ANY SERVICING
OTHER THAN THAT CONTAINED IN THE
OPERATING INSTRUCTIONS, UNLESS
QUALIFIED.
INFORMATION
All washers must be installed in
accordance with all local, state and
national building, electrical, plumbing and
other codes in effect in the area.
Electrical safety of these washers has
been evaluated to the requirements of
European standard EN 60204-1.

7.1.2 Mounng Height
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:
T-300/350: approximately 203 mm (8 inches)
T-400/450/600: approximately 152 mm (6 inches)
T-650/750/900: approximately 102 mm (4 inches)
Contact a Dexter laundry equipment distributor for recommended steel mounting bases.
Available steel mounting bases:

If an elevated concrete pedestal is desired, it should be embedded and tied into the existing
floor. DO NOT 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.
WARNING
EXPANSION ANCHORS ARE NOT
RECOMMENDED FOR USE IN CONCRETE
PEDESTALS, BECAUSE THE ANCHORS
ARE TOO CLOSE TO AN EDGE, CAUSING
IT TO BREAK OUT.

7.1.3 Foundaon and Pad Opons
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 in Machine
Mounting Details.
Figure 7-1 Washer Installaon on Exisng Floor
Figure 7-2 Washer Installaon on New Floor
7.1.3.1 New Pad to Exisng Floor
If the existing floor is not reinforced concrete that meets the minimum thickness requirements,
DO NOT install a pad on top of the existing floor. The 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 152mm (6inches) minimum of compacted fill plus
the minimum required concrete thickness. Also excavate 51mm (2inches) 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.
