WARNING - THIS WASHER IS EQUIPPED WITH DEVICES AND FEATURES RELATING TO ITS SAFE
OPERATION TO AVOID INJURY OR ELECTRICAL SHOCK, DO NOT PERFORM ANY SERVICING UNLESS
QUALIFIED TO DO SO
IT IS THE RESPONSIBILITY OF THE OWNER TO CHECK THIS EQUIPMENT ON A FREQUENT
BASIS TO ASSURE ITS SAFE OPERATION
A machine should NOT be allowed to operate if any of the following occur:
- Excessively high water level
- If machine is not connected to a properly grounded circuit
- If the door does not remain securely locked during the entire cycle
- Vibration or shaking from an inadequate mounting or foundation
WARNING - SAFETY PRECAUTIONS
- Always shut off power and water supply before servicing
- Do not overload the washer
- Do not open door when cylinder is in motion or it contains water
- Do not bypass any safety devices of this washer
- Do not use volatile or flammable substances in or near this washer
- Keep all panels in place They protect against shock and injury and add rigidity to the washer
PREVENTIVE MAINTENANCE REQUIREMENTS
DAILY
- Check that the loading door remains securely locked and cannot be opened during an entire
cycle
- Clean the top, front, and sides of the cabinet to remove residue
- Clean the soap dispenser and lid and check that all dispenser mounting screws are in-place and
tight
- Check the loading door for leaks Clean the door seal of all foreign matter
- Leave the loading door open to aerate the washer when not in use
QUARTERLY
- Make sure the washer is inoperative by switching off the main power supply
- Check the V-belts for wear and proper tension
- Clean lint and other foreign matter from around motor
- Check all water connections for leaks
- Check the drain valve for leaking and that it opens properly
- Wipe and clean the inside of the washer and check that all electrical components are free of
moisture and dust
- Remove and clean water inlet hose filters Replace if necessary
- Check anchor bolts Retighten if necessary
IMPORTANT: Replace any and all panels that were removed to perform daily and/or quarterly
maintenance

2 INSTALLATION INSTRUCTIONS
All washers must be installed in accordance with all local, state and national
building, electrical, plumbing and other codes in effect in the area
WARNING:
THESE 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.
2 1 FOUNDATION 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, 950, 1200, 1450:
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
CARE MUST BE TAKEN WITH ALL FOUNDATION WORK TO ENSURE A
STABLE UNIT INSTALLATION, ELIMINATING POSSIBILITIES OF
EXCESSIVE VIBRATION
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 NOT recommended Consult a structural
engineer for installations that will not be tied to a surrounding floor
2 2 MOUNTING 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 8 inches (203 mm)
T-400/450/600: approximately 6 inches (152 mm)
T-650/750/900/950/1200/1450: approximately 4 inches (102 mm)

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
EXPANSION ANCHORS ARE NOT RECOMMENDED FOR USE IN CONCRETE
PEDESTALS BECAUSE THE ANCHORS ARE TOO CLOSE TO AN EDGE,
CAUSING IT TO BREAK OUT
2 3 FOUNDATION AND PAD OPTIONS
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
2 3 1 WASHER INSTALLATION ON EXISTING FLOOR:

8514-297-001 REV F page 8
2 3 2 WASHER INSTALLATION ON NEW FLOOR:
2 3 3 NEW PAD TIED TO EXISTING 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 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 Tie 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

2 4 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 NOT RECOMMENDED FOR USE IN RAISED
CONCRETE PEDESTALS BECAUSE THE ANCHORS ARE TOO CLOSE TO AN
EDGE, CAUSING IT TO BREAK OUT
ANCHORING OPTIONS:
2 4 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 4 2
Use Hilti Adhesive System ‘HAS’ Rods and adhesive capsules See
Machine Mounting Detail Figures 1-1 thru 1-3 for exact washer model
2 4 3
