will have the same published manual number, but the latest available ECN. This provides the user
with the latest information applicable to his machine. Similarly all documents comprising the
manual will be the latest available as of the date the manual was printed, even though older ECN
dates for those documents may be listed in the table of contents.
When communicating with the Milnor factory regarding this manual, please also provide the
other identifying information shown on the cover, including the publishing system, access date,
and whether the document ECN’s are the latest available or exact.
Best Available Information—This manual contains the most accurate and complete
information available when Milnor shipped your machine/software. Products are occasionally
released with the best available documentation, even though the device identification (model
numbers, etc.) on the documentation does not explicitly include the delivered model. In such
cases, use the documentation provided.
Although unlikely, incorrect manuals may have been shipped with your machine. If you believe
you received the wrong manuals, or if you need specific information about any aspect of your
machine not addressed in the provided documentation, contact the Milnor Customer Service
group.
References to Yellow Troubleshooting Pages—This manual may contain references
to “yellow pages.” Although the pages containing trouble-shooting procedures are no longer
printed on yellow paper, troubleshooting instructions, if any, will be contained in the easily

About the Forces Transmitted by Milnor® Washer-extractors
During washing and extracting, all washer-extractors transmit both static and dynamic (cyclic)
forces to the floor, foundation, or any other supporting structure. During washing, the impact of
the goods as they drop imparts forces which are quite difficult to quantify. Size for size, both
rigid and flexibly-mounted machines transmit approximately the same forces during washing.
During extracting, rigid machines transmit forces up to 30 times greater than equivalent flexiblymounted models. The actual magnitude of these forces vary according to several factors:
• machine size,
• final extraction speed,
• amount, condition, and type of goods being processed,
• the liquor level and chemical conditions in the bath preceding extraction, and
• other miscellaneous factors.
Estimates of the maximum force normally encountered are available for each Milnor® model and
size upon request. Floor or foundation sizes shown on any Milnor® document are only for ongrade situations based only on previous experience without implying any warranty, obligation, or
responsibility on our part.
1.
Rigid Machines
Size for size, rigid washer-extractors naturally require a stronger, more rigid floor, foundation, or
other supporting structure than flexibly-mounted models. If the supporting soil under the slab is
itself strong and rigid enough and has not subsided to leave the floor slab suspended without
support, on grade installations can often be made directly to an existing floor slab if it has enough
strength and rigidity to safely withstand our published forces without transmitting undue
vibration. If the subsoil has subsided, or if the floor slab itself has insufficient strength and
rigidity, a deeper foundation, poured as to become monolithic with the floor slab, may be
required. Support pilings may even be required if the subsoil itself is “springy” (i.e., if its
resonant frequency is near the operating speed of the machine). Above-grade installations of rigid
machines also require a sufficiently strong and rigid floor or other supporting structure as
described below.
2.
Flexibly-mounted Machines
Size for size, flexibly-mounted machines generally do not require as strong a floor, foundation, or
other supporting structure as do rigid machines. However, a floor or other supporting structure
having sufficient strength and rigidity, as described in Section 3, is nonetheless vitally important
for these models as well.
3.
How Strong and Rigid?
Many building codes in the U.S.A. specify that laundry floors must have a minimum live load
capacity of 150 pounds per square foot (732 kilograms per square meter). However, even
compliance with this or any other standard does not necessarily guarantee sufficient rigidity. In
any event, it is the sole responsibility of the owner/user to assure that the floor and/or any other
supporting structure exceeds not only all applicable building codes, but also that the floor and/or
any other supporting structure for each washer-extractor or group of washer-extractors actually
has sufficient strength and rigidity, plus a reasonable factor of safety for both, to support the
weight of all the fully loaded machine(s) including the weight of the water and goods, and
including the published 360º rotating sinusoidal RMS forces that are transmitted by the
machine(s). Moreover, the floor, foundation, or other supporting structure must have sufficient
PELLERIN MILNOR CORPORATION
About the Forces Transmitted by Milnor® Washer-extractors
8
rigidity (i.e., a natural or resonant frequency many times greater than the machine speed with a
reasonable factor of safety); otherwise, the mentioned 360º rotating sinusoidal RMS forces can be
multiplied and magnified many times. It is especially important to consider all potential vibration
problems that might occur due to all possible combinations of forcing frequencies (rotating
speeds) of the machine(s) compared to the natural frequencies of the floor and/or any other
supporting structure(s). A qualified soil and/or structural engineer must be engaged for this
purpose.

Figure 1 above is intended to depict both on-grade and above-grade installations and is equally
applicable to flexibly-mounted washer-extractors, as well as to rigid models installed either
directly on a floor slab or on a foundation poured integrally with the slab. Current machine data is
available from Milnor® upon request. All data is subject to change without notice and may have
changed since last printed. It is the sole responsibility of every potential owner to obtain written
confirmation that any data furnished by Milnor® applies for the model(s) and serial number(s) of

Avoiding Damage From Allied Remote Chemical Delivery Systems
Milnor® does not manufacture or supply remote chemical delivery systems and this document is
meant only to illustrate some of the possible problems that can be minimized during installation
of such systems by the chemical supply company. Milnor washer-extractors and CBW
washers (tunnels) are available with convenient inlets for such systems (see Figure 1). Most
common of the types of systems currently used in commercial laundering operations are pumped
chemical systems. Other types, such as constant pressure, re-circulating ring main systems have
also been, and may continue to be used with Milnor equipment.
This document warns about some of the possible hazards posed by chemical systems and lists
certain requirements needed to minimize those hazards. The procedures for interfacing with allied
chemical systems and information pertinent to chemical use in general are provided elsewhere in
the product manuals (see Note 1).

Milnor has manufactured washer-extractors and tunnel washers with the same stainless steel
specification since its founding. Every batch of steel used is certified and documented by the steel
mill. Testing of samples damaged by corrosion have, in every case, proven the steel to be well
within the AISI 304 specification.
PELLERIN MILNOR CORPORATION
Avoiding Damage From Allied Remote Chemical Delivery Systems
13
Chemical products commonly found in the laundry industry, when used in established dosages
and proper operating parameters, under the auspices of an experienced chemical specialist, should
produce satisfactory results, with no consequential detrimental effects. The industry has published
standards in Riggs and Sherrill, “Textile Laundering Technology”. However, the stainless steel
can be damaged and even destroyed by abnormal contact with chlorine bleach, hydrofluosilicic
acid and other commonly used chemicals, as will occur if chemicals are unintentionally leaked
into the machine, particularly when it is no longer in use and especially when machine surfaces
are dry.
Some chemical systems have been found to permit chemicals to dribble from the supply lines, or
worse, to siphon from the supply tank into the machine, during operation and long after the
system is shut down—as after working hours and during weekends. If this occurs, deterioration
(rusting) of the stainless steel and damage to any textiles therein will inevitably result. If this
condition goes undetected, machine damage is likely to be catastrophic. No machine is
immune to such damage.
CAUTION 1 : Equipment and Textile Damage Hazards
—Chemicals leaked into the
machine, particularly when it is idle can destroy machine components and textiles left in the
machine. Pellerin Milnor Corporation accepts absolutely no responsibility for damage to its
equipment or to textiles therein from abnormal contact with chemicals.
• Ensure that the chemical system prevents unintenti ona l rele ase of chemicals.
• Inspect regularly for proper operation and evidence of damage.
2.
Requirements for Chemical Systems Used With Milnor Machines
It is the responsibility of the chemical system manufacturer and supplier to ensure that their
system is safe for personnel and equipment. Some important points are described below.
2.1.
Ensure the System Cannot Siphon.
—The supply system must be designed to
counteract any siphoning that could occur as a result of having a sealed supply line between the
bottom of the chemical tank and the internal machine connection at the drain trough. As shown in
the Figure 2 examples, if the pump (P) and/or the valving does not provide positive closure and
there is no vacuum breaker protection, siphoning is likely to occur. In each of the Figure 2
illustrations, the volume of chem ical in the tank above th e siphon level (S), and indi ca ted by
shading, will flow into the machine.

2.2.
Ensure the Chemical Lines Cannot Dribble
—The pumped chemical system may
provide a means of positively closing the chemical line at the pump location, but not at the
injection site. Hence, any concentrated chemical that remains in the injection line between the
pump and the machine is free to flow into the machine. Some examples of this are shown in
Figure 3.

Design and Installation Recommendations
It is the responsibility of the chemical system manufacturer and supplier to use whatever
measures are necessary to ensure that their system is safe for personnel and equipment. The
following are some of the possible methods the manufacturer or supplier may wish to use, as
appropriate.
3.1.
Siphoning: Positively close the line.
—If the pump does not provide positive closure
when the system is off, employ a shutoff valve in the line to serve this purpose.
3.2.
Siphoning: Break the siphon.
—Provide an air gap or vacuum breaker in the chemical
delivery line. This must be located above the “full” line of the tank.
3.3.
Dribbling: Flush the entire chemical delivery line.
—If any concentrated chemical
that remains in the injection line between the pump and the machine is free to flow into the
machine, employ a system that flushes the entire line between the pump and the injection point
with fresh water after each injection.
PELLERIN MILNOR CORPORATION
3.4.
16
Dribbling: Locate the entire chemical line below the machine inlet.
—
Assuming the chemical system does not retain any line pressure and that the pump provides
positive closure when the system is off, locate the entire chemical delivery line below the level of
the chemical inlet. An example of this is shown in Figure 4.

All personnel who may work with the chemical system (e.g., chemical system manufacturer,
chemical system supplier, chemical supplier, operator, maintenance personnel) should be vigilant
in observing for leaks in the system. When connecting, or reconnecting chemical lines, whether at
installation, after taking samples, or when replacing components, at a minimum ensure that:
1. the proper components are used,
2. all connections are the proper fit, and
3. all components are securely connected.
CAUTION 2 : Injury and Damage Hazards
—Chemicals leaking from a chemical system
may be corrosive or toxic. Such chemicals can injure personnel and damage equipment.
• Use care when connecting chemical lines.
• Inspect regularly for leaks.

Handling and Setting Procedures for Rigid Mount WasherExtractors
1. Handling Precautions
1. Remove the protective coverings (leaving the machine on shipping skids) and carefully
examine for possible shipping damage. If the machine is damaged, notify the
transportation company immediately.
Note 1: Once the machine is given to the carrier for delivery, it is the sole responsibility of the carrier
to ensure that no damage occurs during transit. In addition to readily apparent damage, carriers are
liable for concealed damage. Do not hesitate to file a claim with the carrier if the machine is
damaged in any way during shipment. Milnor® will be glad to assist you in filing your claim, but is
not responsible for any shipping damage to the machine once it has been delivered to the carrier in
good condition.
2. Consult Milnor® for instructions if crane lifting is required.
3. Use skids with the forklift. If possible, leave the machine on the shipping skids until it is
about to be placed in its final position. Once the skids are removed, take care in placing forks
under the machine. Do not allow the forks to come in contact with valves, piping, motors,
etc., located under the machine.
4. Never push, pull, or exert pressure on any components that protrude from the machine frame
(shell front, door, supply injector, electric boxes, controls, belt guard, conduits, inlet piping,
etc.).
5. Ensure that the shell door is closed and secured.
2. Site Requirements
2.1. Space Requirements
1. All openings and corridors through which equipment must pass during installation must be
large enough to accommodate the width and the height of the machine (as shown on the
dimensional drawings). It is occasionally possible to reduce the overall dimensions by
removing piping or other special modifications. Consult Milnor® for additional information.
2. Sufficient clearance must be provided for normal operation and maintenance procedures.
2.2. Operational Requirements
1. Allow sufficient ventilation for heat and vapors of normal operation to dissipate.
2. Provide easy access to controls. Operators must be able to reach and view all status lights,
machine controls, and any additional controls associated with the machine (e.g., electrical
power connections, water and steam shut-offs, etc.).
2.3. Foundation Requirements—The machine must be anchored in accordance with the
installation instructions. The floor and/or all other support components must have sufficient
strength (and rigidity with due consideration for the natural or resonant frequency thereof) to
withstand the fully loaded weight of the machine, including the wet goods and any repeated
sinusoidal (rotating) forces generated during its operation. Determining the suitability of floors,
foundations, and other supporting structures normally requires analysis by a qualified structural
engineer. See “ABOUT THE FORCES TRANSMITTED BY MILNOR® WASHEREXTRACTORS” (See Table of Contents) for more information.

3. Anchoring Requirements
Machines must be securely anchored to an adequate pedestal base (supplied by others) or a
concrete foundation. The bolt holes in the pedestal top flange should be located and drilled only
after the machine is on site and can be used as a template for bolt hole locations (See the pedestal
base dimensional drawings in this manual). Customer must determine location of bolt holes in
bottom flange if the machine is to be bolted to a foundation. Foundation templates are available
for some machines. Consult Milnor if any obstruction prevents the installation of any anchor bolt.
Properly install anchor bolts at ALL anchor bolt holes on the machine. Anchor bolts cannot
be indiscriminately omitted.
CAUTION 1 : STRIKE AND MACHINE DAMAGE HAZARDS—A machine can “rip”
from its foundation if the machine is not anchored andgrouted in strict accordance with the
awa
dimensional drawing and setting instructions provided in this manual. Damage resulting from
improper installation is not covered by warranty.
• Strictly follow setting instructions and dimensional drawing guidelines when anchoring
and setting this machine.
4. Setting Procedures
1. With the machine near the final location, unbolt the shipping skids.
• If using a pedestal mount (and after observing all precautions), lift machine level with top
of pedestal and slide onto pedestal. Bolt or weld machine to pedestal as desired (See the
pedestal base dimensional drawings for additional information).
• If using a foundation (and after observing all precautions), lift the machine off the skid
and onto temporary blocking. Install anchor bolts, taking care to align the bolts with the
base plates to avoid bolt thread damage. Determine that the minimum clearance
between each base plate and floor surface is as specified (see dimensional drawings).
Shim the machine at temporary blockings to level the machine from left to right and front
to back. Use a carpenter's level along the right and left side of the base to determine if the
machine is level from front to back. Place a level laterally across the base plates to
determine if the machine is level from right to left then see the grouting instructions
below.
CAUTION 2 : MACHINE DAMAGE AND MALFUNCTION HAZARDS—
Tightening anchor bolt fasteners onto spacers (without grout or with improperly applied
grout) twists the machine frame and causes cylinder misalignment.
• Never tighten anchor bolt fasteners before grouting.
• Grout must displace total clearance between base plate and existing foundation
floor. Voids must not exist!
1. After determining the final position of the machine, apply grout between the existing
foundation floor and base, while observing the following considerations:
• All machines are designed to be grouted under the full area of all base plates.
Grout prevents the anchor bolts from distorting the frame when the fasteners are
tightened. Total area under each base plate must be completely filled with grout
(see dimensional drawings). Voids under base plates can magnify vibration,
causing unsatisfactory operation. Use only industrial strength non-shrinking
grout.
• If the grout (after mixing) is of proper consistency, pack or trowel it by hand.
PELLERIN MILNOR CORPORATION
• If the grout (after mixing) is too thin (causing it to flow from under the base
19
pads), install temporary cardboard framing around the pads to retain the grout
until it cures.
2. After the grout has completely cured, raise the machine sufficiently to remove all
temporary blocking and shims. Be careful to avoid disturbing or damaging grout.
3. Lower machine onto grout and tighten all foundation fasteners until they contact the
top of the base plate.
2. Tighten all fasteners evenly, using only one-quarter turn on each fastener before moving to
the next one. While tightening, frequently skip from front to back and right to left to insure
uniform tension. After tightening all fasteners, check each fastener at least twice.

Service Connections
1. General
Required service connections, (depending on machine model and optional features) are as
follows:
1. Piped inlets and outlets (cold water, hot water, flush water, third water, direct steam,
compressed air, liquid supply, and drain to sewer). The sizes and locations of piped inlets and
outlets are shown on the dimensional drawing for your machine.
2. Electrical power connections.
2. Requirements for Piped Connections
Notice 1 : Machine Damage—Plastic water valves can fail if improper connectors are used.
• Only use garden hose bib type connectors.
1. Inlet pressures must be within the minimum/maximum range specified. Pressure outside of
the specified range may cause the machine to operate inefficiently or malfunction and may
damage machine components.
2. Thoroughly flush all water lines before making connections.
3. We recommend installing 40 mesh strainers or filters in front of the cold, hot and third water
valves.
4. When connecting water and steam inlets, always install unions and shut off valves at the
point of connection to permit removal of the machine components for servicing, when
necessary.
5. Suds overflow (if so equipped) to drain, must be vented per plumbing code.
CAUTION 2 : Machine Damage Hazards—Pumped chemical systems, if not properly
installed, can cause corrosion damage.
• See the reference manual for precautions and additional information before making any
chemical connections.

WARNING 3 : Electrocution and Electrical Burn Hazards—Contact with electric powe
can kill or seriously injure you. Electric power is present inside the cabinetry unless the main
machine power disconnect is off.
• Do not service the machine unless qualified and authorized. You must clearly understand
the hazards and how to avoid them.
Notice 4
: Machine Damage—Voltage fluctuations of more than 10% above or below the
specified voltage for your machine can damage electrical components, especially motors.
• Any such conditions should be corrected prior to commissioning your machine.
1. Electrical connections must be made by a competent electrician.
2. Machine must be grounded by connecting 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 on the machine.
3. Stinger leg, if any, must be connected to terminal L3, never to terminals L1 or L2.
4. Make power connections within junction boxes on the rear of the machine.
5. Verify motor rotation (Figure 1). See the operating and trouble shooting manual for more
information. If the cylinder turns in the wrong direction, interchange the wires connected to
L1 and L2. Never move L3 under any circumstances. All motors are phased for proper
rotation. Never attempt to reconnect motors or the motor control devices.
6. Machines ordered for 208/240 volt operation are shipped set for 240 volt operation from the
factory (Figure 2). If the supply voltage is 208 volts, then remove the top, and place the line
voltage switch in the 208 volt position.
