WASHER-EXTRACTORS AND CENTRIFUGAL EXTRACTORS
General Safety Requirements
Ê
(specific warnings, next page and throughout manual)
Incorrect installation, neglected preventive maintenance, abuse, and/or improper repairs or changes to the
machine can cause unsafe operation and personal injuries, such as multiple fractures, amputations, or death. The
owner or his selected representative (owner/user) is responsible for understanding and ensuring the proper operation
and maintenance of the machine. The owner/user must familiarize himself with the contents of all machine instruction manuals. The owner/user should direct any questions about these instructions to a Milnor® dealer or the Milnor® Service department.
Most regulatory authorities (including OSHA in the USA) hold the owner/user ultimately responsible for
maintaining a safe working environment. Therefore, the owner/user must do the following:
•
•
•
•
recognize all foreseeable safety hazards within his facility and take actions to protect his personnel,
equipment, and facility
require that personnel are familiar with all functional and safety aspects of the machine
ensure safety devices installed on the machine are in place and properly maintained
ensure all machine parts and assemblies are properly maintained.
Hazards During Installation
Ê
ELECTROCUTION HAZARD—Contact with high voltages can kill or seriously
injure you.
☞ All electrical connections must be made by a competent electrician.
EQUIPMENT DAMAGE HAZARD—Machine can be damaged if shipping restraints are improperly utilized. These include various bolts, brackets, and
safety stands (painted red), brake blocks and the vibration safety switch (tie
wrapped).
☞ DO NOT remove shipping restraints until installation is complete.
☞ DO remove all shipping restraints before operating machine.
Hazards During Service and Maintenance
Ê
Laundry Facility—Provide a supporting floor that is strong and rigid enough to support--with a reasonable
Ë
safety factor and without undue or objectionable deflection--the weight of the fully loaded machine and the forces
transmitted by it during operation. (For washer-extractors, see “ABOUT THE FORCES TRANSMITTED BY MILNOR® WASHER-EXTRACTORS.”) Provide sufficient clearance for machine movement. Provide any safety
guards, fences, restraints, devices, and verbal and/or posted restrictions necessary to prevent personnel, machines,
or other moving machinery from accessing the machine or its path. Provide adequate ventilation to carry away heat
and vapors. Ensure service connections to installed machines meet local and national safety standards, especially
regarding the electrical disconnect (see the National Electric Code). Prominently post safety information, including
signs showing the source of electrical disconnect.
ELECTROCUTION HAZARD—High voltage is present inside electric boxes, motors and many other components. Power switches on machine control panels
disable only control circuit power in certain boxes. You can be killed or seriously injured on contact with high voltage.
☞ Lock OFF and tag out power at the wall disconnect before servicing, except where specifically instructed otherwise in this manual.
Personnel—Inform personnel about hazard avoidance and the importance of care and common sense. Provide
Ë
personnel with the safety and operating instructions that apply to them. Verify that personnel use proper safety and
operating procedures. Verify that personnel understand and abide by point-of-hazard tags on the machine and procedure-specific precautions in the instruction manuals.
ENTANGLE AND CRUSH HAZARD—Belts and pulleys can entangle and crush
body parts.
Safety Devices—Ensure that no one eliminates or disables any safety device on the machine or in this facility.
Ë
☞ Lock OFF and tag out power at the wall disconnect before servicing, except
where specifically instructed otherwise in this manual.
Do not allow machine to be used with any missing guard or cover. Service any failing or malfunctioning device
before operating the machine.
Maintenance—Ensure the machine is inspected and serviced in accordance with the norms of good practice and
Ë
with the preventive maintenance schedule. Replace belts, pulleys, brake shoes/disks, clutch plates/tires, rollers,
seals, alignment guides, etc. before they are severely worn. Immediately investigate any evidence of impending
failure and make needed repairs (e.g., cylinder, shell, or frame cracks; drive components such as motors, gear boxes,
bearings, etc., whining, grinding, smoking, or becoming abnormally hot; bending or cracking of cylinder, shell,
frame, etc.; leaking seals, hoses, valves, etc.) Do not permit service or maintenance by unqualified personnel.

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
flexibly-mounted 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
on-grade 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
11
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
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.

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

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® batch
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).
Figure 1: Pumped Chemical Inlets on CBW Batch Washer
Note 1: Misuse of laundering chemicals (such as injecting excessive concentrations of chlorine bleach or
permitting acid sours to react with hypo chlorite) due to incorrect formulation can also be hazardous.
Information pertinent to chemical use is provided elsewhere in the product manuals.
1.
How a Chemical System Can Damage the Machine It Serves
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.
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
PELLERIN MILNOR CORPORATION
18
Avoiding Damage From Allied Remote Chemical Delivery Systems
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

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 chemical in the tank above the siphon level (S), and indicated by
shading, will flow into the machine.

Siphon level. Shading indicates the chemical delivery line and tank content that can siphon into
the machine.

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
21
3.4.
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.

Guarding Against Leaks
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.

To protect against lateral creeping of the machine during operation (due to vibration),
roughen the area of the floor where the grout will be applied. Anchor bolts are required.
1. With the machine near the final location, unbolt the shipping skids. Observing all
precautions, lift the machine off its skids and lower the machine onto blocking. Shim the
blocking until the machine is level and approximately l" (25) clearance exists under each base
pad. Install anchor bolts as shown on the dimensional drawing, but do not tighten bolts until
grout is completely dry.
2. Apply grout between the existing foundation floor and the base pads, observing the following
considerations:
• Use only industrial strength non-shrinking grout. Pack or trowel by hand.
• If the grout after mixing is too thin (causing it to flow from under the base pads) install
temporary cardboard framing around pads to retain the grout until it cures.

magnify vibration and cause unsatisfactory operation.
• Grout must displace total clearance between base pads and existing foundation
floor.
• Voids must not exist.
3. Tighten anchor bolts evenly using only one-quarter turn on each bolt 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 bolts, check each bolt at least twice during the first week
of operation.

=^cXRT # ) <PRWX]T 3P\PVT 7PiPaSb—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.
The customer must furnish a remotely mounted disconnect switch with lag type fuses or circuit
breakers, and wiring between the electrical service box and the junction box on the machine. The
sizes of these fuses and wires, along with the motor fuses supplied with the machine, depend on
the machine voltage. See the fuse and wire sizing information in the schematic manual and on the
machine nameplate. See dimensional drawings in this manual for electrical connection locations.
1. Electrical connections must be made by a competent electrician.
2. See fuse and wire sizing information in the schematic manual and on the machine nameplate.
If the wire runs more than 50 feet, increase by one wire size for each additional 50 feet.
3. Only use Bussman Fusatron FRN (up to 250V), FRS (up to 600V), or similar lag fuses. The
nameplate fuse sizes must not be applied to standard fuses.
4. Stinger leg, if any, must be connected to terminal L3, never to terminals L1 or L2.
5. Make power and liquid supply electrical connections within junction boxes on the rear of the
machine.
6. 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.
