ABOUT THIS MANUAL
Scope—This instruction manual is intended to provide preventive maintenance procedures,
service procedures, and mechanical parts identification for all Milnor® 30015, 30020, and 30022
model rigid mount washer-extractors. Measurements are in commonly used US and metric units
unless otherwise noted.
See the appropriate programming, operating, and troubleshooting manual for information on the
control system. See the schematic manual for electrical parts identification and electrical
troubleshooting.
Manual Number/Date Code (When To Discard or Save)—The manual
number/date code is located on the inside front cover, upper right corner just above the manual
name. Whenever the manual is reprinted with new information, part of this number changes. If
the date code after the “/” changes, the new version applies to all machines covered by the
old version, but is improved— thus the old version can be discarded. If the manual number
before the “/” changes, the new manual covers only new machines. Example: Discard
MATMODELAE/8739CV when MATMODELAE/8739DV is received (minor improvements).
Also, discard MATMODELAE/8739DV when MATMODELAE/8746AV is received (major
improvements). But keep MATMODELAE/8746FV when MATMODELBE/8815AV is
received, since the new manual no longer applies to machines originally shipped with the old
manual.
Documents and Change Bars—The individual documents comprising this manual use the
same revision criteria as the manual. Text documents also display change bars. Example: When
sectionMSOP0599AE/9135BV becomes MSOP0599AE/9135CV, change bars with the letter
“C” appear next to all changes for this revision. For a major rewrite (e.g.,
MSOP0599AE/92

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

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
the specific machines.

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
15
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 unin ten ti 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.

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.

Preventive Maintenance
1. Lubrication Guidelines
As required by the warranty, to ensure safe operation, and to achieve optimum performance and
service life from Milnor® washer-extractors, the schedules, instructions, and precautions herein
must be strictly followed.
WARNING 1 : Entangle and Crush Hazard—Belts and pulleys can entangle and crush
body parts.
• Lock OFF and tag out power at the wall disconnect before servicing, except where
specifically instructed otherwise in this section.
• Insure belt and pulley guards are in place during service procedures.
• Permit only qualified maintenance personnel to perform these procedures.
2. 36021C4E Main Bearing Maintenance
36021C4E main bearing housings are oil-filled and require periodic draining and refilling (see
below).
See the appropriate “MAIN BEARING ASSEMBLY” (see Table of Contents) during this
procedure.
1. Remove the drain plug on the bottom of the main bearing housing and allow the bearing
housing to drain completely (Figure 1). Inspect the leak-off, drained oil, and magnetic drain
plug for water and/or metal particles. Install the drain plug. Water and/or metal particles can
indicate worn or damaged seals and bearings.
2. Locate the two 1/2" plastic tubes secured to the electrical control chassis (Figure 2). Clean the
surrounding area and remove the cork stoppers from each.
3. Strictly following lubrication specifications, refill the bearing housing. After refilling the
bearing housing, re-install the cork stoppers and clean any excess lubricant from the machine.
