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 b ath 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

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.

Understanding the Tag Guidelines for the Models Listed Below

MCR09E5MCR12E5MCR18E4MCR16E5MCR27E5-

Several installation guidelines and precautions are displayed symbolically, on tags placed at the appropriate locations on the machine. Some are tie-on and others are adhesive tags. Tie-on tags and white, adhesive tags may be removed after installation. Yellow adhesive tags must remain on the machine.

PELLERIN MILNOR CORPORATION

Understanding the Tag Guidelines for the Models Listed Below

Most tags contain only symbols (no words). A few are worded. The explanations below, start with the tag part number (displayed on the tag). If a tag contains no words, the meaning of the tag is explained below. If the tag contains words, the explanation below simply repeats the wording.

Display or Action	Explanation
	Read the manual before proceeding. This symbol appears on
	most tags. The machine ships with a complete set of manuals.
	The safety, installation, and electrical schematic manuals are
	particularly important to installers.
	B2TAG88005: This carefully built product was tested and
	inspected to meet Milnor performance and quality standards by

B2TAG94081: Motor must rotate in this direction. On single motor washer-extractors and centrifugal extractors, the drive motor must turn in this direction during draining and extraction. This tag is usually wrapped around a motor housing. If the motor turns in the opposite direction when the machine is first tested, the electrical hookup is incorrect and must be reversed as explained in the schematic manual.

B2TAG94097: The cylinder must rotate counterclockwise during draining and extraction (spin) when viewed from here (rear of machine). Otherwise, reverse the electric power connections, as explained in the schematic manual.

B2TAG94099: Do not strike the shell door when fork-lifting.

This can cause the door to leak.

B2T2001013: Hot water connection.

B2T2001014: Cold water connection.

PELLERIN MILNOR CORPORATION

Display or Action	Explanation
	B2T2001016: Flushing water connection. This is the water that
	goes into the supply compartment or pumped chemical manifold
	to flush chemicals into the machine.

B2T2003001: Hold the side of the connection stationary with a wrench as you tighten the connection with another wrench. Otherwise, you may twist components, such as valves, damaging them.

B2T2003002: CAUTION: Equipment and Textile Damage Hazards—Chemicals leaked into the machine, particul arly when it is idle, can destroy machine components and textiles left in the machine.

Ensure the chemical system prevents dribbling, siphoning, or any other unintentional release of chemicals.

Inspect regularly for proper operation and evidence of damage. Consult Milnor document BIWUUI03 “Avoiding Damage f rom Allied Remote Chemical Delivery Systems”.

B2T2008007: Do not exceed 160° Fahrenheit (71° Cels ius) water temperature. Excessive temperature can damage the water valves in this machine. Eliminate water hammer on the water lines to this machine. Water hammer can rupture the water inlet valves on this machine. Follow applicable codes when installing water hammer arresters. Maintain incoming water pressure between 10 and 75 psi (between 0.7 and 5.1 bar). Pressures outside this range can damage the water valves in this machine.

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.

Avoiding Damage From Allied Remote Chemical Delivery Systems

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

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

T.Chemical tank

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.

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.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.

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.

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.

Handling and Setting Procedures for Rigid Mount Washer-Extractors

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” away from its foundation if the machine is not anchored and grouted in strict accordance with the 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 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.

5. Power Connections and Precautions

WARNING 3 : Electrocution and Electrical Burn Hazards—Contact with electric power 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.
