2.0 General Safety

2.1 Guards

Some or all of these conveyors may be fitted with protective covers for the safety of those working around them. To avoid accident or injury, do not operate any conveyor with any of these safety devices loose or removed.

If any of these devices are damaged or missing, take the unit(s) out of operation until the missing/damaged parts can be repaired or replaced. Please contact Marel for replacement parts or for repair consulting.

2.2 Emergency Stop

Some or all of these conveyors may be fitted with Emergency Stop switches in addition to a Main Switch or Service Breaker. Please make sure that all processing, cleaning and service persons are familiar with their location(s) and their use.

Emergency stop switches will cut power to the conveyer motors, and the belt will eventually come to a stop… but may not stop immediately as rollers, belts and items on the belt will still have some momentum with them.

Do not disable, remove or modify any of the installed Emergency Stops. If any modifications become necessary, please consult Marel prior to any such work.

2.3 Regarding Modifications

For the safety of operational personnel and for continued reliable service from your Marel equipment, do not make any modifications. Any modifications to Marel equipment could result in accident or personal injury, and could void any applicable warranties.

3.0 Mounting Instructions

3.1 Mechanical Mounting

Marel Seattle is supervising the installation of this machinery. The conveyors will be erected and bolted to the floor.

3.2 Electrical Mounting

This equipment is delivered ready for connection to the network. Connections are standard from the factory: 230-460V, 60Hz, 3ph. All motors are wired for 460V.

An authorized electrician must perform the connection of this machinery. A wiring diagram may be found in the control box.

After completing all electrical connections, the phase connection (motor direction of rotation) should be checked.

Finally, the motor’s voltage should be checked for correct adaptation to the connected network voltage.

Marel Seattle strongly recommends that a lockable main switch be installed and that this switch be locked into the ‘OFF’ position prior to removal of any safety screens, guards or covers.

3.3 Tools Required

Ordinary hand tools, open end wrenches, socket wrenches, etc. can be used to adjust and maintain this machine. No proprietary tools or equipment are needed.

3.4 Particularly Hazardous Areas

5.0 Maintenance

5.1 Conveyor Maintenance

Conveyor should be maintained by trained personnel only.

After 20 hours operation

a. All bearings are lubricated. Check that lubricating channels are not blocked.

b. Verify proper belt operation. Adjust if necessary.

c. The conveyor must be cleaned daily.

After 100 hours operation

a. While running, lubricate the drive chain (if supplied) with FDA approved lubricant.

b. Check the oil level of gear and variation and fill up, if necessary.

After 500 hours operation

a. Check if bearings are worn. Replace if necessary.

b. Check if sprockets are worn. Replace if necessary.

c. Check whether belt supports are worn. Replace if necessary.

d. Check chain drive (if applicable) between motor and drive shaft. Adjust chain tension and lubricate if necessary.

5.2 Bearing Lubrication

• Use only food-compatible lubricants such as LGFP-2.

• Apply approximately one pump of grease from a standard grease gun to the bearing interior. There should be sufficient remaining space within the housing to allow for even grease distribution during normal operation.

• Overuse of the lubricant is a major cause of bearing failure. Excess grease may cause the bearing to overheat, and can damage bearing seals.

THE TIME SCHEDULE FOR MAINTENANCE MUST BE COMPLIED WITH

CONTINUOUSLY.

5.3 Adjustment of Belt – Modular Plastic Belt Conveyor

Fine adjustments can be made to conveyor belt tension / tracking by first loosening the bearing frame bolts, and then adding or decreasing tension at the take-up bolts at the end of the conveyor. Remember to re-tighten all of the bearing frame bolts before operating the conveyor.

After adjustment, manually pull the belting through the conveyor to confirm proper adjustment. Do this before operating the conveyor motor.

7.0 Damage of Electrical Parts in Connection with Cleaning

1.0 Personal Protection

It is recommended that the cleaning staff wear gloves, waterproof clothes, and boots (type “Wellie”) or something similar during cleaning.

During special cleaning, it is necessary that the cleaning staff wear extra protection. It is often recommended that hearing and face protectors such as visors or glasses are worn.

If detergents are applied which may be injurious to your health and may irritate your airways, then a mask must be worn. This also applies if the dirt to be cleaned might be injurious to your health as well.

Aerosol is particles of water in the air which are formed by using the high pressure cleaner. The higher the water pressure, the finer the aerosol. The finer the aerosol, the longer it will stay in the air and find the ways into your lungs. Aerosol normally carries detergent, disinfectants, and small particles of soil and debris. The accumulated soil and debris to be removed by cleaning may be hazardous to your health also.

2.0 Practical Cleaning

The individual steps depend on the type of equipment to be cleaned.

2.1 Preparation

The room and machinery must be made ready before cleaning is started. The room should be cleared and larger quantities of accumulated soil, debris, and waste bags must be removed. Parts of the machinery that are not to be cleaned must be covered completely before cleaning, i.e. electrical control boxes, etc.

2.2 Removal of large quantities of soil and debris

Larger amounts of soil and debris should first be removed manually by hand, or with the appropriate cleaning utensils.

2.3 Rough cleaning

Remaining soil and debris should first be washed off machines and equipment with water.

Water will soften the remaining hardened debris on the machines and equipment.

2.4 Foaming

Because of the use of special equipment, foam is sprayed on all machines and processing equipment to be cleaned. The foam is made by a foam injector, mixing water and air with the detergent. The foam should be laid out with a maximum pressure of 5 bars (72.5 PSI).

Foam should remain on surfaces for a maximum of 15 minutes or as instructed by the detergent supplier.

2.5 Cleaning

Places that are difficult to access or heavily soiled have to be cleaned manually with a brush or sponge. In order to avoid aerosols, water pressure should never exceed 25 bar (360 PSI) at any time during the cleaning process. The rinsing of all foam covered equipment should be done at a lower pressure, 20 bar (290 PSI), to reduce aerosol-borne detergents as much as possible.

Afterwards, the doors, walls and floors must be cleaned by the higher-pressure cleaner.

The higher-pressure cleaner has to be equipped with cleaning nozzles in order for the water jet to remove all possible remaining debris and foam.

In most instances, it may be necessary to perform cleaning with hot water (47-54°C). Cold water should be used only during the final rinse of sanitizers.

2.6 Control of cleaning

To achieve the best results, the chemicals have to be in direct contact with the bacteria.

Therefore, all equipment must be thoroughly cleaned before disinfecting. This means that all visible soil and debris must be removed off of the machine.

A visual inspection should be performed after cleaning so that the areas that are not sufficiently clean prior to disinfecting can be brought up to acceptable standards.

2.7 Soaking in detergent/acid (if necessary)

To remove remaining scales and deposits, all stainless steel surfaces can be sprayed with a detergent/acid. Soaking is typically performed by applying foam to surfaces, and following with a normal cleaning with soap. The method used will depend on the type of equipment being cleaned. A special foaming nozzle is used to apply the foam.

Helpful Tip: A thin layer of foam will cling to vertical surfaces longer and will work more effectively.

2.8 Disinfecting

To ensure a healthy work environment, and for the best bacteriological results, it is necessary for all equipment to be cleaned properly. Disinfecting kills or inhibits the growth or microorganisms that were not removed during normal cleaning. Disinfecting is done by spraying disinfectant on the surfaces to be treated with a high-pressure cleaner equipped with special cleaning nozzles. (Marel does not provide this equipment.)

2.9 After-rinsing of disinfectants

Following the application of the disinfectant, all disinfected areas must be rinsed a final time with cold water. After this final rinse, equipment is ready for use.

2.10 Final Control

To ensure that equipment and surrounding areas are cleaned properly, a final control of cleaning has to be carried out. The “control” can be either a visual inspection or a bacteriological test. A bacteriological test will give an accurate reading of the bacterial activity as well as an indication of the cleaning standard within a few minutes.

3.0 Detergents and Disinfectants

Detergents are applied to ensure a quick cleaning that is effective as possible. The detergents are made to use in places where cleaning with clean water alone is not satisfactory. Disinfectants are applied to kill ore reduce the reproduction of harmful microorganisms. Disinfectants cannot replace cleaning, as disinfecting only has an effect on cleaned surfaces.

Both detergents and disinfectants can be harmful to the skin. Chemicals or preservative may be absorbed through the skin, increasing risk of skin irritation, an allergic reaction, or other health problems.

Some of the chemicals/detergents have a high pH-value and may irritate the eyes, skin, and throat.

Inhaling of aerosol with particles containing detergents may cause breathlessness or difficulty in breathing. Inhalation of aerosol particles may deposit chemicals in the lungs which may damage their natural purifying process, or may allow the absorption of harmful allergens and irritants into the body.

4.0 Function and Use of Chemicals

Detergents may be classified by function and application, e.g. alkaline and acidic detergents.

Alkaline detergents are typically applied to remove organic materials. These chemicals contain a high pH-value (above pH7), e.g. sodium hydrate or potassium hydroxide. Some bases have corrosive effects on aluminum and zinc, and may also damage other types of surfaces.

Traditional soap is also somewhat alkaline, as a mild base usually based with sodium or potassium.

Acidic detergents (below pH7) are used when lime deposits, rust stains, etc. must also be removed during regular cleaning. Strong chemicals can have an extreme corroding effect on metal surfaces.

Disinfecting kills or reduces the reproduction of microorganisms. Disinfection can be done with chemicals or application of high heat for a period of time. A strong acid or base will also kill bacteria. Remember that chemicals which have a high bacterial effect may also be harmful to people and proper precaution must be exercised at all times.

Strong detergents and disinfectants can also be corrosive to many materials such as iron, copper, and brass. Marel machines and equipment are made of durable materials that are very resistant to the effects of these chemicals when used in correct concentrations and only for the recommended time, after which the machines must be washed down with water. Some machines may contain parts less resistant to damage from these chemicals, and special care must be taken to cover and protect these areas during cleaning.

For daily cleaning, use a chlorinated alkaline detergent. The alkaline will remove fats while the chlorine removes proteins. The chlorine must be between 2% and 7% of the solution before dilution.

Marel recommends consulting your supplier of detergents and disinfectants to choose the correct products and concentrations. Marel assumes no responsibility for damage or injury resulting from improper or incorrect use of the detergents or disinfectants.

5.0 The Physical and Chemical Characteristics

A detergent can be characterized according to physical and chemical characteristics as follows:

1) Product type

2) pH

3) Strength (alkaline or acid)

4) Flammability

Product type: Refers to how the product is applied (for manual use, cleaning with foam, Etc.)

pH-value: One of the characteristics of the detergent and indicates if the detergent is a base or an acid.

Water, which is neutral, has a pH-value of 7. Strong acids, such as hydrochloric acid, have pH-values of 0. Strong bases, such as sodium hydrate, have pH-values from 12-14.

If the pH-value is changed from 7 to 0, then improved cleaning and the removal of rust stains result.

If the pH-value is changed from 7 to 14, then improved cleaning and the removal of vegetable and animal fat result.

Whenever the pH-value is changed from the neutral value of 7, the risk of damages on the skin and airways are increased. A pH-value lower than 3 and higher than 9, will have an irritating effect on your eyes, skin and airways. A pH-value lower than 2 and higher and 12 is normally so strong that the acid will cause burns or wounds on the skin.

To determine the effectiveness of the detergents, the pH-value of the final mixture of detergents must be calculated. The actual pH-value of the concentrated chemical is stated for this purpose.

Strength: Determined by the amount of acid or base the chemical contains and indicates if it is strong or mild.

Flammability: Please follow the declaration of the products or the Product Safety Data

Sheet as provided by the manufacturer of the cleaning products.

6.0 Preparation before the Cleaning of Equipment

It is important that the cleaning staff pays careful attention of the risks of high pressure cleaning with detergents and that those detergents containing aerosols may be injurious to your health.

When the skin is wet and soft, the risk of skin problems are higher and irritating chemicals can penetrate into the skin more easily. To avoid contact between the skin and irritating detergents, gloves must be worn at all times during cleaning. It is recommended that rubber gloves, with a cotton glove worn on the inside for sweat absorption, be used.

At places where disinfecting vapors or aerosols may occur (where high-pressure cleaning is applied), the cleaning staff must use the proper respiratory protective equipment.

Most detergents can irritate the airways when inhaled as an aerosol. Some disinfectants are also known to provoke asthma or sneezing after the inhalation of vapors. In addition, products such as organic chemicals may also irritate the airways. Contact with certain chemicals for long periods of time could cause organ and/or brain damage.

Ventilation of the room alone is not sufficient in protecting the cleaning staff. It is still necessary to use suitable lung protection. During high-pressure cleaning (when aerosol particles occur), the cleaning staff must use appropriate masks or respirators as well as protection for your eyes and skin like gloves, suitable clothing, visors, etc. Always refer to your detergent or cleaning agent manufacturer’s safety and use the instructions for the recommended protective equipment (type of mask or respirator/filter, etc.) and safe practices for the use of these cleaning products.

Pressurized water may cause damage to control panels. Always wipe panel surfaces with alcohol wipes and cover them before washing.

7.0 Damage of Electrical Parts in Connection with Cleaning

ALL ELECTRIC PARTS HAVE TO BE INSULATED AND LOCKED IN THE

OFF-POSITION BEFORE CLEANING!

It is possible to damage the electrical system during cleaning. Typically, the system is damaged by the following:

1) The machine does not start because water has gotten inside the start switch.

2) The machine does not start because there is water elsewhere in the electrical system.

3) There is a short circuit due to insufficient covering of the electrical installation(s).

Remember, the machines cannot start when the repair breaker is in the off-position.

(All machines should be equipped with a repair breaker.)

Some machines can be equipped with a function button so that parts of the machine can function without the risk of personal injury or damage to the function of the machine.
