1.1 CONGRATULATIONS ON HAVING CHOSEN DUPLEX MACHINES

These are the main characteristics of DUPLEX machines:

• Cleaning of any type of flooring thanks to a patented centrifugal system which allows dirt

to be recovered automatically and in real time;

• Great ease of handling thanks to the possibility of orientating the handle to change the

cleaning direction;

• Easy access to ‘critical’ points (wall edges, corners, grooves and joints);

• Quite operation.

The experience and know-how gained over our years of production (tens of thousands of machines in various models), the testing and application in different environments 550 PROFESSIONALned with the expertise of our Engineers have allowed us to improve our product constantly. We were able to achieve perfect cleaning results even in the deep grooves in the steps of escalators and reach the side edges, which is still extremely difficult for other escalator cleaning machines.

While cleaning moving escalators, DUPLEX escalator cleaning machines remain still and stable in their position thanks to the especially patented self-guiding system.

Professional models equipped with a full set of accessories and special trolleys have been created from two simpler and cheaper machine models. Apart from facilitating the transport of the appliance within the workplace, these also allow for easy positioning of the machines themselves on the steps of escalators in motion, resulting in minimal cleaning times.

1.2 GENERAL WARNINGS

POWER CORD WITH PLUG

• Check the power cord regularly to see if there is any sign of damage: cracking, peeling, ageing.

• If the power cord is damaged, replace it before using the machine.

• Use a cable of the same type used by the Manufacturer, certified according to “ENEC”

European standards

• Cable replacement must be performed by qualified personnel.

• Avoid any contact of the power cord with the brushes.

IMPORTANT:

Should the power cord get caught under the machine brushes, do not attempt to get it out while the machine is working. Stop operation immediately, remove the plug from the power socket, check the cord. If damaged, do not try to repair it simply putting a tape around it, but replace it.

OTHER WARNINGS

• Ensure the machine does not sit on the brushes when in rest position.

The machine should be supported and raised by the parking support. If this not the case, the machine weight could warp the brushes.

• Be careful not to let the water used for cleaning enter into the plastic casing (gear cover).

Never use pressure washers to clean the Duplex Escalator.

• Unplug the power cord plug from the power socket or battery before any maintenance

intervention.

• Store the machine in a closed and dry place after use.

• The machine is designed and constructed exclusively to clean escalators or moving

walkways. Any other use is considered improper.

WARNING CLEANING AND MAINTENANCE OPERATIONS MUST BE PERFORMED

WITH THE MACHINE DISCONNECTED FROM THE MAINS.

1.3 GENERAL FEATURES AND FUNCTIONS

The DUPLEX brand name is synonymous with double efficiency and distinguishes a machine that actually has a dual function thereby providing numerous advantages for the best possible floor cleaning and hygiene.

The ESCALATOR 550 PROFESSIONAL escalator and moving walkways cleaning machine is fitted with a full set of accessories and moves on two large wheels, which in addition to making its transport easier in the workplace, also allows the machine to be easily positioned on the steps of escalators in motion, and simplify any other operation

necessary for proper use, considerably reducing working times.

The ESCALATOR 550 PROFESSIONAL consists of two separate machine parts: a) machine body and b) 550 cleaning head joined by a tilting bracket which is screwed to the machine body.

a) The machine body in stainless steel is covered by a polypropylene casing,

that incorporates a powerful vacuum cleaner, all electrical controls, a brake to control the machine on the escalators and the detergent tank. b) The machine head is fitted with special stainless steel brush-covering fairings that contain the automatic detergent dispenser system. The patented self-guiding support with grooved wheels keeps the machine cleaning head stable and fixed in the work position. A parking brake ensures the machine is fixed on the step while it is working on escalators in motion. The tilting bracket lifts the cleaning head and makes its reversal easier to allow the

cleaning of the right and left sides of the escalator.

1.7 HOW TO USE

WARNING Before inserting the cable plug into a power point, which must be

earthed, make sure the ON switches of the wet and dry vacuum cleaner

and the machine are in the “OFF” position.

IT IS RECOMMENDED THAT YOU LUBRICATE THE CONVEYOR BELTS WITH COMMERCIAL SILICONE SPRAY BEFORE STARTING UP THE MACHINE.

HOW TO CLEAN AND WASH ESCALATORS AND MOVING WALKWAYS

Fit the special brushes provided, with their equidistant bristles to reach right down into the tracks forming the stair tread of the escalators.

The pitch of these tracks or channels may vary from manufacturer to manufacturer. Optional OTIS/KONE – THYSSEN –

SCHINDLER/MITSUBISHI brushes are available upon request.

Figure 1.6

The brushes of the DUPLEX ESCALATOR

550 PROFESSIONAL machines are made from a special plastic material with no abrasive

coating, ensuring that no damage is caused to the metal steps of escalators or moving walkways.

WARNING: Good cleaning results and a longer lifespan of the brushes can only be

achieved if the bristles can enter into the stair tracks or channels precisely. The use of inappropriate brushes cannot only compromise the cleaning quality but also damage the brushes.

AUTOMATIC MOTOR PROTECTION "MOTOR PROTECTOR" MP

The “Motor Protector” is a safety device which stops the machine in case conditions occur

that overload the electric motor (e.g. foreign bodies caught in the brushes which can prevent their rotation, poor supply of power, overheating, etc.).

WARNING: Disconnect the machine from the power socket before removing any

foreign bodies caught in the brushes.

After checking and possibly eliminating the cause which led to motor overload, press the “Motor protector” button (after about 60 seconds) to restore machine operation.

DUPLEX ESCALATOR 550 PROFESSIONAL

1.8 HOW TO WASH ESCALATORS AND MOVING WALKWAYS

1st PHASE - DRY BRUSHING

IMPORTANT: All dry dust will be sucked up using this procedure, which is essential

to prevent dust from turning into mud when the washing phase is carried out. We recommend to pour the water into the central recovery tank during the suction phase.

For better cleaning results it is recommended to have the escalators or moving walkways move towards the operator.

1. Position the machine at the foot of the escalator (preferably on the bottom floor);

2. Position the machine on the first step making sure that the narrow side is lined up against

the edge of the step, and that the stabilising wheels are in the channels, regardless of the position of the machine, which can either be on the right or the left hand side;

3. Remove the head of the wet and dry vacuum cleaner and fill the tank up with water to a

height of about 10cm from the bottom (important for the filtering of dust);

4. Insert the suction hose into the appropriate opening in the cover (16) supplied;

5. MU ”Mop-Up”: Conveyor belt activator. Keep this switch in the low position (7) for the

simultaneous recovery of dirt.

Figure 1.9

Page 16

DUPLEX ESCALATOR 550 PROFESSIONAL

6. Turn on the motor and the wet and dry vacuum cleaner.

7. Activate the escalator or moving walkway (always moving towards the operator);

8. Grab the machine firmly and make the escalator (or walkway) complete at least three full

rotations;

9. Then, lift the machine cleaning head, turn off the motors and empty any dust collected

from the recovery tank.

10. Move the machine to the other side of the step and carry out the same procedure,

following the same sequence as above.

Figure 1.10

Page 17

DUPLEX ESCALATOR 550 PROFESSIONAL

2nd PHASE - WASHING For better cleaning results it is recommended to always have the escalators or moving

walkways move towards the operator.

1. Prepare a detergent solution consisting 95% of water and 5% of Detex (specific product to

clean escalators - see technical sheet).

2. Fill the tank with this solution via the tank opening for the detergent.

IMPORTANT: DETEX is a product expressly designed and developed for the cleaning

of escalators or moving walkways. It does NOT damage surfaces, metal parts or components and rubber or plastic components and the machine paintwork. The use of products other than those specified will invalidate any

warranty and relieve the manufacturer from any liability deriving from damage caused by the use of unsuitable products.

3. Insert the hose of the wet and dry vacuum cleaner into the opening in the recovery tank

cover (16);

4. Attach the pipe for detergent dispensing (18) into the snap-connector;

5. Position the machine on the first step;

6. Start the brush and vacuum cleaner motors.

7. Turn on the pump switch, grip the trolley handle firmly;

8. Activate the escalator or moving walkway (preferably moving towards the operator).

9. Make the escalator rotate several times until all dirt has been fully removed.

10. Turn off the pump and make a few dry rotations in order to finish the work. Then let the

escalator dry completely.

Figure 1.11

Page 18

DUPLEX ESCALATOR 550 PROFESSIONAL

11. After having stopped the motor, reverse the position of the machine and follow the same

sequence on the opposite side.

During the washing procedure it may be necessary to stop the machine and empty the dirty liquid recovery tank. This operation is made easier using the wet and dry vacuum cleaner supplied, which sucks up the dirty water directly from the recovery tank without requiring it to be removed from its seat.

IMPORTANT: It is important for all three stabilising

guide wheels to be inserted into the same channel or track, otherwise the machine could move crossways and work in an irregular manner.

Should the escalator or moving walkway be covered in

Figure

1.12

layers of dirt and muck due to wear, more frequent and long washing may be required. Once the escalators' and moving walkways' optimal condition has been restored, routine maintenance gets easier, quicker and cheaper.

The positioning of the Duplex Escalator 550 PROFESSIONAL on escalator steps or moving walkway requires a certain dexterity and ability that the operator can acquire only after carrying out various washing operations.

TIP: To check whether the escalator/moving walkway has completed a full

rotation, and consequently a full washing session, apply a sticker to the rubber handrail in the same direction of rotation. As the sticker reappears it means that the rotation has completed.

3rd PHASE - SOAKING (optional)

Very often, older escalators or walkways present greasy black deposits in the corners of the steps which have built up over the years following the use of lubricants for the escalator mechanisms that became impregnated with dust and dirt.

In this case the washing operation may be preceded by a preventive soaking phase. We recommend that you use a standard pressure spray pump. Fill it with the same DETEX product, either diluted or undiluted, and spray the product over the entire surface to be treated evenly while the walkway is running.

Page 19

DUPLEX ESCALATOR 550 PROFESSIONAL

1.9 GENERAL MAINTENANCE

WARNING: During cleaning and maintenance operations the machine must always

be disconnected from the mains.

WARNING: Never use a pressure washer for cleaning operations.

The procedures described below must be carried out after each use of the machine.

CLEANING THE MACHINE

• Remove and thoroughly clean the casings covering the brushes, the recovery tank and

the detergent dispensers with water.

• Remove the machine head from the trolley and clean its interior with water.

• Clean the lower section of the machine laying the machine on its side (Duplex logo facing

upwards), taking care not to let water get inside the casing. Leave to dry.

• Wash the inside of the wet and dry vacuum cleaner with running water, rinse and empty.

• Lubricate the two rubber conveyor belts evenly using Duplex silicone spray.

CLEANING AND MAINTENANCE OF THE BRUSHES

DUPLEX brushes require little routine maintenance. The high rotation speed during cleaning manages to centrifugate dirt and keep them efficient at all times. However, check their status and clean them, if necessary.

WARNING: Remove the plug from the power socket before cleaning the brushes.

Page 20

DUPLEX ESCALATOR 550 PROFESSIONAL

ROUTINE MAINTENANCE

In addition to cleaning, it is necessary to perform the following operations periodically:

• Remove the brushes from the machine (see following section);

• Dip them in a container with cold or lukewarm water and let them soak for a few hours;

• Stir and rinse the brushes well;

• Re-fit the brushes in reversed position in relation to the one they had before. This is

necessary as the bristles tend to bend when the brushes always rotate in the same direction.

The mechanical parts of the DUPLEX ESCALATOR do not require any particular maintenance.

HOW TO REMOVE THE BRUSHES

1. Unscrew the two screws anchoring the stainless steel casing using the supplied wrench.

2. Remove the brushes.
