WARNINGS BEFORE USING THE MACHINE IT IS RECOMMENDED CAREFULLY READING ALL THE INSTRUCTIONS IN THIS MANUAL INTRODUCTION DUPLEX is a machine for washing floors equipped with an original automatic system for recovering the dirty water. Its special manufacturing characteristics endow it with advantages and performances which make it stand out from all other types of floor washer.
DUPLEX, covered by international patents, is always ready for use, and extremely user-friendly due to moving about on four sliding castors which drop down automatically. We invite you to follow the use and maintenance instructions with care. This device is suitable for commercial use, for example in hotels, hospitals, factories, shops, offices and hire services, as well as for normal use in the home. Warning: this device is destined for use exclusively with the brushes specified by the manufacturer.
It washes and dries floors in the following materials: Ceramics - rubber - tapisum - cotto - carpet - klinker - cement - wood - plastic - PVC – epoxy resin - brick - porphyry - marble - granite – relief ceramics bullonato - pietra serena - linoleum - porcelain - glass – artistic mosaics rugs - quartz - graniglia - grès.
ASSEMBLING THE MACHINE The machine is shipped in a cardboard box. After receiving the package the user must carry out the assembly of all the parts that for space reasons have been disassembled before being shipped.
ASSEMBLING THE HANDLE Insert the elbow of the handle into the housing of the jointed elbow. Tighten the two screws with the screwdriver supplied and tighten well. (fig. 1) Fig. 1 Assemble the handgrip if the handle by pushing it through the connecting casing and make sure to point the screws inwards with the cable-holder facing towards the bottom. Screw up the three screws with the same screwdriver supplied. (fig. 2). Fig. 2 The assembled handle must be as illustrated in the drawing to the right. Fig.
Make sure that the same feelers remain flush with the side panel when the lever is not pulled down. (fig. 4) If the feelers protrude it may be impossible to insert or extract the tanks containing the liquid from their housings. à Fig. 4 LOADING THE WASHING LIQUID Two tanks contain the solution for washing, both of these must always be at the same level. The tanks can be filled either by pouring water in from a jug, (fig. 5) or by placing the tanks themselves under a tap as they are easy to remove. Fig.
STARTING UP Before inserting the plug of the connecting cable into a power point equipped with earthing, make sure that the handle is in the Rest position (perfectly vertical) and that the RT register is in the Rest Translation position. (fig. 6) MU This register can be shifted to any one of the four preselected RT positions, which will establish the different positions the brushes will adopt on the floor. (fig. 7) Fig.
Take hold of the handle and lower it slowly to one of the two sides, the machine will start up and the revolving brushes will start revolving on the floor. (fig. 8) Move the machine slowly forwards, going over the same washing path with the recovery device MU (MOP UP) inserted (lever pulled downwards). (fig. 6) Let the liquid move downwards by activating the lever underneath the handle at brief intervals and only when the machine is moving forwards, taking care not to flood the floor. Fig.
Figures 10, 11 and 12 illustrate how DUPLEX works as far as the edges of the skirting boards of the walls or the furniture and how it enters into restricted spaces. Fig. 10 Fig. 11 Fig. 12 DUPLEX works in two directions (backwards and forwards) without having to shift it from its original position as it is sufficient to move the handle from right to left or from left to right in order to reach the opposite sides of every room.
INSTRUCTION FOR WASHING FLOORS Fig. 13 2. 3. 4. Position start nd 2 phase Position start st 1 phase 1. For the first phase move forwards from the Start position towards the corner as indicated in fig. 13. Make the machine move backwards and continue to clean the same “lane”, thus returning to the starting off point. From the starting-off point shift onto the second washing path, slightly overlapping the path that has been cleaned previously.
BRUSHES “Use original DUPLEX brushes exclusively ” The original DUPLEX brushes are tested and balanced individually with special electronic instruments and guarantee the absence of vibrations that could generate damaging mechanical stress for the machine and the floors. The use characteristics of the brushes can be recognised via the colour: Light grey; Black; Black/hard; Yellow; Brown; Scotch-brite (compact); Dark grey (Tynex).
Brown horsehair brushes: The polishing of smooth surfaces is carried out after having evenly distributed a thin layer of liquid wax over the floor. Wait for the wax to dry completely before polishing. Set the register to the MU (Mop-Up) position towards the top. The RT register must be set to the “Heavy Wash” or “Delicate Wash” positions, then move the machine forwards and backwards in order to polish the floor. Do not use the machine for spreading the wax.
The two tanks must be filled with the special product mixed with water in the proportions and according to the instructions on the outside of the bottles, after which the same system is followed as for the normal washing operation. (The special product can be ordered for home delivery). It is possible to obtain a greater brilliance by passing the Duplex over the floor fitted with the horsehair or Scotch-brite brushes.
This procedure can be carried out with every type of brush supplied except the brown horsehair brushes. After washing particularly dirty floors and before carrying out any other type of process on delicate floors, clean the brushes and the machine well (see pages 17 and 19). STOPPING THE OPERATIONS Every time the handle is moved into the vertical REST position the machine will immediately come to a halt. Each time the machine stops, it will be necessary to move the register (fig.
AUTOMATIC “MOTOR PROTECTOR” In the event of certain conditions existing which could overload the electric motor (foreign bodies in the brushes that could block their rotation, power supply fluctuations, overheating etc.), the “Motor Protector” will intervene and stop the machine. Fig. 14 After waiting for approximately 60 seconds, restore the machine operation by pressing the same “Motor Protector” button.
HOW TO REMOVE THE BRUSHES Use the screwdriver supplied to remove the two screws located on the stainless side panel. (fig. 15) Fig. 15 Extract the two brushes together with the side panel. fig. 16) Fig. 16 Separate the two brushes from the side panel itself. In the case of the brushes being deformed (due to wear and tear of the same), they may generate jumps and vibrations. In this case contact the assistance centre.
CLEANING THE MACHINE Remove the three tanks (fig. 17). Use a damp sponge to carefully clean the rubber conveyor belts and every part of the machine itself. Use a brush to remove every residue of dirt from all the corners. Fig. 17 Dry well. Do not use high pressure water jet machines to wash the machine. CLEANING THE TANKS The three thanks (the dirty water recovery one and the two containing the clean water and the detergent) can be washed in running water under the tap.
Clean the holes of the nozzles with a needle (fig. 20). Always keep the two scrapers of the recovery tank clean. This procedure should be carried out after every machine operation. Fig. 20 GENERAL MAINTENANCE The mechanical parts of the DUPLEX do not require periodic maintenance as their gearings all run on bearings. IMPORTANT PRECAUTIONS At times it may happen that the electric cord gets tangled up underneath the brushes of the machine.
As with all electrical products, the machine must be stored in a dry environment after use. The machine is designed exclusively for washing floors and must not be used for other purposes. When the machine is no longer capable of functioning correctly after many years of service, follow the instructions on page 23 for rendering it unserviceable. During the cleaning and maintenance operations, it is compulsory for the machine to be disconnected from the electric power supply.
It vibrates - The brushes are deformed or dirty, follow the instructions on page 18. The liquid runs out continuously - The nozzles have not re-entered (fig. 4), in this case they restrict the tanks which cannot be extracted and as a result the valves remain open.
HOW TO DISMANTLE THE MACHINE At the time of demolishing the machine it is sufficient to observe the following instructions : · disconnect the electrical connections and entrust the dismantling operations to qualified and authorised personnel. DIFFERENTIATED SUBDIVISION OF THE MATERIALS Electric components : Material that can be disposed of with the urban waste collection, in compliance with the legal provisions in the country of use.
