INTRODUCTION

This manual is an integral part of the brush, and it contains all the information necessary for its operation and maintenance.

It is necessary to carefully read this manual and follow the instructions contained in it.

This manual, or a copy of it, must always be kept on hand for the operator to consult whenever necessary.

We also advise you to contact the manufacturer for any information, replacement parts, or

  accessories you might require.

PRESENTATION  

 

The  rotating  roller  brush  was  designed  and  built  to  clean  solar  panels.  

Specifically,  when  used  as  intended  and  under  the  conditions  foreseen  by  the  manufacturer,  it   performs  the  operations  of  brushing  and  washing  solar  panels.  

It   is   a   mobile,   hand-­‐operated   brush;   that   is,   it   was   designed   to   be   positioned   and   operated   manually  on  the  surface  to  be  cleaned.  

   

To   achieve   the   best   performance,   we   have   written   this   manual,   which   we   ask   you   to   read  

  carefully  and  observe  every  time  you  use  the  brush.  

 

In  the  case  of  a  change  of  ownership,  the  seller  has  the  obligation  to  deliver  this  manual  to  the   new  owner.  

 

Thank  you  for  choosing  our  product;  we  wish  you  the  best  in  your  work.

INTENDED  USE  

 

The  brush  is  intended  for  professional  use,  that  is,  for  those  people  who  have  the  necessary   technical,  regulatory,  and  legislative  experience  and  who  are  able  to  perform  the  operations  

 

  necessary  for  operating  and  maintaining  the  unit.  

Using   the   brush   requires   special   skills   and   technical   training   as   well   as   a   deep   sense   of   responsibility.  

Operators   must   possess   specific   psychophysical   qualifications   to   be   suitable   for   performing   this  work;  therefore,  the  brush  can  be  used  only  by  authorized  personnel.  

 

The   brush’s   intended   use   is   primarily   for   cleaning   solar   panels   and   washable   surfaces   in   general.   It   functions   by   means   of   devices   that   put   the   water   supplied   to   the   brush   under   pressure.  

 

The  following  are  examples  of  improper  use  of  the  unit:  

-­‐  Using  the  unit  in  the  rain,  at  freezing  temperatures,  or  when  strong  winds  are  present.  

-­‐  Cleaning  surfaces  that  are  not  suitable  for  treatment  with  this  unit.  

-­‐  Using  the  brush  to  clean  animals,  people,  etc.  

-­‐  Changing  accessories  while  the  brush  is  running.  

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

-­‐  Leaving  the  brush  untended  while  it  is  running.  

-­‐  Using  the  brush  without  protection.  

 

-­‐  Using  the  brush  under  conditions  of  poor  lighting.  

 

 

Use   only   original   accessories,   because   they   offer   the   best   quality   and   safety   features.   If   original  accessories  are  not  used,  the  manufacturer  will  be  relieved  of  all  responsibility.

PRODUCTS TREATED – HANDLED OR GENERATED

The products treated with the brush that is the object of this manual must consist of solar panels comprised of modules with a maximum tilt of 35°.

Verify in the photovoltaic system’s operating manual the type of brushes that can be used for cleaning it, so as not to cause abrasions on the panels’ film.

The surfaces to be treated must be as flat as possible.

It is important to avoid all operating situations that could cause repeated and unexpected stops of the brush’s rotation, such as those specified below.

In the case of surfaces comprised of panels, the maximum distance between them must be 3 cm to prevent the unit from dropping into the empty space between one panel and the next.

The surfaces must be as free as possible of protruding bodies such as long screws, brackets, and terminals, which could obstruct brush rotation or rip out its bristles.

The brush is not designed to withstand heavy accidental impacts, such as those caused by being dropped, or those that are less intense but repetitive, such as those resulting from operating in stepped areas.

It is also very important that the operating pressure not exceed the maximum value indicated in the “Technical Specifications” in order to prevent excessively high rotation speeds from causing premature wear of the unit’s mechanical parts.

When not in operation, never allow the unit’s weight to rest on the rollers’ bristles so as not to bend them.

Damage or breakage resulting from the improper use of the brush (as described above) cannot be repaired under warranty.

USE ONLY IN FENCED AND WELL-DEFINED AREAS IN ORDER TO AVOID

CAUSING INJURY TO PEOPLE OR MATERIAL DAMAGE IN CASE THE BRUSH FALLS

FROM THE RAISED OPERATING AREA IF IT SHOULD BECOME ACCIDENTALLY

DETACHED FROM THE CONTROL ROD.

5

The work environment must be in compliance with the requirements of Directive

89/654/EEC. There must not be any foreign objects present in the work area. The lighting must be checked periodically and maintained in good working order.

The employer, in observance of Directive 89/391/EEC regarding the implementation of measures to promote improvements in workers’ safety and health during work, must eliminate or reduce the residual risks as specified in this manual.

LIGHTING

The environment in which the brush is to be used must be sufficiently lighted to allow a visual check of the brush and the pictograms affixed to it.

OPERATING AT A HEIGHT

An operator who uses the brush at a height (roofs, platforms, scaffolding, etc.) must be trained for this use and must be knowledgeable of the rules of operation and the safety equipment to be used, in order to be able to operate safely in these types of work environments and to avoid dangerous accidents.

6

OPERATING PRINCIPLE

By employing the water pressure to hydrokinetically induce the rotation of the brush and, therefore, the cleaning action of the bristles, this system, which is hand operated by the operator, results in considerable time savings in the cleaning operation performed on solar panels when compared to traditional fixed brushes.

SAFETY RULES

WARNING: DO NOT DO THE FOLLOWING

It is prohibited to use personnel who are untrained or who have not read and understood the instructions listed in this manual.

Do not use the brush to perform work in closed spaces.

Do not use the brush for work in high places if the operator does not know the relevant safety rules or rules of operation.

DO NOT use the brush at night or under conditions of poor lighting.

DO NOT use the unit with fluids that are flammable or toxic or whose specifications are incompatible with the proper functioning of the unit.

DANGER OF EXPLOSION OR POISONING

It is prohibited to use the unit in a potentially flammable or explosive atmosphere.

DO NOT direct the brush against people or animals, and do not place your hands or any other parts of your body in front of or under the brush while it is rotating.

DANGER OF INJURY

DO NOT clean any solar panels without first having disconnected the power to the system.

DANGER OF ELECTRIC SHOCK

The unit CANNOT be operated by minors under 18 years of age or by those who are unfit to operate it.

DANGER OF ACCIDENTS

DO NOT use the brush if the high-pressure hose is damaged.

DANGER OF BURSTING

DANGER OF ACCIDENTS

7

DO NOT leave the brush untended.

DANGER OF ACCIDENTS

It is prohibited to use non-original accessories or accessories not intended for your specific model.

It is prohibited to make any modifications to the brush. Making modifications nullifies the declaration of conformity and relieves the manufacturer of civil and criminal responsibility.

IMPORTANT: DO THE FOLLOWING

An operator who uses the brush at a height (roofs, platforms, scaffolding, etc.) must be trained for this use and must be knowledgeable of the rules of operation and the safety equipment to be used, in order to be able to operate safely in these types of work environments and to avoid dangerous accidents.

While the brush is rotating, it can fling objects; therefore, it is necessary to WEAR protective clothing and safety goggles.

DANGER OF INJURY

DISCHARGE the residual pressure before detaching the hose from the brush.

DANGER OF INJURY

VERIFY, before each use and periodically, that the screws are tight and that the unit’s component parts are in good condition; check whether there are broken or worn parts.

DANGER OF ACCIDENTS

KEEP people and animals at a minimum distance of 15 m from the operating zone.

DANGER OF INJURY

Perform all the work and maintenance phases in conformity with current occupational safety and health regulations.

CLEANING

It is prohibited to clean, oil, or apply grease, by hand, to the brush’s parts and components while they are in motion, unless this is required due to particular technical requirements. In the latter case appropriate equipment must be used in order to prevent all danger.

Workers must be made aware of this by means of clearly visible notices.

Below are indicated cleaning operations that can be performed by maintenance

personnel, who possess professional qualifications, as specified in this section.

Normally some cleaning operations can be performed by the operator; these are normal operations performed on the brush’s exterior that require the use of simple personal protective equipment.

The cleaning operations of the unit’s internal parts must be performed by the maintenance service.

To prevent inopportune and dangerous unintended activation of the unit or improper modifications of any type to the brush, even those that are inadvertent or accidental, it is preferable that the cleaning be performed by the same personnel who operate the machinery, rather than by different personnel, who cannot guarantee to observe all the recommendations contained in this manual.

All the cleaning operations must be performed only after having isolated and removed

the unit from external power sources.

Never use gasoline, solvents, or flammable and/or corrosive fluids to clean the brush or its on-board components.

Use commercially available and approved nonflammable and nontoxic solvents.

Observe the instructions for use and adopt any personal protective equipment advised by the supplier of these substances.

When the operations have been completed, all the fixed covers must be put back in place and locked into position.

When finished using

Clean the brush’s external parts with a soft dry cloth that does not leave fibers on the surface.

Avoid using alcohol, gasoline, solvents, and any other type of detergent.

Clean the unit exclusively with an absolutely neutral and non-foaming water-based detergent.

Do not use any of the following for any reason whatsoever: abrasive products, colored substances, metal scouring pads, brushes, scrapers, etc.

OPERATING CYCLE

1 Connect the brush to the telescopic lance.

2 Position the brush on the surface to be cleaned.

3 Open the water valve on the telescopic lance.

 

4 Begin cleaning the surface.

STOPPING  THE  CYCLE  -­  TURNING  OFF  

 

1  Close  the  telescopic  lance’s  valve.  

2  Turn  off  the  water  supply.  

3 Open the telescopic lance’s valve to  discharge  the  residual  pressure.  

CLEANING COATED OR PAINTED SURFACES

Using water on glued parts may cause them to become detached. Do not use the brush on wood floors or parquet that are not well-sealed.

Be careful when cleaning doors, parquet, painted surfaces or surfaces coated with synthetic products, and aluminum panels.

Before using the brush, we advise performing a test on a portion of the surface that is not in view, to prevent damage or alterations during cleaning.

CLEANING WINDOWS AND SOLAR PANELS

DO NOT clean any solar panels without first having disconnected the power to the system.

MAINTENANCE  

 

Perform all the work and maintenance phases in conformity with current occupational safety and health regulations.

Perform all the maintenance operations while the unit is disconnected and after ensuring that the brush is in an easily accessible and stable position.

 

Only   what   is   authorized   in   this   operating   manual   may   be   performed   by   the   user.   All   other   actions  are  prohibited.  

Turn  off  the  brush  before  performing  any  maintenance  operation.  

Remove the protective cover when necessary only when the unit is disconnected.

When  maintenance  is  finished,  make  sure  that  the  protective  cover  is  mounted  correctly  and   attached  with  the  appropriate  screws.  

If these instructions are not observed, the manufacturer will be relieved of all responsibility.

MAINTENANCE, TROUBLESHOOTING, AND CLEANING

The term “maintenance” should not be understood to mean only the periodic check of the unit’s normal functioning, but also the analysis of, and subsequent corrective action for, all those causes that make it inoperative for any reason.

Therefore, it is clear that maintenance involves a large range of mechanical problems, which require the maintenance provider to have a good theoretical and practical knowledge of the unit.

Specifically, the personnel who are responsible for maintenance, cleaning,

replacement of parts, and troubleshooting must set themselves the following goals: a. Limit the deterioration of the parts subject to wear. b. Reduce accidents to a minimum. c. Limit the costs due to accidental malfunctioning. d. Reduce the number and length of service operations. e. Work in cooperation with the line operators to achieve the highest efficiency for the brush.

Regarding the maintenance, cleaning, replacement of parts, and troubleshooting activities performed by the user, it is absolutely necessary that these activities be

entrusted to expert personnel who are qualified and who have been authorized by their employer.

The personnel must receive safety training and must be informed of the residual risks.

If the user does not possess personnel who have been appropriately trained and are

expert or who have been adequately informed, a maintenance contract must be stipulated with qualified companies, such as the supplier of the brush.

13

NON-USE FOR LONG PERIODS OF TIME

 

   

If  the  unit  will  not  be  used  for  a  long  period  of  time,  this  is  an  important  factor  to  be  taken  into   consideration.  In  this  case,  it  will  be  necessary  to  prevent  the  growth  of  algae  and  bacteria  due   to   the   presence   of   stagnant   water.   Also,   the   unit   must   be   protected   from   freezing   temperatures.  

STORAGE

The brush, if placed in storage, must be positioned on its splash guard so that its bristles do not touch the ground, in a well-ventilated space protected from dust. Delivered parts must remain in their packing until the time of their final installation.

All of the brush’s parts that are subject to oxidation at the time of shipping are adequately protected with grease and with protective sprays to prevent oxidation from the elements.

In case of a long period of inactivity, the brush must be stored in accordance with the following precautions regarding the storage place and time:

1. Store the brush in a closed space.

2. Protect the brush from impacts and stress.

3. Protect the brush from moisture and from excessive atmospheric temperature

differences.

4. Prevent the brush from coming into contact with corrosive substances.

5. Check that the packing is not damaged and is completely dry.

PROBLEMS AND SOLUTIONS
