1. GENERAL CONDITIONS.
Before installing and starting up the Machine, read all the technical and
safety documentation included in this manual carefully. It is important to pay
particular attention to the information included here in order to become
acquainted with handing and operating conditions of the Unit. All
information is focused on bolstering User Safety and avoiding any possible
breakdown arising from the incorrect use of the Unit.
Careful reading of this Technical Manual will give you a better knowledge of the system and
procedures. Following the instructions and recommendations included here will reduce the
potential risk of accident during installation, use or maintenance of the Machine, and will make
it possible to have an incident-free operation for a longer period of time, better performance
and the possibility to detect and solve problems in a swift and simple manner.
Keep this Technical Manual. You will be able to make consultations in the future, with access to
useful information at all times. In the event of misplacing the manual, please request a copy
from Celtipol.
The design of the Machine does not allow for it to be used in potentially
explosive environments. Nor should the pressure and temperature limits
stipulated in the technical specifications in this manual be surpassed.

2. SAFETY CONDITIONS
The first consideration to take into account is that during the design and project stage of the
CN-4 machine, the regulations in force regarding machine Safety and Prevention of Risk in the
Work Place have been scrupulously respected. Therefore, we can firmly state that the machine
is intrinsically safe.
Nevertheless, in common with any machine or tool, incorrect use of the same may cause more
or less hazardous situations. These recommendations have been drafted to avoid such
situations to ensure safe use and handling of the system.
Leading on from the above, clearly, all personnel that have anything to do with the spraying
and handling operations of the machine must have an in-depth knowledge of these
recommendations as well as all other recommendations that may be provided by the
manufacturers of chemical products.
Throughout these operations, the intention is to provide a non-exhaustive list of the possible
risks that may arise from spraying operations. For this reason, and depending on each particular
application, it must be the user of the system who should carefully study the risks arising from
the same, in line with the Regulation in force on the Prevention of Risks in the Work Place.
Another aspect for consideration is the prevention of possible risks arising from the use of
different chemical products, some of which may be hazardous if used incorrectly. Special
attention should be paid to any fumes issued during use of polyurethane foam and polyurea
systems since isocyanate compounds are used in spraying operations.
In short, to ensure that the handling and use of the spraying equipment is as safe as possible,
the user must strictly follow the following aspects indicated in this manual.

3. APPLICATION SAFETY.
• It is advisable for personnel with a history of respiratory complaints to avoid exposure to all
isocyanates.
• Chemical products must be handled safely in accordance with manufacturer's
recommendations. The manufacturer should provide information on the toxicity of the
products used as well as actions to take in the event of accident (wounds, irritation, etc.).
• It should be taken into account that solvents that may be used in cleaning operations may
also entail additional risk during handling.
• Do not apply until adequate ventilation is ensured, either naturally or forced, if required.
Suppliers of chemical products must be applied to in order to determine the values at which the
concentrations of fumes may be hazardous.
• The appropriate procedures and systems must be applied to detect hazardous concentrations
of fumes.
• In the event of not being able to ensure appropriate ventilation, both the personnel applying
substances and those working in the area influenced by fumes must, without fail, use certified
breathing apparatus.
At all times, users must use the appropriate personal protection equipment (gloves, breathing
masks, goggles, protective clothing, etc.).
• Users must be completely familiar with the chemical products and with the use of the
equipment.
In order to prevent any possible bodily harm caused by incorrect handling of raw
materials and solvents used in the process, please read carefully the safety
information provided by the supplier.
Treat waste according to the regulations in force.
Electrical maintenance of the machine must only be conducted by a qualified
electrician.
In order to avoid damage caused by the impact of pressurized fluids, do not open any
connection or carry out any maintenance work on components under pressure until
the pressure has been completely eliminated.
Use appropriate protection for operating, maintenance work or whenever present in
the working area of the Machine. This includes but is not limited to the use of a face
mask, goggles, gloves, footwear and safety clothing.
Certain components of the Machine reach temperatures that can cause burns. Do not
handle or touch the hot parts in the Machine until they have cooled down.
In order to prevent any serious harm due to crushing or amputations, do not work
with the Machine without safety protection from duly installed moving parts. Make
sure that all safety protection is correctly fitted when completing repairs or
maintenance work.

4. SAFE HANDLING OF CHEMICAL PRODUCTS.
Products such as polyisocianates, organic solvents and diamines should be stored in a place
exclusively for and adapted to such a purpose, with restricted access. Maximum temperatures
must be strictly adhered to, both in the application and in storage of chemical products, at all
times following the manufacturer's recommendations.
• Also, chemical products are to be stored at all times in suitable containers, following the
manufacturer’s recommendations.
• Containers must not be opened until immediately before being used in order to avoid
contamination by damp. Any leftover product after being applied should be put back into the
original container and be stored in a dry, ventilated place.
• During cleaning tasks of spilt components, it will be essential to use eye protection, gloves
and wearing breathing apparatus. Spilt isocyanate can be collected with any absorbent inert
product, such as sawdust. In any case, it is important to avoid skin contact. The absorbent
product is to be immediately collected and dumped into an open container through the upper
part.
• Throughout the entire operation explained above, the area must be correctly ventilated.
Safety personnel equipment:
Celtipol recommends the following personnel safety equipment for operations with foaming
(see table):
•• Protective mask for airways.
•• Goggles to protect the eyes.
•• Headset to protect against noise.
•• Gloves to protect hands.
•• Protective clothing for the body.
