GENERAL RECOMMENDATIONS
Please read the following safety precautions very carefully before installing the unit.
SAFETY DIRECTIONS
Follow the safety rules in forces when you are working on your appliance.
The installation, commissioning and maintenance of these units should be performed by qualified personnel having
a good knowledge of standards and local regulations, as well as experience of this type of equipment.
Given the requirements of pressurising the system and the high current draws involved, this roof-
mounted air conditioning should only be installed by qualified personnel.
The unit should be handled using lifting and handling equipment appropriate to the unit's size and weight.
Given the high refrigerant temperatures present at certain points in the cooling circuit, access to
the area protected by the panels is strictly reserved for qualified personnel only. These panels are
easily opened with a special tool. This tool should be kept by the installers or by the maintenance
company.
Any wiring produced on site must comply with the corresponding national electrical regulations.
Make sure that the power supply and its frequency are adapted to the required electric current of operation, taking
into account specific conditions of the location and the current required for any other appliance connected with
the same circuit.
The unit must be EARTHED to avoid any risks caused by insulation defects.
It is forbidden to start any work on the electrical components if water or high humidity is present on the installation
site.
WARNING
Cutoff power supply before starting to work on the appliance.
When making the hydraulic connections, ensure that no impurities are introduced into the pipe work.
The manufacturer declines any responsibility and the warranty becomes void if these instructions
are not respected.
If you meet a problem, please call the Technical Department of your area.
If possible, assemble the compulsory or optional accessories before placing the appliance on its final location. (see
instructions provided with each accessory).
In order to become fully familiar with the appliance, we suggest to read also our Technical Instructions.
-The informations contained in these Instructions are subject to modification without advance notice.

EQUIPMENT SAFETY DATA
Safety Data R410A
Toxicity Low
In contact with skin Skin contact with the rapidly evaporating liquid may cause tissue chilblains. In case of
skin contact with the liquid, warm the frozen tissue with water and call a doctor. Remove
contaminated clothing and footwear. Wash the clothing prior to re-use.
In contact with eyes Vapours have no effect. Liquid splashes or sprays may cause freeze burns. In these
cases rinse your eyes with running water or with a solution for eye lavages for at least
10 minutes. Immediately contact a doctor.
Ingestion In this case, burns may result. Do not attempt to make the patient vomit. If the patient
is conscious, rinse the mouth with water. Call a doctor immediately.
Inhalation In case of inhalation, move the patient to an area with fresh air and provide oxygen if
necessary. Perform artificial respiration if the patient has stopped breathing or lacks air.
In case of cardiac arrest, perform external cardiac massage. Call a doctor immediately.
Further Medical Advice Exposure to high concentrations can be dangerous for individuals with cardiac problems,
as the presence of catecholamines such as adrenalin in the bloodstream may lead to
increased arrhythmia and possible cardiac arrest.
Occupational exposure
limits
R410A: Recommended limits: 1,000 ppm v/v 8 hours TWA.
Stability Stable product
Conditions to avoid Increased pressure due to high temperatures may cause the container to explode. Keep
out of the sun and do not expose to a temperature >50°C.
Hazardous reactions Possibility of dangerous reactions in case of fire due to the presence of F and/or CI
radicals
General precautions Avoid the inhalation of high concentrations of vapours. The concentration in the atmos-
phere shall be kept at the minimum value and anyway below the occupational limits.
Since vapours are heavier than air and they tend to stagnate and to build up in closed
areas, any opening for ventilation shall be made at the lowest level.
Breathing protection In case of doubt about the actual concentration, wear breathing apparatus. It should
be self-contained and approved by the bodies for safety protection.
Storage Preservation Refrigerant containers shall be stored in a cool place, away from fire risk, direct sunlight and all
heatsources,suchasradiators.Themaximumtemperatureshallneverexceed50°Cinthestorage
place.
Protection clothes Wear boots, safety gloves and glasses or masks for facial protection.
Behaviour in case of
leaks or escapes
Never forget towearprotectionclothesandbrethingapparatus.Isolatethesourceoftheleakage,
provided that this operation may be performed in safety conditions. Any small quantity of
refrigerant which may have escaped in its liquid state may evaporate provided that the room is
wellventilated.Incase of a largeleakage, ventilate theroom immediately. Stopthe leakage with
sand, earth or any suitable absorbing material. Prevent the liquid refrigerant from flowing into
drains, sewers, foundations or absorbing wells since its vapours may create an asphyxia-
ting atmosphere.
Disposal The best procedure involves recovery and recycle. If this is not possible, the refrigerant shall be
given to a plant which is well equipped to destroy and neutralise any acid and toxic by-product
which may derive from its disposal.
Combustibility features R410A: Non-inflammable at ambient temperatures and atmospheric pressures.
Containers If they are exposed to the fire, they shall be constantly cooled down by water sprays.
Containers may explode if they are overheated.
Behaviour in case of
fire
In case of fire wear protection clothes and self-contained breathing apparatus.

INSPECTION AND STORAGE
At the time of receiving the equipment carefully cross check all the elements against the shipping documents in
order to ensure that all the crates and boxes have been received. Confirmation of the type of unit ordered can be
obtained by reading the maker’s plate (capacity, type and air blowing configuration).
Inspect the units for any visible or hidden damage.
In the event of shipping damage, write precise details of the damage on the shipper’s delivery note
and send immediately a registered letter to the shipper within 48 hours, clearly stating the damage
caused. Forward a copy of this letter to the manufacturer or their representative.
Never store or transport the unit upside down. Protect unit at the job side from domages made by others. When
unit is stored on the ground, avoid mud store unit leveled.

WARRANTY
The appliances are delivered fully assembled, factory tested and ready to operate.
Any modification to the units without the manufacturer’s prior approval, shall automatically render the warranty
null and void.
The following conditions must be respected in order to maintain the validity of the warranty:
Commissioning shall be performed by specialised technicians from technical services approved by

the manufacturer.
Maintenance shall be performed by technicians trained for this purpose.

Only Original Equipment spare parts shall be used.
All the operations listed in the present manual shall be performed within the prescribed schedule.
THE WARRANTY SHALL BE NULL AND VOID IN THE EVENT
OF NON-COMPLIANCE WITH ANY OF THE ABOVE CONDITIONS.
PRESENTATION
The machine has been designed for an outdoor mounted application, ensuring perfectly weatherproof circulation
of the air within the compartments.
Packaged ROOFTECH units are designed to safeguard to environment and reduce building energy consumption
by the use of R410A as a refrigerant and double skin 50 mm panels for greater thermal insulation.
All the units are factory charged and tested, and ready to install to guarantee quick and efficient commissioning.
A modular design enables the system to be adapted perfectly to the client’s configuration. The present manual
defines the characteristics of the base module.
INSTRUCTIONS FOR FILLING IN THE "1st START-UP FORM"
(SEE APPENDIX)
It is the responsibility of the OWNER to make sure that the "1st Start-up Form" is fully filled in by the authorized
Service Centre and sent by registered mail - notified in advance by fax - to the After-Sales Service of the constructor
within 8 days of the initial start-up.
Failure to receive the form on the part of the constructor will render the guarantee null and void.
The OWNER must then keep the logbook for at least the duration of the guarantee.
The constructor reserves the right to request a copy of the "Machine Logbook" at any moment whatsoever. Failure
to fill in the logbook may render the guarantee null and void.
