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

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.

ROOF CURB
The main purpose of the roof curb is to provide weatherproof passage,
supply and return air down to the building from the ROOFTECH.
In this way, all connections (air, electricity) to the building are not free
above the roof. The curb provides a perfect roofing thermal insulation
and weight distribution between the ROOFTECH and the building.
The roof curb should be used for a downward configuration at supply
and return air. The roof curb guarantees the perfect weathertight
sealing between the building structure and the appliance.
Two versions are available:
Assembled and non-adjustable version

Non-assembled and non-adjustable version
The frame of the curb receiving the unit must be leveled. The unit must slot perfectly into the roof curb.

6 Roof insulation (supplied
by the roofer)
7 Sealant roofskin (supplied by
the roofer)
In order to break a thermal bridge between the roof curb and the unit, a seal (N°2) (50 X 5 mm) is
supplied with the roof curb. This seal must be glued by the installer on the roof curb to avoid metal
to metal contact and reduce eventual vibration transfer.
Once installed and fastened to the roof structure, the outside wall of the curb must be fully integrated in the roof
insulation.
The minimum insulation thickness required is 25 mm and the surface must be protected by a bituminous coating
(or any other equivalent material) to ensure a perfect weatherproof seal.
