CONTROL BOX

1. GENERAL RECOMMENDATIONS

Please read the following safety precautions very carefully before installing the unit.

1.1. 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 qualied 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 qualied 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 qualied personnel only.

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 specic conditions of the location and the current required for any other appliance

connected to 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.

1.2. WARNING

Cutoff power supply before starting to work on the appliance.

The manufacturer declines any responsibility and the warrantly 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 nal 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 modication without advance notice.

1.3. 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 apply to 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 atmosphere 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 heat
sources, such as radiators. The maximum temperature shall never exceed 50°C in the storage place.

Protection clothes Wear boots, safety gloves and glasses or masks for facial protection.

Behaviour in case of leaks or
escapes

Never forget to wear protection clothes and brething apparatus. Isolate the source of the leakage,
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 well ventilated.
In case of a large leakage, ventilate the room immediately. Stop the 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 asphyxiating 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.

2. 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. Conrmation of the type of unit ordered

can be obtained by reading the maker’s plate.
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.

3. WARRANTY

The appliances are delivered fully assembled, factory tested and ready to operate.

Any modication 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:

² Commissioning shall be performed by specialised technicians from technical services approved by

the manufacturer.

² Maintenance shall be performed by technicians trained for this purpose.
² Only Original Equipment spare parts shall be used.
² 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.

HAN

The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work
or constructions. Any foreign weight or stress on the unit structure could lead to a malfunction
or a collapse with dangerous consequences for personnel and property. In such an event, the
warranty shall be null and avoid.

9. INSTALLATION

² The building structure must be capable to carrying the weight of the unit during operation.

² The place of installation must not be subject to ooding.
² The HAN should be installed on a at, clean surface without any obstacles. The surface area must be

sufcient to spread the weight of the unit over the building structure.

² Ensure that the recommended free clearances around the unit are maintained to avoid any risk of

malfunctions.

² Ensure that there are no obstructions around the condenser or the air outlet to avoid any risk of

recycling old air.

² In addition to the service clearances stated on the dimensions sheet, it is imperative to provide a

safe and appropriate access to the unit for repairs and servicing.

² The installer is responsible for providing the weaterproof seal between the building and the HAN. The

installer must be fully versed in the practice of roof mounted equipments and must comply with the
recommendations and rules detailed in the Technical Directives.

² In order to avoid risk of condensation and energy losses, all outdoor ducting and piping must be

insulated.
