General Information

Unit installation

Read this instruction manual thoroughly before starting

installation.

• This unit complies with the low-voltage (2006/95/EC) and
electromagnetic compatibility (2004/108/EC) directives.
If CARRIER controls are NOT used by the installer it is his own
responsibility to check compliance with the following directives:
- Low-voltage (2006/95/EC)
- Electromagnetic compatibility (2004/108/EC)
• The installation must be carried out by a qualified installer.
• The unit should be installed according to the national standards on
plants.
• Check that the voltage and frequency of the mains power supply are
as required for the unit to be installed; the available power source
must be adeguate to operate all other appliances connected to the
same line.
• Also ensure that national safety code requirements have been
followed for the main supply circuit.
• Where necessary, use 16 mm I.D. PVC pipe of appropriate length (not
supplied) and with the correct thermal insulation for the condensate
drain extension.
• After installation thoroughly test system operation and explain all
system functions to the owner.
• Use this unit only for factory approved applications: the unit cannot
be used in laundry or steam pressing premises.
WARNING: Disconnect the mains power supply switch before
servicing the system or handling any internal parts of the unit.

Warnings: avoid

... any obstruction of the unit air intake or supply grilles (See fig. 3).
... exposure to oil vapours (See fig. 4).
... installation in areas with high frequency waves (See fig. 5).
... ascending sections of condensate drain piping.
These may only be used near the unit with a maximum height
difference of 200 mm from the top of the unit (See fig. 6).
... horizontal sections or curves of condensate drain piping with less
than 2% slope (See fig. 7).
... exposure to direct sunshine, when the unit is operating in the cooling
mode; always use shutters or shades.
... positions too close to heating sources which may damage the unit
Installation
See fig. 15.
• Install the unit as centrally as possible in the room, the air flow
direction can be controlled by manually regulating the louvres
position, according to the operating mode (cooling or heating): this
will ensure optimum distribution of the air in the room.
• During cooling mode operation the best position for the deflecting
louvres is one which allows air diffusion close to the ceiling (Coanda
effect). In heating mode, the louvres should be positioned so that the
air is directed towards the floor, in order to prevent layers of hot air
forming in the upper part of the room.
• In order to allow easy and rapid installation and maintenance, make
sure that in the selected position it is possible to remove the ceiling

• The manufacturer declines any liability for damage resulting from
modifications or errors in the electrical or water connections.
• Failure to observe the installation instructions, or use of the unit under
conditions other than those indicated in Table "Operating limits" of the
unit installation manual, will immediately invalidate the unit warranty.
• Failure to observe electric safety codes may cause a fire hazard in the
event of short circuits.
• Inspect equipment for damage during transport. In case of damage
file an immediate claim with the shipping company.
• Do not install or use damaged units.
• In case of malfunction turn the unit off, disconnect the mains power
supply and contact a qualified service engineer.
• Maintenance must only be carried out by qualified personnel.
• All of the manufacturing and packaging materials used for this
appliance are biodegradable and recyclable.
• Dispose of the packaging material in accordance with local
requiremements.

Choosing the installation site

Positions to avoid:
• Exposure to direct sunlight.
• Areas close to heat sources.
• On damp walls or in positions that may be exposed to water hazard.
• Where curtains or furniture may obstruct free air circulation.
Recommendations:
• Choose an area free from obstructions which may cause uneven air
distribution and/or return.
• Consider using an area where installation is easy.
• Choose a position that allows for the clearances required.
• Look for a position in the room which ensures the best possible air
distribution.
• Install unit in a position where condensate can easily be piped to an
appropriate drain.
(See fig. 8).
... connecting condensate piping to sewage system drain without
appropriate trap.
Trap height must be calculated according to the unit discharge head
in order to allow sufficient and continuous water evacuation (See fig.
9-10).
... only partial insulation of the piping.
Non-level installation which will cause condensate dripping
(See fig. 11).
... flattening pipes or condensate pipes (See fig. 12-13).
...slack on electrical connections (See fig. 14).
panels or, if the ceiling is constructed of masonry, that access to the
unit is guaranteed.
ATTENTION:
Only restrict the air outlets as indicated in the drawing fig.15
For units equipped with electric heaters the use of the "AIR SUPPLY
OBSTRUCTION" kit is NOT allowed.

Prior to installation

It is advisable to place the unit as close as possible to the installation site
before removing it from the packaging.
The grille panel and the control are separately packed for maximum
protection (See fig. 16).
