General information
Unit installation
Read this instruction manual thoroughly before starting
installation.
• This unit complies with the low-voltage (EEC/73/23) and
electromagnetic compatibility (EEC/ 89/336) directives.
• Follow all current national safety code requirements.
In particular ensure that a properly sized and connected ground
wire is in place.
• 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 adequate 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.
• Connect the main supply to the outdoor unit.
• Connect indoor and outdoor units with field-supplied copper pipes
with flare connections.
Use insulated seamless refrigeration grade pipe only,
(Cu DHP type according to ISO 1337), degreased and deoxidised,
suitable for operating pressures of at least 3000 kPa.
Under no circumstances must sanitary type copper pipe be used.
• Where necessary, use field-supplied 25 mm I.D. PVC pipe of
appropriate length 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.
• Do not open the remote control to avoid possible damage. In case
of malfunctioning contact a qualified service engineer.
• This installation manual describes the installation procedures of
the indoor unit of a residential split system consisting of two
Carrier manufactured units.
Do not connect this unit to any other manufacturer's outdoor unit.
The manufacturer declines any liability for system malfunction
resulting from unauthorised system combinations.
• The manufacturer declines any liability for damage resulting
from modifications or errors in the electrical or refrigerant
connections.
Failure to observe the installation instructions, or use of the
unit under conditions other than those indicated in table
“Operating limits” of the outdoor 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.
• This equipment contains ozone depleting substances.
Maintenance of the refrigerant circuit 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.
• This equipment contains refrigerant that must be disposed of
correctly.
When disposing of the unit at the end of its operational life,
take the unit to an authorised waste disposal centre, or to the
original equipment dealer, for correct disposal.
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.

Avoid...
... any obstruction of the unit air intake or supply grilles. ... 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.
ENGLISH
... exposure to oil vapours.
... installation in areas with high frequency waves. ... only partial insulation of the piping.
MAX 200 mm
... 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.
Non-level installation which will cause condensate dripping.
... 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.
... horizontal sections or curves of condensate drain piping with less
than 2% slope.
... flattening or kinking the refrigerant pipes or condensate pipes.
... excessive height difference between outdoor and indoor units
(see installation manual of outdoor unit).
