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.
• Installation must be carried out by qualified personnel.
• 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.
• Connection of the system to the mains power supply is to be
carried out in compliance with the wiring diagram shown in
the installation instructions of the external section.
• Connect indoor and outdoor units with field-supplied copper pipes
by means of flare connections. Use insulated seamless
refrigeration grade pipe only, (Cu DHP type according to ISO1337),
degreased and deoxidized, suitable for operating pressures of at
least 4200 kPa and for burst pressure of at least 20700 kPa.
Under no circumstances must sanitary type copper pipe be used.
• Where necessary, use field-supplied 25 mm I.D. PVC pipe (not
supplied) 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.
IMPORTANT:
During installation, make first the refrigerant connections and
then the electrical connections.
If the unit is uninstalled, first disconnect the electrical cables,
and then the refrigerant connections.
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.
General information

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.
