General information

Unit installation

Read this instruction manual thoroughly before starting the installation. This unit complies with low-voltage (EEC/73/23) and electromagnetic compatibility (EEC/89/336) directives. The installation must be carried out by a qualified installer. Follow all current national safety code requirements. In particular ensure that a properly sized and connected ground wire is in place. Check that voltage and frequency of the mains power supply are those required for the unit to be installed; the available power must be adequate to operate any other possible appliances connected to the same line. Also ensure that national safety code requirements have been followed for the mains 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 ISO 1337), degreased and deoxidized, suitable for operating pressures of at least 4200 kPa. Under no circumstances must sanitary type copper pipe be used. Use field-supplied 16 mm I.D. PVC pipe (not supplied) of appropriate length and with the correct thermal insulation for the condensate drain. After installation thoroughly test the system operation and explain all system functions to the owner. Leave this manual with the owner for consultation during future periodic maintenance. Use this unit only for factory approved applications: the unit cannot be used in laundry or steam pressing premises. IMPORTANT: During the unit installation make first refrigerant connections and then electrical connections. When disassembling first disconnect electrical cables, then 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 controller 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 units manufactured by Carrier. Consult factory or a qualified system engineer prior to connecting this unit to any other manufacturer's outdoor unit. Coupling units which have different control systems, may cause irreversible damage and void the warranty protection. The manufacturer declines any liability for system malfunction resulting from unapproved coupling. Operating conditions outside the operating range (Connections), will cause safety device tripping or damage to unit components. 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 IV (operating limits) of the outdoor unit installation manual, will immediately void the unit warranty. Failure to observe electric safety codes may cause a fire hazard in case of short circuits. Inspect equipment for damage due to improper transportation or handling: file an immediate claim with the shipping company. Do not install or use damaged units. In case of any malfunctioning turn the unit off, disconnect the mains power supply and contact a qualified service engineer. This equipment contains R-410A refrigerant, a substance that is not depleting the ozone layer. All of the manufacturing and packaging materials used for your new appliance are compatible with the environment and can be recycled. Dispose of the packaging material in accordance with local requirements. This equipment contains refrigerant that must be disposed of in the proper manner. When disposing of the unit after its operational life, remove it carefully. The unit must then be delivered to an appropriate disposal centre or to the original equipment dealer, for proper environmentally friendly disposal.

Choosing the installation site
Positions to avoid: Exposed to direct sun. Too close to heat sources. On humid walls or positions with water hazard, e.g. laundry premises. Where curtains or furniture may obstruct free air circulation.
Recommendations: Choose an area free from obstructions which may cause irregular air distribution and/or return. Check that the wall surface is flat enough to allow easy and safe installation. The wall structure should be strong enough to carry the unit weight and avoid deformation, rupture or vibration during operation. Consider using an area where installation is easy. Choose a position that allows for the clearances required (see drawing). Look for a position in the room which assures the best possible air distribution. Install the unit in a position where condensate can easily be piped to an appropriate drain.

Conduits can be of flexible polyester (with spiral core) or corrugated aluminium, externally covered with anti-condensate material (fibre glass from 12 to 25 mm thickness). To complete the installation, all non-insulated ducts must be covered with anti-condensate insulation (ex. expanded neoprene, 6 mm thickness). Not observing of these instructions may cause condensate dripping; the manufacturer will not be held responsible for any damage caused.
The supplementary fan motor for outside air intake has to be supplied separately and controlled by a bipolar ON-OFF switch with safety fuses (field-installed). To adjust the fan motor air flow to the required values it is advisable to install a speed controller. Fresh air flow must be less than 10% of the total air flow, to avoid operating problems. For fresh air ventilation rates higher than 10%, a primary air treatment system with separate deflectors is recommended. Install an air inlet grille with filter inspection port to prevent dust and dirt from entering and fouling the indoor unit heat exchanger. Filter installation also makes the installation of a duct closing damper during shutdown periods unnecessary.
