It must not be used at temperatures lower than 0°C.• If the unit is installed in areas where heavy snowfalls mayoccur, it is necessary to raise its level at least 200 mmabove the usual snow level or alternatively use the outdoorunit bracket kit.General informationUnit installationR-410A systems operate at higher pressures than standardR-22 systems. Do not use R-22 service equipment orcomponents on R-410A equipment.Read this instruction manual thoroughly before starting theinstallation.• This unit complies with low-voltage (EEC/73/23) and electro-magnetic compatibility (EEC/89/336) directives.• Check that the impedance of the mains power supply is inconformance with the unit power input indicated in theelectric data table III, on page 11 (EN 61000-3-11).• The installation must be carried out by a qualified installer.• Follow all current national safety code requirements. Inparticular ensure that a properly sized and connected groundwire is in place.• Check that voltage and frequency of the mains power supply arethose required; the available power must be adequate to operateany other possible appliances connected to the same line.Also ensure that national safety code requirements have beenfollowed for the mains supply circuit.• The mains supply must be connected to the outdoor unit.• Connect indoor and outdoor units with field-supplied copperpipes by means of flare connections. Use insulated seamlessrefrigeration grade pipe only, (Cu DHP type according toISO1337), degreased and deoxidized, suitable for operatingpressures of at least 4200 kPa and for burst pressure of atleast 20700 kPa. Under no circumstances must sanitary typecopper pipe be used.• After installation thoroughly test the system operation and explainall system functions to the owner.• Leave this manual with the owner for consultation during futureperiodic maintenance.• Use this unit only for factory approved applications: the unit issuitable for outdoor installation.• This installation manual describes the installation procedures ofthe outdoor unit of a residential split system consisting of unitsmanufactured by Carrier.
