R-410A – QUICK REFERENCE GUIDE

•R-410A refrigerant operates at 50%-70% higher pressures than R-22. Be sure that servicing equipment and replacement components are designed to operate with R-410A.

•R-410A refrigerant cylinders are pink.

•R-410A refrigerant cylinders have a dip tube which allows liquid to flow out of cylinder in an upright position.

•In case of maintenance, R-410A systems should be charged with refrigerant in liquid phase. Use a commercial type metering device in the manifold hose in order to vaporize the liquid refrigerant before it enters in the unit.

•The R-410A, as for other HFC, is only compatible with oils chosen by the compressor manufacturer. For this reason, for the type of oil to be used, always refer to the plate on the compressor and the unit.

•A vacuum pump is not enough to remove moisture from oil.

•POE oils absorb moisture rapidly. Do not expose oil to atmosphere.

•Never open system to atmosphere while it is under vacuum.

•When the system must be opened for service, break vacuum with dry nitrogen and replace filter driers.

•Do not vent R-410A into the atmosphere.

•Use only Carrier matching indoor units (Table I).

General information

Unit installation

Read this instruction manual thoroughly before starting the installation.

R-410A systems operate at higher pressures than standard R-22 systems. Do not use R-22 service equipment or components on R-410A equipment.

• This unit complies with low-voltage (EEC/73/23) and electromagnetic compatibility (EEC/89/336) directives.

• Check that the impedance of the mains power supply is in conformance with the unit power input indicated in the electric data table V (EN 61000-3-11).

• 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; 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.

• The mains supply must be connected to the outdoor unit.

• 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.

• 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 is suitable for outdoor installation.

• This installation manual describes the installation procedures of the outdoor 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 indoor 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.

IMPORTANT: During the unit installation make first refrigerant connections and then electrical connections. If unit is uninstalled 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. All mains supply circuits must be disconnected.

• Carefully recover refrigerant within this unit before final disposal or when servicing. Never vent refrigerant to atmosphere. Use approved recovery equipment for R-410A refrigerant. Do not use R-22 equipment.

Choosing the installation site

Positions to avoid:

• Exposed to direct sun.

• Too close to sources of heat radiation, vapour or flammable gas.

• Particularly dusty areas.

Recommendations:

• Choose a position protected from opposing winds.

• Choose a position sheltered from direct sun.

• Choose an area where air outlet and unit noise will not bother

your neighbours.

• Choose a position that allows for the clearances required.

• Floor structure should be adequately strong to support unit weight

and minimize vibration transmission.

• Consider a position which will not obstruct passageways or doors.

• Fix the unit with locally purchased bolts buried in the block to prevent overturning due to strong gusts of wind.

• For heat pump models, unit must be adequately raised above floor surface.

• 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 III “Operating limits”, 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 a proper manner. When disposing of the unit after its operational life, remove it carefully. The unit must then be delivered to an appropriate disposal center or to the original equipment dealer.

햶 Vinyl pipe

• To empty the condensate water to a drain while operating in heating mode, insert the drain fitting into the hole underneath on the centre of the base and use a vinyl pipe with a 16 mm inside diameter. It must not be used at temperatures below 0°C (not available for low temperature versions).

Snow

• If the unit is installed in areas where heavy snowfalls may occur, it is necessary to raise its level at least 200 mm above the usual snow level or alternatively to use the outdoor unit bracket kit.
