(Shall be installed in accordance with national wiring regulations.)

• THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER. R410A refrigerant is apt to be affected by impurities such as water, oxidizing membranes, and oils because the pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. As well as the adoption of this new refrigerant, refrigerating machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not enter the refrigeration cycle of a new-refrigerant air conditioner. To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections on the main unit are different from those for the conventional refrigerant, and different size tools are also required. For connecting pipes, use new and clean piping materials with high- pressure withstand capabilities, designed for R410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping as its pressure withstand may be insufficient and may contain impurities. New refrigerant air conditioner installation CAUTION This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm in all poles. The installation fuse (25A) must be used for the power supply line of this air conditioner. To disconnect the appliance from the main power supply DANGER

• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.
• Do not install in a place which cannot bear the weight of the unit.Personal injury and property damage can result if the unit falls.• Before doing the electrical work, attach an approved plug to the power supply cord.Also, make sure the equipment is properly earthed.• Appliance shall be installed in accordance with national wiring regulations.If you detect any damage, do not install the unit. Contact your Carrier dealer immediately. CAUTION

• Exposure of unit to water or other moisture before installation could result in electric shock. Do not store it in a wet basement or expose to rain or water.• After unpacking the unit, examine it carefully for possible damage.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of the unit or where noise and discharged air might disturb neighbors.• To avoid personal injury, be careful when handling parts with sharp edges.

REQUIREMENT OF REPORT TO THE LOCAL POWER SUPPLIER Please make absolutely sure that the installation of this appliance is reported to the local power supplier before installation. If you experience any problems or if the installation is not accepted by the supplier, the service agency will take adequate countermeasures.Remark per EMC Directive 89/336/EEC To prevent flicker impressions during the start of the compressor (technical process), following installation conditions does apply. 1. The power connection for the air conditioner has to be done at the main power distribution. This distribution has to be of an impedance. Normally, the required impedance is reached at a 32A fusing point. Air conditioner fuse has to be 16A max.!2. No other equipment should be connected to this power line. 3. For detailed installation acceptance, please contact your power supplier whether its restriction does apply for products like washing machines, air conditioners or electric ovens.4.

1 Installation plateEN 7 Refrigerant Piping Connection Evacuating After the piping has been connected to the indoor unit, you can perform the air purge together at once. AIR PURGE Evacuate the air in the connecting pipes and in the indoor unit using a vacuum pump. Do not use the refrigerant in the outdoor unit. For details, see the manual of the vacuum pump. Pressure gaugeManifold valve–101 kPa(–76 cmHg)Handle LoConnecting pipe Compound pressure gaugeVacuum pump Handle Hi(Keep full closed)Charge hose(For R410A only)Charge hose(For R410A only)Vacuum pump adapter forcounter-flow prevention(For R410A only)Packed valve at gas sideService port (Valve core (Setting pin))Packed valve at liquid side Using a vacuum pump Be sure to use a vacuum pump with counter-flow prevention function so that inside oil of the pump does not flow backward into pipes of the air conditioner when the pump stops. (If oil inside of the vacuum pump enters the air conditioner, which use R410A, refrigeration cycle trouble may result.) 1.Connect the charge hose from the manifold valve to the service port of the packed valve at gas side. 2.Connect the charge hose to the port of the vacuum pump. 3.Open fully the low pressure side handle of the gauge manifold valve. 4.Operate the vacuum pump to start evacuating. Perform evacuating for about 15 minutes if the piping length is 20 meters. (15 minutes for 20 meters) (assuming a pump capacity of 27 liters per minute) Then confirm that the compound pressure gauge reading is –101 kPa (–76 cmHg). 5.Close the low pressure side valve handle of the gauge manifold valve. 6.Open fully the valve stem of the packed valves (both gas and liquid sides). 7.Remove the charging hose from the service port. 8.Securely tighten the caps on the packed valves. CAUTION

• KEEP IMPORTANT 4 POINTS FOR PIPING WORK. (1) Take away dust and moisture (inside of the connecting pipes). (2) Tighten the connections (between pipes and unit). (3) Evacuate the air in the connecting pipes using a VACUUM PUMP. (4) Check gas leak (connected points).

• Tightening torque of flare pipe connections The operating pressure of R410A is higher than that of R22 (approx. 1.6 times). It is therefore necessary to firmly tighten the flare pipe connecting sections (which connect the indoor and outdoor units) up to the specified tightening torque. Incorrect connections may cause not only a gas leakage, but also damage to the refrigeration cycle.
