Drain kit (Option) For drain-up kit installation. Refer the installation manual supplied with the drain-up kit. Fig. If the outdoor units are to be mounted on a wall, make sure that the platform supporting is sufficiently strong. The platform should be designed and manufactured to maintain its strength over a long period of time, and sufficient consideration should be given to ensuring that the outdoor unit will not fall. Use copper pipe with 0. 8 mm or more thickness. Flare nut and flare works are also different from those of the conventional refrigerant. Take out the flare nut attached to the main unit of the air conditioner, and use it. · Flaring size : A (Unit : mm) A Outer diam. of copper pipe R410A 6. 35 9. 52 12. 7 9. 1 13. 2 16. 6 +0 - 0. 4 R22 9. 0 13. 0 16. 2 * In the case of flaring for R410A with the conventional flare tool, pull out it approx. 0. 5 mm more than that for R22 to adjust to the specified flare size. Connect the charge hose to the port of vacuum pump. Open fully the low pressure side handle of the gauge manifold valve. Operate the vacuum pump to start for evacuating. Perform evacuating for about 35 minutes if the piping length is total 70 meters. (25 minutes for total 50 meters) (assuming a pump capacity of 27 liters per minute. ) Then confirm that the compound pressure gauge reading is ­101 kPa ( ­76 cmHg). Close the low pressure side valve handle of gauge manifold. Open fully the valve stem of the packed valves (both sides of Gas and Liquid). Remove the charging hose from the service port. Securely tighten the caps on the packed valves. [Hexagonal wrench is required. ] Fig. 9-7-1 Compound pressure gauge Pressure gauge ­101kPa (­76cmHg) Handle Lo Charge hose Manifold valve Handle Hi (Keep full closed) Charge hose Vacuum pump adapter for counter-flow prevention Packed valve at liquid side Vacuum pump Service port (Valve core (Setting pin)) Packed valve at gas side Fig. Electrical Work For the air conditioner that has no power cord.
