Install the outdoor unit without anything blocking the air discharging. When the outdoor unit is installed in a place exposed always to a strong wind like a coast or on a high story of a building, secure the normal fan operation using a duct or a wind shield. Specially in windy area, install the unit to prevent the admission of wind. · A place where high-frequency waves are likely to be generated as from audio equipment, welders, and medical equipment. 12. 7 15. 88 <Tightening Connection> Align the centers of the connecting pipes and tighten the flare nut as far as possible with your fingers. Then tighten the nut with a spanner and torque wrench as shown in the figure. CAUTION · Do not apply excess torque. Otherwise, the nut may crack depending on the conditions.

AIR PURGE Evacuate the air in the connecting pipes and in the indoor unit using vacuum pump. <Use 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. Connect the charge hose from the manifold valve to the service port of the gas side packed valve. 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). Open fully the valve stem of the packed valves (both side of Gas and Liquid). Securely tighten the caps on the packed valves.
