[. . . ] When doing installation work on level ground, it is usual to wiring and piping connections to the indoor units. However if outdoor work is difficult it is possible instead to make changes to the procedure. For example by making adjustments to the wiring and piping length on the inside (rather than the outside). CAUTION KEEP IMPORTANT 4 POINTS FOR PIPING WORK 1. Tight connection (between pipes and unit) 3. Evacuate the air in the connecting pipes using VACUUM PUMP.

Piping connections to the outdoor unit should be arranged in the sequence A, B, C, starting from the bottom. (For each piping connection, the gas pipe is on the bottom and the liquid pipe is on the top. ) 2. When multiple indoor units are to be connected to the outdoor unit, make the ends of the pipes and wires from each indoor unit to ensure that they will be connected to the outdoor unit correctly. (Problems caused by indoor units being connected to the outdoor unit incorrectly are very common in multiple-unit installations. ) Flaring 1. Cut the pipe with a pipe cutter. 90° Obliquity Roughness Warp flaring for R410A * In the case offlare tool, pull out itwith the 0, 5 conventional approx. mm more than that for R22 to adjust to the specified flare size. The copper pipe gauge is useful for adjusting projection margin size. A How to remove the valve cover 1. 9-3-8 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. 9-3-8. Evacuating After the piping has been connected to all indoor unit(s), you can perform the air purge together at once. Compound pressure gauge -101kPa (-76cmHg) Pressure gauge How to wiring connection 1. Connect the connecting cable to the terminal as identified with their respective matched numbers on the terminal block of indoor and outdoor unit. When connecting the connecting cable to the outdoor unit terminal, prevent water coming in the outdoor unit.
