[. . . ] As the flaring sizes of R410A differ from those of refrigerant R22, the flare tools newly manufactured for R410A are recommended. However, the conventional tools can be used by adjusting projection margin of the copper pipe. B 9-3-7. Installation NOTE : For installation, at least 3 dimensions should be kept free from obstacles (walls). 3. The length and height difference of the connecting pipes between the indoor and outdoor units must be within the ranges indicated below. · Total piping length : Three room (A + B + C) Multi, Non. Additional refrigerant : 40 m or less 600mm or more B C mo 100 re mm fro m wor all re r mo m o wall 50m from · Minimum piping length : A or B or C = 2 m or more · Maximum indoor piping length : A or B or C = 20 m or less · Maximum piping height difference : A or B or C = 10 m or less 9-3-5.

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. Insulate the unused cords (conductors) with strip the sheath of connecting cable with PVC tape. Process them so that they do not touch any electrical or metal parts. For inter-unit wiring, do not use a cut wire jointed to another on the way. Use wires long enough to cover the entire length.

Otherwise, the nut may crack depending on the conditions. of copper pipe Ø6, 35 mm Ø9, 52 mm Ø12, 7 mm Tightening torque AIR PURGE Evacuate the air in the connecting pipes and in the indoor unit using vacuum pump. Do not use the refrigerant in the outdoor unit. For details, see the manual of vacuum pump.

[. . . ] 9) Wind the attached color tape round the both terminals of the protective tube when colored protective tube is used. NOTES : 1) Store the joint part of the sensor and the connector in the electric parts box. 2) Never joint them near the thermal sensor part. Otherwise it would cause insulation inferiority because of dew drops. [. . . ]
