[. . . ] 8-4-16 NOTE If the pipe is bent incorrectly, the indoor unit may unstably be set on the wall. After passing the connecting pipe through the pipe hole, connect the connecting pipe to the auxiliary pipes and wrap the facing tape around them. Push Push CAUTION Bind the auxiliary pipes (two) and connecting cable with facing tape tightly. In case of leftward piping and rear-leftward piping, bind the auxiliary pipes (two) only with facing tape. Indoor unit Auxiliary pipes Connecting cable Installation plate Fig. 8-4-18 Carefully arrange pipes so that any pipe does not stick out of the rear plate of the indoor unit. Carefully connect the auxiliary pipes and connecting pipes to each other and cut off the insulating tape wound on the connecting pipe to avoid double-taping at the joint, moreover, seal the joint with the vinyl tape, etc. Since dewing results in a machine trouble, make sure to insulate both the connecting pipes. (Use polyethylene foam as insulating material. ) When bending a pipe, carefully do it, not to crush it. NOTE Hole should be made at a slight downward slant on the outdoor side. Do not rise the drain hose. Do not form the drain hose into a wavy shape. 8-5. Installation place A place which provides the spaces around the outdoor unit as shown in the left diagram. A place which can bear the weight of the outdoor unit and does not allow an increase in noise level and vibration. Projection margin in flaring : A (Unit : mm) A Tightening torque of flare pipe connections The operating pressure of R410A is higher than that of R22. 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 refrigerant cycle.

Otherwise, the nut may crack depending on the conditions. Use a wrench to secure. Use a torque wrench to tighten. Fig. 8-5-6 CAUTION KEEP IMPORTANT 4 POINTS FOR PIPING WORK (1) Take away dust and moisture (Inside of the connecting pipes. ) (2) Tight connection (between pipes and unit) (3) Evacuate the air in the connecting pipes using VACUUM PUMP. (4) Check gas leak (connected points) - 45 - FILE NO. [. . . ] 2) Remove the 2 screws fixing the base bearing. 3) Remove the bearing from the base bearing. If the housing protrudes from the base bearing, put the housing in position and attach the bearing to the base bearing. 2 2-Screws - 68 - FILE NO.
