After passing the connecting pipe through the pipe hole, connect the connecting pipe to auxiliary pipes and wrap the facing tape around them. Fig. 8-4-12 <In case of downward piping> · After scribing the slit of the front panel and slit in the lower part of the rear panel by a knife or a marking-off pin, cut them by a pair of nippers or the like. 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 Slit (front panel) Slit (rear panel) Fig. 8-4-13 <Left-hand connection with piping> Bend the connecting pipe so that it is laid within 43 mm above the wall surface. If the connecting pipe is laid exceeding 43 mm above the wall surface, the indoor unit may unstably be set on the wall. When bending the connecting pipe, make sure to use spring bender so as not to crush the pipe. Bend the connection pipe within a radius of 30 mm. Installation plate · Carefully arrange pipes so that any pipe does not stick out of the rear plate of the indoor unit. · A place which does not block a passage. · When the outdoor unit is to be installed in an elevated position, be sure to secure its feet. · An allowable length of the connecting pipe is up to 15 m. · An allowable head level is up to 6 m. · A place where the drain water does not raise any problem.
