Run the drain hose at a downward sloped angle. 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 the waved shape. 50 mm or more Fig. 10-3-18 Carefully arrange the pipes so that none of the pipes 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 condensation can result in machine performance trouble, be sure to insulate both connecting pipes. (Use polyethylene foam as insulating material. ) When bending a pipe, be careful not to crush it. Do not put the drain hose end into water. Do not put the drain hose end in the drainage ditch. Fig. Put water in the drain pan and make sure that the water is being drained outside. When connecting extension drain hose, insulate the connection part of extension drain hose with shield pipe.
