NOTE The hole should be made at a slight downward slant to the outside. Indoor side Outdoor side PVC pipe (not supplied) INSIDE Fig. 1-200 Wall OUTSIDE 1. Specifications * If the drain hose is routed through the left side, refer to Fig. 1-198, and follow the procedure above to install the hose. Reattach the rubber stopper removed earlier onto the right side. The rubber stopper can be inserted easily by using a screwdriver or similar tool to press the stopper into the drain port on the main unit. Screwdriver Drain port Press the stopper into the main unit drain port as far as it will go. Rubber stopper Unit drain port Hose band (supplied) Hard PVC pipe (VP20 not supplied) Cut at slight angle PVC pipe Slight angle Fig. 1-201 Drain hose (supplied) Do not use adhesive. Adhere with PVC adhesive. Drain insulator (supplied) Unit: inch (mm) (1) Drain hose connection 1 The drain hose is connected below the refrigerant tubing. (2) Installing the drain hose First insert the drain hose (supplied) to the hose band (supplied) and then install the drain hose to the unit drain port. Insert until the drain hose bumps to the end. Attach the hose band to make the fixed portion 45°upper gradient according to a vinyl tape (not supplied) of the drain hose (supplied). (Fig. 1-203) Hose band screw torque is 2.6 - 3.0 lbf·inch (30 - 35 N·cm). Wind the vinyl tape not to blow up the hose band. Connect both the drain hose and PVC pipe (VP20 or similar material, not supplied). Insert until the PVC pipe bumps to the end and adhere with PVC adhesive. CAUTION Wrap the drain insulator (supplied) between the connection of the drain hose and tubing not to expose the copper tubing. Also, wrap the hose band together. Wrap the hose band with the drain insulator, where the screw is located facing upward (Fig. 1-203). Then, tighten the insulator with a vinyl tape not to cause the detachment. If the tubing parts remain exposed, condensation may occur. Be sure to use the supplied drain hose. If other commercially available hose bands are used, the drain hose may become pinched or wrinkled and there is danger of water leakage. Therefore be sure to use the supplied hose bands. Connect the drain pipe so that it slopes downward from the unit to the outside. (Fig. 1-202) Hose band Vinyl tape Drain insulator Vinyl tape Drain insulator CAUTION Hose band Fig. 1-203 The indoor unit should be slightly tilted downward toward the drain pipe connection side as shown in figure below so that the wastewater can flow smoothly without being trapped in the middle. (Fig. 1-204) Ceiling Approx. 1° Downward slant: min. 1/100 Upward slant: Diagonally right down (front view) (Ex.: Diagonal-right-backwards) Correct Incorrect Fig. 1-202 Never allow water traps to occur in the course of the piping. Insulate any piping inside the room to prevent dripping. After the drain piping, pour an appropriate amount of water into the drain pan through the opening on the side of the air discharge port. Check the water draining smoothly. Ceiling Approx. 2° Diagonally backward (side view) Fig. 1-204 1-174
