9 English7. DRAIN PIPING WORK(1) Carry out drain piping.• Carry out drain piping so that drainage can ensured.• Drain piping can be connected from the following direc-tions: For right rear/right side, refer to Fig. 18 of ‘‘6.REFRIGERANT PIPING WORK’’, and for left rear/leftside, refer to Fig. 21.• When conducting left rear/left side drain piping, removethe protection net. Then, remove the drain socket cap andinsulation material applied to left side drain socket andapply them to the right side drain socket. When doingthis, insert the drain socket cap all the way in to prevent awater leakage.After the drain hose (1) (accessory) installing, attach theprotection net by reversing the steps taken to remove it.(Refer to Fig. 22)• Select the piping diameter equal to or larger than that ofthe drain hose (1) (accessory) (polyvinyl chloride piping,nominal diameter 20mm, outside diameter 26mm).• Install the drain piping as short as possible with down-ward inclination of 1/100 or more by avoiding air stagna-tion. (Refer to Fig. 23 and Fig. 24)(It may cause abnormal sound such as bubbling noise.)CAUTIONIf drain stagnates in the drain piping, the piping may beclogged.• Make sure to use the attached drain hose (1) and metalclamp (2). Also, insert the drain hose (1) into the root ofthe drain socket, and tighten the metal clamp (2) at theroot of the drain socket tightly.(Refer to Fig. 25 and Fig. 26)(Install the metal clamp (2) so that the tightening part is inthe range of about 45°as shown in the Fig. 26.)(Do not bond the drain socket and drain hose. If so, main-tenance and inspection for the heat exchanger and oth-ers cannot be conducted.)CAUTIONIf an old drain hose or an elbow or a clamp is used, it maycause water leakage.• Bend the tip of the metal clamp (2) so that the sealingmaterial does not bulge. (Refer to Fig. 26)• When performing insulation, wind the large sealing mate-rial (Large) (8) attached starting from the base of themetal clamp (2) and drain hose (1) in the direction of thearrow.
