6-2. Suspending the Indoor Unit Depending on the ceiling type: • Insert suspension bolts (Fig. 1-34) or • Use existing ceiling supports or construct a suitable support (Fig. 1-35).

Air outlet duct Suspension bolt Bolt anchor Air intake duct It is important that you use extreme care in supporting the indoor unit inside the ceiling. Ensure that the ceiling is strong enough to support the weight of the unit. Before hanging the unit, test the strength of each attached suspension bolt. Air outlet grille Indoor unit Air intake grille (1) When placing the unit inside the ceiling, determine the pitch of the suspension bolts referring to the dimensional data as shown in Fig. 1-32 and Table 1-8. Tubing must be laid and connected inside the ceiling when suspending the unit. If the ceiling is already constructed, lay the tubing into position for connection to the unit before placing the unit inside the ceiling. (2) Screw in the suspension bolts allowing them to protrude from the ceiling (Fig. 1-34). (Cut the ceiling material, if necessary.) (3) Thread the 3 hexagonal nuts and 2 washers (field supply) onto each of the 4 suspension bolts (Figs. 1-36 and 1-37). Use 1 nut and 1 washer for the upper part, and 2 nuts and 1 washer for the lower part, so that the unit will not fall off the suspension lugs. Ceiling material Fig. 1-38 6-3. Installing the Drain Pipe (1) Prepare standard hard PVC pipe (O.D. 1-17/64" (O.D. 32 mm)) for the drain and use the supplied hose band to prevent water leaks. The PVC pipe must be purchased separately. The transparent drain part on the unit allows you to check drainage. (Fig. 1-39) CAUTION Do not use adhesive tape at the drain connection port on the indoor unit. Insert the drain pipe until it contacts the socket, and then secure it tightly with the hose band. Do not use the supplied drain hose bent at a 90° angle. (The maximum permissible bend is 45°.) 1-121
