3.HOW TO INSTALL THE INDOOR UNIT

4-Way Air Discharge Semi-Concealed Type (X Type) 3-1. Preparation for Suspending

This unit uses a drain pump. Use a carpenter’s level to check that the

Xunit is level.

3-2. Suspending the Indoor Unit

(1)Fix the suspension bolts securely in the ceiling using the method shown in the diagrams (Figs. 3-1 and 3-2), by attaching them to the ceiling support structure, or by any other method that ensures that the unit will be securely and safely suspended.

(2)Follow Fig. 3-2 and Table 3-1 to make the holes in the ceiling.

3-3. Placing the Unit Inside the Ceiling

(1)When placing the unit inside the ceiling, determine the pitch of the suspension bolts using the supplied full-scale installation diagram. (Fig. 3-4)

Tubing and wiring must be laid inside the ceiling when suspending the unit. If the ceiling is already constructed, lay the tubing and wiring into position for connection to the unit before placing the unit inside the ceiling.
