2. HOW TO INSTALL THE INDOOR UNIT
2-1. Suspending the Indoor Unit
This unit uses a drain pump. Use a carpenter's level to
check that the unit is level.
2-2. Preparation for Suspending
(1)
Fix the suspension bolts securely in the ceiling
using the method shown in the diagrams (Figs.
2-1 and 2-2), 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. 2-2 and Table 2-1 to make the holes
in the ceiling.
