Ensure that the ceiling isstrong enough to support the weight of the unit. Beforehanging the unit, test the strength of each attachedsuspension bolt.(1) Before suspending the unit from the ceiling, determine thepitch of the suspension bolts referring to the dimensionaldata given previously. (Figs. 3-1 and 3-2)(2) Screw in the suspension bolts allowing them to protrudefrom the ceiling as shown in Fig. 3-3. (Cut the ceilingmaterial, if necessary.)(3) Suspend and fix the indoor unit as shown in Fig. 3-6 usingvibration absorbers, sound insulation brackets and thematerial shown in Fig. 3-5.
