Note:
If the unit is installed in a ceiling that does not have removable tiles, make allowances for
servicing the unit by creating an access hole. If the unit is installed more than 39.4 in. (1 m)
above the floor, the access hole must be the size of “B.” If the unit is installed less than
39.4 in. (1 m) above the floor, the access hole must be the size of “A” +“B” both.
