Mounting the Ceiling Cassette
If needed, a cardboard template is included with each unit to act as an installation guide to ensure that the
ceiling tiles are cut to the proper size and threaded rods are placed in the right locations to suspend the unit.
ATTENTION: Before discarding the carton and/or packaging materials, locate the installation template:
The 12/18K template is tucked around the top of the unit and is visible.
The 24K template is tucked inside the lid of the carton - pull out this cardboard insert from the lid, as this is the
template. Note: It may not be visible; as the template information is printed on the opposite side.
If using the cardboard template:
1. Center it onto the ceiling in the location where the ceiling cassette is intended to be mounted. Mark the
locations for the threaded rods.
2. Install or anchor threaded rods in these locations – The threaded rods should be properly attached to
the structure per any local or national building codes before suspending the unit.
3. Mark and make the opening in the ceiling for the unit.
Note: Depending on whether the ceiling is new or existing, the template can be attached to the indoor unit
using the screws that contain a washer and lock washer for mounting the panel onto the unit.
Once the template is attached to the unit, the unit can be suspended or set into position, while the template is
used to make the proper cuts into the ceiling tile and/or location markings for the threaded rods.
Once the threaded rods are installed and the opening is made, the ceiling cassette can begin to be suspended.
1. Start by placing a nut and washer onto the end of one
of the threaded rods.
2. Then place the end of the same threaded rod through
the installation flange of the unit.
3. Quickly place another washer followed by a nut onto
the end of the threaded rod below the installation
flange of the unit and hand tighten the bottom nut.
4. Repeat for all four threaded rods.
5. Now that the unit is suspended at all four points,
tighten all the nuts above and below the flange to
secure the unit.
ATTENTION: Be sure that the unit is level and that all clearances are maintained.
