CASSETTE CHASSIS pOSITIONINg ANd INSTALLATION
Ceiling opening:
•
In existing construction, remove enough
ceiling panels to provide clearance space
for mounting unit to ceiling joists.
• Before beginning the installation, inspect
the unit location, test the strength of the
ceiling joists to insure they will support
the weight of the unit.
• Determine mounting method:
- On wooden beams use threaded rods,
washers, and nuts to suspend support
brackets.
-
With metal structures, secure threaded
rods on an existing angle or install a
new support angle.
-
On newly built concrete slabs secure
threaded rods with inserts and em
-
bedded bolts.
-
For previously built concrete slabs install
hanging bolts with an expansion anchor.
A template for ceiling cut-out and rod posi
-
tions can be found with the Cassette unit.
-
Follow local building codes for required
safety cables, braces, etc.
An opening in the false ceiling will have to
be cut to the following sizes:
NOTE:
Make sure the ceiling grid is sup-
ported separately from the Cassette. The
ceiling must not be supported by any part of
the Cassette unit, fascia or any associated
wiring or pipe work.

THERmOSTAT
An optional thermostat can be obtained
through EMI or your local distributor. In
addition to positioning the Cassette cor
-
rectly, it is very important to locate the wall
mounted thermostat in the optimum posi
-
tion to ensure good temperature control.
The installation should be selected with
the following points in mind:
1. Position the thermostat approximately
5 ft. (1.5m) above floor level.
2. Avoid external walls and drafts from
windows and doors.
3. Avoid positioning near shelves and cur
-
tains as these restrict air movement.
4. Avoid heat sources (direct sunlight,
heaters, dimmer switches, etc.)
5. Seal wiring holes in the wall behind the
thermostat to avoid drafts.
