UNIT LOCATION/INSTALLATION

8-504.6
A cardboard template for ceiling cut-out and rod positions is
included with the unit.
Positioning Electro-Mechanical Thermostat
In addition to positioning the unit correctly, it is very
important to locate the wall mounted thermostat in the
optimum position to ensure good temperature control.
Therefore the installation should be selected with the
following points in mind:
1. Position the thermostat approximately 48 inches above
floor level.
2. Do not position thermostat where it can be directly
affected by the unit’s discharge air stream.
3. Avoid external walls and drafts from windows and doors.
4. Avoid positioning near shelves and curtains as these
restrict air movement.
5. Avoid heat sources e.g. direct sunlight, heaters, dimmer
switches and other electrical devices.
INSTALLATION
IMPORTANT
Make sure the ceiling grid is supported separately from
the appliance. The ceiling must not be supported by any
part of the appliance, fascia or any associated wiring or
pipe work.
Hanger Bolts
The hanger bolts can now be installed (use 3/8” all thread
rod) at the centers shown in Figure 4.1 and Table 4.1.

of the cassette case with the guide pointing away from

2. Adjust the height of the cassette until the guide is level
with the bottom of the false ceiling.
