Positioning
The cassette installation position should be
selected with the following in mind:
1. Pipe work, electrical connections, control
box and condensate pump access panels
should be readily accessible. Refer to the
cassette dimensions in the back of this
manual.
2. The unit should be positioned at least 5
ft. (1.5m) from a wall or similar obstruc-
tion.
3. Position the unit as close to the center
of the room as possible to ensure air is
distributed evenly.
4. Position the unit so that the discharge
air does not blow directly on the remote
thermostat, if used.
5. The unit should not be positioned directly
above any obstructions.
6. The condensate drain should have suf-
ficient fall — 1" per 10' (8 mm/m) in
any horizontal run between cassette and
drain.
7. Maximum condensate pump lift is 36"
(0.9m).
8. There should be a minimum 1" (25.4mm)
clearance above the depth of the cassette
and the false ceiling for proper instal-
lation. See Figure 5, Page 10. (See the
cassette dimensions in the back of this
manual for cabinet sizing).

Remote thermostat
A remote thermostat can be obtained through
EMI or your local distributor. The remote
thermostat is required for CACG/CAHG
units, optional for CACH/CAHH units.
In addition to positioning the cassette cor-
rectly, it is very important to locate the wall
mounted thermostat in the optimum position
to ensure good temperature control. The
installation should be selected with the fol-
lowing points in mind:
1. Position the thermostat approximately 5
ft. (1.5m) above floor level.
2. Avoid external walls and drafts from win-
dows and doors.
3. Avoid positioning near shelves and cur-
tains as these restrict air movement.
4. Avoid heat sources (direct sunlight, heat-
ers, dimmer switches, etc.)
5. Seal wiring holes in the wall behind the
thermostat to avoid drafts.
