FIGURE 6 - Suspended Mounting
B. Four (4) factory installed ¼" threaded inserts are located on the
top of the unit for top suspension mounting; on units comprised
of modules use the outer threaded inserts. To eliminate the
slight deflection of longer units, the inner threaded inserts may
also be used. See Figure 6
C. Determine the exact mounting location of the air door unit.
D. The top of the unit is provided with two knockouts on each side
allowing for a left or right hand power connection. Remove the
wiring tray cover; on units that are comprised of modules, re-
move the wiring tray cover that is located closest to the electrical
rating nameplate. Remove the required knockouts and attach
necessary electrical hardware. Save the wiring diagram found
inside of wiring tray. See Figure 7
E. Attach ¼" threaded rods, or other suitable hardware to the top
mounted threaded inserts.
F. Proceed to Section V - Electrical Connections
FIGURE 7 - Electrical Connections
V. ELECTRICAL CONNECTIONS
All electrical wiring and connections MUST be performed by
qualified personnel in accordance with the National electrical
Code ANSI/NFPA No. 70 (latest edition) or, in Canada, the Cana-
dian Electrical Code, Part 1-C.S.A. Standard C22.1 and local codes
and regulations.
A. Check the rating nameplate on the top of the unit for supply
voltage and current requirements. See Figure 7. A separate line
voltage supply with a suitable branch circuit protection device
should be run directly from the main electrical panel to the unit.
A disconnect switch for each branch circuit is a required part of
this installation. See Tables 2 & 3
B. All field wiring must be copper with a minimum insulation of
60°C within approved conduit. If any of the wire supplied with
the unit must be replaced, it must be replaced with copper wiring
with a minimum insulation of 90°C.
C. Remove the wiring tray cover; on units that are comprised of
modules, remove the wiring tray cover that is located closest to
the electrical rating nameplate (if it has not already been done).
D. Electric heated units are factory equipped with a unit mounted
solid state temperature sensor cable (for the Intelliswitch
thermostat) located in the wiring tray. Depending where the
temperature is to be measured; the sensor may be left in the
wiring tray or it may be located outside of the unit.
If the unit is unheated, equipped with a steam/water coil or the
sensor will be left in the wiring tray, skip to step E, otherwise
continue.
Note: Sensor storage temperature range is -76º F to 302º F (-
60º C to 150º C). Sensor functioning temperature range is
32ºF to 100ºF (0º C to 38Cº).
1.
Remove 1/2" bushing taped to the back of the wiring tray
cover and set aside.
2.
Determine mounting location of the temperature sensor
(do not mount at this time).
