LOUVERS
Option CD58,
60° Discharge Nozzle
After the unit is suspended/mounted, install the air directional louvers or optional nozzle. If an optional nozzle is
being installed, follow the instructions included with the nozzle. If a nozzle is not being used, install the louvers
in the discharge opening(s).
Louvers and springs are in the hardware kit shipped with the heater.
Before actually installing the louvers, note the louver curve and determine how the louvers should be positioned
to provide the optimal throw pattern. Opening is square so louvers may be installed in any direction. Louvers
may be installed with the curve all the same direction (either way) or the right half one way and left the other
as illustrated above.
1) With the wider section of the louver facing out of the heater, place one of the compression springs over the
tab on the notched end of a louver. The end of the louver with the spring will t in any direction in the square
opening. How the louver turns depends on which end of the louver is inserted rst.
2) Depending on the throw pattern selected, push the louver tab with the spring into a hole in the discharge
opening and insert the louver tab on the other end into the corresponding hole on the opposite side.
3) Airow direction depends on how the louvers are installed (see illustration above).
Option CD32 consists of additional louvers that are installed perpendicular to the standard individually adjust-
able louvers. By installing the optional perpendicular louvers, the two sets of louvers can be adjusted to direct
airow in any of the four directions, enabling the installer to select and increase or decrease the coverage
area.
Option CD57 is a 30° angle discharge nozzle. Option CD58 is a 60° angle discharge nozzle. Option CD59 is a
30° angle discharge nozzle with 4-way louvers. A nozzle may be installed at each discharge air opening in any
direction. NOTE: Do not install 4-way louvers with a 60° nozzle.
Nozzles should be attached after the unit is suspended. Follow the installation instructions in the nozzle pack-
age.
Standard louvers are installed in the nozzle opening as shown in the photo on the left.
