Installation instructions
1.- For correct installation and optimum operation the di󰀨user must be installed with the o󰀨set angle
label located on the top side of the di󰀨user (Figure 1).
Use the pre-drilled holes to securely fasten the di󰀨user to the duct or wall.
Once fastened, ensure that the moving part of the di󰀨user does not touch or rub against any external
obstruction.
To install the DF-47 TR di󰀨user:
Unless otherwise dened, the di󰀨user will be set in the factory to 0º (with respect to the horizontal
axis) for cold air and -20º for hot air.
On site, use the following steps to adjust the o󰀨set angle:

“The numbers should be correctly displayed, with the grade label on top and right“
2.- Adjusting o󰀨set angle of the temperature-adjustable DF-47-TR.
The DF-47-TR di󰀨user has the capability of being directed up at an angle of 20º (with respect to the
horizontal axis) to supply cold air (Air Temp. < 20ºC) or down 20º to supply hot air ( Air Temp. > 30ºC).
In general, the correct angle will depend on the supply air temperature, the height of the installation
and the area to be covered. As such, it is recommended that this is evaluated during each project.

3.- Adjusting optimum angle for cold air.
Using the o󰀨set angle label (Fig. 1) to measure the o󰀨set, loosen screw 2 (gure 2); rotate the
di󰀨user to the desired angle; move screw 2 along slot 1 (gure 2) until it touches the moving part of
the di󰀨user and re-tighten screw 2.
The maximum possible o󰀨set with respect to the horizontal is 20º down (gure 2).
4.- Adjusting optimum angle for hot air.
Using the o󰀨set angle label (Fig. 1) to measure the o󰀨set, loosen screw 3 (gure 3) until the di󰀨user
reaches the desired angle and then tighten nut 4 against the support. The maximum possible o󰀨set
with respect to the horizontal is 20º upwards (gure 2).
