LOCATION AND MOUNTING
1. Hoffman electric heaters should be centered as
low as possible in the enclosure for optimum heat
distribution.
2. It is recommended that the heater be installed
on a panel for optimum performance. It may,
however, be mounted on any metal surface.
3. The heater should be mounted in a vertical
position with the terminal block at the bottom and
the air outlet openings at the top as shown.
4. Heaters should not be installed on wood or
other combustible surfaces.
5. Heat sensitive components should not be
placed above the heater discharge area.
6. The recommended clearances shown by the
shadowed area indicate the space that should be
kept free of components for safe operation of the
heater.
7. Four 10−32 UNF, self−tapping screws are
included for installation.
Thermal sensitive devices or materials may need to be
located further from the heater than the minimum
recommended distance.
