MAINTENANCE FUNDAMENTALS, CONT'D: HONEYCOMB AIR DIFFUSERS

Preventive maintenance should be performed
every 30 days unless conditions warrant a
more frequent replacement cycle.
1. Honeycomb Air Diffuser Removal
Honeycomb is located in discharge air duct.
A. Wedge a non-metallic device of suitable strength
(such as a ballpoint pen) between the honeycomb and
the end panel.
Caution! Use care not to dislodge the heating wire (that
prevents condensation on the lamp assembly).
B. Apply pressure to collapse the honeycomb to allow it
to be pulled out of honeycomb retainer.
C. Pry downward and away from honeycomb retainer.
• Clean honeycomb with warm water and soap
solution.
• Submerse if necessary.
• Use brush to dislodge stubborn or sticky residue.
• Dry by using vacuum's blow mode (vs. suction
mode).
2. Honeycomb Air Diffuser Installation
D. Squeeze honeycomb to allow it to fit into
honeycomb retainer.
E. Carefully slide honeycomb into place.
F. Adjust honeycomb so that it fits flat against retainer.
It must not be wavy or out of position.
Note: For honeycomb air diffusers in other locations,
