20.6 Optional Equipment
Dampers Check linkage when applicable and tighten set screws as required. All moving
parts of dampers should be cleaned and then thoroughly lubricated with a
light molybdenum oil in aerosol can. Dampers furnished with stainless steel
side seals should also have the seals lubricated generously. Dampers should
then be manually operated several times until linkages and blades operate
freely. Reconnect linkages and check dampers for proper operation.
See Page 65, Section 13.
Filters Filters should be checked for dirt restriction on a monthly basis (or as
required). Replace filters with filters of equal specification when they appear
dirty.
NOTE: When using Rapid Engineering LLC supplied disposable polyester fil-
ters, they must be inserted with the white media side facing the inlet of filter
section. When using Rapid Engineering LLC supplied permanent aluminum
mesh or disposable filters, they must be inserted with the arrow on the filter
pointing in the direction of airflow (toward the air handler).
See inlet hood or filter section for filters. See Page 29, Section 11
