(i.e. fuses, transformer, etc.).
check for proper motor starter overload
rating against full load amps on motor
nameplate. adjust or replace overloads as
required.
ensure drum is properly sealed against drum
lid package. ensure drum lid package is prop-
erly installed (refer to figure 13).
check motor current draw and close
volumetric control damper or silencer
damper until amperage fLa is below full
load rating of motor.
close dampers to increase static pressure
or install orifice plate in a branch duct.
inspect and reinstall cartridge filters (refer
to Section 6), gasket end first.
replace damaged filter(s) with new
