“
RECOMMENDED ACTION
” suggests repair
procedures.
NOTE: THIS TABLE IS INTENDED AS A DIAGNOSTIC
AID ONLY. FOR DETAILED REPAIR PROCEDURES,

WARNING
Disconnect electrical power
source and allow all rotating
equipment to stop completely
before inspecting or servicing the
unit. Failure to do so may result in
personal injury or death from elec-
trical shock or moving parts.
Disconnect electrical power prior
to access into a fan or ductwork.
Even when locked out electrically,
fans may cause injury or damage if
the impeller is subject to “wind-
milling.” The impeller should be
secured to physically restrict rota-
tional movement. Failure to secure
impeller can cause severe per-
sonal injury or death.
