1.4SafetyRegulations
1.4.1SafetyRegulationsforthe Blowers
1)Undernormaloperation, theblowerswill generatehightemperature. Do
not touchblower's casetoavoidanyphysicalinjury.
2)Undernormaloperation,theblowermotor's currentloadingwill increaseor
reduceaccordingtoairpressure's changeaccordingly.Whileinstallation,
an adequatemotoroverload protection switchshouldbeinstalledwithfull
loadingtest, toensureoperatingsafelyunderfull-loadingtoavoidmotor's
damage.
3)Toavoidanyblock materials, dust, powder, fiberparticlesandwaterdrops
enteringtheblower, and hencecausethedeficiencyof itsperformance.
Thismachine iswell designed withair filters,sopleaseclean up thefilter
withanyforeignparticles(recommended toclean up thisfilterweekly).
4)Clean the blowersbothinternalandexternalparts(especiallyforthe fan
coolingpath),andremovesurfacedust if necessary. Ifmoredustsare
accumulated, itwill causedeficiencyforventilation,temperaturerising,
vacuumpowerreduced, vibration increasedand soit will causemachine
