General Inspections
6.5.1 Monthly Inspections
A general inspection should be performed on a
regular basis (monthly) for safety items. Items to
inspect include all wiring, flex hoses, and other
items. If a damaged item is viewed, call your local
BeaconMedæs service technician for a thorough
inspection and report of findings
6.5.2 Every Six Months
A thorough inspection of the vacuum pump
cooling air intake and discharge grating should
be performed at least every six months or more
frequently if conditions require. If a dust/dirt
buildup is visible, clean the grating to remove the
buildup. Excess dust/dirt buildup in these areas
will prevent air from cooling the vacuum pump,
affecting performance of the vacuum system.
6.5.3 Oil Leak
If upon inspection of the vacuum system, a
noticeable amount of oil is seen on the base of
the system or on the floor around the system,
immediate action is required to prevent the
possibility of injury. Using an oil absorbent or
like product, absorb the oil on the base frame
or floor to remove the potential of slipping. Call
your local BeaconMedæs service technician for
a thorough inspection of the vacuum pumps.
