Maintenance
Vacuum Pump Maintenance
(Refer to pump manufacturer’s manual for specific
maintenance instructions)
The total function of the unit is based around the perfor-
mance of the vacuum pump. Heat transfer used to
raise the temperature of the solution is gained from the
air drawn by the vacuum pump and solution is removed
from the carpet with the vacuum suction of the vacuum
pump. General maintenance actions for the vacuum
pump as listed in this manual are vital to prolonged
vacuum pump operations. Daily lubrication of the
pump is required to avoid seizure of the system. Also,
waste tank filters and strainers must be maintained to
prevent unwanted debris from entering the vacuum
pump.
DO NOT service this unit while it is running. The
high-speed mechanical parts as well as high
temperature components may result in severe
injury, severed limbs, or fatality.
NOTE: Use the hour meter as a guide for coordinating
the maintenance schedule.
