Maintenance
Key Checkpoints
Note: Initiation of a planned preventative maintenance
program will assure that your unit has optimum perfor-
mance, a long operating life, and a minimal amount of
"down" time.
Engine Coolant System (Radiator)
Maintenance
Your engine radiator coolant system is an important
part of the power plant operation. Follow the recom-
mended coolant system maintenance in the Mainte-
nance Schedule in this manual and your engine
owner's manual. Refer any additional questions to your
dealer.
External Fuel Pump Maintenance
The power plant for the unit receives fuel from the main
fuel tank of your van/truck. An external fuel pump that
provides this fuel is located on the underside of the van/
truck. Loose fittings and hose connections will cause
your unit to perform poorly. Follow the recommended
fuel pump maintenance in the Maintenance Schedule
in this manual. Refer any additional questions to your
dealer.
Chemical Supply System Maintenance
The chemical supply system pulls chemicals from your
chemical bottle utilizing a pump that works off the
solution pump pulsing. Any clogged filters or loose
connections will result in a chemical supply system
malfunction or a malfunction at the cleaning tool. Main-
tenance of the solution outlet check valve and screen
are vital to effective cleaning operation and minimal unit
downtime. Additionally, the hoses related to supplying
water and chemical to the outlet manifold are under
high pressures and experience thermal expansion and
contraction. Periodic inspections of these hoses for
tears, cracks, and failing connectors are necessary to
avoid unwanted leaks. To keep your chemical system
functioning properly, follow the chemical pump and
solution outlet maintenance in the Maintenance
Schedule in this manual. Refer any additional
questions to your dealer.
Heat Exchanger System Maintenance
The heat exchange system in your unit transfers
energy between the engine’s exhaust and blower
discharge air to the solution supply system. The heat
transfer of this system is highly dependent on the
surface area contact in the heat exchanger cores
located in the heat exchanger box. This surface area
amount is adversely minimized when the supplied
water is not softened to recommended levels. Hard
water will result in scaling on the inside walls of the heat
exchanger tubes. It is recommended that you use a
dealer approved water softener to avoid premature
heat exchanger core failure. Contact your dealer for
advice on the water hardness levels in your area.
Additionally, the heat exchanger tubes are very
sensitive to freezing conditions. As the water freezes
during cold conditions, it expands in the heat
exchanger tubes and causes damage. Often the tubes
are cracked and require the replacement of the heat
exchanger core. Refer to the Freeze Protection instruc-
tions section in this manual. Refer any additional
questions to your dealer.
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.
