Operations
Upholstery Cleaning
Upholstery tool, (See Options Section)
1. To protect fabrics, reduce solution temperature as
needed by opening the solution temperature con-
trol valve on the lower front panel. Engine speed
may also be reduced slightly to reduce heat and
vacuum.
Shutdown and Daily Maintenance
1. Close chemical metering valve.
2. Allow the unit to run for 2 minutes with the vacuum
hose disconnected to remove moisture. Spray
water displacing lubricant into the vacuum lubrica-
tion cup. This will prevent corrosion due to mois-
ture.
3. Set engine throttle at idle position and allow the
water temperature to cool down, utilizing the tem-
perature control valve in the open position to bleed
off residual hot water left in the system.
4. Close temperature control valve and turn off igni-
tion switch.
5. Disconnect all hoses and tools.
6. Drain waste tank and rinse with clean water.
De-Flooding Operations
De-flooding operations involve removal of water from
carpet and flooring. This differs from normal cleaning
operations in that no water or solution is required. An
automatic waste pump-out is highly recommended for
all de-flooding operations due to the large amount of
water removal often required.
1. Start unit.
2. Set pressure regulator at 100 psi.
3. Shut off solution pump.
4. Begin de-flooding operations.
5. Under almost all conditions, the unit will sufficiently
cool itself. If you find yourself operating in extreme
heat: Hook up a water supply; turn on the water
pump at 100 psi, and crack the temperature control
valve slightly to provide additional cooling to the
solution system.
Freezing Protection
If the unit is exposed to freezing weather the water
in the unit may freeze, causing SERIOUS DAMAGE
to the unit. To avoid this, the following is recom-
mended during the cold weather season.
When the unit is not in use, always park it in a heated
building.
While in operation, avoid long shutdowns as the unit
provides heat while running. Shut it down just prior to
leaving for the next job.
If a heated building is not available, we recommend that
you winterize the unit with anti-freeze. At present, it is
only possible to winterize units, which do not have an
auxiliary water tank. Units with auxiliary water tanks
must be stored in a heated building when not in use.
Overheating Protection
Air cooled engines rely on the flow of air over the
engine for cooling operations. Ensure that there is
sufficient air flow in the van. Never operate the unit
with all the vehicle doors closed and no alternative
ventilation system.
This unit must be operated with the vehicle or
trailer doors open in order to ensure adequate
engine ventilation.
